针锋相对
zhēn fēng xiāng duì · HSK 7
tit for tat
⚔️ 针锋 = needle-point + spear-point; 相对 = facing each other — two sharp tips aimed point-to-point
Literally needlepoint against spearpoint. Two opponents meet each blow with an equally sharp counter, giving no ground — tit for tat, measure for measure.
针 — metal radical 钅 + 十 (ten, phonetic)
针 means 'needle.' The metal radical 钅 (simplified from 金) shows the needle is made of metal, while 十 originally hinted at the sound. The traditional form 針 uses 咸-like phonetic 咸→ actually 十 served as a simplified phonetic. Over time it came to mean needle, pin, or injection.
对 — 又 (hand) + 寸 (measure/rule)
Originally depicted a hand (又) holding or responding to something, with 寸 added as a phonetic-semantic element suggesting measured action. The traditional form 對 showed a hand presenting an object in reply, giving the core sense of 'to answer' or 'face toward.' Modern meanings like 'correct' and 'pair' grew from this idea of matching response.
