Passive Voice in English Grammar
What is the passive voice?
The passive voice in English grammar allows us to make the recipient of the action the focus of the sentence; the person or thing performing the action is unknown, unimportant or obvious. The passive is formed as follows: form of be + past participle.

My bike was stolen last night.
The cellar in our building was broken into and several bikes were taken.
I called the police earlier, but they had already been informed by my neighbour.
An investigation is being conducted, but the thief has not been arrested yet.
Any information should be reported to the police.
When to use the passive in English grammar
Active sentences usually follow the subject-verb-object word order and focus on the person or thing performing the action.
- A criminal stole my bike.
In contrast, the passive voice focuses on the action itself. Passive sentences tell us what happens to the recipient of the action.
- My bike was stolen.
We use the passive when the person or thing performing the action (known as the agent) is unknown, unimportant or obvious.
- My bike was stolen. → unknown agent
- An investigation is being conducted. → obvious agent (the police)
- A mistake has been made. → avoids naming the agent
- Any information should be reported to the police. → people in general
If we want to include the agent of a passive sentence, we use the preposition by.
- My bike was stolen by a criminal.
- They had already been informed by my neighbour.
How to form the passive in English grammar
Passive sentences are formed as follows: form of be + past participle of the main verb.
Only the form of the verb be changes depending on the tense that we are using; the past participle remains the same in every tense.
The table below provides an overview of the passive voice in all of the English tenses.
|Simple Present||The thief is arrested.|
|Present Progressive||The thief is being arrested.|
|Present Perfect||The thief has been arrested.|
|Simple Past||The thief was arrested.|
|Past Progressive||The thief was being arrested.|
|Past Perfect||The thief had been arrested.|
|Will Future||The thief will be arrested.|
|Future with going to||The thief is going to be arrested.|
|Future Perfect||The thief will have been arrested.|
|Infinitive||The thief should be arrested.
The thief would be arrested.
|Perfect Infinitive||The thief should have been arrested.
The thief would have been arrested.
How to change a sentence from active to passive
When transforming a sentence from active to passive, we can take a step-by-step approach.
- Step 1: identify the object of the sentence and bring it to the front
- Someone stole my bike.
- My bike …
- Step 2: identify the tense and conjugate the verb be accordingly
- Someone stole my bike. = simple past
- My bike was …
- Step 3: find the past participle of the main verb
- Someone stole my bike. → steal – stole – stolen
- My bike was stolen.
- Step 4: decide if you need to include the agent
- Someone stole my bike. → Who stole the bike? We don’t know.
- The agent is unknown and therefore unnecessary in this case.
- Step 5: if the agent is important, we introduce it using the preposition by.
- A cyclist caused the crash.
- The crash was caused by a cyclist.
- This sentence does not make sense without the agent.
Because the direct object of the active sentence becomes the subject of the passive sentence, we can only use transitive verbs in the passive voice (e.g., steal a car, write a book, make a mistake …). Intransitive verbs do not take a direct object (e.g., arrive, die, go …) so cannot be used in the passive.

The passive in sentences with two objects
Certain verbs like ask, give, offer, pay, send, show etc. are used with two objects. Usually, one is a person (indirect object) and the other is a thing (direct object).
In the active voice, these sentences can be expressed in two different ways:
- Someone gave Josie this calendar.
- Someone gave this calendar to Josie.
- indirect object (IO): Josie; direct object (DO): this calendar
This is the same in the passive voice; either object can become the subject of the passive sentence.
- Josie was given this calendar.
- indirect object (Josie) → subject (Josie)
- This calendar was given to Josie.
- direct object (this calendar) → subject (this calendar)
Changing object pronouns to subject pronouns
When the indirect object of an active sentence is an object pronoun (me, you, him, her …), we must change it to a subject pronoun in the passive voice.
|Active Voice||Object Pronoun||Subject Pronoun||Passive Voice|
|They told me about the crime.||me||I||I was told about the crime.|
|They told you about the crime.||you||you||You were told about the crime.|
|They told her about the crime.||her||she||She was told about the crime.|
|They told him about the crime.||him||he||He was told about the crime.|
|They reported it to the police.||it||it||It was reported to the police.|
|They told us about the crime.||us||we||We were told about the crime.|
|They told them about the crime.||them||they||They were told about the crime.|
Personal & Impersonal Passive
In formal situations such as news reports or academic articles, we use reporting verbs and verbs of speech and thought in the passive voice to express information in a neutral, unbiased way.
Common verbs: agree, announce, assume, believe, claim, consider, declare, expect, feel, find, know, mention, say, suppose, think, and understand.
Such sentences can start with it (impersonal passive) or with the subject (personal passive).
- It is said that this area has a high crime rate. (impersonal passive)
- This area is said to have a high crime rate. (personal passive)
- = They say that this area has a high crime rate.
Sentences in the impersonal passive begin with it: it is said/believed/agreed etc. + that + clause.
- It is believed that the suspect has blonde hair.
- It is said that the neighbourhood is a hotspot for crime.
- It is assumed that the thief is local to the area.
Note: in the impersonal form, only the reporting verb is formed in the passive voice; the rest of the sentence stays the same.
Sentences in the personal passive begin with the subject and contain an infinitive clause: subject + is said/believed/thought etc. + to + infinitive.
- The suspect is believed to have blonde hair.
- The neighbourhood is said to be a hotspot for crime.
- The thief is assumed to be local to the area.
We use the perfect infinitive (have + past participle) after the reporting verb to refer to the past.
- The theft is believed to have occurred at midnight last night.
- The thief is said to have acted alone.
