趁机
chènjī · HSK 7
to seize an opportunity
⏰🎯 chèn sounds like CHEN who checks the jī (machine) for the right moment
趁 means 'to take advantage of a moment' and 机 means 'opportunity/machine.' Together: seizing the opportunity. Chen always has his hand on the machine trigger, waiting for the perfect jī (chance) to act.
趁 — 走 'walk/run' + 㐱 phonetic
A semantic-phonetic compound: 走 (run, go) gives the meaning of moving or pursuing, while 㐱 (chěn) supplies the sound. The original sense was 'to chase after' or 'pursue,' which extended to 'take advantage of (a moment),' as in 趁机 'seize the chance.'
