How do I change a passive sentence back to active voice?

In one line

The rule

In passive voice, the subject receives the action; in active voice, the subject does the action.

Formula:

• Passive: Subject + form of 'to be' + past participle (V3) + (by + agent)
• Active: Agent (doer) + verb + object

Let's understand it simply

Imagine you see this sentence: "The ball was kicked by Rohan." Here, the ball is getting kicked. Rohan is doing the action. In passive voice, the focus is on the ball. To make it active, you put Rohan (the doer) first: "Rohan kicked the ball." Now, Rohan is the subject, and he is doing the action. It’s like in cricket: "The ball was hit by Virat." Change it to "Virat hit the ball."

How it works

1. Find the agent (the doer) in the passive sentence (usually after 'by').
2. Make the agent the subject of the new sentence.
3. Change the verb to match the tense and make it active (remove 'was', 'is', 'are', etc.).
4. Put the receiver (old subject) after the verb as the object.
5. Remove 'by' and the agent from the end.

The story behind it

The idea of active and passive voice comes from how people want to focus on either the doer or the action. English grammar rules were shaped over hundreds of years to help people write clearly. Teachers and writers noticed that sentences are easier to understand when the doer comes first.

Where you see it in real life

• School reports: "The homework was completed by Anjali." → "Anjali completed the homework."
• Cricket commentary: "The six was hit by Dhoni." → "Dhoni hit the six."
• Kitchen: "The tea was made by Amma." → "Amma made the tea."
• Market: "The vegetables were bought by Papa." → "Papa bought the vegetables."
• News: "The match was won by India." → "India won the match."

Why it matters

• Makes your writing clearer and more direct.
• Helps in exams where you are asked to change voice.
• Useful for speaking and writing in English, especially in job applications and essays.
• Many instructions and signs use active voice for clarity.

Common mistakes

• Forgetting the agent: Sometimes the doer is missing in the passive sentence. You cannot change to active if you don't know who did it.
• Wrong verb tense: Students often forget to match the tense. "Was eaten" should become "ate" or "eats" depending on the tense.
• Keeping 'by' in the active sentence: In active voice, you do not use 'by'.
• Changing the meaning: Make sure the action and doer stay the same.

Remember it

To change passive to active: Find the doer, put them first, and use the right verb.
