Active & Passive Voice (वाच्य)
🎯 The Hook
Imagine two headlines:
- "The police arrested the thief."
- "The thief was arrested by the police."
Same event. Same thief. Same police. Yet the *focus* has completely shifted — in the first sentence, the police are the star; in the second, the thief is. This magical ability to shift the spotlight of a sentence is called Voice, and it is one of the most frequently tested grammar topics in SSC, Railway, Bank and State exams. Master it once, and you will never lose these marks again.
📌 Learning Objectives
By the end of this chapter, you will be able to:
- Identify whether a sentence is in Active or Passive Voice.
- Convert any tense from Active to Passive (and back) using a fixed formula.
- Handle special cases — modals, imperatives, questions, and sentences with two objects.
- Spot the examiner's favourite traps instantly.
1. What is Voice?
Voice tells us whether the subject of a sentence *performs* the action or *receives* the action.
- Active Voice → The subject *does* the action.
*Ram eats a mango.* (Ram = doer) - Passive Voice → The subject *receives* the action.
*A mango is eaten by Ram.* (Mango = receiver)
The Golden Formula for Passive:
> Object + be-verb (is/am/are/was/were/been/being) + V3 (Past Participle) + by + Subject
The tense never changes — only the *form* of the verb changes. "Eats" becomes "is eaten"; the time (present) stays the same.
🧠 Active Recall
- In "The letter was written by Sita," who is the doer of the action?
- What two parts must every passive verb contain?
*(Answers: 1. Sita — she performs the writing even though "letter" is the subject. 2. A be-verb + V3 (past participle) — e.g., "was written". The object and the "by + doer" belong to the sentence, not to the verb itself.)*
2. The Conversion Rule — Step by Step
To change Active → Passive, follow these four steps:
- Swap positions: The object of the active sentence becomes the subject of the passive sentence.
- Choose the correct "be" form according to the tense and the new subject.
- Use V3 (third form) of the main verb.
- Add "by" + doer (omit the doer if it is unknown or unimportant).
Example (Present Simple):
- Active: *She teaches English.*
- Passive: *English is taught by her.*
Example (Past Simple):
- Active: *Mohan broke the window.*
- Passive: *The window was broken by Mohan.*
🧠 Active Recall
Convert: "The cat chased the mouse."
*(Answer: The mouse was chased by the cat.)*
3. Tense-wise Conversion Table
| Tense | Active | Passive |
|---|---|---|
| Present Simple | He writes a letter. | A letter is written by him. |
| Present Continuous | He is writing a letter. | A letter is being written by him. |
| Present Perfect | He has written a letter. | A letter has been written by him. |
| Past Simple | He wrote a letter. | A letter was written by him. |
| Past Continuous | He was writing a letter. | A letter was being written by him. |
| Past Perfect | He had written a letter. | A letter had been written by him. |
| Future Simple | He will write a letter. | A letter will be written by him. |
| Future Perfect | He will have written a letter. | A letter will have been written by him. |
⚠️ Note: Perfect Continuous tenses (has been writing, had been writing) and Future Continuous (will be writing) are NOT converted into passive in standard exam English.
🧠 Active Recall
- What is the passive of "She has completed the work"?
- Can "He has been singing" be converted to passive?
*(Answers: 1. The work has been completed by her. 2. No — Perfect Continuous has no passive form.)*
4. Modals in Passive Voice
With modals (can, could, may, might, shall, should, will, would, must, ought to), the structure is simple:
> Modal + be + V3
- Active: *You must obey the rules.* → Passive: *The rules must be obeyed.*
- Active: *She can solve this problem.* → Passive: *This problem can be solved by her.*
Mnemonic 🧠: "M-B-V3" — *Modal, Be, Verb-3* — remember it as "My Best Victory" (M-B-V3). Every modal passive follows My Best Victory!
5. Special Cases
(a) Imperative sentences (orders/requests): Use "Let + object + be + V3".
- *Open the door.* → *Let the door be opened.*
- For advice: *Help the poor.* → *The poor should be helped.*
(b) Questions: Keep the question structure; only the verb changes.
- *Did he write the letter?* → *Was the letter written by him?*
- *Why did she beat the boy?* → *Why was the boy beaten by her?*
(c) Two objects (direct + indirect): Either object can become the passive subject.
- *He gave me a book.* → *I was given a book by him.* / *A book was given to me by him.*
(d) Preposition-verbs: Keep the preposition attached to the verb.
- *They laughed at the beggar.* → *The beggar was laughed at by them.* (NOT "was laughed by them")
🧠 Active Recall
Convert: "Shut the window."
*(Answer: Let the window be shut.)*
⚠️ EXAMINER'S TRAP BOX
Trap 1 — The "by" agent trap: Examiners add "by" where it is not needed. If the doer is obvious or unknown (someone, they, people), drop it: *My wallet has been stolen.* (NOT "by someone").
Trap 2 — The missing "being": In continuous passives, students forget "being": *The work is being done* (NOT "is done" — that is simple present).
Trap 3 — Intransitive verbs: Verbs with no object (go, come, sleep, die, happen) cannot become passive. *"The accident was happened"* is WRONG — "happen" has no object.
🏆 12 Golden Rules of Voice
- Passive verb = be + V3, always.
- Tense never changes during conversion — only verb form changes.
- Object of Active → Subject of Passive.
- Pronouns change: I→me, he→him, she→her, we→us, they→them (and reverse).
- Modals take modal + be + V3.
- Imperatives take Let + object + be + V3.
- Perfect Continuous & Future Continuous have no passive.
- Intransitive verbs (go, die, sleep, happen) have no passive.
- Prepositions attached to verbs stay attached in passive.
- "By" is dropped when the doer is unknown/obvious.
- With two objects, either can become the passive subject.
- Verbs like *said, reported, believed* use: *It is said that…* / *He is said to be…*
🔁 Linguistic Bridge — Hindi vs English
| In Hindi we think… | Wrong English | Correct English |
|---|---|---|
| "मुझसे गलती हो गई" | *By me a mistake was happened.* | *A mistake was made by me.* ("happen" has no passive; use "make") |
| "यह काम किया जा सकता है" | *This work can be do.* | *This work can be done.* (V3, not V1, after "be") |
| "दरवाज़ा खोला गया" | *The door was open by him.* | *The door was opened by him.* ("open" as verb needs -ed) |
| "उसे सज़ा दी गई" | *He was gave punishment.* | *He was given punishment.* (V3 = given, not gave) |
Key habit: After any form of "be" (is/was/been/being), the main verb must be in its third form (V3) — never V1 or V2.

|---|---|---|
| Simple tenses | is/am/are/was/were + V3 | The cake is baked. |
| Continuous | is being/was being + V3 | The cake is being baked. |
| Perfect | has/have/had been + V3 | The cake has been baked. |

🔁 Review after 2 days
Come back after 48 hours and do this without looking:
- Write the passive formula from memory.
- Convert these three: (a) *She is singing a song.* (b) *They have sold the house.* (c) *Do not insult the poor.*
- Name the two tense families that have no passive form.
If you stumble on any point, re-read only that section — spaced repetition is what moves Voice from "studied" to "scored."
