Bit or Bitten
Short answer:
- Bit = simple past tense
- Bitten = past participle (used with has, have, had, was, were)
Examples:
- ✅ The dog bit my hand.
- ✅ I was bitten by a dog.
- ❌ I was bit by a dog. (informal, not grammatically correct)
If you use was, were, has, have, or had, you usually need bitten.

The Origin of Bit or Bitten
The verb bite comes from Old English bītan, meaning to cut with teeth. Over time, English kept strong (irregular) verb forms.
Verb forms of bite:
- Base form: bite
- Past tense: bit
- Past participle: bitten
The spelling difference exists because English kept older Germanic verb patterns instead of making all verbs regular. That is why we say bitten and not bited.
This history explains why bit or bitten grammar feels confusing. Both forms are correct, but only in the right structure.
