When is passive voice useful?

In one line

The rule

In passive voice, the object of an active sentence becomes the subject, and the doer (subject) is often left out or added at the end.

For example: The ball was kicked (by Ravi).

Let's understand it simply

Imagine you are watching a cricket match. You care about the ball being hit for a six, not always who hit it. If you say, "The ball was hit for a six," you are using passive voice. The action (hitting the ball) is more important than the player.

How it works

1. Start with an active sentence: "Ravi kicked the ball."
2. Move the object (the ball) to the front: "The ball..."
3. Change the verb to a form of 'be' + past participle: "was kicked"
4. Add the doer (by Ravi) if needed, or leave it out.
5. The sentence becomes: "The ball was kicked (by Ravi)."

The story behind it

English has both active and passive forms. Writers and speakers needed a way to talk about actions when the doer is unknown, unimportant, or obvious. Over time, passive voice became a tool for this purpose.

Where you see it in real life

• News reports: "A new bridge was built in the city." (Who built it is not important)
• Science experiments: "The solution was heated to 80°C." (Focus on the process, not the person)
• Instructions: "The onions are chopped finely." (Recipe steps focus on what to do)
• Accident reports: "The window was broken." (We may not know who did it)
• Official notices: "The meeting has been postponed."
• Results: "The match was won by India."

Why it matters

• Helps you write formally and politely, especially in reports and science.
• Useful when you don't know or don't want to say who did the action.
• Makes writing less personal and more objective.
• Needed for many exam answers and official letters.

Common mistakes

• Using passive voice when active voice is clearer. ("Mistakes were made" is less clear than "I made mistakes.")
• Forgetting to change the verb form correctly. ("The ball kicked by Ravi" is wrong; it should be "was kicked.")
• Overusing passive voice, making writing dull or confusing.

Remember it

Use passive voice when the action or result is more important than who did it.
