Questions & Answers about Se o colchão não couber no elevador, vamos subir com ele pelas escadas.
Why is it se o colchão não couber and not se o colchão não cabe?
Because Portuguese usually uses the future subjunctive after se when talking about a possible future situation.
- Se o colchão não couber... = If the mattress doesn’t fit...
- This refers to something that may happen later.
The form couber is the future subjunctive of caber.
By contrast, se o colchão não cabe sounds wrong in standard Portuguese for this kind of future condition. The present tense cabe is not normally used here.
A similar pattern:
- Se chover, ficamos em casa. = If it rains, we’ll stay home.
- Se der tempo, eu vou. = If there’s time, I’ll go.
So this is a very important pattern in Portuguese:
- se + future subjunctive
- then a main clause, often with future meaning
What verb is couber from?
It comes from the verb caber, which means to fit or to have enough room.
In this sentence:
- o colchão caber no elevador = the mattress fit in the elevator
Caber is irregular, so its forms do not always look predictable.
Some useful forms:
- cabe = it fits
- cabia = it used to fit / it would fit
- coube = it fit / it managed to fit
- couber = if it fits / when it fits (future subjunctive)
So couber may look strange at first, but it is just an irregular form of caber.
How do I know couber is future subjunctive?
A very practical trick is this: many future subjunctive forms in Portuguese are based on the third person plural of the preterite.
For caber:
- preterite: coube = it fit
- third person plural: couberam = they fit
- remove -am → couber
That gives you the future subjunctive stem/form:
This pattern works for many verbs:
- fizeram → fizer
- tiveram → tiver
- vieram → vier
So couber is the future subjunctive form used after se.
Why is it no elevador?
Why does the sentence use vamos subir instead of a simple future like subiremos?
Both are possible, but vamos subir is much more common in everyday Brazilian Portuguese.
- vamos subir = we’re going to take / bring it up
- subiremos = we will take / bring it up
In Brazil, the ir + infinitive structure often sounds more natural and conversational than the simple future.
So:
- vamos subir com ele pelas escadas sounds normal and everyday
- subiremos com ele pelas escadas sounds more formal or written
This is similar to English preferring we’re going to... in many situations.
What does subir com ele mean exactly? Why com ele?
Literally, subir com ele means go up with it.
Here, ele refers to o colchão, which is masculine. So:
- o colchão → ele
In natural English, we would usually say:
- we’ll carry it up the stairs or
- we’ll take it up the stairs
Portuguese often expresses this with subir com [something] in contexts like moving an object upward together with you.
So com ele is not weird in Portuguese. It means the mattress is coming up with the people.
Why is it ele and not isso or o?
Because ele is a normal pronoun used to refer back to a masculine noun.
- colchão is masculine
- so it can be referred to as ele
Portuguese often uses ele/ela for objects, not just people.
So this is perfectly normal:
Could Portuguese also use another structure? Yes. For example:
- vamos subi-lo pelas escadas
But in Brazilian Portuguese, that sounds more formal or less common in speech. Subir com ele is much more natural in everyday conversation.
Why is it pelas escadas and not por as escadas?
Because pelas is the contraction of:
- por + as = pelas
So:
- pelas escadas = through / by way of / via the stairs
Just like:
- pelo corredor = through the hallway
- pela porta = through the door
These contractions are standard and required in normal Portuguese.
Why is it escadas in the plural?
Portuguese often uses escadas in the plural where English says the stairs.
So:
- pela escada = by the staircase / by the stairway
- pelas escadas = by the stairs / up the stairs
In many real-life contexts, escadas is the most natural choice when talking about using the stairs in a building.
This is similar to English, which also usually says the stairs, not the stair.
Why is there o before colchão and elevador, and as before escadas?
Portuguese uses definite articles very often, sometimes more often than English does.
Here:
- o colchão = the mattress
- o elevador = the elevator
- as escadas = the stairs
Even when English might sometimes omit an article in a more general statement, Portuguese often keeps it.
Also, the articles show gender and number:
- o = masculine singular
- a = feminine singular
- os = masculine plural
- as = feminine plural
- colchão is masculine singular
- elevador is masculine singular
- escadas is feminine plural
the articles match accordingly.
Could I say Se o colchão não entrar no elevador instead?
Yes, and that would also sound natural, but it is slightly different in focus.
- caber focuses on fitting
- entrar focuses on going into / entering
So:
- Se o colchão não couber no elevador = If the mattress doesn’t fit in the elevator
- Se o colchão não entrar no elevador = If the mattress won’t go into the elevator
In many situations, both work.
But caber is especially precise when the issue is size or space.
What is the function of pelas escadas in the sentence?
Is the word order fixed here, or could it be changed?
The given order is very natural:
But Portuguese allows some flexibility. For example:
- Se o colchão não couber no elevador, vamos subir pelas escadas com ele.
This is understandable, but it may sound slightly less smooth depending on context.
The original version sounds natural because it keeps:
- the condition first
- then the action
- then the route
So for a learner, the original sentence is a very good model to copy.
How is colchão pronounced, especially the ão ending?
The ending -ão is a nasal sound, which can be difficult for English speakers.
colchão is roughly pronounced like:
- kol-SHAWN, but with a nasal ending, not a full English n sound
A few tips:
- lh in colchão sounds like the lli in million for many English speakers
- stress falls on the last syllable: col-CHÃO
- ão is nasal, so air passes through the nose slightly
You do not pronounce it like:
- col-chao with a clear ow
- or col-chan
The nasal ending is one of the most important pronunciation features in Portuguese.
Is this sentence typical of spoken Brazilian Portuguese?
Yes, very much so.
It sounds natural and everyday because it uses several common spoken patterns:
- se + future subjunctive → se ... couber
- vamos + infinitive → vamos subir
- a natural pronoun choice → com ele
- common contractions → no, pelas
So even though it contains some grammar that is tricky for learners, it is absolutely normal Brazilian Portuguese.
