I had a confusion between Infinitive form of the verb and the base form of the verb. But this LINK explains the difference between infinitive and base form of the verb.
Base form: be, have, hold, sleep, dream
Infinitive form: to be, to have, to hold, to sleep, to dream
Can we write all helping verbs in infinitive form which are mentioned below:
- be (including am, is, are, was, were, been)
- have, has had
- do, does, did
I know these exists to be, to do, to have, but do others?
