それな

• 読み: それな
• ローマ字: sore na
• 発音: /so.ɾe.na/

意味

That's so true, exactly, big agree — a quick affirmation showing strong agreement with what someone just said.

それな is the ultimate agreement word in casual Japanese conversation. It is essentially 'that' (それ) + the confirmatory particle な, creating a punchy 'exactly that!' response. It requires no elaboration — just それな on its own conveys total agreement. It is the conversational equivalent of vigorously nodding. Overuse can sound dismissive, as if you are not really listening.

例文

1. 「月曜の朝って一番つらいよね」「それな」
2. 「このカフェの雰囲気最高じゃない？」「それなー」
3. 「もう少し給料上がってほしい」「ほんとそれな」
