With easy verbs, you add -ed to the end for past tense. Those are called regular verbs.
Irregular means “not regular“. They are strange, and we have a lot of them.
My favorite teacher, Ronnie, has a good lesson. She explains that there are three types of these verbs. That helps make it easier!
She also has this nice list to study.
She mentions some special kinds of past. To learn more, see the lessons about past perfects and past participle.
