USED TO

USED TO / DIDN'T USE TO

We use 'used to' for something that happened regularly in the past but no longer
happens. To form this you use 'USED TO + INFINITIVE'. We also use it for something that was true but no longer is.

Examples:

• I used to play a lot of computer games but I stopped playing them two years ago.
• I used to write a lot, but now I use the computer.
• There used to be a computer shop in the town but now there isn't

The negative form of 'used to' used to is 'didn't use to'

Example : I didn't use to do my homework.

 

The interrogative form of 'used to' is : Did / Sujet / 'use to' / verbal base 

Example : Did you use to live in London?
