Passive vs active voice comes down to who does the action. In active voice, the subject does the action: “The chef cooked the meal.” In passive voice, the subject receives it: “The meal was cooked by the chef.”
Use active voice for clear, direct writing, and use passive voice when the doer is unknown or unimportant.
What Is Active Voice?
Active voice puts the doer first. The pattern is subject + verb + object.
Take “Mary baked the cake.” Mary is the doer, “baked” is the action, and the cake receives it. Readers process this order fast, so the sentence feels direct.
Active Voice Examples
- The storm damaged the roof.
- Our team launched the app.
- Students attended the lecture.
- The dog chased the ball.
Each sentence names the doer up front. Nothing is hidden.
What Is Passive Voice?
How Passive Voice Sentences Are Built
Passive voice flips the order. The pattern is object + a form of “be” + past participle, with an optional “by” phrase for the doer.
“The cake was baked by Mary” is passive. Often the doer drops out completely: “The cake was baked.”
Passive Voice Examples
“My car was stolen” is a common one. We don’t know who took it, so the passive fits.
“Your package has been shipped” works the same way. The shipper doesn’t matter to the buyer.
Quick Ways to Spot Passive Voice
Look for a form of “be” (is, was, were, been, being) plus a past participle like “written” or “taken.”
Here is a handy test. Add “by zombies” after the verb. If the sentence still makes sense, it is passive: “The report was reviewed by zombies.”

Passive vs Active Voice
| Feature | Active Voice | Passive Voice |
|---|---|---|
| Subject | Does the action | Receives the action |
| Pattern | Subject + verb + object | Object + be + past participle |
| Doer | Named up front | Hidden or placed after “by” |
| Example | The manager approved the plan. | The plan was approved by the manager. |
| Length | Shorter | Longer |
| Tone | Direct and strong | Formal and impersonal |
Impact on Tone, Clarity, and Word Count
Active voice sounds confident and personal. Passive voice sounds formal and distant.
Both are correct grammar. The real difference is clarity. Passive sentences add words and can leave readers asking, “Who did this?”
When to Choose Active or Passive Voice
Everyday, Blog, and Business Writing
Make active voice your default for emails, blogs, ads, and reports. “We will send the invoice on Friday” beats
The active version shows who owns the task. That builds trust fast.
Academic and Scientific Writing
Passive voice shows up often in lab reports, especially in methods sections. The focus stays on the process, not the researcher.
Many journals now welcome active voice and even “we.” The Oxford guide advises checking a journal’s author instructions first, and it notes that the most readable text often mixes both voices.
When the Doer Is Unknown or Unimportant
- The doer is unknown: “The window was broken overnight.”
- The doer does not matter: “Coffee is grown near the equator.”
- The receiver is the main topic: “Patients were treated within an hour.”
- You want a tactful tone: “A mistake was made in the report.”
- You want to avoid repeating the doer: after naming the team once, say “The plan was approved.”
How to Change Passive Voice to Active Voice
Simple Steps for Passive to Active Conversion
How do you change passive voice to active voice?
- Find the doer, often after “by.”
- Move the doer to the front as the subject.
- Drop the “be” verb and use the main verb in the same tense.
- Place the receiver after the verb.
If no doer appears, add a fitting one like “we” or “the team,” or keep the passive.
Before and After Examples
- Passive: The report was written by the intern.
Active: The intern wrote the report. - Passive: The rules were changed by the board.
Active: The board changed the rules.
Passive Voice Patterns Across Common Tenses
| Tense | Passive | Active |
|---|---|---|
| Present simple | The door is locked by Sam. | Sam locks the door. |
| Present continuous | The door is being locked by Sam. | Sam is locking the door. |
| Past simple | The door was locked by Sam. | Sam locked the door. |
| Present perfect | The door has been locked by Sam. | Sam has locked the door. |
| Future simple | The door will be locked by Sam. | Sam will lock the door. |
In passive sentences, the “be” verb carries the tense. The past participle never changes.
