"The least you need to know"
Besides the obvious action verbs, there are other verbs that appear regularly. These words are often missed because they "don't look verby." Although they go by different names, you will probably never be asked to tell them apart. The important thing to know is they function as a verb that expresses existence or being.
A linking verb does not show action. Instead, it LINKS the subject to a word that either describes the subject or gives the subject another name. (Nomitive)
Michael is a monster. I am a loner. Maivis was the last person in line.
Am Is Are Was Were
-Helping verbs/auxiliary verbs/ state of being
Although they go by different names, they all function as verbs. A helping verb is to help the main verb in a sentence. Together they make up a VERB PHRASE
Examples- "Jerry has gone to the game." "I am waiting for the bus."
Am Have Could Might
Is Had Will Must
Are Been Would
You will notice some similarities so memorizing the differences is important, but not as important as recognizing its function.
There is also another list of words that SOMETIMES function as helping verbs/ auxiliary verbs/ state of being verbs and sometimes they are action verbs. These verbs are the exception to the Good Vs. well argument. So "Bacon tastes good" is acceptable.
I can't see the T.V.
"Not" is not a verb. So only the "can" part is the verb.
