いやいやいや

• 読み: いやいやいや
• ローマ字: iya iya iya
• 発音: /i.ja i.ja i.ja/

意味

No no no — a rapid denial or expression of disbelief, the classic tsukkomi response to something outrageous or absurd.

Rooted in Japanese comedy's boke-tsukkomi dynamic, いやいやいや is the instinctive response of the straight man (tsukkomi) when the funny man (boke) says something ridiculous. The triple repetition conveys urgency — one いや would be a calm disagreement, but three stacked together signals 'hold on, what you just said is absolutely insane.' It has transcended comedy stages and become a universal conversational tool for expressing incredulous denial.

例文

1. いやいやいや、それ絶対嘘でしょ？本気で言ってる？
2. 「明日までにこの仕事全部やって」「いやいやいや、無理に決まってるじゃん」
3. いやいやいや、なんでそうなるの？話飛びすぎでしょ。

正しい言い方

• いやいやいや、さすがにそれはおかしいでしょ。 (No no no, that's obviously wrong.)
• いやいやいや、聞いてなかったの？真逆だよ。 (No no no, weren't you listening? It's the complete opposite.)

避ける言い方

• フォーマルな場で「いやいやいや」と連発するのはNG (Rapid-firing いやいやいや in formal settings is inappropriate — it sounds like a comedy routine)

よくある間違い

• Using only one いや when trying to express strong disbelief — the repetition is what carries the comedic or emphatic force
• Mistaking it for genuine anger; いやいやいや is usually light-hearted or exasperated, not hostile
