In the active voice, the subject performs the action: The chef cooked the meal. In the passive voice, the subject receives the action, and the verb turns into a form of be (am, is, are, was, were, been, being) plus a past participle: The meal was cooked by the chef. Neither is more "correct" — the active voice is usually clearer and more direct, while the passive is the better choice when the doer is unknown, unimportant, or deliberately left out.
Every passive verb follows the same formula: a form of be + a past participle. If you can find that pattern and the subject is having something done to it, the sentence is passive.
The past participle is the "third form" of a verb — eaten, driven, chosen, sent, built, seen. When one of these sits after be and the subject is on the receiving end, you have the passive.
Warning: not every be verb is passive. This is the single most common mistake. A sentence needs a past participle doing the work of the verb — not just any is or was.
The same idea can almost always be phrased either way. The passive keeps the verb but shifts the spotlight from the doer to the receiver:
Notice the pattern: the object of the active sentence (the budget) becomes the subject of the passive one, and the original subject (the committee) moves into a by phrase — or disappears entirely.
The passive is a legitimate, useful tool — not an error. Reach for it when:
There is also the evasive passive — Mistakes were made — which quietly hides who is responsible. It is grammatically fine, but readers notice the dodge, so use it knowingly rather than by accident.
For most everyday writing, the active voice is the default because it is shorter, clearer, and assigns responsibility:
If a passage feels sluggish or bureaucratic, a pile-up of passives is often the reason.
Three steps turn a passive sentence active:
Worked example: The window was broken by the boy. → doer = the boy → the boy becomes the subject → was broken becomes broke → The boy broke the window.
Add "by zombies" after the verb. If the sentence still makes sense, it's passive:
It works because the passive always leaves room for a by-agent, whether or not one is actually stated.
Honestly, no. The way English forms and uses the active and passive voice is identical in American and British English — this is one grammar topic with no transatlantic split. The only nearby difference is agreement with collective nouns: British writers may treat a group as plural (The team were beaten), while American writers usually keep it singular (The team was beaten). That changes the be verb, not the voice itself.
Look for a form of 'be' (is, was, were, been, being) followed by a past participle, where the subject receives the action instead of doing it. A quick test: if you can add 'by zombies' after the verb and it still makes sense — 'The letter was signed by zombies' — the sentence is passive.
No. The passive voice is completely grammatical and often the best choice — when the doer is unknown, obvious, or unimportant, or when the receiver of the action is your real topic. The advice to 'avoid the passive' is about style, not grammar: active sentences are usually clearer and shorter, so they make a sensible default rather than a hard rule.
They are unrelated. Tense tells you when something happened; voice tells you whether the subject acts or is acted upon. You can be passive in any tense: 'is eaten' (present), 'was eaten' (past), 'will be eaten' (future). And plenty of past-tense sentences are active, such as 'The dog ate the bone.'
Because overusing it makes writing wordy, vague, and evasive — 'Mistakes were made' hides who is responsible. Active sentences are shorter and assign accountability, so they suit most writing. But blanket 'avoid passive' advice goes too far: checkers wrongly flag it, and skilled writers use the passive deliberately when it genuinely serves the sentence.
Yes, and it is often expected. Passive constructions like 'The solution was titrated' keep the focus on the method and results rather than the researcher, which suits an objective tone. That said, many modern journals now encourage active voice ('We titrated the solution') for clarity, so check your field's or publisher's style guide.
