Active and passive voice show how the subject of a sentence relates to the action. This cheat sheet helps students identify who is doing the action and decide which voice makes a sentence clearer. Students need this skill for essays, narratives, reports, and revision because voice affects clarity, emphasis, and style.
Understanding voice also helps writers avoid wordy or confusing sentences.
In active voice, the subject performs the action, as in The student solved the problem. In passive voice, the subject receives the action, as in The problem was solved by the student. Passive voice often uses a form of be plus a past participle, but not every sentence with be is passive.
Strong writers choose active voice for directness and passive voice when the receiver of the action matters more than the doer.
Key Facts
- Active voice follows the pattern subject + action verb + object, as in The coach praised the team.
- Passive voice often follows the pattern receiver + form of be + past participle + by + doer, as in The team was praised by the coach.
- The subject in active voice does the action, while the subject in passive voice receives the action.
- Common forms of be include am, is, are, was, were, be, being, and been.
- A past participle is often the verb form used in passive voice, such as written, chosen, built, seen, or completed.
- To change passive voice to active voice, move the doer into the subject position and use a clear action verb.
- Use active voice when you want writing to sound clear, direct, and energetic.
- Use passive voice when the doer is unknown, unimportant, or less important than the action or result.

Common Mistakes to Avoid
- Calling every sentence with is or was passive is wrong because some be verbs describe a state, as in The door is red.
- Forgetting to identify the doer is a mistake because active voice depends on knowing who or what performs the action.
- Leaving a passive sentence wordy is a problem because phrases like was completed by can often become a stronger active verb.
- Changing the meaning while revising is wrong because active and passive versions should keep the same basic action and participants.
- Using passive voice in every formal sentence is a mistake because formal writing can still be clear, direct, and active.
