改訂
かいてい · kaitei · JLPT N1 · noun
revision
📝 改 = change + 訂 = correct: a revision changes and corrects a text
Both kanji mean to alter or fix something, like marking up a draft. Use it for a new edition of a book or a revised plan.
改 — 己 (self) + 攴/攵 (action/strike)
改 is a compound of 己 'self' and 攵 (the action radical, originally a hand holding a stick). The image is of striking or applying force to oneself or one's situation, suggesting reform or correction. From this came the modern meaning 'to change, alter, correct'.
