耐性
nài xìng · HSK 7
patience
🐢 耐 endure + 性 nature = the endure-quality, your capacity to bear and last
耐 — 而 (beard) + 寸 (hand/rule)
Originally depicted shaving off a beard (而) by hand (寸) as a minor punishment in ancient China. The sense shifted from 'enduring this shame' to the broader meaning 'to endure, bear, withstand.' Today 耐 commonly means patient or resistant, as in 耐心 (patience).
性 — heart radical 忄 + 生 (life/birth)
性 is a semantic-phonetic compound. The heart radical 忄 supplies the meaning, pointing to inner feelings or innate qualities, while 生 ('birth, life') gives the sound and hints at what one is born with. It originally meant 'inborn nature' and later extended to 'character,' 'gender,' and 'sex.'
