愚蠢
yú chǔn · HSK 7
stupid
🐛 yu chun sounds like you churn out nonsense, acting silly and stupid
Breakdown: 愚 sits on 心 (heart) for a foolish heart, and 蠢 stacks 春 (spring) over two 虫 (worms) for sluggish bugs. A churning heart plus dull spring worms add up to silly and stupid.
蠢 — insect 虫 doubled below + spring 春 above
A semantic-phonetic compound: 春 (chūn, spring) gives the sound, while the two 虫 (insects) below give the meaning. It originally depicted insects stirring and wriggling as they emerge in spring, and the sense extended to 'squirming, foolish, stupid.'
