English verbs come in three basic forms:
The simple present e.g. play "Let's play chess."
The simple past e.g. played "I played my guitar yesterday."
The past participle e.g. played "Have you ever played golf?"
We add -ed to the end of simple present verbs to make regular simple past and past participle verbs.
Irregular verbs don not follow this rule. In fact, they don't really follow rule!
English learners must learn the forms of irregular forms.
