When be meant to is close to be supposed to
Be meant to can express what is intended, expected, or envisaged in a plan. Meant is the past participle of mean in the sense of intending something; together with be, it forms a structurally passive construction.
In statements about plans or purposes, be meant to and be supposed to are often similar. Their meanings do not overlap completely, however: is supposed to be excellent can report other people's opinion of the quality, while is meant to be excellent can describe an intention or expected standard.
The key is not to confuse this construction with a simple I meant to call you, meaning “I intended to call you”. There, meant is the past tense of mean in the sense of intending, without be in the same role. In be meant to, meant belongs to the complete predicate is/are/was/were meant to; it is not an independent Past Simple verb.
This backup battery is meant to keep the alarm running during a power cut.
This backup battery is meant to keep the alarm running during a power cut.
This describes a device's purpose: is meant to is equivalent to is supposed to here, but sounds slightly more natural for an inbuilt function.
I meant to reply to your message yesterday, but the day got away from me.
I meant to reply to your message yesterday, but the day got away from me.
This is a different construction: meant is an independent Past Simple verb meaning “intended”, without be or a passive meaning. Do not confuse it with be meant to.
Form: be + meant to + base form
This pattern requires be, agreeing with the subject and tense: I am, he/she/it is, you/we/they are; in the past, was/were. Meant does not change.
Use the base form after meant to: meant to arrive, not meant to arriving. The whole phrase to arrive is a to-infinitive.
Form negatives through a negative form of be — isn't/aren't/wasn't/weren't meant to — not through doesn't/don't/didn't. Meant is a participle in the complete predicate, not a main verb that takes do-support.
Form questions by inverting be and the subject: Is this meant to...? or Were they meant to...? This follows the usual question pattern with be.
Subject + am/is/are/was/were (+ not) + meant to + base form
- subject / S —
- The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
- V1 / base form —
- The base verb without to: work, go, be.
Is this software patch meant to fix the login problem?
Is this software patch meant to fix the login problem?
The question inverts is and the subject this software patch: be carries the question structure.
The delivery drones weren't meant to fly after sunset.
The delivery drones weren't meant to fly after sunset.
The negative uses weren't, not didn't: meant is not an independent main verb here.
The night bus is meant to run every fifteen minutes.
The night bus is meant to run every fifteen minutes.
Use the base form run after to, without -ing and without omitting to.
Purpose and design
The most natural domain of be meant to is the intended function of an object, system, or mechanism: what it was designed or programmed to do, whether or not it actually works that way.
The subject is often inanimate — a device, system, or space — and the source of the intention is a developer, manufacturer, or designer who is not explicitly named in the sentence.
This greenhouse vent is meant to open automatically once the temperature climbs too high.
This greenhouse vent is meant to open automatically once the temperature climbs too high.
This describes the mechanism's intended function, not an arrangement with someone.
The membership card is meant to work at every branch, not just this one.
The membership card is meant to work at every branch, not just this one.
Again, this describes an object's purpose: a feature intended when the card was issued.
Arrangement and expectation
The same construction describes an agreed plan or expected behaviour by people, the same role that be supposed to plays in the related rule about expected behaviour. Here, the subject is often a person or group of people rather than a device.
In this meaning, be meant to answers “What has been agreed or planned?”, rather than “What was this created for?”
The tour guide is meant to meet the group by the fountain at nine.
The tour guide is meant to meet the group by the fountain at nine.
This is an agreed plan involving people, not a property of an object.
We're meant to hear back about the venue by Friday.
We're meant to hear back about the venue by Friday.
This is an event expected under an arrangement or schedule, without a guarantee that it will happen.
A past intention and the actual outcome
Was/were meant to names a past intention. It is often used to explain what did not go according to plan, but non-fulfilment is not obligatory: The meeting was meant to start at nine, and it did.
A natural companion to such a sentence is a contrast: but, however, yet, or simply a following sentence stating what actually happened.
The graduation ceremony was meant to finish by noon, but the speeches ran long.
The graduation ceremony was meant to finish by noon, but the speeches ran long.
A past plan and what actually happened form a typical pairing with was meant to.
The garden hose reel was meant to arrive last week.
The garden hose reel was meant to arrive last week.
This names an expected deadline in the past. The sentence itself neither confirms nor denies delivery.
Register and limits of meaning
Both constructions can describe a plan, rule, or purpose. Paraphrasing is often appropriate in that context; outside it, check the meaning rather than replacing words automatically.
Affirmative be supposed to for expected behaviour or rules belongs to the related rule “Expected behaviour or rules”; negative not supposed to and its contrast with past wasn't supposed to belong to another related rule. Here we do not repeat that material, but practise the form and use of be meant to specifically.
Should have can evaluate a past action, while was meant to names an intention or arrangement. However, be meant to can also sound reproachful: You were meant to call me. The speaker's intention depends on context and intonation.
The warranty seal is meant to stay unbroken until a technician opens the device.
The warranty seal is meant to stay unbroken until a technician opens the device.
An object's purpose is expressed through be meant to, a natural choice for describing the function of a sticker or seal.
The orchestra rehearsal is meant to start at seven, the same as always.
The orchestra rehearsal is meant to start at seven, the same as always.
This is an agreed, usual schedule: another arrangement meaning where be supposed to would fit equally well.
Common mistakes
Incorrect:This paper shredder is meant destroy documents in seconds.
Correct:This paper shredder is meant to destroy documents in seconds.
In be meant to, meant requires to before the base verb; it is part of this construction, not merely a descriptive adjective.
Incorrect:This paper shredder is meant to destroying documents in seconds.
Correct:This paper shredder is meant to destroy documents in seconds.
After to in this construction, always use the base verb, not -ing, even when the subject is a mechanism.
Incorrect:The sprinklers is meant to activate automatically during a fire.
Correct:The sprinklers are meant to activate automatically during a fire.
Plural sprinklers requires are, not is, regardless of the fact that the verb after to is the same for both numbers.
Incorrect:The intercom were meant to reach every floor of the building.
Correct:The intercom was meant to reach every floor of the building.
Intercom is singular, so its past-tense form requires was, not were.
Incorrect:This revolving door doesn't meant to stay open during business hours.
Correct:This revolving door isn't meant to stay open during business hours.
Meant is a participle after be, not a base-form main verb; form the negative with isn't/aren't, not doesn't.
Incorrect:The loyalty card scanner meant to read cards instantly, but it kept freezing.
Correct:The loyalty card scanner was meant to read cards instantly, but it kept freezing.
To say that the scanner was designed to read cards, use was meant to. Meant to without be exists as an active intention construction — I meant to call — but does not convey the required purpose meaning here.
