形容詞(けいようし) is a Japanese grammar term meaning "adjective." In traditional Japanese grammar (国文法(こくぶんぽう)), it specifically refers to い-adjectives — words like (たか)い, (おお)きい, and (うつく)しい that end in い and conjugate.

IMPORTANT DISTINCTION:

  • 形容詞(けいようし): い-adjective (conjugates: (たか)い → (たか)くない)
  • 形容動詞(けいようどうし): な-adjective (uses だ/な: (しず)かだ, (しず)かな)

In school grammar and textbooks, these are treated as separate parts of speech.
