Used To vs Would
used to for states and habits; would only for habits.
Examples
- I used to be shy.
Key rules
- Used to: past habits and past states
- Would: past repeated actions only, not states
- Negative: didn't use to
- Do not use would for state verbs like be, have, know
Common mistakes
- I would live in Paris as a child → I used to live in Paris as a child
- He didn't used to smoke → He didn't use to smoke
💡 Tip: Use used to if you are unsure.
