ACTIVE AND PASSIVE VOICE


DEFINITION OF ACTIVE AND PASSIVE VOICE

Active Voice
A feature of sentences in which the subject performs the action of the verb and the direct object is the goal or the recipient
Example : The mechanic fixed the car.

Passive Voice
A feature of sentences in which the object or goal of the action functions as the sentence subject and the main verb phrase includes the verb to be and the past participle
Example : The car was fixed by the mechanic.

Notes

·         The object of the active verb becomes the subject of the passive verb. The subject of the active verb becomes the object of the passive verb.

·         Note that the object of the passive verb is not always mentioned. If we have to mention it, we usually introduce it by the conjunction ‘by’.



TRANSITIVE AND INTRANSITIVE VERBS
·         Definition of transitive and intransitive verbs

-          Transitive Verbs
Transitive verbs are action verbs that have an object to receive that action. In the first sentence above, the direct object ball received the action of the verb hit.
     
Example :
I cooked some cookies
I moved the chair.
I stitched a quilt.

**All of the verbs in the above sentences are transitive because an object is receiving the action of the verb.

-          Intransitive Verbs
Intransitive verbs are action verbs but unlike transitive verbs, they do not have an object receiving the action.

Example :

I laughed.
I cried.
The sun set.

** In all of the above cases the subject is performing the action of the verb and nothing is receiving the action.
