Meaning and Usage
The verb 啃 (kěn) primarily means "to gnaw" or "to bite repeatedly," often used literally for animals or people biting something hard like bones or food. It can also be used metaphorically to describe diligent study or effort, as in "啃书本" (gnawing on books), implying persistent hard work.
Common Collocations
- 啃骨头: literally gnawing bones, used for animals or children.
- 啃书本: figuratively means to study hard.
- 啃老: a colloquial phrase meaning to rely financially on one's parents, often due to economic hardship.
Usage Notes
啃 is often used in informal contexts. When used metaphorically, it conveys a sense of persistence or difficulty. The phrase 啃老 is somewhat slangy and can carry a negative connotation about dependence. Avoid confusing 啃 with 咬 (yǎo), which means "to bite" but usually refers to a single bite rather than continuous gnawing.
Register and Tone
啃 is neutral to informal in tone. It is common in spoken language and informal writing but less so in formal texts unless used metaphorically or idiomatically.
