Passive voice

voice which is not active in grammar, passive form of a transitive verb (Grammar)

In grammar, the voice of a verb describes the relationship between the action (or state) that the verb expresses and the participants identified by its arguments (subject, object, etc.). When the subject is the agent or actor of the verb, the verb is in the active voice. When the subject is the patient, target or undergoer of the action, it is said to be in the passive voice.
