Voice in English Grammar
In English grammar, voice refers to the form of a verb that shows whether the subject performs the action or receives the action. There are two types of voice:
- Active Voice
- Passive Voice
Understanding voice is important for sentence transformation and is commonly tested in competitive examinations.
Active Voice
A sentence is in active voice when the subject performs the action.
Structure:
Subject + Verb + Object
Examples:

Passive Voice
A sentence is in passive voice when the subject receives the action.
Structure:
Object + form of be + Past Participle + by + Subject
Examples:

Rules for Changing Active Voice to Passive Voice
- The object of the active sentence becomes the subject of the passive sentence.
- The verb is changed into the past participle form.
- A suitable form of the verb be is used.
