単位

• 読み: たんい
• ローマ字: tan'i
• 漢字の分解: 単 (single/simple) + 位 (unit/rank) → unit of academic credit
• 発音: /taɴ.i/

意味

Course credits needed to graduate from university; the basic unit of academic progress.

単位 is the core currency of university life in Japan. Students need to accumulate a required number of credits (typically 124 for a bachelor's degree) by passing courses. The phrase 単位が足りない (not enough credits) strikes fear into every student, and 単位 is central to discussions about course selection, graduation requirements, and whether someone is on track. '楽単' (easy credits) are highly sought-after courses.

例文

1. 今学期あと2単位取れば卒業できるのに、やばいかも。
2. 楽単の授業ばっかり取ってたら専門知識全然つかなかった。
3. 単位落としたら4年で卒業できなくなるから必死だよ。
