Hoje não dá para descansar, porque ainda preciso de terminar o relatório.

It is built from the verb dar (to give), but here it is part of the idiomatic expression dar para + infinitive.

In this sentence, não dá para descansar means something like:

• it’s not possible to rest
• there’s no way to rest
• I can’t really rest

So dar para does not mean give for here. It is an impersonal expression used to talk about possibility or practicality.

Both are possible, but they are not exactly the same.

• não posso descansar = I can’t rest
  This sounds more direct and personal.

• não dá para descansar = it’s not possible to rest / there’s no chance to rest
  This sounds a bit more general or situational, as if the circumstances do not allow it.

In your sentence, não dá para descansar suggests: today, because of the situation, resting is not really an option.

Because this expression normally uses para + infinitive:

• dá para fazer
• dá para sair
• dá para descansar

The para introduces the action that is possible or feasible. So dar para + infinitive is the standard pattern here.

In Portuguese, não normally goes directly before the verb it negates.

So:

• dá = it is possible / it works
• não dá = it is not possible / it doesn’t work

That is why you get:

• Hoje não dá para descansar

This is the normal position for negation in Portuguese.

Here ainda means still.

So:

• ainda preciso de terminar o relatório = I still need to finish the report

It shows that the action has not been completed yet. The report is not finished, and that unfinished task is the reason resting is not possible.

In European Portuguese, the verb precisar is very commonly used with de:

• precisar de fazer alguma coisa
• preciso de estudar
• preciso de terminar o relatório

So in Portugal, precisar de + infinitive is standard and very natural.

This is an important point because English speakers often expect need + infinitive with no extra word, but Portuguese works differently here.

In European Portuguese, preciso de terminar is the more standard and expected form.

You may hear preciso terminar especially in Brazilian Portuguese, where dropping de is much more common. But for Portugal Portuguese, it is best to learn and use:

• preciso de terminar
• precisas de sair
• precisamos de falar

So if your target is Portuguese from Portugal, keep the de.

Because here it means because and introduces the reason:

• Hoje não dá para descansar, porque ainda preciso de terminar o relatório.

In Portuguese:

• porque = because
• porquê = the reason / the why
• por que = used in some question structures
• por quê = usually at the end of a question

In this sentence, it is simply the conjunction because, so porque is correct.

The comma separates the main idea from the reason clause:

• Hoje não dá para descansar,
• porque ainda preciso de terminar o relatório.

This is very common when porque introduces an explanation. In short, the comma helps readability and clearly marks the second clause.

Portuguese often uses the definite article where English might not.

So:

• o relatório = the report

This usually refers to a specific report already known in the context: the report I’m working on, the report we mentioned, the report that has to be finished.

Using the article sounds natural here. Bare nouns are less common in this kind of sentence.

Hoje is not fixed at the beginning. Portuguese word order is flexible.

You could also say:

• Não dá para descansar hoje, porque ainda preciso de terminar o relatório.
• Porque ainda preciso de terminar o relatório, hoje não dá para descansar.

But the original sentence is very natural. Putting Hoje first gives it emphasis, like: As for today...

Descansar mainly means to rest.

It can overlap with to relax, but the core idea is rest, recovery, taking a break, physically or mentally.

For example:

• preciso de descansar = I need to rest
• vou descansar um bocado = I’m going to rest a bit

If you specifically mean relax in the sense of unwinding, Portuguese might also use relaxar, but descansar is very common and natural in everyday speech.

Yes, terminar and acabar can both mean to finish, and in many contexts either works.

So you could say:

• preciso de terminar o relatório
• preciso de acabar o relatório

Both are natural. Terminar is slightly more straightforward here, and many learners find it easier because it closely matches English terminate/finish, though the everyday meaning is simply finish.

In European Portuguese, não is pronounced roughly like nowng, but that is only an approximation.

A few useful points:

• it is one syllable
• the vowel is nasal
• the o is not pronounced like a clear English oh

English speakers often pronounce it too openly. Try to hear it as a short nasal sound rather than two separate sounds.

So in the sentence:

• Hoje não dá para descansar

make sure não stays compact and nasal.
