先輩

• 読み: せんぱい
• ローマ字: senpai
• 漢字の分解: 先 (ahead/previous) + 輩 (companion/colleague) → one who came before; senior
• 発音: /seɴ.pa.i/

意味

A senior student, upperclassman, or someone more experienced in a shared context like school, work, or a club.

先輩 is one of the most fundamental social relationship terms in Japanese culture. In schools and universities, it refers to students in higher grades. The 先輩/後輩 dynamic dictates behavior — 後輩 are expected to show respect, use polite language, and defer to 先輩. This hierarchy extends to workplaces and any shared organization. In recent pop culture, 'senpai' has also become known globally through the 'notice me senpai' meme.
