Traditional grammars define adjectives as “words that describe nouns.”
In grammar, an adjective phrase consists of an adjective plus any modifiers or complements. Adjectives always function as the head of an adjective phrase. Examples of adjectives as adjective phrase heads include the following:
- super special
- exceedingly loud
- afraid to fly
- happy for the winner
- positive that grammar is fun
