Active vs Passive Voice: When to Use Which
Published: May 18, 2026 · 8 min read
Every sentence has a "voice" — the relationship between the subject performing the action and the subject receiving it. Understanding the difference between active and passive voice is one of the fastest ways to improve your writing clarity, impact, and readability.
What Is Active Voice?
In active voice, the subject performs the action of the verb. The structure is straightforward: Subject → Verb → Object.
Examples:
- The marketing team launched the campaign. (Team → launched → campaign)
- The chef prepared a five-course meal. (Chef → prepared → meal)
- Our developer fixed the bug in two hours. (Developer → fixed → bug)
Active voice is direct, concise, and easy to visualize. The reader knows immediately who did what.
What Is Passive Voice?
In passive voice, the subject receives the action. The object becomes the focus, and the doer either appears later (after "by") or is omitted entirely. Structure: Object → form of "be" + past participle → (by Subject).
Examples:
- The campaign was launched by the marketing team.
- A five-course meal was prepared by the chef.
- The bug was fixed in two hours. (doer omitted)
Notice how passive voice adds words — "was" plus the past participle — and often requires a "by" phrase to identify who did the action. When the doer is omitted, the sentence becomes vague.
Side-by-Side Comparison
| Active | Passive |
|---|---|
| The board approved the budget. | The budget was approved by the board. |
| The storm damaged three homes. | Three homes were damaged by the storm. |
| She wrote the report in one day. | The report was written in one day. |
| Researchers discovered a new treatment. | A new treatment was discovered. |
In each pair, the active version is shorter and clearer. The passive version is longer and — when the doer is removed — leaves the reader wondering who acted.
When to Use Active Voice
Active voice should be your default choice for most writing. It works best when you want:
- Clarity: The reader immediately knows who is responsible. "The manager approved your request" is clearer than "Your request has been approved."
- Conciseness: Active sentences use fewer words. Every unnecessary word dilutes your message.
- Impact: Direct statements carry more weight. "We will reduce costs" feels more decisive than "Costs will be reduced."
- Engagement: Active voice keeps readers moving through your text. Passive voice slows reading speed.
In business communication, journalism, marketing, and creative writing, active voice is almost always the right choice. A study of professional writing found that 90-95% of sentences in well-edited publications use active voice.
When to Use Passive Voice
Passive voice is not wrong — it is a tool. Use it deliberately in these situations:
1. The Doer Is Unknown or Unimportant
Example: "My bicycle was stolen last night." (You do not know who stole it.)
Example: "The windows are cleaned every Monday." (Who cleans them is irrelevant.)
2. The Action or Result Is More Important Than the Actor
Example: "Your application has been approved." (The decision matters, not who made it.)
Example: "A vaccine was developed in record time." (The achievement is the focus.)
3. Scientific and Academic Writing
Many fields prefer passive voice in methodology sections to keep the focus on the process, not the researcher. "The samples were heated to 100°C and analyzed." This convention is fading in favor of active voice ("We heated the samples..."), but passive remains common in formal journals.
4. Tact or Diplomacy
Passive voice can soften blame or criticism. "The deadline was missed" is less confrontational than "You missed the deadline." Use this sparingly — overusing passive to avoid responsibility damages trust.
Common Myths About Passive Voice
Myth 1: "Never use passive voice."
This is poor advice. Professional writers use passive voice strategically. The goal is not to eliminate it but to choose when to use it.
Myth 2: "Any sentence with 'was' or 'were' is passive."
No. "The sky was blue" uses a linking verb (was) with an adjective — not passive voice. Passive voice requires a past participle and must show the subject receiving an action.
Myth 3: "Grammar checkers always flag passive voice."
Most tools flag passive constructions, but they cannot judge intent. Use your own judgment about whether passive voice serves your purpose.
Quick Test: Is This Sentence Passive?
- Find the verb. Does it include a form of "be" (is, am, are, was, were, been, being) plus a past participle?
- Ask: Is the subject performing the verb or receiving it?
- Can you add "by zombies" after the verb? If it makes grammatical sense, the sentence is passive.
Example: "The cake was eaten." → The cake was eaten (by zombies). Yes — passive.
Example: "The cake was delicious." → The cake was delicious (by zombies). No — this is not passive, it is describing a state.
Rewrite This: Passive → Active
Try converting these passive sentences to active:
- "The meeting was led by Sarah." → "Sarah led the meeting."
- "Mistakes were made." → "We made mistakes." (honest and direct)
- "It has been decided that the office will be closed." → "Management decided to close the office."
- "The email was sent to all employees." → "HR sent the email to all employees."
