It is important for the CLAT and other Law entrance examination aspirants to have good knowledge of active-passive voice as questions on this topic can be asked directly or in the form of ‘spotting the error’ or in the questions of ‘passage completion’ so one should be clear about its rules.
For solving questions on active-passive voice one should also have knowledge regarding types of sentences, forms of verb and forms of tense because their rules help with the correct conversion of voice.
Meaning of voice
The voice of a verb tells whether the subject of the sentence performs or receives the action. Voices are of two types: active and passive.
Active Voice: In the active voice, the subject performs the action expressed by the verb.
Eg.- Ram sings a song.
Here ‘Ram” is the subject and the verb is ‘sing’ and ‘song’ is the object. Here the action of ‘singing’ is being done by the subject i.e. ‘Ram’.
Passive Voice: In passive voice subject receives the action expressed by the verb.
Eg.- A song is sung by Ram.
Here the ‘song’ is subject ‘sing’ is the verb and ‘Ram’ is the entity who did the action of singing and ‘song’ is the entity on whom action has been done.
General rules of conversion active voice to passive voice:
- The subject in the active voice becomes the object in the passive voice and the object in the active voice becomes the subject in the passive voice.
- Put ‘by’ in front of the subject in the passive voice.
- Use 3rd form of verb + is/ am/ are/ was/ were/ been/ being according to the tense in passive voice.
- The following pronouns are used in the passive voice as:
Active Voice | Passive Voice |
I | me |
He | him |
You | you |
We | us |
She | her |
They | them |
It | it |
Who | whom |
- There is no passive voice of present/ past/ future perfect continuous sentences and future continuous.
- Generally, passive voice can be made of transitive verb i.e. verbs which have an object attached to them.
Sentences of an intransitive verb cannot be converted into passive voice.
- They laughed- No passive
- The laughed at- The teacher was laughed at by them.
In the first sentence, there is no object thus it cannot be converted into passive voice.
But in the second sentence ‘teacher’ is the object thus its passive voice is possible.
General rules of conversion from passive voice to active voice
- The subject of passive voice becomes object in active voice and the object in passive voice becomes the subject in active voice.
- Remove the preposition ‘by’.
- Use 1st form of the verb.
Let us understand the conversion from active to passive voice with the verb ‘sing’ in the following forms of tense.
Tense Verb (Active) Verb (Passive)
Simple present sing/ sings am/ is/ are sung
Simple past sang was/ were sung
Simple future sung shall/ will be sung
Present continuous is/ am/ are singing is/ am/ are being sung
Past Continuous was/ were singing was/ were being sung
Present Perfect has/ have sung has/ have been sung
Past Perfect had sung had been sung
Future Perfect will/ shall have sung will/shall have been sung

Passive: My watch has been stolen herein object it is no need to write ‘someone’.
