In an active sentence, the subject does the action. In a passive sentence, the subject receives the action instead. Passive voice isn't grammatically wrong, but it usually makes a sentence longer and less direct than it needs to be.

Two labels help before you rewrite anything. The agent is whoever performs the action, and the receiver is whatever the action lands on. In "Sarah wrote the report," Sarah is the agent. Voice is only a question of which one sits in the subject slot, and swapping them is the whole rewrite.

How to spot passive voice

Look for a form of "to be" (is, was, were, been) followed by a past participle, often with "by" introducing who did the action.

The quickest test is the "by" phrase. If you can add "by someone" to the end and the sentence still makes sense, it is probably passive, and the actor is recoverable. "The invoice was approved" becomes "The invoice was approved by the finance team," which hands you the active version almost complete.

Passive: "The report was written by Sarah."
Active: "Sarah wrote the report."

Watch for longer verb strings too. "Is being reviewed," "has been approved," and "will be sent" are all passive even though they do not match the simple "was written" shape. The giveaway is the same every time: a form of "be" plus a participle, with the actor either after "by" or missing.

Why active usually reads better

The active version is shorter, four words instead of six, and puts the person doing the action right at the start. Passive voice buries the actor at the end of the sentence, or drops them entirely.

Passive, no actor: "Mistakes were made."
Active: "I made mistakes." or "The team made mistakes."

Notice the passive version doesn't even say who. That's part of why passive voice is common in situations where the writer wants to avoid assigning responsibility, which is worth being aware of both when writing and when reading.

There is a reading-effort argument as well. An active sentence presents the actor and the action in the order they happen, so the reader builds the picture once. A passive sentence names the receiver first, then asks the reader to hold it in mind while the verb and the actor arrive. That reordering is invisible in a single sentence and quite noticeable across a paragraph, which is why a page of passive constructions can feel flat even when every sentence is grammatical. The same effect shows up in the other patterns covered in what makes a sentence sound awkward.

Active voice also lets the verb do more of the work. "The committee decided" carries one idea in two words, while "a decision was reached by the committee" spreads it across five. When a sentence feels bloated, the fix is often not deleting words but finding the buried verb, the same instinct behind rephrasing a sentence for clarity.

When passive voice is actually the right choice

Passive isn't always wrong to use. It works when the action matters more than who did it, like "The bridge was completed in 1998," where naming a specific construction crew would be unnecessary detail. It's also standard in a lot of scientific writing, where the process matters more than the person running it.

The other honest reason to keep it is that you do not know the actor. "The server was misconfigured" may be the most accurate sentence available if nobody has established who changed the setting. Inventing an agent to satisfy a style rule produces a sentence that is active and false, which is a worse trade.

So the useful test is not "is this passive" but "does the reader need to know who acted, and does the sentence tell them." If the actor is genuinely unknown or irrelevant, the passive version is doing its job.

A few more pairs to practice on

• "The cake was eaten by the kids" becomes "The kids ate the cake."
• "A decision has been reached by the board" becomes "The board reached a decision."
• "Your request is being reviewed by our team" becomes "Our team is reviewing your request."
• "The invoice was paid by the client" becomes "The client paid the invoice."
• "The draft will be reviewed by the editor" becomes "The editor will review the draft."

In each pair the active version is shorter and puts the actor first, which is why it reads as more direct. If you find yourself converting a passive sentence and the active version sounds wrong, check whether you actually know who is doing the action.

When the actor is missing, decide who it is

A passive sentence often drops the actor entirely: "The package was shipped" or "The deadline was missed." To rewrite it actively you have to decide who did it, which is sometimes the real reason the writer chose passive voice in the first place. If the actor genuinely doesn't matter or is unknown, leave the sentence passive, it's the honest version. If you know who it was, naming them makes the sentence clearer and more accountable, and that is usually worth doing in business writing.

This is where passive voice stops being a style question. "It was decided that the launch would move" is grammatically fine and nearly useless, because it hides the one piece of information a reader wants. "The marketing team decided to move the launch" tells them who to ask, thank, or push back on. The same is true in status updates, where accountability usually matters more than the rhythm of the sentence.

Rephrasing a passive sentence

To convert passive to active, find who or what is doing the action (even if the sentence doesn't currently say so), and make that the subject.

On a longer sentence, work one clause at a time. Take "The revised budget was approved by the board after the projections had been checked by the analysts." There are two passive clauses, so unpack them both: the board approved the revised budget, and the analysts had checked the projections. Then decide how the two fit together. "The board approved the revised budget after the analysts checked the projections" keeps the meaning, drops the padding, and makes both actors visible.

Two mistakes are common here. The first is flipping the roles and moving the receiver to the front, which produces nonsense like "The budget approved the board." Read the result back and check that the actor is still the one acting. The second is converting a sentence whose actor was deliberately left out, which changes the meaning instead of tightening it.

If a sentence is still heavy after the conversion, the problem may be word choice rather than voice, which is the difference between swapping a synonym and rebuilding the sentence covered in synonym versus rephrase. And if the rewrite leaves two clauses jammed together with no punctuation, the repairs are in fixing a run-on sentence.
