Active and Passive Voice
Voice: Voice is the term used to describe whether a verb is active or passive in active and passive voice.
Active Voice: A sentence which begins with the performer of the action (subject), then the verb,then the object or person that the action is performed on. This is called an active sentence.
- Ali Washed the dishes.
Sub + Verb + Object.
Passive Voice: A sentence which begins with the object or person that the action is performed on is called passive sentence.
- The dishes were washed (by Ali.)
Object + verb + (by subject)
When Should we use the Passive Voice?
1. When we do not know who the subject is, or it is not important who the subject is.
- Somebody cleaned the room. (Active) The room was cleaned. (Passive)
2. When it is obvious to the listener or reader who the subject is because it is the person who usually does it.
- The cleaner cleaned the room. (Active) The room was cleaned. (Passive)
3. When we give more importance to the object of the sentences rather than the subject, we use passive voice.
- The glasses were broken. (We give importance to the object not to the subject)
