Tips
usage
Read lù in the everyday words 忙碌 ('busy') and 碌碌无为 ('mediocre, achieving nothing'). The separate liù reading appears only in the farm-tool word 碌碡 (a stone roller).
The stone radical on the left points to the character's origin as a word about stones (it once meant common, ordinary rock), which gave rise to the figurative sense of being commonplace.
