Active vs Passive — Why & When

You've probably been told this at some point — usually with a red pen, or a sigh, or both:

"Don't use the passive voice."

Then you turn the page in a textbook and there's a sentence like The window was broken by the ball, and someone says, "That's the passive." So now you're stuck. Is it bad? Is it fancy? If it's so forbidden, why is it right there in your book — and why do grown-ups use it all the time?

Here's the thing. Active and passive are just two different ways of telling the same story. One puts the person doing the action in the spotlight. The other puts the action — or the thing it happens to — in the spotlight. Nobody's born knowing this, and the "rule" you half-remember is really only half a rule.

Once you can see that, choosing between them gets much easier — and a lot less scary.

Before you read on, here's where we're heading. By the end of this article, you'll be able to: - Explain, in plain words, what active and passive voice actually mean. - Spot when the passive is genuinely useful — and when it just makes things vague. - Decide which voice fits your sentence, your reader, and your exam. - Rewrite a passive sentence into an active one and say why you changed it.

Beginner (Foundation): What active and passive are (without the fuss)

Let's start with something you say all the time — probably a dozen times a day without thinking about it:

• Active: The dog chased the cat.

You can picture it, can't you? The dog is doing the action. The cat is getting chased. Nice and simple.

Now flip it round:

• Passive: The cat was chased by the dog.

Same situation — same dog, same cat, same chase — but the cat is now sitting in the main seat of the sentence. We've pushed the dog to the end. And here's the clever part: we can even leave the dog out altogether.

• The cat was chased.

We still know something happened to that cat. We just don't know who did it.

So here's the simple idea, and it's the whole foundation for everything else:

• Active voice — the doer (the person or thing doing the action) comes first and feels like the star.
• Passive voice — the receiver (the person or thing the action happens to) comes first and feels like the star.

Let's look at a few pairs so it settles in:

• Active: My brother ate the last biscuit. Passive: The last biscuit was eaten by my brother.
• Active: The teacher explained the homework. Passive: The homework was explained by the teacher.
• Active: A hacker stole my password. Passive: My password was stolen by a hacker.

And notice — again — that in each passive version we can quietly drop the "by…" part:

• The last biscuit was eaten.
• The homework was explained.
• My password was stolen.

That's one of the big reasons people reach for the passive: sometimes the doer isn't known, or just isn't important. Hold that thought — we'll come back to it properly in a minute.

There's one more feel-check worth doing before we move on. Say these two out loud:

• Active: I spilled juice on the carpet.
• Passive: Juice was spilled on the carpet.

Same mess — different personality. The first one owns up. The second one, let's be honest, tiptoes a bit around the culprit. That little shift in who feels responsible is something we'll use later on purpose.

Common Mistake: Lots of pupils think any long or important-sounding sentence "must be passive." It isn't. Passive is about who's doing what to whom — not about how long or how grand a sentence sounds.

Pro-Tip: To spot the passive fast, hunt for a form of "be" (is, was, were, been, being) followed by a past participle (done, made, eaten, broken, written). Then ask yourself: "Can I add by someone at the end and still have it make sense?" If yes — you've almost certainly got a passive.

Quick recap: - Active: the doer comes first — The dog chased the cat. - Passive: the receiver comes first — The cat was chased (by the dog). - Passive usually looks like "be + past participle" — was eaten, is made, were stolen. - You can often drop the "by…" part in a passive sentence. - Passive isn't "bad" — it just aims the spotlight somewhere else.

Intermediate (Development): When to choose active or passive

Right — you know what active and passive are. Now for the question that actually matters: when should you use each?

Let's be honest — for most of the writing you do at school, your safest default is active. It's clearer, and it's got more punch:

• I finished my homework late. (active) is nearly always better than My homework was finished late by me. (passive)

That second one sounds like a robot filling in a form. So active wins by default. But — and this is the bit people forget — the passive has some very useful jobs. Here are the big ones.

1. When you don't know who did it

Imagine you get to school and find this:

• The bike rack was damaged last night.

You don't know who damaged it. You only know the result. Passive is perfect here, because the doer is genuinely unknown.

If you forced it into the active, you'd end up guessing:

• Someone damaged the bike rack last night.

That's not wrong — but it drags in a vague "someone" you don't actually know anything about. The passive lets you point at the thing that happened without pretending you know more than you do.

2. When the doer isn't important

Sometimes we simply don't care who did it. We care about the action, or the result.

• Year 11 exams will be held in June. (No need for "The school will hold Year 11 exams in June" — nobody's wondering which member of staff.)
• Mobile phones are not allowed in the exam hall. (No need for "Teachers do not allow mobile phones…")

The passive makes these sound like general rules — not one particular person's decision on one particular day.

3. When you want to be polite or careful

Passive can soften your tone. It's handy when you're giving feedback, or pointing out a problem, and you don't want to sound like you're jabbing a finger at someone.

Compare:

• Active: You spelled [US: spelled/spelt] my name wrong.
• Passive: My name was spelled wrong.

The second one feels a bit gentler, doesn't it? A bit less "this is your fault."

Or:

• Active: You broke the model.
• Passive: The model was broken.

Sometimes that softer touch is exactly what you need — with a friend, a classmate, or even a teacher on a bad day.

4. When you want to focus on the result

In science and technical writing, the result is often more interesting than the scientist. You'll see lines like:

• The solution was heated to 80°C.
• The mixture was stirred for five minutes.
• The plant's growth was measured every day.

In a school lab report, that's completely normal — the focus is on what happened, not on "I did this, then I did that, then I did the other."

Common Mistake: Thinking "science = passive, always." Not quite. Your explanation or conclusion in a write-up is often clearer in the active: We found that the solution changed colour [US: color] beats It was found that the solution changed colour almost every time.

Let's gather a few pairs and actually choose — because that's the real skill here.

• Poster for the school play: A. Tickets are sold in the office. B. The office sells tickets. Both work — but A (passive) reads more like a sign: short, and focused on the tickets, which is what you care about.
• Story opening: A. The window was broken by a football. B. A football smashed the window. B (active) is far more vivid. In a story, you want the football doing the damage in front of the reader.
• School rule: A. Chewing gum is banned in class. B. Teachers ban chewing gum in class. A (passive) sounds like a proper rule; B sounds like you're personally blaming the teachers — as if it's a grudge rather than a policy.

Pro-Tip: Quick rule of thumb: if your sentence is about rules, procedures, or general truths, the passive often fits nicely. If it's about a character doing something in a story, active nearly always wins.

Quick recap: - Use active as your default — it's clearer and stronger. - Use passive when the doer is unknown — My bag was stolen. - Use passive when the doer isn't important — Phones are not allowed. - Use passive to soften blame or criticism — The answer was copied. - In science, passive often highlights the process and the result.

Advanced (Mastery): Style, myth-busting, and the subtle choices

Now for the genuinely interesting bit — how writers play with active and passive to get exactly the effect they're after.

The myth: "Never use the passive"

You'll see people online shouting this as though it were a law carved into stone. It isn't. It's a piece of advice that got promoted to a fake rule somewhere along the way.

What teachers usually mean is something more like:

"Don't hide your meaning behind unnecessary passive sentences."

Compare:

• Active: The school changed the uniform rules without asking us.
• Passive: The uniform rules were changed without consultation.

The passive version sounds like it fell out of a very dull letter. It hides who did the changing. That might suit the school just fine — but it's less useful if you're a pupil trying to argue your case.

And sometimes you want to hide the doer. Politicians are famous for it:

• Mistakes were made.

Notice how neatly that dodges saying who made them. That's not "bad grammar" — it's a choice. It's just not always an honest one.

So instead of "never use the passive," try this:

• Use passive when it genuinely helps your reader — clearer, fairer, or more accurate.
• Avoid passive when it's dodging responsibility or turning your writing to fog.

Shifting blame — and sympathy

Look at these two:

• The glass was broken by Ben.
• Ben broke the glass.

The first one gives you a split second where you picture the broken glass before you even hear Ben's name. The second hits you with Ben first, then the crime.

If you're Ben, you might quietly prefer the passive. If you're Ben's mum, you're going straight for the active.

Writers use this trick constantly — especially in news reports:

• A protester was injured by police. versus
• Police injured a protester.

Same facts. Very different feeling. That's not an accident — that's someone choosing where to point the camera.

Keeping your writing alive

In exams, markers often grumble about "flat" or "lifeless" writing — and an overload of passive is one of the usual suspects.

Feel the difference:

• The ball was thrown, the goal was scored, and the match was won.
• Jamal hurled the ball, Toby slammed it into the net, and the crowd exploded.

Both describe a win. Only one sounds like something you'd actually want to read. I still use the passive myself, even in stories — but I try to choose it, not slide into it out of habit. That's the whole game, really.

Common Mistake: Trying to "sound formal" by turning every sentence passive, especially in an English essay. Examiners care far more about clarity and precision than about fake grandeur — a page of passive doesn't read as clever, it reads as tired.

Different tasks, different mixes

You'll meet active and passive across all sorts of school work, and each one leans a slightly different way:

• Narrative (stories): mostly active, with the odd passive dropped in for effect.
• Persuasive (letters, speeches, articles): mostly active to sound strong and clear — passive now and then to talk about rules, processes, or "what people say."
• Reports (science, geography, history): a mix — passive for experiments and processes, active for your explanations and arguments.

The good news is that the underlying mechanics — how you actually build passive verbs in different tenses — are the same everywhere. In this article we've stayed on the choice: the why and the when. If you want the step-by-step of forming the passive, that lives in its own article (C2 — How to Form the Passive), so this one doesn't turn into a conjugation drill.

Pro-Tip: When you edit a paragraph, try this quick pass. Highlight every passive verb. For each one, ask: "If I make this active, does it get clearer, sharper, or more honest?" Keep the passives that genuinely earn their place — change the rest. You'll be surprised how many just quietly disappear.

Quick recap: - "Never use the passive" is a myth — the real rule is "don't hide meaning behind it." - Passive can shift blame or soften it — Mistakes were made versus We made mistakes. - Too much passive makes writing dull; active usually feels more alive. - Different tasks (stories, reports, essays) call for different mixes. - The formation rules live in a separate article — here, it's all about why you choose.

A quick UK vs US note

For active and passive, the grammar is exactly the same in UK and US English — there's no hidden difference in how the voices work, so don't go looking for one. The only things that shift are spellings, like:

• colour [US: color]
• spelt [US: spelled]

I've used the UK spellings in the main text, with the US version in square brackets where it might trip you up.

Key Takeaways

• Active voice puts the doer first and is usually clearer and stronger.
• Passive voice puts the receiver first — useful when the doer is unknown, unimportant, or better left in the background.
• The passive isn't "wrong," but overusing it makes writing vague or dull.
• Stories and arguments usually want active; rules, processes, and some science writing often want passive.
• The smart move is to choose your voice on purpose — not obey a fake "never passive" rule.

Check Your Understanding

1. Label each sentence ACTIVE or PASSIVE.

a) The cake was eaten before lunch. b) Lena finished her project early. c) The posters were designed by the art club. d) Our team won the match.

2. Rewrite these passive sentences in active voice. Keep the meaning the same.

a) The window was left open all night. b) The prizes will be given out at the end of assembly. c) The test was marked by Mr Singh.

3. For each pair, choose the sentence that would work better in a story.

a) 1. The treasure was discovered by the explorers. 2. The explorers discovered the treasure.

b) 1. The alarm was set for midnight. 2. I set the alarm for midnight.

4. For each situation, say whether active or passive is probably better, and give a possible sentence.

a) A sign on the classroom door about phones. b) A diary entry about how you broke your phone.

5. Short explanation. Why might a politician say "Mistakes were made" instead of "We made mistakes"?
