I-adjectives in Japanese grammar are adjectives that describe qualities or states of being and usually end in “~i” (い). They are used to describe nouns, and their conjugation for tense and negation is done by changing the ending. Examples of I-adjectives include: たかい (high/tall), おもしろい (interesting), and さむい (cold). These adjectives conjugate differently than na-adjectives, which is another category of adjectives in Japanese. In this exercise, you will practice using I-adjectives in various grammatical situations.
