Precisamos sair depressa.

Portuguese often drops subject pronouns when the verb form already makes the subject clear.

Precisamos is the we form of precisar, so nós is understood automatically.

• (Nós) precisamos sair depressa. = We need to leave quickly.

Adding nós is possible, but it usually sounds more explicit or emphatic:

• Nós precisamos sair depressa.

In everyday Brazilian Portuguese, leaving out nós is very common.

Precisamos comes from the verb precisar, which usually means to need.

Here, precisamos is the 1st person plural form in the present indicative:

• eu preciso = I need
• você/ele/ela precisa = you/he/she needs
• nós precisamos = we need
• vocês/eles/elas precisam = you/they need

So precisamos means we need.

After precisar, Portuguese commonly uses another verb in the infinitive to say what needs to be done.

So the structure is:

• precisar + infinitive

Examples:

• Preciso estudar. = I need to study.
• Precisamos sair. = We need to leave.
• Eles precisam trabalhar. = They need to work.

That is why you get precisamos sair, not a conjugated form like precisamos saímos.

In many situations, it can be understood as either need to or have to, depending on context.

• Precisamos sair depressa. can feel like:
  • We need to leave quickly
  • We have to leave quickly

In Portuguese, precisar + infinitive often covers both ideas.

If you want another very common way to say have to, Brazilian Portuguese also uses:

• Temos que sair depressa.

That sounds very natural too.

Sair basically means to go out, to leave, or to get out, depending on context.

In this sentence, the most natural translation is usually to leave.

Examples of sair in different contexts:

• Vou sair de casa. = I’m going to leave the house.
• Vamos sair hoje à noite. = We’re going out tonight.
• Sai daqui! = Get out of here!

So sair is a flexible verb, and context tells you whether it means leave, go out, or get out.

Depressa means quickly, fast, or in a hurry.

In this sentence, depressa works like an adverb describing how you need to leave.

• Precisamos sair depressa. = We need to leave quickly.

It is very similar to rapidamente, but depressa often sounds a bit more everyday and conversational.

Compare:

• Fala depressa. = Speak quickly.
• Fala rapidamente. = Speak quickly.

Both are correct, but depressa is often more common in speech.

Because here you need an adverb, not an adjective.

• rápido / rápida = fast, quick as an adjective
• depressa = quickly as an adverb

In Precisamos sair depressa, depressa modifies the verb sair, so it tells you how you are leaving.

Compare:

• um carro rápido = a fast car
• sair depressa = to leave quickly

In informal Brazilian Portuguese, you may hear rápido used adverbially in speech, but depressa is the safer standard choice here.

The most natural word order is:

• Precisamos sair depressa.

Putting depressa after sair sounds normal and natural.

Precisamos depressa sair is not the usual word order in modern Brazilian Portuguese and sounds awkward.

You could sometimes move the adverb for emphasis in other sentence types, but for a learner, the best pattern is:

• precisar + infinitive + adverb

So:

• Precisamos sair depressa.

In Brazilian Portuguese, sair is usually pronounced roughly like sah-EER, with the stress on the last syllable.

A helpful approximation:

• sa = like sa in father
• ir = like eer

So:

• sair ≈ sah-EER

The a and i are pronounced separately, so it is not one single English-style vowel sound.

A rough English-style approximation is:

• preh-see-ZAH-moos sah-EER jeh-PRESS-ah

A few notes:

• Precisamos has stress on -sa-: pre-ci-SA-mos
• sair has stress on the last syllable: sa-IR
• depressa has stress on pres: de-PRES-sa

In Brazilian Portuguese, the final s in precisamos is often pronounced like a clear s sound, and de in depressa may sound more like ji or dji depending on accent.

Yes, absolutely.

• Precisamos sair depressa.
• Nós precisamos sair depressa.

Both are correct.

The version without nós is more common because the verb already shows the subject. The version with nós can sound more emphatic, clearer, or contrastive.

For example:

• Eles podem ficar, mas nós precisamos sair depressa.
  = They can stay, but we need to leave quickly.

Yes, depressa is common and perfectly natural in Brazilian Portuguese.

You may also hear:

• rápido
• rapidamente
• com pressa = in a hurry

Related expressions:

• Estou com pressa. = I’m in a hurry.
• Anda depressa! = Walk quickly! / Hurry up!
• Precisamos sair com pressa. = We need to leave in a hurry.

So depressa is a very useful everyday word to know.
