モヤモヤ

• 読み: モヤモヤ
• ローマ字: moya moya
• 発音: /mo.ja.mo.ja/

意味

A hazy, unsettled feeling — vague frustration, unease, or foggy confusion that you can't quite put into words.

モヤモヤ perfectly describes that nebulous feeling of something being not quite right but you can't pinpoint why. It's the emotional fog after an argument that wasn't fully resolved, the unease about a decision you're not sure about, or the frustration of not being able to articulate what's bothering you. The word captures the mental equivalent of actual moya (fog/haze) — something obscuring clarity. It's the opposite of スッキリ.

例文

1. なんかモヤモヤするんだけど、理由がわからない。
2. あの話し合い、モヤモヤが残ったままだな。
3. モヤモヤしてる時は散歩するとスッキリするよ。
