Passive Voice Overview
The passive voice is used when the focus is on the action itself rather than on the performer. This is particularly helpful when the doer is unknown or irrelevant.
Example: My bike was stolen.
Here, the emphasis is on the theft, not on who stole the bike.
Passive for Politeness
Passive constructions can make statements sound more polite, avoiding direct blame.
Example: A mistake was made.
This focuses on the error itself, not on assigning responsibility (as in You made a mistake).
Passive Voice Structure
The passive structure is formed by:
Subject + finite form of “to be” + Past Participle
Example: A letter was written.
When transforming active sentences into passive, keep in mind:
- The object of the active sentence becomes the subject of the passive sentence.
- The verb changes form (to be + past participle).
- The subject of the active sentence becomes an optional by-phrase or is omitted.
Passive Voice Examples by Tense

| Simple Past | Ali wrote a letter. | A letter was written by Ali. |
| Present Perfect | Ali has written a letter. | A letter has been written by Ali. |

| Present Progressive | Ali is writing a letter. | A letter is being written by Ali. |
| Past Progressive | Ali was writing a letter. | A letter was being written by Ali. |
| Past Perfect | Ali had written a letter. | A letter had been written by Ali. |

| Conditional I | Ali would write a letter. | A letter would be written by Ali. |
| Conditional II | Ali would have written a letter. | A letter would have been written by Ali. |
Passive with Two Objects
When a sentence has two objects, either object can be the focus.
Active: Ali wrote a letter to me.
Passive Option 1: A letter was written to me by Ali.
Passive Option 2: I was written a letter by Ali.
Note: The by Ali phrase is often omitted if it’s not crucial to the meaning.
Personal and Impersonal Passive
Personal Passive uses the object of the active sentence as the subject of the passive sentence.
Example: They build houses becomes Houses are built.
Impersonal Passive can be used with verbs of perception like say, think, and know.
Example: They say that women live longer than men.
- Impersonal Passive: It is said that women live longer than men.
- Personal Passive: Women are said to live longer than men.
In English, personal passive is generally preferred over impersonal passive.
