Correctly conjugated verbs communicate to a reader or a listener the meaning behind the the sentence clearly. You can see that in English, the verb to be changes depending on who is the subject.

A conjugated verb is broken down into I, you, he/she/it, we and they. For example, the verb ‘to be,’ conjugated in the present tense is: I am, you are, he/she is, we are, and they are.
