Definition of Active and Passive Voice
The voice of a verb describes the relationship between the action (verb) and the participants (subject and object). In English, there are two main voices: active and passive. Understanding these voices is fundamental to constructing grammatically correct and stylistically appropriate sentences.
Active Voice
In the active voice, the subject performs the action expressed by the verb. This means the subject is the agent or doer of the action. Active voice sentences are generally more direct, clear, and concise.
For example:
- The dog chased the ball.
- She wrote a letter.
- They are building a house.
In each of these sentences, the subject (dog, she, they) is actively performing the action (chased, wrote, are building).
Passive Voice
In the passive voice, the subject receives the action expressed by the verb. The subject is the recipient of the action, not the performer. The agent (the doer of the action) may be included in the sentence, but it is often omitted.
For example:
- The ball was chased by the dog.
- A letter was written by her.
- A house is being built by them.
In these passive voice sentences, the subject (ball, letter, house) is receiving the action. The agent (dog, her, them) is still present but less emphasized.
Structural Breakdown
Understanding the structure of active and passive voice sentences is essential for correctly identifying and using them.
Active Voice Structure
The basic structure of an active voice sentence is:
Subject + Verb + (Object)
The object is optional, depending on whether the verb is transitive (takes an object) or intransitive (does not take an object).
Examples:
- John reads books. (Subject + Verb + Object)
- Birds fly. (Subject + Verb)
Passive Voice Structure
The basic structure of a passive voice sentence is:
Subject + Auxiliary Verb (be) + Past Participle + (by + Agent)
The auxiliary verb “be” changes depending on the tense. The “by + Agent” phrase is optional.
Examples:
- The book was written by Jane. (Subject + Auxiliary Verb + Past Participle + by + Agent)
- The window was broken. (Subject + Auxiliary Verb + Past Participle)
Formation of the Passive Voice
To form the passive voice, you need to:
- Identify the object in the active sentence. This becomes the subject of the passive sentence.
- Use the correct form of the auxiliary verb “be” according to the tense of the active verb.
- Use the past participle of the main verb.
- Add “by + agent” if you want to specify who or what performed the action (optional).
Here’s a table showing how to form the passive voice in different tenses:
| Tense | Active Voice | Passive Voice |
|---|---|---|
| Present Simple | She writes a letter. | A letter is written by her. |
| Past Simple | She wrote a letter. | A letter was written by her. |
| Present Continuous | She is writing a letter. | A letter is being written by her. |
| Past Continuous | She was writing a letter. | A letter was being written by her. |
| Present Perfect | She has written a letter. | A letter has been written by her. |
| Past Perfect | She had written a letter. | A letter had been written by her. |
| Future Simple (will) | She will write a letter. | A letter will be written by her. |
| Future Simple (going to) | She is going to write a letter. | A letter is going to be written by her. |
| Modal Verbs (can, should, etc.) | She can write a letter. | A letter can be written by her. |
This table illustrates how the auxiliary verb “be” changes to reflect the tense of the active verb when forming the passive voice.
Types and Categories of Passive Voice
While the basic structure of the passive voice remains the same, there are different types and categories that are important to recognize.
Agented Passive
The agented passive voice explicitly mentions the agent (the doer of the action) using the preposition “by.” This is used when it’s important to know who or what performed the action.
Example:
- The picture was painted by Van Gogh.
Agentless Passive
The agentless passive voice does not mention the agent. This is used when the agent is unknown, unimportant, obvious, or when you want to avoid mentioning the agent.
Example:
- The window was broken. (The agent is unknown or unimportant)
The ‘Get’ Passive
The “get” passive uses the verb “get” instead of “be” as the auxiliary verb. It often implies a sense of accident, change, or becoming.
It is more informal than the “be” passive.
Example:
- He got injured in the accident.
Pseudo-Passive Verbs
Some verbs, when used in the passive voice, can create structures that resemble the passive voice but function differently. These are sometimes called pseudo-passive verbs.
They often involve verbs of perception, knowing, or feeling.
Example:
- He is known to be a liar.
In this case, “is known” looks passive, but it functions more like an adjective describing “He.”
Examples of Active and Passive Voice
Here are several examples to illustrate the differences and variations in active and passive voice.
Active Voice Examples
The following table provides a comprehensive list of active voice examples across various tenses.
| Tense | Example |

Usage Rules for Active and Passive Voice
Choosing between the active and passive voice depends on the context and the desired emphasis.
When to Use Active Voice
Use the active voice when:
- You want to emphasize the actor or the doer of the action.
- You want to make your writing more direct, clear, and concise.
- You want to create a more engaging and dynamic tone.
- The actor is known and relevant to the sentence.
Examples:
- The chef cooked a delicious meal. (Emphasizes the chef’s skill)
- The company launched a new product. (Highlights the company’s action)
When to Use Passive Voice
Use the passive voice when:
- You want to emphasize the action or the recipient of the action rather than the doer.
- The actor is unknown, unimportant, or obvious.
- You want to avoid assigning blame or responsibility.
- You want to maintain a formal or objective tone, especially in scientific or technical writing.
Examples:
- The experiment was conducted in a controlled environment. (Focuses on the experiment)
- The mistake was made. (Avoids assigning blame)
When to Avoid Passive Voice
Avoid overusing the passive voice, as it can make your writing:
- Vague and indirect.
- Wordy and cumbersome.
- Less engaging and less interesting.
In general, prefer the active voice unless there’s a specific reason to use the passive voice.
Common Mistakes
Several common mistakes can occur when using the active and passive voice.
Misusing the Passive Voice
Using the passive voice when the active voice would be clearer and more direct is a common mistake. This can lead to awkward and confusing sentences.
Incorrect: The report was written by me.
Correct: I wrote the report.
Incorrect Passive Formation
Failing to use the correct form of the auxiliary verb “be” or the past participle can lead to grammatically incorrect passive sentences.
Incorrect: The letter is write by her.
Correct: The letter is written by her.
Unnecessary Use of Passive Voice
Using the passive voice when the agent is known and important can obscure the meaning and make the sentence less impactful.
Incorrect: The ball was kicked.
Correct: John kicked the ball. (If John is relevant to the sentence)

Advanced Topics
For advanced learners, there are more complex aspects of the passive voice.
Passive Voice in Reporting Verbs
The passive voice is often used with reporting verbs (e.g., say, believe, think) to express opinions or beliefs without explicitly stating who holds those opinions.
Example:
- It is said that he is a talented musician.
Impersonal Passive Constructions
Impersonal passive constructions involve a dummy subject (“it”) and a passive verb, often used to express general truths or opinions.
Example:
- It is believed that the Earth is round.
Passive Voice in Cleft Sentences
Cleft sentences using the passive voice can be used to emphasize a particular element of a sentence.
Example:
- It was the book that was written by her that won the award.
Frequently Asked Questions (FAQ)
Here are some frequently asked questions about the active and passive voice.
- What is the difference between active and passive voice?
In the active voice, the subject performs the action (e.g., “The dog chased the ball”). In the passive voice, the subject receives the action (e.g., “The ball was chased by the dog”).
- When should I use the passive voice?
Use the passive voice when you want to emphasize the action or the recipient of the action, when the actor is unknown or unimportant, or when you want to avoid assigning blame.
- How do I form the passive voice?
The passive voice is formed using the auxiliary verb “be” (in the appropriate tense) + the past participle of the main verb (e.g., “is written,” “was built,” “has been seen”).
- Is it always better to use the active voice?
Not always. While the active voice is generally more direct and concise, the passive voice is appropriate in certain situations where the action or the recipient is more important than the actor.
- What is an agentless passive?
An agentless passive is a passive voice sentence that does not mention the agent (the doer of the action). This is used when the agent is unknown, unimportant, or obvious (e.g., “The window was broken”).
-
Can the passive voice be used in all tenses?
Yes, the passive voice can be used in most tenses. However, it’s less common in continuous tenses and perfect continuous tenses due to the complexity of the verb forms.
- What are some common reporting verbs used in the passive voice?
Common reporting verbs include “say,” “believe,” “think,” “report,” “claim,” and “know” (e.g., “It is said that…”).
- How can I identify the voice of a sentence quickly?
Look at the subject of the sentence. If the subject is performing the action, it’s active. If the subject is receiving the action, it’s passive.
- Is the “get” passive as grammatically correct as the “be” passive?
The “get” passive is grammatically correct, but it is generally considered more informal than the “be” passive. It is often used in spoken English and informal writing.
- Are there any verbs that cannot be used in the passive voice?
Intransitive verbs (verbs that do not take an object) cannot be used in the passive voice (e.g., “sleep,” “arrive,” “die”).
Conclusion
Mastering the active and passive voice is essential for effective communication in English. By understanding the definitions, structural breakdowns, types, examples, usage rules, and common mistakes associated with each voice, you can significantly improve your writing and speaking skills.
Remember to choose the voice that best suits your purpose and audience, and avoid overusing the passive voice to maintain clarity and engagement in your communication. With practice and careful attention, you can confidently use both the active and passive voice to express your ideas with precision and impact.
