Notional grammars define adjectives as words that modify or describe nouns. An adjective phrase is a phrase that consists of an adjective functioning as the head of the phrase plus any modifiers or complements.
In grammar, an object complement is a word, phrase, or clause that directly follows and describes or completes the direct object within the predicate of a clause. Adjectives and adjective phrases often function as object complements in English. Examples of adjectives and adjective phrases as noun phrase modifiers include the following:
- The mayor declared the new park open. (adjective)
- We painted the roses red. (adjective)
- The citizens elected Benjamin Williams mayor. (adjective)
- He found the book questionable. (adjective)
- I consider studying grammar quite entertaining. (adjective phrase)
- Why did you color your hair blue and black? (adjective phrase)
- I once painted my bedroom walls bright pink. (adjective phrase)
- The clown got the children overly excited. (adjective phrase)
