Question

What is passive and active voice

Answer 1

In most English sentences with an action verb, the subject performs the action denoted by the verb.

    These examples show that the subject is  doing the verb's action.

            

Because the subject does or "acts upon" the verb in such sentences, the sentences are said to be in the active voice.

 

Passive voice

One can change the normal word order of many active sentences (those with a direct object) so that the subject is no longer active, but is, instead, being acted upon by the verb - or passive.

    Note in these examples how the subject-verb relationship has changed.

            

Because the subject is being "acted upon" (or is passive), such sentences are said to be in the passive voice.
