不惜
bùxí · HSK 7
not hesitate
💪 bù (not) + xí (pity/spare) = not sparing anything, holding nothing back
When you spare nothing, you go all in without hesitation. The second character 惜 has the heart radical 忄 plus 昔 (past), suggesting clinging to what was. 不惜 negates that clinging: let go of cost, effort, or risk.
不 — single pictograph; bird flying upward
Originally a pictograph in oracle bone script, traditionally interpreted as a bird flying up toward the sky and unable to come down, suggesting negation or refusal. Over time it became the standard negation word in Chinese, used before verbs and adjectives to mean 'not'.
