Feche a porta com cuidado.

Feche is the imperative form used for você in Brazilian Portuguese.

The verb is fechar = to close.
For commands with você, Portuguese often uses the same form as the present subjunctive:

• que você feche = that you close
• feche! = close!

So Feche a porta means Close the door when speaking to você.

By contrast:

• fecha is usually the tu command in many varieties: Fecha a porta.
• In Brazil, many people use você much more often than tu, so feche is very common.

Usually, yes—or at least neutral/polite.

Because it uses the você command form, Feche a porta com cuidado sounds appropriate in many everyday situations. It is not extremely formal, but it is more polite or standard-sounding than some very casual alternatives.

Compare:

• Fecha a porta com cuidado. → more associated with tu or a more casual tone in some regions
• Feche a porta com cuidado, por favor. → more polite
• Fecha a porta aí. → much more casual

So feche is a safe form for learners to recognize and use.

Because a porta means the door.

Portuguese uses definite articles very often, just like English does here:

• a porta = the door
• uma porta = a door

In this sentence, the speaker means a specific door, so a porta is natural.

Also remember:

• a = singular feminine the
• porta is a feminine noun, so it takes a

You usually learn the noun together with its article:

• a porta

That tells you it is feminine.

Many Portuguese nouns ending in -a are feminine, and porta follows that common pattern. Because it is feminine, related words must match it:

• a porta
• a porta fechada = the closed door

Gender in Portuguese is grammatical, so it does not mean the object itself is biologically female.

Literally, com cuidado means with care.

In natural English, that usually becomes:

• carefully
• with care
• be careful when closing it

Portuguese often uses a preposition + noun expression where English prefers an adverb.

So:

• Feche a porta com cuidado. = Close the door carefully.

It can. Portuguese also has the adverb cuidadosamente, which means carefully.

So you could say:

• Feche a porta cuidadosamente.

But com cuidado is often more common and more natural in everyday speech. It sounds simple and idiomatic.

Compare:

• com cuidado → very common in daily conversation
• cuidadosamente → correct, but sometimes a bit more formal or written

Yes. Word order is somewhat flexible.

These are all possible:

• Feche a porta com cuidado.
• Com cuidado, feche a porta.
• Feche com cuidado a porta. (possible, but less natural in everyday speech)

The most natural everyday order is usually:

• verb + object + com cuidado

So Feche a porta com cuidado is the most straightforward version.

It is understood and usually omitted.

Portuguese often drops subject pronouns when the verb form already makes the meaning clear enough. In commands, this is especially common.

So:

• Feche a porta. = (You) close the door.

If you add the pronoun, it is usually for emphasis or clarity:

• Você, feche a porta. = You, close the door.

But in normal speech, just Feche a porta is enough.

In a tu variety, the command is usually:

• Fecha a porta com cuidado.

So the difference is:

• você command: Feche a porta com cuidado.
• tu command: Fecha a porta com cuidado.

Be aware that Brazil has regional differences:

• In many places, people mostly use você
• In some regions, tu is common
• Real-life usage can mix forms depending on region and speaker

The negative command is:

• Não feche a porta com cuidado.

Grammatically, that means Don’t close the door carefully, which sounds a bit odd in English because it suggests the person may close it, just not carefully.

If what you really mean is something like Don’t close the door or Be careful not to slam the door, Portuguese would usually say something more natural, such as:

• Não feche a porta. = Don’t close the door.
• Tome cuidado ao fechar a porta. = Be careful when closing the door.
• Não bata a porta. = Don’t slam the door.

So the direct negative is possible, but context matters.

A common Brazilian pronunciation is approximately:

• FEH-shee

More carefully:

• fe- sounds like fe in get, but a bit tenser
• -che often sounds like shee in many Brazilian accents

So feche is often close to FEH-shee.

And the full sentence is roughly:

• FEH-shee a POR-tah kõ kwee-DAH-doo

A few notes:

• porta often has an open o sound: POR-ta
• com has a nasal vowel, so it is not exactly like English comb
• pronunciation varies across Brazil

Not if you want a direct command.

• Feche a porta com cuidado. = Close the door carefully. (command)
• Fechar a porta com cuidado = To close the door carefully (infinitive phrase)

The infinitive fechar does not work by itself as a normal command in Portuguese.

Here are a few:

• Feche a porta devagar. = Close the door slowly.
• Feche a porta com cuidado, por favor. = Close the door carefully, please.
• Fecha a porta com cuidado. = Close the door carefully. (tu / more casual in some regions)
• Tome cuidado com a porta. = Be careful with the door.
• Não bata a porta. = Don’t slam the door.

Each one has a slightly different nuance:

• com cuidado = carefully / with care
• devagar = slowly
• não bata a porta = specifically warns against slamming it

Yes, definitely.

It sounds natural and clear in Brazilian Portuguese. A native speaker might also choose slightly different wording depending on tone and situation, but Feche a porta com cuidado is completely normal and understandable.

In everyday life, you may also hear:

• Fecha a porta com cuidado
• Fecha a porta devagar
• Feche a porta, por favor

So the sentence is both grammatical and practical for real use.
