passive voice



The passive voice is a grammatical construction (specifically, a "voice"). The noun or noun phrase that would be the object of an active sentence (such as Our troops defeated the enemy) appears as the subject of a sentence with passive voice (e.g. The enemy was defeated by our troops).
The subject of a sentence or clause featuring the passive voice typically denotes the recipient of the action (the patient) rather than the performer (the agent). The passive voice in English is formed periphrastically: the usual form uses the auxiliary verb be (or get) together with the past participle of the main verb.
Form of Passive
Subject + finite form of to be + Past Participle (3rd column of irregular verbs)
Example: A letter was written.
When rewriting active sentences in passive voice, note the following:
  • the object of the active sentence becomes the subject of the passive sentence
  • the finite form of the verb is changed (to be + past participle)
  • the subject of the active sentence becomes the object of the passive sentence (or is dropped)
