逞能
chěng néng · HSK 7
to show off one's ability
💪🦚 chěng sounds like 'showing' + néng means ability — showing off ability
逞 means to flaunt or indulge, 能 means ability or skill. Together they describe someone who insists on displaying their competence, like a peacock spreading its tail to prove its worth.
能 — 厶 (head) + 月 (body/flesh) + 匕匕 (legs)
Originally a pictograph of a bear, showing its head, body, and powerful legs. Because bears were seen as strong and capable, the character was borrowed to mean 'ability' or 'can'. A new character 熊 (with the fire radical 灬) was later created for 'bear'.
