What is Voice – Active Voice & Passive Voice ? Why is voice needed?
While communicating we use words in a sentence according to the importance ascribed to them. Or in other words are placed in a sentence according to their importance in communication.
Usually a sentence has a subject, a verb and an object in it. A word is used as subject or object in a sentence according to the importance it carries with it.
Take the following examples to make it clear.
1. I wrote a letter to him.
2. I wrote him a letter.
3. A letter was written to him by me.
In these sentences the three key words I, letter and him are placed at different places in the sentences according to the importance of these words in communication. As such the two forms of voice i.e. Active and Passive voice are used accordingly while communicating. More important words are used as Subject and those of secondary place are used as an object in a sentence. For this necessary changes are made in the sentence.
The process of making a change from active to passive form of a sentence is called ‘change of the voice’.
A sentence generally has in it a Subject , Verb and object. But some sentences do not have an object but for change of voice an object in a sentence is necessary.
Change of Voice –
While changing a sentence from active to passive form, we bring object in place of subject and move subject to the place of object. A word ‘by’ is used before subject (at object place) of course with some exceptions. The remaining part of the sentence (other than Subject, verb and object) is placed after the third form of verb used in the sentence.
