退缩
tuì suō · HSK 7
to shrink back
🐢 退 retreat + 缩 shrink = retreat-and-contract, like a turtle pulling its head in
退 (tuì) means retreat or step back; 缩 (suō) means to contract or shorten. Together: to draw back and shrink away from a challenge. The sound suō also starts 缩短 (suōduǎn), to shorten.
退 — walk radical 辶 + 艮 (stop/halt)
退 combines the walking/movement radical 辶 with 艮, which carries a sense of stopping or turning back. Together they depict the action of moving backward or withdrawing. The original sense of retreating or stepping back has remained stable through history.
缩 — silk radical 糹 + 宿 (lodge, phonetic)
A semantic-phonetic compound. The silk radical 糹 carries the meaning, since shrinking and tightening were associated with drawing in cords or fabric. The right side 宿 (sù) supplies the sound. The original sense of binding cloth tight extended to the modern meaning 'to shrink' or 'contract.'
