Nouns are sometimes post-modified with a to-clause. These are non-finite clauses, usually without a subject.
The to-clause gives more information about the headword. Often, the main clause containing the headword would have little meaning without the to-clause.
The noun "way" is one of the commonest headwords post-modified with a to-clause.
To-clauses often contain other nouns which are postmodified in various ways. In this sentence we have three nouns which are modified by prepositional phrases.
To-clauses often contain other nouns which are postmodified in various ways. In this sentence we have two nouns which are modified by prepositional phrases and a relative clause.
In this sentence the head noun (potential) is effectively followed by two to-clauses (to reduce falls, and [to] sustain a good quality of life ...). Again there are also two nouns modified by prepositional phrases
In this example the to-clause is followed by a wh-clause.
Another example with "way", plus two prepositional phrases.
Nouns relating to location (e.g. space, place) are also fairly common headwords followed by a to-clause.
"power", like "potential", is also a fairly common headword followed by a to-clause.
The headword itself may often be premodified in various ways, in this case by an adverb modified adjective, so that the headword may be a head noun phrase of a few words.
The words "ability" and "inability" are also not uncommon headwords to to-clauses.
Two more examples with "way" as the headword.
"time" along with "place" and "way" are probably the commonest headwords to be modified by to-clauses.
