Active Voice and Passive Voice
In English grammar, verbs have five properties:
voice, mood, tense, person, and number; here, we are
concerned with voice.
The two grammatical voices are active and passive.
Active Voice and Passive Voice
Voice is form of a verb which shows whether the
subject of the verb acts or is acted upon.
There are two kind of voices in English:
i) Active Voice ii) Passive Voice
Active Voice:
The active voice is that in which an act is done by the
subject . The subject is an agent or the real doer of an
act.
Active Voice and Passive Voice
Passive Voice:
The Passive Voice is that in which an act is done in
respect of an object. In this voice , the subject who is
the agent, becomes unimportant. It is the object
which becomes the subject, but which in fact is not the
agent.
Note: The active voice is mostly used in writing
because it gives a direct and more concise meaning.
Passive voice is used sometimes due to the following :
When we don’t know the agent who did an action.
Eg. The bank was robbed yesterday night.
Active Voice and Passive Voice
Sometimes intentionally to hide the subject of the
sentence.
Eg. The question paper was leaked.
When passive voice explains better thought of the
sentence.
Eg. Morals and values are taught.
When passive voice emphasizes the main thought of
the sentence in a better way.
Eg. The culprits will be arrested by the police.
Active Voice and Passive Voice
There are certain rules for expressing a thought in
passive voice or for changing a sentence from active to
passive voice.
Rule for changing from Active voice to Passive voice:
1. From the given sentence the object becomes the
subject of the passive voice and the subject of the
active voice becomes the object of the passive voice.
Eg. Ravi writes a latter. A.V.
Sub. + Verb + Obj.
Active Voice and Passive Voice
A letter is written by Ravi. P.V.
Sub. + be+ V3 + by + Obj.
2.Sometimes passive voice is used with out subject.
Subject of sentence can be omitted in passive voice,
Without subject also it can give enough meaning in
passive voice.
Eg. Mangoes are sold in markets. P.V.
Active Voice and Passive Voice
3. While changing the sentence from A.V. To P.V.
The auxiliary verbs are used in passive voice as per
tense of the given sentence.
Be + P.P.( Past Participle or V3) should be used
according to the tense mood and ‘by’ preposition
should be added before the object.
Eg. She sang songs. A.V.
Sub. + Verb + Obj.
Songs were sung by her.
Sub. + Be+ P.P.(v3) + by+ Obj.
Active Voice and Passive Voice
4. The word or preposition ‘by’ is not always
mandatory to be used before object in passive voice. In
some cases words like ‘with’, ‘to’ etc., may also be used
before the object and without by also be used in
passive voice.
Like know(to), surprise (at), annoy (with), Contain
(in), vex( with), please ( with), displease (at), alarm
(at) etc.
Eg. She knew me. A.V.
I was known to her. P.V.
