Clasificación de verbos

Verb Classification
We divide verbs into two broad classifications:

1. Helping Verbs

Imagine that a stranger walks into your room and says:
• I can.
• People must.
• The Earthwill.
Do you understand anything? Has this person communicated anything to you? Probably not! That's because these verbs are helping verbs and have no meaning on their own. They are necessary for thegrammatical structure of the sentence, but they do not tell us very much alone. We usually use helping verbs with main verbs. They "help" the main verb. (The sentences in the above examples aretherefore incomplete. They need at least a main verb to complete them.) There are only about 15 helping verbs.

2. Main Verbs

Now imagine that the same stranger walks into your room and says:
• Iteach.
• People eat.
• The Earth rotates.
Do you understand something? Has this person communicated something to you? Probably yes! Not a lot, but something. That's because these verbs aremain verbs and have meaning on their own. They tell us something. Of course, there are thousands of main verbs.
In the following table we see example sentences with helping verbs and main verbs.Notice that all of these sentences have a main verb. Only some of them have a helping verb.
