Semantic Notes
The word spans entomology (literal insect larva), informal/colloquial speech (food), and a verb describing rough searching/digging. Its meaning is highly context-dependent.
Dialectal Variation
British vs American Usage
Differences
Minimal. Both use all senses, though 'grub' as slang for food is slightly more informal in both. The verb 'to grub about/around' (to search untidily) is perhaps more characteristically British.
Connotations
Informal, often unappetizing, basic, or cheap when referring to food ('pub grub'). The insect sense has negative connotations of dirt and pests.
Frequency
As a noun meaning 'food', it's moderately common in casual speech. The insect sense is less frequent, used in nature contexts. The verb is less common.

Common Pitfalls
Translation Traps (for Russian speakers)
- Not a direct translation for "еда" (food) in formal contexts.
- Not a general word for "насекомое" (insect) – only the larval stage.
- Verb "to grub" is not "жаловаться" (to grumble), but "копаться/рыться".
Common Mistakes
- Using 'grub' in formal writing for 'food'.
- Confusing 'grub' (n.) with 'grab' (v.).
- Using the verb without the required particle (e.g., 'He grubbed the roots' is odd; 'He grubbed up the roots' is correct).
