I am a learner of English and found these definitions somewhere on the Internet about helping verbs and action verbs. Are they correct? They sound fine to me but I want to make sure because I have not learned English through rules.
Helping verbs are usable in tenses to tell us time frames and we call them as helping verbs because they do not have any meaning, they just help us to inform about time frames of actions.
Action verbs help us to complete actions and helping verbs tell us when those actions happened.
