To be verbs are things that do not show action. For example, The grandmother is nice.. Is is the to be verb in that sentence. A trick to remember that is Grandmother=nice. If the equals sign makes sense in between the words, then it's a form of a being verb. Sometimes, verbs like is can be used as part of a verb phrase and be an action verb.
Auxiliary verbs. Auxiliary verbs are sometimes called helping verbs because they are needed to form many of the tenses. The most used auxiliary verbs are the verbs to be, to do and to have. For example: the auxiliary to do is needed to ask questions in the present and past simple tenses. To be is needed for the present and past continuous, and all the passive forms. The auxiliary to have is used in the present and past perfect tenses.
