テスト前の一夜漬け

• 読み: テストまえのいちやづけ
• ローマ字: tesuto mae no ichiyazuke
• 漢字の分解: テスト (test, from English) + 前 (before) + の (possessive) + 一 (one) + 夜 (night) + 漬け (pickling) → overnight cramming before a test
• 発音: /te.sɯ.to ma.e no i.tɕi.ja.zɯ.ke/

意味

Cramming the night before an exam; an all-night last-minute study session.

一夜漬け literally means 'overnight pickling' — just as vegetables need time to pickle properly, knowledge needs time to absorb, but you're trying to do it in one night. It's a universal student experience in Japan and usually spoken of with a mix of guilt and camaraderie. The phrase テスト前の一夜漬け specifically ties it to exam periods, but 一夜漬け alone is commonly understood.

例文

1. 毎回テスト前の一夜漬けで乗り切ってるけど、そろそろ限界かも。
2. 一夜漬けで覚えたことって試験終わったら全部忘れるよね。
3. 今夜は一夜漬けだから、コンビニでエナドリ買ってきた。
