故

• ピンイン: gù
• 漢字の分解: 故 = 古 (old, ancient) + 攴 (hand striking) — old event or cause; hence 'reason,' 'therefore,' 'on purpose,' and 'old/former'

意味

（文語）ゆえに；（〜に）わざと

This single character carries multiple meanings rooted in classical Chinese: (1) 'therefore, hence' in formal prose; (2) 'on purpose, deliberately' (as in 故意); (3) 'old, former' (故乡 = hometown; 故人 = old friend); (4) 'cause, reason' (无故 = without cause). In modern usage, the 'therefore' and 'deliberately' senses are most active in formal writing and idioms.
