Irregular verbs have a different form, usually with a different vowel sound (e.g. go → went, feel → felt).
I _____ (wake) up early this morning.
I ______ (break) my leg yesterday.
We make the negative with didn't and the infinitive verb.
My parents didn't call me yesterday.
I didn't wake up early this morning.
We make the question form with did and then the subject and infinitive verb.
Did you wake up early this morning?
Did Sam play basketball when he was at university?
