MEANING

                                                         MEANING:

As a main verb in a sentence, to be is a stative verb serving as a copula (a verb linking the subject with its complement). As every sentence in English must have a verb, to be is used in many cases where there is no action described in the sentence.

For examples:

1. I am Dan Smith. She is a doctor. We are from Spain
2. We are from Italy.
3. The sky is blue, and so is my favorite color.
