Active vs Passive Voice: The Key Difference
In active voice, the subject performs the action. In passive voice, the subject receives the action. Both are correct English, but we use them for different reasons. Active voice is usually clearer and more direct. Passive voice is useful when the action is more important than who does it, or when we don't know or don't want to say who does it.
When to Use Active Voice
Use active voice when you want to be clear about who does the action. Active voice is more direct, energetic, and easier to understand. It's the natural choice for most writing and speaking. Use active voice in reports, instructions, and everyday conversation.
When to Use Passive Voice
Use passive voice when the action or result is more important than who does it. Also use it when you don't know who did the action, or when it's not important to say. Passive voice is common in scientific writing, news reports, and formal announcements.
Quick Tip: How to Choose
Ask yourself: Is it important WHO does the action? If yes, use active voice. If the action itself is more important, or if you don't know who did it, use passive voice. When in doubt, choose active voice—it's usually the better choice.
Active vs Passive Voice: Side-by-Side Comparison
| Dimension | Active Voice | Passive Voice |
|---|---|---|
| Form | Subject + verb + object (The agent performs the action) |
Subject + to be + past participle (+ by + agent) (The receiver of the action becomes the subject) |
| Focus | On the doer of the action — who or what is acting | On the receiver of the action — what is being done |
| When to Use |
• The doer is known and important • You want direct, clear, concise writing • Storytelling or narrative writing • Business communication and everyday writing • When you want to assign responsibility clearly |
• The doer is unknown, unimportant, or obvious • You want to emphasise the action or result • Scientific, academic, or formal writing • When you want to avoid naming who is responsible • Legal or procedural documents |
| Positive Example | The manager approved the budget. | The budget was approved (by the manager). |
| Negative Example | The scientist did not publish the findings. | The findings were not published (by the scientist). |
| Question Example | Did the committee review the proposal? | Was the proposal reviewed (by the committee)? |
| Clarity & Tone | Generally clearer, more direct, and energetic; easier for readers to follow | Can feel more formal or impersonal; may obscure meaning if overused |
| Sentence Length | Typically shorter and more concise | Typically longer due to auxiliary verbs and optional "by" phrase |
| Typical Contexts | Journalism, fiction, emails, blog posts, marketing copy, most everyday communication | Scientific reports, lab write-ups, legal texts, formal notices, policy documents |
| Key Signal Words | Strong action verbs in their base or conjugated form; subject clearly named at the start | is/are/was/were/been/being + past participle; optional by phrase; it is said / it was found / it has been reported |
| Common Pitfall | Can feel blunt or overly personal in contexts that traditionally demand formality | Overuse leads to wordy, evasive, or impersonal prose that buries the real agent |
| 🔑 Key Difference: Active voice puts the doer first, making sentences direct, energetic, and easy to read — ideal for most writing. Passive voice puts the receiver or result first, which is valuable when the doer is unknown, irrelevant, or deliberately omitted, and is especially suited to formal, scientific, or procedural contexts. The best writers use active voice as their default and switch to passive only when it genuinely serves clarity, emphasis, or appropriate tone. | ||

When to use it
News and Reports
Use passive voice when reporting events where the action matters more than the person. This is common in journalism and formal announcements.
"Five people were injured in the accident this morning."
Scientific Writing
Passive voice is standard in science because the experiment or result is the focus, not the scientist doing it.
"The samples were tested at a temperature of 25 degrees."
Everyday Conversation
Use active voice in daily speech and informal writing. It sounds more natural and is easier to understand.
"I bought new shoes yesterday." instead of "New shoes were bought by me yesterday."
When You Don't Know Who
Use passive voice when the person who did the action is unknown or irrelevant to your message.
"My phone was stolen during the concert."

Common Mistakes
✕
Wrong
The cake was eaten by someone yesterday.
✓
Correct
Someone ate the cake yesterday. OR The cake was eaten yesterday.
Don't use passive voice with 'someone'—it sounds awkward. Use active voice or remove the agent.
✕
Wrong
The letter was received by the company last month.
✓
Correct
The company received the letter last month.
When the agent (who does the action) is clear and important, active voice is better and more natural.
✕
Wrong
The decision was made by the team in a meeting.
✓
Correct
The team made the decision in a meeting.
Passive voice with obvious agents adds unnecessary words. Active voice is clearer and more direct.
