what is passive voice?

Passive voice means the subject of the sentence does not perform the action and is therefore passive.In other words we can say that the doer or performer of the action is not important to the speaker or writer but the thing denoted by the subject is important.

the passive voice is used to indicate that the grammatical subject of the verb is the recipient(not the doer) of the action denoted by the verb.
