Active and passive voice describe the same idea from two directions: the active voice puts the doer first, and the passive voice puts the receiver first. The active version, as in the chef cooked the meal, is shorter and easier to read.
Active and passive voice at a glance
- The active voice puts the doer first: The chef cooked the meal.
- The passive voice puts the receiver first: The meal was cooked by the chef.
- Active sentences are usually shorter and easier to read.
- The passive is built from be plus a past participle.
- Passive voice suits news and science when the doer is unknown or unimportant.
- Only transitive verbs with an object can become passive.
What is the difference between active and passive voice?
The difference lies in which noun leads. In the active voice the doer is the subject and the verb acts on an object; in the passive voice the object moves to the front and the doer drops to a by phrase or disappears. The same event keeps its meaning while the focus shifts.
| Voice | Who leads | Example |
|---|---|---|
| Active | The doer leads the sentence | The gardener watered the plants. |
| Passive | The receiver leads the sentence | The plants were watered by the gardener. |
| Passive without a doer | No doer is named | The plants were watered. |
| Passive question | The receiver leads, in question form | Were the plants watered? |
| Passive with a modal | A rule or duty is stated | The plants must be watered. |

How do you change active voice into passive voice?
The change follows three steps: move the object to the front, add the right form of be, then put the main verb into its past participle. If the doer still matters, keep it in a by phrase, and if it does not, drop it.
| Pattern | Example | What it signals |
|---|---|---|
| doer + verb + object | The manager signed the form. | The active voice, doer first. |
| object + be + participle | The form was signed by the manager. | The passive voice, receiver first. |
| be + participle, no doer | The form was signed. | The doer is unknown or irrelevant. |
| modal + be + participle | The form must be signed. | The passive is used with a modal. |
| have been + participle | The form has been signed. | The perfect passive marks a finished action. |
A set of passive sentences shows how often the doer can be dropped.
Active and passive voice across contexts
Each row shows where one voice beats the other. The final column explains the choice. To watch the passive build up in a single line, compare active sentences with passive sentences.
| Context | Example sentence | Why this works |
|---|---|---|
| Work email | The report was approved by the board. | The passive keeps the focus on the report. |
| News report | Three homes were damaged by the storm. | The passive highlights the damage, not the storm. |
| Science writing | The sample was heated to 90 degrees. | The method matters more than the scientist. |
| Story | The dog chased the cat. | The active voice gives a lively, clear action. |
| Instructions | Remove the cover before use. | The active imperative is direct for the reader. |
| Academic writing | The data were collected over six weeks. | The passive is common in methods sections. |
| Conversation | I lost my keys. | The active voice is natural and short. |
| Meeting notes | A decision was reached after the vote. | The passive masks who decided. |
| Legal writing | The notice must be served in writing. | The passive states the rule impersonally. |
| Customer email | Your parcel was dispatched today. | The passive keeps the customer in focus. |
| Sports report | The keeper saved the penalty. | The active voice names the hero and the action. |
The same word passive appears in passive resistance, where it means non-violent opposition.
When to use active voice and passive voice
Neither voice is correct in every sentence. The active voice suits clear everyday writing, while the passive helps when the doer is unknown, obvious or better left unnamed, so the choice depends on what the reader needs to see first.
| Situation | Better choice | Why |
|---|---|---|
| Everyday writing | Active | Shorter and clearer |
| Unknown doer | Passive | No doer can be named |
| News headline style | Active | Direct verbs read better |
| Scientific method | Passive | Focus falls on the process |
| Blame avoidance | Passive, used carefully | It hides the doer, which can seem evasive |
| Emphasis on the receiver | Passive | The receiver becomes the subject |
Forms and grammar of both voices
The passive exists in every tense, and each one adds the right form of be before the participle. The table uses the verb water so the pattern is easy to see, and the final row shows the active continuous for contrast.
| Form | Part of speech | Example |
|---|---|---|
| water | verb, base, active | The nurse waters the plants. |
| was watered | verb, passive past | The plants were watered. |
| is watered | verb, passive present | The plants are watered daily. |
| has been watered | verb, passive perfect | The plants have been watered. |
| will be watered | verb, passive future | The plants will be watered tomorrow. |
| is watering | verb, active continuous | The nurse is watering the plants. |
Descriptive labels such as adjectives for active help when a sentence needs a different part of speech.
Choosing a voice is an editing decision rather than a grammatical one, because both versions are correct. The active voice suits most sentences, since it is shorter and names who acted, while the passive earns its place when the doer is unknown, obvious or better left unnamed, as in a formal notice. One test helps: if the by phrase adds nothing, drop it and let the receiver lead. Overusing the passive is the common failure, because a page of doerless sentences reads as vague and can seem to dodge responsibility, which is why news editors often rewrite a passive opening into an active one. Read the paragraph aloud and keep the passive only where it earns its keep.

Answers
- The report was written by the team, because the object moves first and be is added.
- The boys broke the window, because the doer returns to the subject position.
- was sent, because the past passive uses was plus the participle sent.
- The song was sung by the choir, because sing has the participle sung.
- The bridge was built in a single summer, because the receiver leads and the doer is dropped.
- (b) The sample was heated, because the passive keeps the method in focus.
The bottom line
Active and passive voice are two ways to arrange the same sentence, and the choice depends on what the reader should notice first. Use the active voice for clear everyday writing and the passive when the doer is unknown or unimportant. Whichever you pick, keep be with a past participle whenever you build a passive.
Frequently asked questions about active and passive voice
Is passive voice always wrong?
No. The passive is the better choice when the doer is unknown, obvious or better left unnamed, as in the sample was heated. Style guides warn against overuse, not against the passive itself, so the question is whether the sentence works.
How do I spot passive voice in a sentence?
Look for a form of be followed by a past participle, as in was written or has been signed. If the doer then appears in a by phrase, or is missing altogether, the sentence is passive. Without a be plus participle pair, it is active.
Can every sentence be made passive?
No. Only a transitive verb, one that takes an object, can form a passive. Intransitive verbs such as happen, sleep and arrive have no object to move to the front, so they cannot be turned into the passive at all.
How much passive voice is too much?
There is no fixed number, but a page where most sentences hide the doer reads as vague or evasive. Aim for active voice as the default and reach for the passive only when the receiver, the process or the unknown doer genuinely deserves the spotlight.
