Other noun modifiers

In many languages, including English, it is possible for nouns to modify other nouns. Unlike adjectives, nouns acting as modifiers (called attributive nouns or noun adjuncts) are not predicative; a red car is red, but a car park is not "car". In English, the modifier often indicates origin ("Virginia reel"), purpose ("work clothes"), or semantic patient ("man eater"). However, it can generally indicate almost any semantic relationship. It is also common for adjectives to be derived from nouns, as in English boyish, birdlike, behavioral, famous, manly, angelic, and so on.

Many languages have special verbal forms called participles that can act as noun modifiers. In some languages, including English, there is a strong tendency for participles to evolve into adjectives. English examples of this include relieved (the past participle of the verb relieve, used as an adjective in sentences such as "I am so relieved to see you") and going (the present participle of the verb go, used as an adjective in sentences such as "Ten dollars per hour is the going rate").

Other constructs that often modify nouns include prepositional phrases (as in English "a rebel without a cause"), relative clauses (as in English "the man who wasn't there"), other adjective clauses (as in English "the bookstore where he worked"), and infinitive phrases (as in English "pizza to die for").

Relatedly, many nouns take complements such as content clauses (as in English "the idea that I would do that"); these are not commonly considered modifiers, however.
