Quick answer

An adjective is a word that describes or modifies a noun or pronoun, telling you what kind, which one or how many. In “a tall, old tree,” tall and old are adjectives describing tree.

Comparing with adjectives

Adjectives change form to compare things:

BaseComparative (two things)Superlative (three or more)
talltallertallest
happyhappierhappiest
beautifulmore beautifulmost beautiful
goodbetterbest
badworseworst

Short adjectives usually add -er and -est; longer ones use more and most.

The order of adjectives

When you stack several adjectives, English speakers follow an order most never consciously learned:

  1. Opinion (lovely, ugly)
  2. Size (big, tiny)
  3. Age (old, new)
  4. Shape (round, square)
  5. Color (blue, green)
  6. Origin (Italian, Japanese)
  7. Material (wooden, metal)
  8. Purpose (sleeping bag, running shoes)

That’s why “a beautiful big old house” sounds natural, but “an old big beautiful house” sounds odd.

Adjective or adverb?

Adjectives describe nouns; adverbs describe verbs, adjectives or other adverbs, and often end in -ly:

  • She’s a quick runner. (adjective, describes runner)
  • She runs quickly. (adverb, describes runs)

Adjectives make descriptions vivid, and so do figures of speech. Here’s what a metaphor is. For the action words in a sentence, see what a verb is.
