萎える

• 読み: なえる
• ローマ字: naeru
• 漢字の分解: 萎 (na): wilt, wither, droop
• 発音: /na.e.ɾɯ/

意味

To lose motivation, feel deflated, or have one's excitement killed — describes the sudden draining of enthusiasm.

Originally meaning 'to wilt' (like a plant), 萎える in slang describes the feeling when your energy or excitement suddenly drains away — a buzzkill moment. It can be triggered by bad news, awkward situations, or anything that kills the mood. It is especially common among younger speakers and on social media to describe disappointment or deflation.

例文

1. 楽しみにしてたイベントが中止で萎えた。
2. せっかく早起きしたのに電車が止まってて萎える。
3. あの一言で完全に萎えたわ。
