Gnaw on Meaning in English
expression
Definition
To bite or chew something repeatedly, usually something hard, using your teeth. It often describes animals chewing bones or objects, and can also refer to a feeling that troubles someone constantly.
Usage & Nuances
Usually informal. Common with animals ('dogs gnaw on bones'), but also idiomatic for worries or doubts ('a problem gnaws on me'). Not the same as 'chew'—'gnaw on' suggests biting persistently, often leaving marks. Used for both physical and emotional contexts.
