嬉笑
xī xiào · HSK 7
to be laughing and playing
😄 嬉 = frolic (女 + 喜 joy) + 笑 = laugh: laughing while playing
嬉 joins 女 (woman) with 喜 (joy/delight) for the sense of playful frolicking; 笑 means laugh. Stack the two and you get carefree giggling and horsing around.
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.
