笑 (xiào) means "to laugh" with 10 strokes, radical 竹 (bamboo), HSK 2 on the new exam.
Pronunciation
Meaning
Primary: to laugh
Etymology
Oracle-bone origin
笑 is not attested in oracle bone script. The earliest forms appear in seal script as a phono-semantic compound: 竹 (bamboo) on top over 夭 (a bending human figure) below. The Shuowen Jiezi treats 竹 as semantic, though why bamboo signals laughter is debated; one traditional reading is that laughing makes a person bend like bamboo in the wind.
Form evolution
The seal form shows clear 竹 above 夭. In clerical script the bamboo radical was regularised to the familiar 竹 top (⺮), and 夭 below kept its shape of a figure with tilted head. Modern 笑 has changed little since the clerical standardisation, with the bottom component sometimes miscopied as 天 but canonically written 夭.
How the meaning evolved
The core meaning 'to laugh, to smile' has been stable since the earliest attestations. Extended senses developed early: 笑 can mean to mock or ridicule (嘲笑, 笑话 as a joke or as an object of ridicule), and in poetic usage it describes flowers 'smiling' when they bloom. The negative 'laugh at' sense is as old as the positive one.
Cultural note
The idiom 五十步笑百步 ('he who retreats fifty paces laughs at one who retreats a hundred'), from the Mencius, is a common classical reference students meet early. The 夭 component is the same one that appears in 妖 and 沃, all originally depicting a person with head tilted sideways.
