What is Active Voice?
Active voice is a grammatical structure where the subject of the sentence performs the action expressed by the verb. In these sentences, the focus is on the subject doing something.
Structure of Active Voice
The typical structure of an active voice sentence follows this pattern:
- Subject + Verb + Object
For example: - “The cat (subject) chased (verb) the mouse (object).”
Characteristics of Active Voice
- Clarity: Active voice sentences are usually clearer and more direct.
- Engagement: They tend to be more engaging for readers or listeners.
- Dynamic Tone: The action is emphasized, making the writing feel more lively.
What is Passive Voice?
Passive voice, on the other hand, is a grammatical structure where the subject of the sentence receives the action expressed by the verb rather than performing it. In passive constructions, the focus shifts from who is doing the action to what is being acted upon.
Structure of Passive Voice
The typical structure of a passive voice sentence follows this pattern:
- Object + Form of “to be” + Past Participle + (by Subject)
For example: - “The mouse (object) was chased (past participle) by the cat (subject).”
Characteristics of Passive Voice
- Focus on Action: The action itself takes precedence over who performed it.
- Formality: Passive voice can sound more formal or impersonal.
- Ambiguity: It can sometimes obscure who is responsible for an action.
Key Differences Between Active and Passive Voice
| Feature | Active Voice | Passive Voice |
|---|---|---|
| Subject Role | Performs the action | Receives the action |
| Sentence Structure | Subject + Verb + Object | Object + Form of “to be” + Past Participle + (by Subject) |
| Clarity | Generally clearer | Can be less clear |
| Engagement | More engaging | Often less engaging |
| Use in Writing | Preferred for most writing styles | Useful in specific contexts |
When to Use Active Voice
Active voice is preferred in most writing situations due to its clarity and directness. Here are some scenarios where active voice shines:
- Creative Writing: Engaging storytelling often relies on active constructions to create vivid imagery.
- Business Communication: Clear directives and reports benefit from active voice for straightforward understanding.
- Academic Writing: While some academic contexts may use passive voice, active constructions help convey arguments more effectively.
Examples:
- “The researcher conducted experiments.”
- “The team completed the project ahead of schedule.”
When to Use Passive Voice
While active voice is generally preferred, there are specific situations where passive voice is more appropriate:
- Emphasis on Action: When the action itself is more important than who performed it.
- Unknown Agent: When the doer of the action is unknown or irrelevant.
- Formal Writing: In scientific or technical writing where objectivity is key.
Examples:
- “The results were published in a prestigious journal.” (Focus on results)
- “A mistake was made.” (Unknown agent)
How to Convert Active Voice to Passive Voice
Converting a sentence from active to passive involves several steps:
- Identify the object of the active sentence.
- Move the object to the front as the new subject.
- Change the verb into its passive form using an appropriate form of “to be.”
- Add the original subject at the end with “by,” if necessary.
Example Conversion:
Active: “The chef prepared a delicious meal.”
Passive: “A delicious meal was prepared by the chef.”

Understanding common pitfalls can help writers avoid confusion:
- Overusing Passive Voice: Many writers fall into a habit of using passive constructions excessively, leading to dull writing.
