What Is Voice?
Voice in language determines how the action in a sentence is presented in relation to the subject and the object. It is a crucial tool that impacts the clarity and tone of verbal communication. By choosing different types of voice, speakers can emphasize particular aspects of their message, whether it's the doer of an action or the receiver. This flexibility helps in crafting more engaging and varied expressions in both writing and speaking.
What Are The Types of Voices?
Voices have two types.
Active Voice: In the active voice, the subject of the sentence performs the action. It highlights the doer and makes the sentences direct and dynamic.
For example:
The cat chased the mouse.
The chef cooked a delicious meal.
She sings a beautiful song.
The gardener is planting flowers.
The teacher explained the lesson.
Passive Voice: In the passive voice, the focus shifts to the receiver of the action. The subject of the sentence is acted upon. This voice is useful when the doer is unknown or less important than the action itself.
For example:
The mouse was chased by the cat.
A delicious meal was cooked by the chef.
A beautiful song is sung by her.
Flowers are being planted by the gardener.
The lesson was explained by the teacher.
How to Convert Active Voice to Passive Voice
According to voice grammar rules when converting sentences from active voice to passive voice, it's important to rearrange components and sometimes change the verb form. This makes the subject of the sentence the receiver of the action rather than the doer.
Identify the Subject, Verb, and Object
In active sentences, the format usually follows "Subject-Verb-Object." To form a passive voice, you need to reverse this to "Object-Verb-Subject."
Active: The cat (subject) chased (verb) the mouse (object).
Passive: The mouse (object) was chased (verb) by the cat (subject).
Use the Object as the New Subject
Start the passive sentence with the object of the active sentence. This new subject will receive the action.
Active: A baker (subject) makes (verb) cakes (object).
Passive: Cakes (new subject) are made (verb) by a baker (new agent).
Change the Verb Form
Adjust the verb to include a form of "be" (am, is, are, was, were) followed by the past participle of the main verb. The correct form of "be" depends on the tense of the original verb.
Active: She (subject) writes (verb) emails (object).
Passive: Emails (new subject) are written (new verb form) by her (new agent).
Add 'by' Before the Original Subject
In passive voice, the original doer of the action (the subject in active voice) usually follows the word "by."
Active: The gardener (subject) is planting (verb) flowers (object).
Passive: Flowers (new subject) are being planted (new verb form) by the gardener (new agent).
Adjust for Tense
The form of "be" used must match the tense of the active sentence. Here are examples for different tenses:
Simple Present Tense
In the simple present, use "is" or "are" depending on the number (singular or plural) of the new subject (object of the active sentence).
Active: The chef cooks the meal.
Passive: The meal is cooked by the chef.
Simple Past Tense
In the simple past, use "was" or "were" based on the new subject's number.
Active: The chef cooked the meal.
Passive: The meal was cooked by the chef.
Present Continuous Tense
For the present continuous, use "is being" or "are being" depending on the new subject's number.
Active: The chef is cooking the meal.
Passive: The meal is being cooked by the chef.
Past Continuous Tense
In the past continuous, use "was being" or "were being" to reflect the number of the new subject.
Active: The chef was cooking the meal.
Passive: The meal was being cooked by the chef.
Future Simple Tense
For the future simple, use "will be" regardless of the new subject's number.
Active: The chef will cook the meal.
Passive: The meal will be cooked by the chef.
Present Perfect Tense
In the present perfect, use "has been" or "have been" depending on the new subject's number.
Active: The chef has cooked the meal.
Passive: The meal has been cooked by the chef.
Past Perfect Tense
For the past perfect, use "had been" for all subjects.
Active: The chef had cooked the meal.
Passive: The meal had been cooked by the chef.
Future Perfect Tense
In the future perfect, use "will have been" regardless of the new subject's number.
Active: The chef will have cooked the meal.
Passive: The meal will have been cooked by the chef.
Modal Verbs (can, may, must, should, etc.)
With modals, use "[modal] be" (can be, may be, must be, should be, etc.), which doesn't change with the subject's number.
Active: The chef can cook the meal.
Passive: The meal can be cooked by the chef.
Infinitive Structures
For infinitive structures, "to be" is added following the infinitive marker "to."
Active: The chef wants to cook the meal.
Passive: The meal is wanted to be cooked by the chef.
Make Necessary Pronoun Adjustments
If the sentence has pronouns, you may need to change them to make sense in passive voice (e.g., her to she, them to they).
Active: He (subject) loves (verb) her (object).
Passive: She (new subject) is loved (new verb form) by him (new agent).
Omit the Doer
If the doer of the action is not important or unknown, you can leave it out in the passive sentence.
Active: Someone (subject) stole (verb) my wallet (object).
Passive: My wallet (new subject) was stolen (new verb form).
How to Convert Passive Voice to Active Voice
When converting sentences from passive voice to active voice, it's important to rearrange components and sometimes change the verb form.
Identify the Subject, Verb, and Object
In passive sentences, the format usually follows "Object being acted upon (Subject)-form of 'be' + past participle (Verb)-by Agent (Object)."
To form an active voice, you need to reverse this to "Agent (Subject)-main verb (Verb)-Object being acted upon (Object)."
Passive: The meal (subject) was cooked (verb) by the chef (object).
Active: The chef (subject) cooked (verb) the meal (object).
Use the Agent as the New Subject
Start the active sentence with the agent (doer) of the passive sentence. This new subject will perform the action.
Passive: The homework (subject) was completed (verb) by the student (object).
Active: The student (new subject) completed (verb) the homework (object).
Change the Verb Form
Convert the verb to its base form if the passive sentence includes a simple form of "be" (is, are, was, were) followed by the past participle. Adjust according to the tense.
Passive: The song (subject) is sung (verb) by her (object).
Active: She (subject) sings (verb) the song (object).
Remove 'by' and Rearrange the Object
In active voice, the original agent of the action directly follows the verb and there is no "by."
Passive: A novel (subject) was written (verb) by the author (object).
Active: The author (subject) wrote (verb) the novel (object).
Adjust for Tense
Convert the verb to the appropriate tense used in the passive sentence without the auxiliary 'be'.
Simple Present Tense
In the simple present, convert "is/are cooked" to "cooks/cook" depending on the original agent's number (singular or plural).
Passive: The meal is cooked by the chef.
Active: The chef cooks the meal.
Simple Past Tense
In the simple past, change "was/were cooked" to "cooked."
Passive: The meal was cooked by the chef.
Active: The chef cooked the meal.
Present Continuous Tense
For the present continuous, transform "is/are being cooked" to "is/are cooking."
Passive: The meal is being cooked by the chef.
Active: The chef is cooking the meal.
Past Continuous Tense
In the past continuous, adjust "was/were being cooked" to "was/were cooking."
Passive: The meal was being cooked by the chef.
Active: The chef was cooking the meal.
Future Simple Tense
For the future simple, switch "will be cooked" to "will cook."
Passive: The meal will be cooked by the chef.
Active: The chef will cook the meal.
Present Perfect Tense
In the present perfect, modify "has/have been cooked" to "has/have cooked."
Passive: The meal has been cooked by the chef.
Active: The chef has cooked the meal.
Past Perfect Tense
For the past perfect, change "had been cooked" to "had cooked."
Passive: The meal had been cooked by the chef.
Active: The chef had cooked the meal.
Future Perfect Tense
In the future perfect, update "will have been cooked" to "will have cooked."
Passive: The meal will have been cooked by the chef.
Active: The chef will have cooked the meal.
Modal Verbs (can, may, must, should, etc.)
With modals, convert "[modal] be cooked" (can be, may be, must be, should be, etc.) to "[modal] cook."
Passive: The meal can be cooked by the chef.
Active: The chef can cook the meal.
Infinitive Structures
For infinitive structures, revise "is wanted to be cooked" to "wants to cook."
Passive: The meal is wanted to be cooked by the chef.
Active: The chef wants to cook the meal.
Make Necessary Pronoun Adjustments
Adjust pronouns to suit the new subject or object position and ensure they make grammatical sense.
Passive: The car was driven by her.

Include the Doer
Ensure that the doer of the action is clearly mentioned as the subject, unless originally unspecified in passive voice.
