Voice

Practical English Grammar

Voice is the form of the verb which expresses whether a subject in a sentence performed or received the action. There are two kinds of voice:

1. Active Voice

The verb is in the active voice when the subject of the sentence performs an action. In other words, when the subject performs an action, the verb is in the active voice. Active voice is used to show the straightforward relations and clarity between the subject and the verb.

Basic formula for Active Voice Sentence: Subject + Verb + Object

Examples:
I am playing cricket.
He is drinking tea.
She taught me.
Ram is writing a letter.


2. Passive Voice

The verb is in the passive voice when the action is performed on the subject of the sentence. In other words, when an action is performed on the subject, the verb is in the passive voice. Passive voice is used to bring focus on the action and not the subject. Passive voice is also used when it is not known who performed the action.

Basic formula for Passive Voice Sentence: Object (subject of Active Voice) + Verb + Subject (object of Active Voice)

Examples:
Cricket is being played by me.
Tea is drunk by him.
I was taught by her.
A letter is written by Ram.

Rules to change the Active Voice into Passive Voice

1. In passive voice, the subject and object of active voice get interchanged. Sometimes the subject of active voice is omitted to give importance to the action or the subject is insignificant. When the subject of active sentence is changed into an object of passive sentence, it is often preceded by a preposition (by, with, to, etc.).

2. The base verb of active sentence is changed in the past participle (third form verb) in a passive sentence and suitable helping verb (is/am/are/was, etc.) in accordance with the tense of the sentence is used before the main verb.

3. While converting the active voice sentence to passive voice sentence, the pronoun gets changed from nominative caste in active voice sentence to the objective case in a passive voice sentence.
