Voice is a crucial aspect of English grammar. It indicates if the subject of the sentence is performing the action or if the action is performed on the subject. To know the difference between the active and passive voice, contributing to the improvement of writing, speaking, and sentence clarity. In this article, you will learn the meaning of active and passive voice, important rules, sentence structures, examples, and tips to easily change sentences from active voice to passive voice.

What is Active Voice?

Active voice: The subject of the sentence is doing the action. It renders sentences easy to understand, simple, and clear to readers and hearers. In common usage, active voice is employed in writing or speaking to impart information in a more direct manner.

Why do we use Active Voice?

Active voice is employed to make sentences clear, direct and easy for understanding. It can be used to make it easier for readers to understand what is happening and who is doing the action, which makes communication and sentence flow easier. Active voice is seen more often in conversational, academic, blogs, and professional writing because it conveys a more natural and engaging tone.

Structure of Active Voice

She Writes a letter

Subject + Verb + Object

• Subject → She
• Verb → writes
• Object → a letter

So, the subject (She) is the does of the action, the verb (writes) shows the action, and the object (a letter) receives the action.

Examples of Active Voice

• Rahul writes a letter.
• The teacher explains the lesson.
• She completed the project yesterday.
• The dog chased the cat.

In all these examples, the subject is doing the action.

What is Passive Voice?

Passive voice is a way of arranging a sentence that shows the person or thing receiving the action rather than the person or thing doing the action. It is used primarily only when the action or the result is more important than the person or thing that is responsible for the action. Passive sentences are frequently used in formal writing, reports, academic writing, and official writing.

Why Do We Use Passive Voice?

When the action or result is more important than the person who performs it, use passive voice. It is also useful when the agent of the action is not explicitly stated or otherwise implied. Passive voice is often used in formal writing, scientific papers and reports, news articles, and official announcements.

Structure of Passive Voice

A letter is written by Rahul

Object + Helping Verb + Past Participle + by + Subject

• Object → A letter (This is the receiver of the action and comes first in passive voice.)
• Helping Verb → is (Supports the main verb and shows tense.)
• Past Participle → written (The main verb in passive form.)
• By → by (Introduces the doer of the action in passive voice.)
• Subject → Rahul (The original doer of the action, placed after “by.”)

Examples of Passive Voice

• The lesson is explained by the teacher.
• The project was completed by her yesterday.
• The cat was chased by the dog.

Here, the focus is on the action or the receiver of the action.
