Remendei a câmara de ar.

Remendei is the 1st person singular form of the verb remendar in the pretérito perfeito (simple past).

So remendei means I patched, I mended, or I repaired with a patch.

It is more specific than a general I fixed. It suggests repairing something by putting on a patch, which fits very well with a câmara de ar.

Remendei is the normal tense for a completed action in the past:

• Remendei a câmara de ar. = I patched the inner tube.

By contrast:

• remendava = I was patching / I used to patch
• tenho remendado in European Portuguese usually suggests a repeated or ongoing situation over a period of time, not just one finished action

So if you simply want to say that you did it and it is finished, remendei is the natural choice.

That a is the definite article, meaning the.

So:

• a câmara de ar = the inner tube
• uma câmara de ar = an inner tube

Portuguese uses definite articles more often than English does, so seeing a here is very normal.

Literally, câmara de ar means something like air chamber.

In everyday usage, it means inner tube, such as the inflatable tube inside a bicycle or car tyre.

So even though the literal words may look transparent, you should learn câmara de ar as a fixed expression meaning inner tube.

In Portuguese, de often links nouns in a way that English expresses with another noun or an adjective.

So:

• câmara de ar literally = chamber of air
• natural English = inner tube

This is very common in Portuguese. A word-for-word translation often sounds unnatural in English, even though the Portuguese is perfectly normal.

Not in this sentence.

In Portuguese, câmara can mean chamber, and in some contexts it can also appear in institutional names, like câmara municipal.

The usual word for a photographic camera in Portuguese is câmara in European Portuguese, but in câmara de ar, it definitely means chamber, not a photographic device.

So you should understand it from context.

A learner-friendly approximation is:

• câmara ≈ KAH-muh-ruh
• de ar ≈ duh AR or very reduced in connected speech

A few useful notes for European Portuguese:

• Unstressed vowels are often reduced.
• The first syllable of câmara is stressed: CÂ
• The de is often pronounced with a reduced vowel.
• In fast speech, the whole phrase can sound much more compressed than the spelling suggests.

If you want a rough overall approximation: Remendei a câmara de ar ≈ ruh-men-DAY-ee uh KAH-mruh d'AR

Yes, but the meaning changes slightly.

• remendar = to patch, mend with a patch
• consertar = to fix, repair
• reparar = to repair, though in European Portuguese it can sound a bit more formal or technical depending on context

Since an inner tube is very often repaired by applying a patch, remendar is especially appropriate and idiomatic here.

This is the normal Portuguese order:

Verb + object

• Remendei = I patched
• a câmara de ar = the inner tube

Portuguese often drops the subject pronoun when it is clear from the verb ending. Since remendei already tells us the subject is I, there is no need to say eu unless you want emphasis.

Yes, absolutely.

• Remendei a câmara de ar. = neutral, natural
• Eu remendei a câmara de ar. = I patched the inner tube, with extra emphasis on I

European Portuguese often omits subject pronouns unless they are needed for contrast, emphasis, or clarity.

Yes. Remendar is a regular -ar verb.

Its pretérito perfeito forms are:

• eu remendei = I patched
• tu remendaste = you patched
• ele/ela/você remendou = he/she/you patched
• nós remendámos = we patched
• vós remendastes = you all patched
• eles/elas/vocês remendaram = they/you all patched

So remendei follows the normal pattern for regular -ar verbs.

This is a spelling rule used to preserve pronunciation.

The verb stem ends in d, and the ending is -ei. So the form becomes remendei.

More importantly, Portuguese often changes spelling in some verb forms to keep the sound consistent, especially with letters like c, g, and ç. In this case, remendei is simply the correct regular form of remendar.

So it is best learned as:

• infinitive: remendar
• eu in the simple past: remendei

Yes. You can replace it with the direct object pronoun a:

• Remendei-a. = I patched it.

In European Portuguese, this spelling uses a hyphen because the pronoun is attached to the verb.

This is correct, but in everyday speech learners will very often hear and use the full noun phrase instead, especially at first.

Very often, yes.

When people say câmara de ar, a bicycle inner tube is a very common interpretation. But it can also refer to inner tubes in other contexts, depending on the situation.

So the sentence could naturally mean something like:

• I patched the bike inner tube.

If the context is cycling, that is probably what people will assume.

Yes, it is completely natural.

It is short, idiomatic, and grammatically normal. A European Portuguese speaker would easily understand it as a straightforward statement that the speaker patched an inner tube.
