Typical behaviour: used to + infinitive
Meaning
We use used to + infinitive to talk about past habits and states which are now finished.
- I used to smoke, but now I’ve stopped. (not
I was used to smoke …) - That casino used to be a cinema.
Only past
Used to … has no present form (and no progressive, perfect, infinitive or -ing forms). To talk about present habits and states, we usually just use the simple present tense (see here).
- He smokes. (not
He uses to smoke.) - Her brother still collects stamps.
Questions and negatives
When questions and negatives are written, they often have did … used instead of did … use. Many people consider this incorrect.
- What did people use(d) to do in the evenings before TV?
- I didn’t use(d) to like opera, but now I do.
The contraction usedn’t is also possible, especially in British English.
- I usedn’t to like opera.
But the most common negative is never used …
- I never used to like opera.
In a formal style, questions and negatives without do are possible, but these are not very common, and are rare in American English.
- I used not to like opera, but now I do. (or I used to not like opera …) (BrE)
- Used you to play football at school? (BrE)
These forms are not used in tags.
- You used not to like him, did you? (not
… used you?)
When used to … is not used
Used to refers to things that happened at an earlier stage of one’s life and are now finished: there is an idea that circumstances have changed. The structure is not used simply to say what happened at a particular past time, or how long it took, or how many times it happened.
- I worked very hard last month. (not
I used to work very hard last month.) - I lived in Chester for three years. (not
I used to live in Chester for three years.) - I went to France seven times last year. (not
I used to go to France seven times last year.)
Word order
Mid-position adverbials (see here) can go before or after used. The position before used is more common in an informal style.
- I always used to be afraid of dogs. (informal)
- I used always to be afraid of dogs. (formal, and rare in AmE)
Pronunciation
Note the pronunciation of used /juːst/ and use /juːs/ in this structure.
used + infinitive and be used to …ing
Used + infinitive has a quite different meaning from be used to …ing (see here). Compare:
- I didn’t use to drive a big car. (= Once I didn’t drive a big car, but now I do.) (not
I wasn’t used to drive a big car.) - I wasn’t used to driving a big car. (= Driving a big car was a new and difficult experience – I hadn’t done it before.)
used to and would
Used to and would can both refer to repeated actions and events in the past.
- When she was old, she used to / would sit in the corner talking to herself for hours.
- Sometimes he used to / would bring me little presents without saying why.
But only used to can refer to past states. Compare:
- When we were children we used to / would go skating every winter.
- I used to have an old Rolls-Royce. (but not
I would have an old Rolls-Royce.)
And we use used to, not would, to talk about regular and important habitual behaviour.
- Robert used to play a lot of football. (not
Robert would play …) - I used to smoke. (not
I would smoke.)
