ないわ

• 読み: ないわ
• ローマ字: nai wa
• 発音: /na.i.wa/

意味

No way, absolutely not, or hard pass — a blunt dismissal expressing that something is completely unacceptable.

ないわ (from ない + sentence-final particle わ) is a casual but emphatic way of rejecting something. It declares that whatever was proposed, shown, or said is so far below acceptable standards that it does not even merit consideration. It is commonly used to reject fashion choices, relationship behaviours, ideas, and anything else deemed unworthy. The trailing わ adds emotional emphasis and slight femininity, though male speakers use it too.

例文

1. あの服で来るの？ないわ〜。
2. ないわって思ったけど、口には出さなかった。
3. ドタキャンしといて謝罪なし？ないわ。
