The basic forms of verbs

Verbs
A verb is a part of speech that tells about an action or a state. In Basic English, there are sixteen verbs used include: be, do, have, come, go, see, seem, give, take, keep, make, put, send, say, let and get. Examples: do exercise, can see, and have been waiting.
The basic forms of verbs
1- base form: used as the infinitive form, with to or without to (Do you want to play with us? I can’t sleep now.) and for the present simple (I always read before I go to sleep.) except third person singular, which uses the -s form (Sami works at the university.)
2- past form: used for the past simple (He opened the door and went out.)
3- ed form: used after auxiliary have and be (I’ve always wanted a guitar and I was finally given one yesterday).
Examples of the three basic forms
