Understanding Voice 

Voice is that form of a Verb which shows whether what is denoted by the subject does something or has something done to it. Or the voice of a verb tells whether the subject of the sentence performs or receives the action.

Subject, Verb and Object

To grasp the concept of voice, we need to understand three basic terms:

•  Subject:  The doer of the action.
•  Verb:  The action performed by the subject.
•  Object:  The receiver of the action performed by the subject.

Now, let's explore the different types of voice in detail.

Types of Voice

1. Active Voice: In active voice, the subject is the doer of the action. The focus is on the subject performing the action.
2. Passive Voice: In passive voice, the subject is the receiver of the action. The focus is on what is being done to the subject.

Understanding the Types of Voices 

Now, examine the following sentences carefully.

• Raghav sold his old car. (Active voice)
• His old car was sold by Raghav. (Passive voice)

Q. What is the action being performed in both sentences?

Selling = Verb

Q. Who is selling?

Raghav = Subject

Q. What is being sold?

Old car = Object

• No matter whether the sentence begins with ‘Raghav’ or ‘His old car’, the performer of the action of selling is ‘Raghav’. Therefore ‘Raghav’ is the subject.
• And the sentence beginning with the subject ‘Raghav’ i.e. Raghav sold his old car, is in active voice whereas the sentence beginning with ‘His old car’, the receiver of the action (object) i.e. His old car was sold by Raghav is in passive voice.
• So, now, it is crystal clear that if you understand who the performer of the action is, it becomes very easy to decide whether the sentence you want to form will follow the syntax of Active or Passive voice.

Active Voice: A verb is said to be in the Active Voice when the person or thing denoted by the subject is the doer of the action (when the subject acts or is active ). 

Passive Voice: A verb is said to be in the Passive Voice when the person or thing denoted by the subject is the receiver of the action (when the subject is passive/acted upon). 

Change of Voice

While changing a verb from Active voice to Passive voice, the following general rules should be followed:

1. The object of the active verb is made the subject of ‘ the passive verb.
2. The subject of the active verb is made the object of the passive verb. This object is preceded by a preposition mostly ‘by’; in some cases, ‘to’ or ‘with’. It will be elucidated further in the chapter.
3. The passive voice must contain the third form of the main or finite verb.
4. Helping verb is placed before the main verb.
5. The tense of the verb does not change.
6. The form of the verb is changed according to the tense.
