Signal Phrases

How to use signal phrases

What are signal phrases?

Signal phrases (also known as reporting phrases) introduce the ideas you want to use from external sources. These ideas can be the actual words which you take from the original text (a quotation) or a restatement of these ideas in your own words (a paraphrase). Signal words can be very simple (states that …, writes that …).

Signal phrases are very important because they allow you to hint at your own stance or interpretation of what another writer stated. It is important to understand that it is you who are indicating this when you are quoting or paraphrasing; the original author didn't write "I declare that", "I imply that", etc. It is you who are quoting or paraphrasing and it is you who are saying that this is a declaration, a hypothesis, an implication an acknowledgement, a denial and so on. They can also indicate more explicitly your opinion about the writer’s ideas (argues convincingly that …). You, at least, were convinced by the writer; other readers might be less persuaded.

Here is an example:

Freebody and Anderson suggest that "cohesion, in the specific sense of linguistic ties, simply is not very important in reading" (1983 p91).

"suggest that" is a typical signal phrase. A signal phrase introduces an idea (or a proposition, argument, rebuttal etc.) which the writer found during her research. In this case we have a quotation. These are the exact words found in that particular article in that journal indicated in the citation and which you can find in the bibliography.

The word "suggest" was chosen by the writer who found this quotation during her research. She could have used other words (claim, state, argue ....). But you should choose your signal words carefully; they can give clues about the information presented in the quotation, information about the writer's stance, and clues to your attitude to the information in the quotation.

We could also rewrite this in the form of a paraphrase. For example: Freebody and Anderson (1983 p91) suggest that, as far as linguistic ties are concerned, cohesion is not of much importance in reading.

The signal phrase makes it clear that the comment about cohesion in reading belongs to the writers Freebody and Anderson.

There are many verbs which can be used in signal phrases but there is a limited set in common use. These are the ones you are most likely to see (or need to use):

  • Acknowledge : to accept the truth or value of something. "A survey we conducted with Ohio residents [ ] demonstrated that more than 82% of Ohioans acknowledged the intrinsic value of wildlife." (Bruskotter, Vucetich, and Nelson 2015);
  • Add: to give further support or evidence to something already mentioned. "This report added that the trade threatened South Africa’s global standing as a leader in the conservation of wildlife and as a country and destination with iconic wild lions." (Elwin, Green, and D’Cruze 2024);
  • Admit: to concede (perhaps unwillingly) that something is true. "Writer Jennifer Lepp admits that as she increasingly relied on Sudowrite, the resulting text “didn’t feel like mine anymore. It was very uncomfortable to look back over what I wrote and not really feel connected to the words or ideas.”" (Baron 2023);
  • Affirm: to make a strong statement about the truth of something. "In late November 2018, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) affirmed that all these wildlife species are at risk of disappearing from Canada." (Mooers and Reynolds 2019) ;

  • Argue: to give reasons and evidence to support a point of view. "Aristarchus of Samos (310BC to 230BC) argued that the Sun was the “central fire” of the cosmos and he placed all of the then known planets in their correct order of distance around it." (Dorrian and Whittaker 2020);
  • Assert: to strongly state that something is true. "In her book, “Living Oil: Petroleum Culture in the American Century,” literature scholar Stephanie LeMenager asserts that 20th-century culture – novels, poetry, films, photography and television – generated a mythology of “petro-utopia.”" (Allison and Miller 2019);
  • Claim: to make a statement of belief (possibly without evidence) which others might refute. "In an innovative paper published in 1938, he claimed there was an “increase in mean temperature, due to the artificial production of carbon dioxide.”" (Dee 2022);
  • Comment: to give an opinion or extra information about a topic or claim. "Many people have quoted author Flannery O’Connor’s comment that “I write because I don’t know what I think until I read what I say.”" (Baron 2023) [Here, 'comment' is used as a noun.];
  • Concede: to agree that a statement expressed by someone else is true, or give up a previously held belief. "Rollier conceded that one could sunbathe anywhere and obtain some benefit." (Scaglia 2020);
  • Conclude: to give a final statement or remark based on the results of an investigation. "A 2008 meta-analysis concluded periodontitis had an effect on general health but issues of both the criteria for periodontal disease and confounding (diseases having the same risk factors as periodontal disease) need to be resolved." (Roberts-Thomson 2012);
  • Confirm: to give an additional or final statement about the truth of something. "Epidemiological studies have confirmed that patients with diabetes (both type 1 and type 2) are more susceptible to periodontal disease." (Roberts-Thomson 2012);
  • Declare: to publicly state a position. "As a result, some scholars have declared that online shaming is a “moral wrong and social ill (Forestal 2024);

  • Find: to show the results of an experiment, survey or inquiry. "A recent survey found that 62% of university students were listening to music while studying or doing homework." (Vasilev 2019);

"And in 2018, a report predicted that without major reductions in greenhouse gas emissions, all 29 World Heritage coral reefs, including the Great Barrier Reef, will cease to be “functioning ecosystems by the end of the century”." (Day, Heron, and Hughes 2021);
  • Propose: to suggest some thing (an idea, solution to a problem, topic for discussion, etc.). "This idea that individuals prioritise where information is located has led some researchers to propose that digital devices and the internet have become a form of transactive memory." (Noreen 2015);

Other ways of signalling a quote or paraphrase

The list above shows common verbs used in signal phrases but there are other ways of signalling that you are quoting information from another source. A favourite among students is "according to". It can be used almost anywhere and its tone is neutral. But, unfortunately, that means you can't signal your anything about the type of information contained in the quote (whether it is a claim, denial, refutation, etc.), and you can't (without adding a dependent clause) hint at your own stance. Also, a student paper peppered with this signal phrase indicates that writer has limited flexibility in the use of these structures.

Furthermore, in real texts it is mainly used to point to information from a report, rather than a named author. It is most often found in phrases such as:

  • according to the report, ...
  • according to a [new, recent] study, ...
  • according to a [study, report] [by, in], ...
  • according to an article in, ...
  • according to a recent survey, ...
  • according to a [study, report] published in, ...
  • according to data from, ...

Here are a few examples from real texts

  • "According to this account, individuals can collectively store and distribute information using a shared store of knowledge." ("this account" refers to a link in the previous paragraph) (Noreen 2015)
  • "In Australia, it’s also now five days shorter than the 1950–1969 period, according to Australia Institute research." (clicking the 'research' link takes you to the original article. This is a common way of crediting sources in journalistic texts.) (Noreen 2015)
  • "According to its discoverers, Danuvius guggenmosi combines some human-like features with others that look like those of living chimpanzees." (This is a paraphrase and we can only find the discoverers by following a previous link in the text) (Winder and Shaw 2019)
  • "But according to culinary scientists, they contain flavor compounds that taste even better when eaten together." (We don't know who these culinary scientists are without clicking the link to the article. This is a common way of crediting sources in journalistic texts.) (Miller 2019)

You can see how signal phrases are used in real texts, do a practice exercise, and test your understanding of the terminology of citing.
