What is the Passive Voice?
The passive voice is a grammatical construction where the subject of the sentence is the recipient of an action rather than the doer. In passive sentences, the focus is on the action itself or the object affected by that action.
For example, instead of saying "The chef cooks the meal," in the passive voice you say "The meal is cooked by the chef."
The letter was written by Sarah.
The letter was written by Sarah.
The letter was written by Sarah.
The song is sung by the choir.
The song is sung by the choir.
The song is sung by the choir.
Forming the Passive Voice
The passive voice is formed by combining the verb "to be" with the past participle of the main verb.
The structure is:
| Active Voice | Passive Voice |
|---|---|
| Subject + Verb + Object | Subject (object) + form of "to be" + Past Participle (+ by + agent) |
Active: The teacher explains the lesson.
Active: The teacher explains the lesson.
Active: The teacher explains the lesson.
Passive: The lesson is explained by the teacher.
Passive: The lesson is explained by the teacher.
Passive: The lesson is explained by the teacher.
Passive Voice in Different Tenses
The verb "to be" changes according to the tense, while the past participle of the main verb remains the same. Below is a table showing examples in various tenses using the verb "to write."
| Tense | Passive Form | Example |
|---|---|---|
| Present Simple | am/is/are + written | The book is written by an author. |
| Past Simple | was/were + written | The letter was written yesterday. |
| Future Simple | will be + written | The report will be written tomorrow. |
| Present Perfect | has/have been + written | The emails have been written. |
Using "by" to Show the Agent
In passive sentences, the agent (the doer of the action) is often introduced by the preposition "by." However, the agent can be omitted if it is unknown, unimportant, or obvious from context.
The cake was baked by my mother.
The cake was baked by my mother.
The cake was baked by my mother.
The window was broken.
The window was broken.
The window was broken.
Notice that the second sentence does not mention who broke the window.
Why and When to Use the Passive Voice
The passive voice is useful in several situations:
- When the focus is on the action or the object, not the subject.
- When the doer of the action is unknown or unimportant.
- In formal or scientific writing to emphasize processes or results.
- To be polite or indirect.

Common Errors to Avoid
Here are some frequent mistakes learners make when using the passive voice:
- Using the wrong form of "to be" for the tense.
- Forgetting to use the past participle of the main verb.
- Using passive voice with intransitive verbs (verbs that do not take an object).
- Incorrect word order or omitting important parts.

Incorrect: The book wrote by her.
Incorrect: The book wrote by her.
Correct: The book was written by her.
Correct: The book was written by her.
Correct: The book was written by her.

Tips for Remembering Rules
- Always identify the object of the active sentence; it becomes the subject in the passive.
- Remember to use the correct tense form of "to be" before the past participle.
- Check if the main verb is transitive; passive voice is not possible with intransitive verbs.
- Practice by converting simple sentences first, then move to complex ones.
- Keep in mind that the agent introduced by "by" is optional.
