残忍
cán rěn · HSK 7
cruel
🗡️ cán rěn sounds like CAN'T RUN — merciless, no escape
残 means damage/remains, 忍 means endure/bear. Together: so damaged you can barely endure it — ruthless cruelty. The sound cán rěn echoes can't run, as if the victim has no way out.
残 — 歹 (bones/death) + 戔 (small/cut, phonetic)
A semantic-phonetic compound: 歹 (bare bones, death) gives the meaning of harm or ruin, while 戔 (two 戈 spears, suggesting cutting) supplies the sound. Originally meant to injure or destroy, later extended to 'remnant, leftover' — what remains after damage.
忍 — blade 刃 (phonetic) + heart 心 (semantic)
忍 is a semantic-phonetic compound: 心 'heart' below gives the meaning, while 刃 'blade' above provides the sound. The image of a blade over the heart vividly suggests enduring pain or restraining oneself, hence the meanings 'endure, bear, be patient'.
