意味

Blue; azure. Also used for green in certain traditional contexts like traffic lights.

An i-adjective for the color blue. In traditional Japanese color classification, 青 covered both blue and green — this is why green traffic lights are called 青信号 (blue signal) and unripe fruit is 青い. Modern Japanese distinguishes blue (青い) from green (緑), but the overlap persists in set expressions. The noun form is 青 (ao). Conjugates regularly: 青くない, 青かった.
