According to traditional grammars, 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, a subject complement is a word, phrase, or clause that follows a copular, or linking, verb and describes the subject of a clause. Adjectives and adjective phrases often function as subject complements in English. An adjective that performs the grammatical function of subject complement is also called a predicate adjective. Examples of adjectives and adjective phrases as subject complements include the following:
- Roses are red. (adjective)
- Violets are blue. (adjective)
- The patient appears ill. (adjective)
- My soup tastes peppery. (adjective)
- Those children are quite rowdy. (adjective phrase)
- That hand lotion is too sticky. (adjective phrase)
- Some men are fond of football. (adjective phrase)
- Your daughter seems much too shy to try out. (adjective phrase)
