Voice: Voice is a grammatical category that applies to the verb in a sentence. It shows the relationship between the doer of an action (subject) and the receiver of that action (object).
There are two types of voices in English-
• Active voice
• Passive voice
A verb is in the Active Voice when the person or thing denoted by the Subject is the ‘doer’ of the action.
• E.g. He kicks the ball.
General structure: Subject + verb + object
A verb is in the Passive Voice when the person or thing denoted by the Subject is the ‘receiver’ of the action.
• E.g. The ball is kicked by him.
General structure: Object + helping verb + V3 + by + subject
Basic rules to change active voice into passive voice:
• Change the places of subject and object.
• Use the helping verb according to the tense.
• Use third form of the verb.
• Add ‘by’ if necessary.
• If the subject is a pronoun, change it into the objective case.
Rules based on tense:
• In simple tenses, ‘is/am/are, was/were and will be/shall be’ is used.
• In continuous tense ‘being’ is used.
• In perfect tense ‘been’ is used.
