冷笑
lěng xiào · HSK 7
to laugh grimly
❄️😏 冷 cold + 笑 laugh = a cold laugh, i.e. a sneer
冷 (cold) plus 笑 (laugh/smile) literally stacks to a cold laugh. The chill carries the bitterness and contempt, so 冷笑 is a grim, scornful sneer rather than a warm grin.
冷 — ice radical 冫 + order 令
A semantic-phonetic compound. The left side 冫 (ice) supplies the meaning of coldness, while 令 (lìng, 'command/order') hints at the pronunciation. Originally referring to the chill of ice, 冷 broadened to mean cold in general, and figuratively cool, indifferent, or detached.
笑 — bamboo radical 竹 (⺮) + 夭 (yāo, bending)
Originally written with the bamboo radical over 夭, depicting a person bending or swaying. One traditional reading is that bamboo bends in the wind like a person doubling over with laughter. The character has meant 'laugh, smile' since early times, with no major shift in meaning.
