The Function of Auxiliary or Verb TO BE. A sentence is a group of words usually containing a verb, that expresses a thought in the form of a statement, question, instruction, or exclamation which, when they are written down, begin with a capital letter and end with a full stop, question mark, or exclamation mark.
From the meaning of sentence above, we can conclude that verb plays important role in a sentence, but what should we do when there is no real verb in making a sentence? The solution is by adding an auxiliary.
What are auxiliary verbs? Auxiliary verbs are also called helping verbs. Auxiliary verbs are used to help/assist the main verb of the sentience.
In this post I want to share about one kinds of auxiliary. It is about auxiliary verb TO BE. The topic I’ll share is kind of TO BE, the function and the examples in using TO BE.
- Kinds of TO BE
There are eight kinds of TO BE, they are:
It can be difficult to understand the meaning.

- The function of TO BE
There two functions of TO BE. They are:
A. As Auxiliary
TO BE is function as auxiliary when there is a main verb (verb) after TO BE in a sentence. It can be followed by two kinds of Main Verb. They are:
- Verb1 + ing (the sentence is in Progressive or Continuous Tense). And the form is
To be + Verb1 + ing
I am speaking English. (Present Continuous Tense)
She was playing a game. (Past Continuous Tense)
They have been finishing their job. (Present Perfect Continuous Tense)
When TO BE is followed by main verb, the main verb should be in third form (Verb3). And the sentence in which verb3 follows TO BE is called Passive Voice. The form is
TO BE + Verb3

B. As Main Verb
TO BE is function as Main Verb or Full Verb (commonly called Verb) when there is no main verb (verb) after TO BE in a sentence. In this case TO BE is directly followed by adjective, adverb or Noun.
