歯がゆい

• 読み: はがゆい
• ローマ字: hagayui
• 漢字の分解: 歯 (shi/ha) — tooth; がゆい — itchy (colloquial adjective)
• 発音: /hɑgajɯi/

意味

Frustrating; irritating; tantalising. Describes the feeling of watching something go wrong when you are powerless to intervene, or of being unable to express yourself properly.

An i-adjective expressing a particular shade of frustration — not anger directed outward, but an internal sense of helplessness or inadequacy. Common in situations where talent goes unrewarded, communication fails, or injustice goes unchallenged. Distinct from 腹立たしい, which implies outward anger.

例文

1. 実力があるのに結果が出ない選手を見ると、歯がゆい思いがする。
2. 言いたいことがうまく言葉にならなくて歯がゆかった。
3. 不条理な制度に対して何もできない自分が歯がゆい。

起源と歴史

Literally 歯 (tooth) combined with がゆい (itchy). The image is vivid: a frustration so close you can nearly grasp it yet cannot — like an unreachable itch on your teeth. The expression has appeared in Japanese since at least the Edo period.
