Simple adverbs

"Worrying is quite common – some people worry more than others because it can be something they’re born with." (Grové 2019) (modifier, modifying the adjective 'common')

"The newly-discovered insects appear rather underwhelming, preserved as small brown fragments of wing cases." (McDonald and McNamara 2020) (modifier, modifying the adjective 'underwhelming')

"This spot is actually a cyclone, similar to hurricanes and cyclones here on Earth." (Kedziora-Chudczer 2022) (adverbial of place)

Compound adverbs

"Negative blood types are somewhat rare." (Helms 2019) (modifier, modifying the adjective 'rare')

"Between the creation and destruction of ocean plates, sediments collect on the sea floor and provide an archive of Earth’s history, the evolution of climate and life that is available nowhere else." (OConnell 2019) (post-modifier, modifying the adjective 'available')

Suffix -ly adverbs

Words made by modifying an adjective with the suffix -ly, such as rapid-rapidly, exact-exactly, evident-evidently.

"Luckily glasses can easily fix the problem." (Mackey, Lee, and Wee 2021) (1. adverbial, 2. modifier, modifying the verb 'fix')

"It breaks down very slowly into lead." (Skromne 2022) (1. modifier; 'very' modifies 'slowly', 2. post-modifier, 'slowly' modifying the verb 'breaks down')

Fixed phrases

Words in a phrase which never changes, such as at last, of course, in addition, in other words, for example, even so, etc. These are almost exclusively adverbials.

"For example, is Japanese more difficult than English?" (Sorace 2023)

"In fact, air’s mostly made of nitrogen." (Lynch 2020)

"At the time, that was seen as an improvement." (Stewart and Yohe 2022)

"Since then there has been an ever increasing assault on dark." (Stevens 2015)

"The lunar-mangrove cycle is clearly visible from above." (Saintilan 2022)

"It would probably take a chemist about a year to make one compound and there are 6,903 two-atom compounds in theory." (Addicoat 2023) ('about' is an approximator and modifies the noun phrase 'a year' )

"There are estimated to be nearly 8 million species of animals living today, making up the majority of Earth’s documented biodiversity and inhabiting almost all of its environments." (Anderson 2023) ('almost' modifies the noun phrase 'all of its environments')

"That stops water from running directly into our eyes." (Phelps and Moro 2021) (the adverb 'directly' modifies the prepositional phrase 'into our eyes' )

"So the next time you see a plant growing straight, take notice of whether light is directly above it." (Montgomery 2022) (the adverb 'directly' modifies the prepositional phrase 'above it' )

"Nations are trying to keep the temperature rise well under 2℃." (Doddridge 2022) (the adverb 'well' modifies the prepositional phrase 'under 2℃' )

"Take the example below, from a recent academic paper -– a genre that has traditionally been perceived as formal." (Brezina 2021) (the adverb 'below' post-modifies the noun phrase 'the example' )
adverbial: noun COUNTABLE GRAMMAR An adverb phrase used to provide circumstantial information about a clause, to indicate the writer’s stance, or to link units of discourse by indicating their relationship.
Examples:
Circumstance Adverbials

"To make a viable seed, pollen from one part of the flower must fertilize the ovules in another part of the flower" (Harkess 2021). (location)

Stance adverbials

"While we think of perfect vision in humans as being 20/20, typical vision in dogs is probably closer to 20/75" (Dreschel 2020). (doubt, uncertainty)

"That means astronomers will have the chance to study these rings – and one day, hopefully, we’ll be able to answer all of your questions and more." (Kuhn 2020). (attitude)

Linking adverbials
See how linking adverbials are managed on the linking adverbials page.
adverbial particle: noun phrase COUNTABLE GRAMMAR A group of words which are often attached to verbs to create multi-word verbs with new meanings. They are also used to create extended prepositional phrases. Examples: about, across, along, around, aside, away, back, by, down, in, off, on, over, past, round, under, up. To create a multi-word verb (phrasal verb): sit down, stand up. To create an extended prepositional phrase: up in the sky, down in the dumps.
adverb phrase: noun COUNTABLE GRAMMAR A phrase containing an adverb as the head. This may be the only word in the phrase but it may also be modified by words, phrases and clauses. Most adverb modifiers express degree. Adverb phrases are not the same as adverbials.
"It seems our universe started very small and has been expanding ever since." (Lam 2020) ('since' is the head and 'ever' is the modifier; both are adverbs)

"The flashes of energy from the pulsar go past very fast and very often, so we know it is spinning incredibly fast." (Nicholson 2019) (3 examples here: 'fast' and 'often' are headwords, and 'very' and 'incredibly are modifiers; all are adverbs)

"Trees can die suddenly or quite slowly." (Stevens-Rumann 2023) ('suddenly' is a one word adverb phrase so 'suddenly' is the headword; 'slowly' is the headword in the adverb phrase 'quite slowly' and 'quite' is the modifier; all are adverbs)

"The newly-discovered insects appear rather underwhelming, preserved as small brown fragments of wing cases." (McDonald and McNamara 2020) ('rather' is the headword in a one word adverb phrase. It functions as a modifier, modifying the adjective 'underwhelming')

"Cartilage breaks down much more quickly than teeth or bones do, so it rarely gets fossilized." (Naylor 2022) ('quickly' is the headword in the adverb phrase 'more quickly than teeth or bones do'; 'more' is an adverb premodifier of 'quickly', and 'than teeth or bones do' is a post modifying comparative clause)
adverb phrase roles: noun phrase COUNTABLE GRAMMAR Adverb phrases may perform the following syntactic roles:

Modifier of an adjective or other adverb

"Oxygen is like food for fires – it makes them burn really bright." (Nolan 2019)

"They are truly amazing animals." (Cannell 2021)

deixis: noun UNCOUNTABLE PRAGMATICS Deixis refers to the way in which we identify references and their referents in context, especially references to place, time and persons. When we read or use a word like "this", "that", or "those" we know that these are pointers to something in the text and that we can retrieve that information. Even the word "the" is a deictic. It tells us that there is something specific that we can find within the text or in the world at large. Personal pronouns (I, you, he, she, it....), demonstrative pronouns (this, that, these, those), place adverbs (here, there), and time adverbs (now, then...) are the main deictics used in text. See also reference and the reference page.

dependent clause: noun phrase COUNTABLE GRAMMAR A clause which cannot stand alone as a separate sentence and only has sense when attached to a main clause. Also known as a subordinate clause.

It "depends" on the main clause, in this case providing a reason.

elaborate: verb INSTRUCTION WORD To provide further information about some aspect of item(s) mentioned in the task description. Used as an instruction word in a writing task description. This would normally be a secondary instruction in a task description. See the task analysis page for more information about understanding task instructions.
ellipsis: noun UNCOUNTABLE A cohesive device, similar to substitution, where an element is omitted because it can be retrieved from the context of the text. There are three types: nominal ellipsis, verbal ellipsis, and clausal ellipsis. See more about ellipsis on the ellipsis page.
ellipsis: noun UNCOUNTABLE The omission of a part of a sentence usually indicted by ellipsis points " . . . ". There should be three ellipsis points and there should be a space before and after each one.
embedding: noun COUNTABLE GRAMMAR The insertion of one phrase or clause inside of another (also known as nesting). Embeddings are common in complex noun phrases. See the noun phrase examples page.
empty subject: noun phrase COUNTABLE The pronoun "it" is used in some sentences (often concerned with time, weather and distance) as an empty (or dummy) subject. In these sentences "it" does not refer to anything - there is no referent to be found in the text. Examples: It's a long way to Tipperary. It's time to go. Contrast with "it" in the following text: "Earth’s spin is important for life. It causes day and night. It’s also important for ocean tides" (Laycock 2023). Here, "it" is referential: it refers to Earth’s spin.
Empty "it" is often used in academic writing in sentences with the structure: It seems/appears + that complement clause. "It appears that the psychological profiles of firstborns may have been over-generalised" (Sabolova 2020). This structure has two features which are useful in academic writing: 1) 'seems' or 'appears' introduces a hedging feature, and 2) like the passive voice, it avoids the use of first person pronouns thus introducing a (perhaps spurious) appearance of impersonal objectivity.

end note: noun COUNTABLE A note containing further information or explanations added to the end of a chapter, section or article.
end-focus: noun phrase UNCOUNTABLE GRAMMAR Known (given) information or information recoverable from preceding text tends to be placed at the beginning of a clause whereas newer information is normally presented later, often at the very end of a clause (where in speech it may be stressed). This principle of highlighting new information by placing it at the end of a clause in known as end-focus. This principle may be overruled where long complex structure are better placed at the end of sentence. See end-weight.
endophoric reference: noun phrase UNCOUNTABLE COHESIVE DEVICES Cohesive reference to something within a text. Endophoric reference is by far the most common type of reference and there are two types: anaphoric (pointing backwards in the text) and cataphoric (pointing forwards in the text). The outside skin of a cell is called the plasma membrane. It is made mainly of molecules called fats. ""It" points back (anaphorically) to "he outside skin of a cell" in the previous sentence. See also exophoric reference and the cohesion page.
end-weight: noun UNCOUNTABLE GRAMMAR The strong tendency in English to place longer, more complex structures towards the end of a sentence. Consider this sentence: "But it is not yet known if tai chi is better for improving these aspects over other types of exercise and mindful activities" (Nyman 2020). The weightier part of the sentence is at the end. We could rewrite this as "Whether tai chi is better for improving these aspects over other types of exercise and mindful activities is not yet known. In this case we have to hold a more complex structure in memory before we get to the shorter "not yet known" bit. It seems harder to process.
enumerate: verb INSTRUCTION WORD To provide a numbered list of item(s) requested in the task description. Used as an instruction word in a writing task description. See the task analysis page for more information about understanding task instructions.
enumeration: noun UNCOUNTABLE The ordered listing of items in a text. See how enumeration is used in a real text on the enumeration page.
epigram: noun COUNTABLE A very short piece of text saying much in a few words.
ergative verb: noun phrase COUNTABLE GRAMMAR A verb which can be used both transitively and intransitively. Example: "Technology will no doubt improve over the next 500 years, too" (Little and MacDonald 2021). improve is intransitive
"This will certainly improve sleep, and may reduce risk of later disease" (Stevens 2015). improve is transitive.
essay: noun COUNTABLE A piece of writing on a particular topic often written by students as a demonstration of their writing ability or their knowledge of a particular area of study.

euphemism: noun COUNTABLE FIGURE OF SPEECH A word or phrase used to substitute for an unpleasant, taboo, or offensive one.
evaluate: verb INSTRUCTION WORD To state your opinion about the value of the arguments, proposals, propositions etc. in the task description. Your opinions should be supported by evidence and/or reasoned argument. Used as an instruction word in a writing task description. See the task analysis page for more information about understanding task instructions.
eventive subject: noun phrase UNCOUNTABLE SEMANTICS An eventive subject is a subject which identifies an event. For example, "The way we do this is pretty cool" (Archibald 2021). "The way we do this" is the subject and it is clearly an event.

exclamation mark: noun phrase COUNTABLE PUNCTUATION An exclamation mark (!) is used to emphasise or draw attention to something. See the Exclamation Mark Page.
existence verbs: noun phrase COUNTABLE SEMANTICS Verbs of existence (or relationship) are verbs used to indicate a state or relationship which connects two entities. Examples of these verbs are the copular verbs be, seem, and appear. Other are concern, constitute, contain, define, deserve, exist, illustrate, imply, include, indicate, involve, lack, live, matter, owe, own possess, reflect, relate, remain, represent, reveal, sound, stay, suit, tend, vary. "That might seem strange, but don’t worry, it will all make sense soon" (Barton 2020). (copular verb) ; "For example, seeds contain a food source to help the new plant grow" (Lundgren 2019). (relationship) ; "This group includes species of wasps, flies, beetles and worms" (Ritchie 2022). (relationship) ; "Impact crater studies didn’t really exist until about 60 years ago" (Gibson 2021). (state of existence); "Other methods for pushing a spacecraft involve using electric or magnetic forces" (Impey 2021). (relationship). ; "We lived in small, nomadic bands, hunting and gathering" (Longrich 2020). (state of existence).
existential there: noun phrase COUNTABLE FUNCTION WORD A device for introducing new information in the subject position of a sentence. Usually only given (already mentioned or shared information) is placed in the subject position of a sentence but occasionally the subject is new information and it may be contained in a long clause which might seem clumsy at the beginning of a sentence. In this case the word "there" is used as an empty subject followed (usually by the verb "be") and then the new information. In the sentence "There's a reason why pizza is so popular.", the real subject is "a reason why pizza is so popular", and we could put this in the subject position and say "A reason why pizza is so popular exists." This is not too difficult to process but if we have a much longer subject it gets more difficult: "There are a number of other specific conditions that may also be associated with abnormal brain wiring" (Barker 2017). " To start the sentence with "a number of other specific conditions that may also be associated with abnormal brain wiring" as the subject would be inelegant to say the least. Here are some more examples: "There are three basic strategies for dealing with vinegar syndrome:..." (Ahmad 2020). "... there are several theories as to why tai chi may improve brain health" (Nyman 2020). "In the early 1990s, there was significant excitement in the field about the possibility of recovering DNA from dinosaurs" (Götherström and Dalén 2022). "Finally, there’s a discussion to be had about how specialists in different disciplines should work together" (Prendergast 2022).
exophoric reference: noun phrase UNCOUNTABLE COHESIVE DEVICES Non-cohesive reference to something outside a text. Exophoric reference is not simply the name of something; it is a signal that the referent may be found in the context of a situation outside of the text. Because of this it is difficult to give a suitable textual example. Most examples of exophoric reference take place in the context of conversations. See also endophoric reference.
explain: verb INSTRUCTION WORD To give clear reasons for something requested in the task description. Used as an instruction word in a writing task description. See the task analysis page for more information about understanding task instructions.
expletive: noun COUNTABLE GRAMMAR A word such as "it" or "there" which takes the syntactic place of another. Example: "There was no possibility of taking a walk that day." (Charlotte Bronte). See also empty subject and existential there.
exposition: noun COUNTABLE Text (in an essay, report or research paper) written to present information in a clear, measured, logical and well argued style.

external causer: noun phrase UNCOUNTABLE SEMANTICS An external causer is a subject which is the inanimate external cause of an event or condition. For example, "All kinds of factors influence the way people talk, including regional variations, age, ethnicity, education level and technology.." (Britt-Smith 2021). "All kinds of factors" is the subject and it clearly identifies a cause.
extract: noun COUNTABLE A short section of writing taken from another document.
extraposed subject: noun phrase COUNTABLE GRAMMAR A subject placed towards the end of a sentence rather than at the beginning with a 'dummy subject', it, taking its place at the beginning. Example: "It's hard being a student in a large class." The more normal SVC construction would be: "Being a student in a large class is hard". It would be easy to assume evolution works by continuously adding features to organisms, constantly increasing their complexity" (Guijarro-Clarke and Paps 2020). The more normal SVC construction would be: "To assume evolution works by continuously adding features to organisms, constantly increasing their complexity would be easy". The first version obeys the principle of end-weight.
extraposition: noun UNCOUNTABLE GRAMMAR The use of "it" in the subject position of a sentence to refer to a displaced (extraposed) clause (finite or non-finite). Example: "It would be easy to assume evolution works by continuously adding features to organisms, constantly increasing their complexity" (Guijarro-Clarke and Paps 2020). To turn this around and put the clause back in the subject position would result in "To assume that evolution works by continuously adding features to organisms, constantly increasing their complexity would be easy".

flow: noun UNCOUNTABLE "Flow" in academic writing is the sense which the reader gets that there is logical movement through the text, and that because of this the ideas in the text are not difficult to understand or relate to each other. Flow is achieved when the text has a clear organizational structure, paragraphs have topic sentences, supporting sentences relate directly to topic sentences, ideas are logically connected and there is a sense of coherence to the text. At a sentence level flow is enhanced by using simple, precise vocabulary and clear, concise syntax.

formulaic writing: noun phrase Writing which consists mainly of fixed words or phrases and/or clichés. There are many fixed phrases and idioms in English and, used correctly, are perfectly acceptable. But over-use can make a text tedious to read. However, if you are a non-native speaker of English learning to write academic text you may find resources such as the Academic Phrasebank quite useful.
freewriting: noun UNCOUNTABLE To write freely and quickly for a short timed period without regard to format, grammar punctuation etc. in order to generate ideas.
full stop: noun phrase COUNTABLE PUNCTUATION A punctuation mark (.) which marks the end of a sentence. Also known in American English as a period.

There are also genitives of time: "yesterday's rain"; genitives of measure: "eight hour's sleep", group genitives: "Marks and Spencer's cafe". Elliptic genitives: "South Korea’s income was more than ten times higher than Ghana’s (Teal 2016)" (Ghana’s income), and independent genitives: "Some disorders specifically associated with the condition include traumatic brain injury, Alzheimer’s disease, Parkinson’s disease, multiple sclerosis and stroke. (Barker 2017)". These are often reduced simply to Alzheimer’s, Parkinson’s.

hedging: noun UNCOUNTABLE The avoidance of absolute commitment to an argument or thesis by using words or grammar which introduce an element of doubt or tentativeness. This technique may also be used not because you have doubts about your argument but because it may be easier for your reader to accept your ideas if they are expressed less forcefully. See how hedging is managed on the hedging page.
hierarchy: noun COUNTABLE A system in which items are arranged according to their importance. Classification is related to hierarchy but they are not the same: a classification may or may not be hierarchical. How importance is decided and whether hierarchies arise naturally or are a human invention is debatable. "Hierarchies are everywhere. It is often argued that they are a social construct, invented to allow certain people (such as white men) to have power over others. But not everyone agrees." (Gonçalves 2018)
homograph: noun COUNTABLE A word which has the same spelling as another and which may have the same or a different sound, but which has a different meaning. Same spelling and same sound but different meaning: "A can of soup." "Can you open this for me, please?".

"Can you open this for me, please?" Same sound, different spelling but different meaning: "Have you seen a Polar bear?" "He can bend a steel bar with his bare hands." (True homonyms have the same spelling - so only the the first example is a true homonym; the second example is a homophone.) You need to be careful about the spelling of homophones when you proofread.
homophone: noun COUNTABLE A word which sounds the same as another, but has a different meaning or a different spelling or both. Same sound, different spelling and different meaning: "There's a hole in my bucket, dear Liza" "We have beautiful images of Jupiter which show striped, stormy clouds covering the whole planet" (Kedziora-Chudczer 2022).

hypernym: noun COUNTABLE SENSE RELATION A word which is at a higher level of generality than another. Example: a flower is a hypernym of rose. Similarly, a rose is a hyponym (the opposite of hypernym) of flower. Hypernyms are often used when we want to use a more general word to refer back to something more specific mentioned earlier in a text. Hyponyms are often used when we give examples: "The intense industrial processes [ …] strip away many beneficial nutrients such as fibre, vitamins, minerals and phytochemicals" (Hoffman 2022). "Nutrients" is the more general category (hypernym) and "fibre", "vitamins", "minerals" and "phytochemicals" are the more specific hyponyms.
hyphen: noun COUNTABLE A short line which connects two parts of a compound word. Self-help, eye-opener; See the Hyphen Page.
hyponym: noun COUNTABLE SENSE RELATION A word which is at a lower level of generality than another. Example: a rose is a hyponym of flower.

Hyponyms are often used when we give examples: "The intense industrial processes [ …] strip away many beneficial nutrients such as fibre, vitamins, minerals and phytochemicals" (Hoffman 2022). "Nutrients" is the more general category (hypernym) and "fibre", "vitamins", "minerals" and "phytochemicals" are the more specific hyponyms.

They are used in a variety of ways; as subject, subject predicative, extraposed subject, direct object, object predicative, as a noun phrase modifier, as an adverbial, and as an adjective complement. Direct object: "we need to worry about what’s happening on the largest island in the world" (Bamber 2020). Subject predicative: "One way around this problem is to see how the ice sheet responded to changes in climate in the past" (Bamber 2020). Adverbial: "To understand how film might degrade over long periods of time, scientists perform experiments on film at high temperatures and relative humidity" (Ahmad 2020). Extraposed subject: "It would be easy to assume evolution works by continuously adding features to organisms." (Guijarro-Clarke and Paps 2020).
infinitive particle (infinitive marker): noun phrase COUNTABLE GRAMMAR The word "to" used to introduce the infinitive form of lexical verbs. Examples: "I just called to say I love you" (Wonder 1984). It is also used in the complex infinitive markers "in order to" and "so as to", introducing adverbial clauses of purpose, and in phrases such as "have to", "used to" and "ought to". "We have to concentrate in order to learn how to read music, and we have to try and memorise which piano key plays which note" (Power 2021).

See (Bloor and Bloor 2004). You can see many examples of nominalization on the suffix page.
nominal ellipsis: noun phrase UNCOUNTABLE COHESIVE DEVICES The substitution of the head of a noun phrase by nothing. The missing noun phrase can always be recovered from the preceding text - either in the same sentence or an earlier one.

"Why do we prefer one hand over another?" (Barton and Todorovic 2021). The word "another" is incomplete. Another what? Obviously "another hand" "hand" is the head of a noun phrase in the first part of the sentence so we can recover it from there in the second part. This is nominal ellipsis.

"When one domino gets knocked down, it knocks down another and another" (Taylor 2020). The word "another" is obviously part of a noun phrase "another domino" but with a missing headword which we can recover from the first part of ther sentence.

"The bird at the point of the V, in the front of the flock, gets no advantage from drafting. It is working much harder than the others. When it gets too tired, it drops back and another takes the lead " (Langen 2020). The word "another" is part of a noun phrase "another bird" but with a missing headword. To find this headword we have to trace the pronouns "it" back two sentences to the "The bird at the point of the V".

"First, we must make keys secret by making a very large number of possible keys, so that the right one is hard to guess or build. It’s the same for passwords" (Craver 2022). The word "the same" substitutes for "we must make keys secret by making a very large number of possible keys, so that the right one is hard to guess or build" - almost all of the previous sentence. The first sentence refers to physical keys and the second refers to software keys.

"For example, many of the horizontally transferred genes detected in grasses offer disease resistance, stress tolerance and increased energy production." (Pereira, Dunning, and Raimondeau 2023) (1. -ed participial, attributive, ungradable; 2. -ed participial, attributive, gradable)

"But we still don’t know how genes are moving between distantly related species. " (Pereira, Dunning, and Raimondeau 2023) (-ed participial, attributive, ungradable)
participle: noun COUNTABLE GRAMMAR A non-finite verb form used as an adjective and also to form the perfect and progressive aspect and the passive voice. The present participle (-ing participle) is formed by adding -ing to the verb root (challenging task, distracting noise). The past participle (-ed participle) is formed by adding -ed to the verb root, except in the case of irregular verbs (selected text, broken window). See more about participles used as noun premodifiers on the noun premodification page.
participle clause: noun phrase COUNTABLE GRAMMAR A clause introduce by a participle (present or past). They may function as the subject or object of a sentence and in postmodification of a noun phrase. See ed-clauses, ing-clauses, and examples on the ed-clause page and the ing-clause page.
particle: noun COUNTABLE GRAMMAR A word which normally has little or no meaning except when combined with another. The word particle is often taken to mean an adverbial particle but there are other particles such as the negator 'not' and the infinitive marker 'to' which have little meaning when taken out of context. An adverbial particle is not the same as a preposition. A preposition is more part of a prepositional phrase whereas a particle is more connected to the verb, and the verb-particle combination often has a particular meaning which is not always obvious from a consideration of the individual words.

"Social media took off somewhat later, in the second half of the first decade of this century." (During 2022) ('took off' means 'increased sharply'; off is a particle - it belongs with the verb 'take' creating a new meaning)

"Currently, 53 World Heritage properties are on the in-danger list; others were taken off the list once concerns were addressed." (Day, Heron, and Hughes 2021) ('off' is a preposition and part of the prepositional phrase 'off the list'. )
particle shift: noun phrase COUNTABLE GRAMMAR A particle in a phrasal verb (e.g. get up, carry out, go on) may move to a position after the direct object noun phrase. This is known as a particle shift. Examples: "[Play-based learning] can also set your child up for success in the 21st century by teaching them relevant skills" (Morrissey, Rouse, and Robertson 2018). The phrasal verb is set up and the particle up has been shifted; it could be written as "[Play-based learning] can also set up your child for success...". If the direct object is a pronoun then a particle shift must be used: "Teaching kids about maths using money can set them up for financial security" (Attard 2017).
passive: adjective GRAMMAR Passive describes a verb when the subject of the sentence is the sufferer of the action rather than the performer. In the sentence, "The dog is being washed by the boy.”, "The dog” is the subject and suffers the action. "is being washed” is a verb in the passive voice. There are two types of passive constructions: the long passive where the agent is mentioned (usually with a by-phrase), and the short passive where the agent is omitted.

Long passive

"The ENIAC patent was thrown out by a judge in 1973." (Jacobson 2019) ('was thrown out' is the passive construction and 'by a judge' describes the agent; compare with the active: A judge threw out the ENIAC patent in 1973)

"The rings around Saturn were discovered by an astronomer called Galileo Galilei nearly 400 years ago." (Kuhn 2020) ('were discovered' is the passive construction and 'by an astronomer called Galileo Galilei' describes the agent; compare with the active: An astronomer called Galileo Galilei discovered the rings around Saturn nearly 400 years ago.)

Short passive

"They were asked to memorise both lists." (Noreen 2015) ('were asked' is the passive construction and no agent is mentioned; compare with the active: [Somebody] asked them to memorise both lists.)

"The last one was spotted more than 60 years ago." (Cushing 2020) ('was spotted' is the passive construction and no agent is mentioned; compare with the active: [Somebody] spotted the last one more than 60 years ago.)

There are two types of passive constructions: Finite Constructions and Non-finite Constructions
Compare with active. See the passives page and the passive examples pages.
passive: finite constructions: noun phrase COUNTABLE GRAMMAR These constructions take a finite verb (there is a subject and the verb shows tense). There are four types:

Short passive with a stative verb

"For a very long time, Saturn was thought to be the only planet in our solar system with rings." (Kuhn 2020) ('was thought' is the passive construction; 'think' is a stative verb and it is a short passive because no agent is mentioned)

"That same century, scientists identified carbon dioxide’s potential to increase global temperatures, which at the time was considered a possible benefit to the planet." (Weatherhead 2021) ('was considered' is the passive construction; 'consider' is a stative verb and it is a short passive because no agent is mentioned)

Short passive with a dynamic verb

"Everything changed when electric lighting was invented in the latter part of the 19th century." (Stevens 2015) ('was invented' is the passive construction; 'invent' is a dynamic verb and it is a short passive because no agent is mentioned)

"An enormous amount of heat was produced during those collisions, enough to melt the whole Earth." (Huang 2023) ('was produced' is the passive construction; 'produce' is a dynamic verb and it is a short passive because no agent is mentioned)

Long passives

"This would be like how the International Space Station was built: pieces were taken into space and then [were] put together by astronauts aboard the space shuttle." (Whittaker 2021) ('were taken' and '[were] put' are both passive constructions; the agent is 'astronauts')

"This is because the Himalayas were built by the collision of two large continents composed of rocks with lower than average density." (Duffy and McLaren 2021) ('were built' is the passive construction; the agent is 'the collision of two large continents composed of rocks with lower than average density')

Get passives

"For example, most adults do not get told when to go to bed at night!" (Mackey, Lee, and Wee 2021) ('get told' is the passive construction; )

"This way, authors get paid for their writing, but the publisher also profits from book sales." (Farina 2022) ('get paid' is the passive construction)

See the passives page and the passive examples pages.
passive: non-finite constructions: noun phrase COUNTABLE GRAMMAR These constructions take a non-finite verb. There are four main types:

Noun postmodifier, short passive

"In a study published last year, the participants were presented with two files that each contained a list of words."(Noreen 2015) ('published' is the passive noun postmodifier; it is a short passive because no agent is mentioned)

Noun postmodifier, long passive

"All along, cars powered by internal combustion engines – the kind most in use today – were competing with steam cars and winning the technology war." (Stewart and Yohe 2022) ('powered' is the passive noun postmodifier; it is a long passive and the agent is 'internal combustion engines')

"How to answer this question will need to be figured out by a future scientist." (Singal 2021) ('to be figured out' is the infinitive clause complement of the verb 'need' ; it is a long passive and the agent is 'a future scientist')

"The AI chatbot ChatGPT produces content that can appear to have been created by a human." (Sekhon, Ozcan, and Ozcan 2023) ('to have been created' is the infinitive clause complement of the verb 'appear' ; it is a long passive and the agent is 'a human')

"The term Global South appears to have been first used in 1969 by political activist Carl Oglesby." (Heine 2023) ('to have been [first] used' is the infinitive clause complement of the verb 'appears' ; it is a long passive and the agent is 'political activist Carl Oglesby')

Ed-clause complement of a verb

"[ ] fish may have had key features 'removed', such as the bills of billfish or fins of sharks, or whole parts missing, e.g. heads." (Proctor, O’Neill, and White 2018) ('removed' is the ed-clause complement of a verb 'may have had' ; it is a short passive because no agent id mentioned)

See more examples on the non-finite passive constructions page.

In passive constructions what was the object in the active is moved to a subject position. (This is common in academic texts.):

Active: Writers base many modern stories on older stories.

"We also know that intense emotions are associated with stronger memories and preferences" (McAndrew 2019).
Active: We also know that we associate intense emotions with stronger memories and preferences.

With a prepositional verb, the preposition belongs more to the verb than the noun; the verb and the preposition form one lexical entity, and a change in the preposition would change the whole meaning of the verb + preposition or render it meaningless.
See examples on the prepositional verbs page. See also the subject-verb-prepositional object pattern.

"Pääbo did his PhD in medical science at Uppsala University in Sweden". The following sentence is an example of the use of a primary verb as an auxiliary verb "Today most people do not get enough sleep".

Nominal clauses:

Why this happens is a bit of a mystery. (Langen 2020)

To-clauses:

To make something go twice as fast takes four times the energy. (Impey 2021)

A subject may also be a dummy, or empty subject:
It's cold today.

Note that in all the above cases the subject precedes the verb phrase. This is true for all sentences except interrogative clauses. In these cases the subject is placed after the operator:
Is chocolate delicious?

Where do they live?

The only exception to this rule is if the subject is a wh-word:
Who is paying for this?

Subjects may also be classified by their semantic roles: see agent, instrument, external causer, recipient, eventive, local, and temporal, See also object.
subject: noun COUNTABLE An area of study in a school, college or university.
subject complement: noun phrase COUNTABLE GRAMMAR A subject complement is also known as a subject predicative. The complement (or predicative) has the same referent as the subject and is connected to it by a copular verb. See also the subject - verb - subject predicative page.
subject predicative: noun phrase COUNTABLE GRAMMAR A subject predicative complements a subject. It may be a noun phrase, an adjective phrase, or an ing-clause. A subject predicative has the same reference as the subject (the subject and the subject predicative refer to the same thing), or it provides information about the subject. Subject predicatives only follow copular verbs. They are sometimes referred to as subject complements.
Example 1 - Noun phrase
In the sentence "Pizza is one of the world’s most popular foods.", "Pizza" is the subject, "is" is the copula, and "one of the world’s most popular foods" is the subject predicative. "Pizza" and "one of the world’s most popular foods" have the same referent. They refer to the same thing.

Example 2 - Adjective phrase
In the sentence "These wings then gradually became more powerful and covered in feathers and were eventually used to fly." (Wills 2020), "These wings" is the subject, "became" is the copula, and "more powerful and covered in feathers" is the subject predicative. "more powerful and covered in feathers" is an adjective phrase describing what eventually happened to the subject "These wings".

Example 3 - Ing-clause
In the sentence "The problem is getting a truly optimal source for data." , "The problem" is the subject, "is" is the copula, and "getting a truly optimal source for data" is the subject predicative. "getting a truly optimal source for data" is an ing-clause phrase identifying "The problem".
See also object predicative.
subject-verb agreement (concord): noun phrase GRAMMAR Subject-verb agreement (or concord) refers to the fact that, apart from the verb to be, lexical verbs only change their form in the present tense when the subject is in the third person singular (he, she, it, or a third person noun phrase).
subject – verb (SV) pattern: noun phrase COUNTABLE CLAUSE PATTERN An SV (subject – verb phrase) clause contains a subject and an intransitive verb (also know as a one-place verb). There are not many purely intransitive verbs and even those which are intransitive may take an optional adverbial.

Examples (subject verb):

"As temperatures rise and sea ice disappears, emperors will face new challenges" (Younger 2019). (SV, no adverbial. Note that "emperors" refers to emperor penguins)

"In Australia, giant kangaroos and wombats disappeared 46,000 years ago" (Longrich 2020). (SV, plus adverbial - "46,000 years ago".)

"Until 1916 there had been many theories to try and explain what gravity was and why it exists" (Webb 2023). (SV, no adverbial.)

"Words exist because of meaning." (Davis 2023). (SV, plus adverbial - "because of meaning".)

Although the above examples show the structure with and without adverbials, most intransitive verbs are used with adverbials of one kind or another.
Common verbs used in this pattern are: appear, arrive, begin, continue, die, disappear, emerge, exist, fall, float, go, happen, laugh, listen, live, occur, rise, sit, sleep, smile, start, stop, think, vanish, wait.
See more examples on the subject – verb pattern page.
subject – verb – adverbial (SVA) pattern: noun phrase COUNTABLE CLAUSE PATTERN An SVA (subject – verb phrase – adverbial) clause contains a subject, an intransitive verb, and an obligatory adverbial. The adverbial is obligatory because without it either the sentence does not make sense, or the sentence has another (possibly implausible) meaning.

"This means that one day on Earth lasts 24 hours" (Loon 2022). (Without the adverbial "24 hours", the sentence makes no sense.)

"When people sleep we close our eyes and lie motionless for a long time" (Brown 2019). (Without the adverbial "motionless for a long time", the sentence has a different, improbable, meaning.)

"We’re all different right? Some people look different. And some people think differently" (Simner 2021). (SVA x2: without the adverbials the sentences have a different meaning.)

See more examples on the subject – verb – adverbial pattern page.
subject – verb – complement clause(SV + CC) pattern: noun phrase COUNTABLE CLAUSE PATTERN An SV + CC (subject – verb – complement clause) clause contains a subject, a monotransitive verb, and a complement clause. The complement clause can be a that clause, a wh-clause, an infinitive clause, or an ing-clause. Sometimes the complement may be interpreted as the object in an (SVO_d) pattern.

SV + that-clause complement

"Scientists now know that it takes thousands of species to support human life" (Langen 2022).

"Scientists think that genes may play a role, but no one knows exactly how at this point" (Fabiano 2021).

"You have probably eaten some food that went bad, and you might find that you hate that food now" (Lemons, Kenney, and Lin 2020)

"Herodotus claimed that Africa was surrounded almost entirely by sea" (Dorrian and Whittaker 2020).

"Previous studies showed that chimpanzees have excellent short-term and long-term memory abilities" (Völter 2019).

"But Einstein suggested that gravity was the bending of something called space-time" (Webb 2023).

SV + wh-clause complement

"This explains why we can look similar to our parents" (Atkin-Smith and Poon 2020).

"But it takes a lot of energy for your brain to see what’s going on around you, based on the messages it gets from your eyes." (Nikolova 2019).

"You might wonder what a normal amount of sleep is or if you are getting enough sleep" (Krigolson 2023).

"Most parents can begin to tell which hand their kid prefers by around two years of age" (Barton and Todorovic 2021).

"To be able to start answering the question, we need to understand what mosquitoes are" (Oliver 2022).

SV + to-clause complement

tone: noun UNCOUNTABLE The stance or emotional charge of the speaker or writer. In speaking, tone is signalled both by the quality of the speaker’s voice and the choice of words; in writing tone is carried only by writer’s choice of words and perhaps grammatical structures. In social media exchanges it may be signalled by the use of capital letters, exaggerated use of punctuation and the use of non lexical signs such as emojis. None of this has any place in academic communication, which should always be measured and straightforward.

valency: noun COUNTABLE GRAMMAR An indication of the number of grammatical items to which a a verb may connect.

a one-place verb connects only to a subject (therefore intransitive)

a two-place verb connects to a subject and another element (e.g. a direct object, therefore transitive)

a three-place verb connects to a subject and another two elements, (e.g. a direct object and an indirect object, therefore ditransitive)

Verbs may have more than one valency, depending on their use.
validity: noun UNCOUNTABLE ASSESSMENT The extent to which a test measures what it is designed to measure. See also construct validity, content validity, predictive validity, face validity.
verb: noun COUNTABLE GRAMMAR A word used to describe actions, states or events - verb phrases are essential parts of almost all English clauses.
verb classification: lexical - multi-word verbs: noun phrase UNCOUNTABLE Verbs may be divided into the two categories of lexical verbs and multi-word verbs. Lexical verbs (full verbs) are single word verbs. Multi-word verbs include phrasal verbs, prepositional verbs, and phrasal-prepositional verbs. See the multi-word verbs page.
verb classification: main categories: noun phrase UNCOUNTABLE The main categories of verbs are lexical verbs, primary verbs, and modal verbs. Verbs are also classified by their roles in the verb phrase - as the main verb or as an auxiliary verb. Lexical verbs (go, say, find ...) only function as main verbs. Primary verbs (there are only three: be, have, do) function as both main verbs and auxiliary verbs. Modal verbs (can, must, might ..) only function as auxiliary verbs.
verb classification: semantic domains: noun phrase SEMANTICS Lexical verbs are sometimes classified semantically - by their meaning. Many verbs are used with more than one meaning, so this classification is not a rigid one; some verbs may fall into more than one category. There are seven broad categories: activity verbs, aspectual verbs, causative verbs, communication verbs, existence verbs, mental verbs, occurrence verbs.
verb classification: valency patterns: noun phrase UNCOUNTABLE Verbs may be categorised by their valency (an indication of the number of grammatical items to which a verb may connect). The main valency patterns are one-place (combining only with a subject), two-place (combining with a subject and another element), and three-place (combining only with a subject two other elements).
verb phrase: noun phrase COUNTABLE GRAMMAR Part of a sentence containing one lexical verb or primary verb as the head of the phrase and possibly as many as four auxiliary verbs, as well as the word not. A verb phrase may consist of just one lexical or primary verb: "Most foods contain at least some sugar". A verb phrase may also have one or more auxiliary verbs: "Historical films may be decaying much faster than we thought". may and be are auxiliary verbs in this sentence.
verbal ellipsis: noun phrase UNCOUNTABLE COHESIVE DEVICES The omission of a lexical verb from a verb phrase. The verb is recoverable from the previous text.

"That computer would pass it along in the right direction as soon as it could." (Martin 2023). The word "could" is an incomplete verb phrase. The lexical verb is missing. But we can recover it from the verb phrase in the first part of the sentence: "would pass". The complete verb phrase in the second part would be "could pass (it)". This is verbal ellipsis.

See also the ellipsis page.
verbal substitution: noun phrase UNCOUNTABLE COHESIVE DEVICES The substitution of a lexical verb by a form of the lexical verb "do". "Your brain remembers how to drive a car because it’s something you’ve done many times before" (Cleo 2023). "done" substitutes for the verb "drive" (you have driven a car many times before). See more on the substitution page.
voice: noun UNCOUNTABLE GRAMMAR The relationship between a verb and any associated noun phrase, and the resulting emphasis caused by this. This usually means the distinction between the active voice and the passive voice. The passive voice is often used when the writer does not wish or is not able to name the agent. For example: "A lot of claims have been made about the benefits of tai chi." (Nyman 2020). In this case it may not be possible or easy to name those who made the claims or there may be too many to name. So the passive voice is more convenient.
volume: noun COUNTABLE A set of issues of a journal.
volume: noun COUNTABLE One book in a set.
washback: noun UNCOUNTABLE ASSESSMENT The effect a test or examination has on a curriculum or on teaching methodology. Washback may be positive or negative depending on the quality of the test and how it is perceived by teachers and students.
wh-clause: noun COUNTABLE GRAMMAR A clause which begins with a wh-word (who, what, which, where, when, why, how, whether, whatever, whichever ) and acts either as a dependent interrogative clause or a nominal relative clause. Examples:
Dependent Interrogative Clauses

"How do you know whether your school is a “good” one?" (Riddle 2023)

"Have you ever wondered what it would be like to travel to outer space – and then keep going?" (Singal 2021)

Nominal Relative Clauses

"The trail of digital data you leave – both online and offline – is what makes you especially valuable." (Ashley 2019)

"The different colours blend into each other, and it is difficult to tell where one colour ends and another begins." (Rawlings 2022)

"What the equation seems to say is that energy equals mass times some number." (Baron 2021)
wh-cleft: noun COUNTABLE GRAMMAR A means of bringing information into quick focus in a sentence by using a clause containing the point of focus introduced by a "wh word " + a form of the verb "be" + the focused information (usually a phrase, an infinitive clause or a finite nominal clause). For example: "What we have added was the discovery that AI can help find these heat-resilient corals" (Elagali et al. 2022). See also it-cleft.
wh-word: noun COUNTABLE GRAMMAR Wh-words include who, what, which, where, when, why, whose, how, whether, whatever, whichever, and that. Examples: wh-words act as:

Interrogative Clause Markers

"More recently it has spawned the system of GPS global positioning satellites that can give us a readout on our locations wherever we are" (Mowery 2019).
word class: noun phrase COUNTABLE GRAMMAR Words are divided into three main classes: lexical words, function words and inserts.

Lexical words are members of open classes; the four main classes are nouns, verbs, adjectives and adverbs;

Function words are members of closed classes. Their function is to indicate relationships between words, phrases or clauses, or to show how words phrases or clauses should be understood. Examples of function words are; determiners, prepositions, coordinators, subordinators, auxiliary verbs, wh-words;

Inserts are mainly used in spoken language and there are various categories such as interjections, greetings, discourse markers, expletives and so on.
wordiness: noun UNCOUNTABLE STYLE The use of more words than necessary. Adjective: wordy.
