Nie denerwuj się, przecież jeszcze mamy pięć minut do końca przerwy.

Because denerwuj is the imperative form: it means don’t get upset / don’t worry / don’t be nervous as a command or request.

• denerwujesz się = you are getting upset / you get upset
• denerwuj się = get upset!
• nie denerwuj się = don’t get upset!

So the speaker is telling someone not to do something, which is why Polish uses the imperative.

Się makes the verb reflexive here. The basic verb denerwować can mean to annoy / to upset someone:

• To mnie denerwuje = That annoys me

But denerwować się means to get upset / to become nervous / to worry:

• Denerwuję się = I’m getting upset / I’m nervous / I’m worried

So Nie denerwuj się is not literally don’t annoy, but don’t upset yourself / don’t get upset.

In Polish, a lot of emotional-state verbs use się in this way.

It can overlap with all of those depending on context, but here it most naturally means something like:

• Don’t worry
• Don’t get upset
• Don’t be so stressed

The verb denerwować się often suggests emotional agitation, stress, irritation, or nervousness. In this sentence, because the speaker adds we still have five minutes left, the idea is probably don’t worry / don’t panic.

Przecież is a very common Polish particle that adds the sense of:

• after all
• come on
• but
• you know
• obviously / as you know

In this sentence, it softens and supports the speaker’s point:

• Nie denerwuj się, przecież jeszcze mamy pięć minut...
• Don’t worry, we still have five minutes, after all.

It often reminds the listener of something that should already be clear or remembered.

Here jeszcze means still:

• jeszcze mamy pięć minut = we still have five minutes

Depending on context, jeszcze can also mean yet, more, or another, but here it clearly means that time remains.

Compare:

• Jeszcze czekam = I’m still waiting
• Jeszcze nie wiem = I don’t know yet
• Jeszcze kawy? = More coffee?

Because Polish commonly expresses remaining time with mieć (to have), just like English often does:

• Mamy pięć minut = We have five minutes
• In context: We still have five minutes left

It sounds very natural in Polish. You do not need a separate word for left here, because the phrase do końca przerwy already shows that these five minutes remain until the break ends.

Because after 5 and above, Polish nouns usually go into the genitive plural.

• jedna minuta = one minute
• dwie / trzy / cztery minuty = two / three / four minutes
• pięć minut = five minutes

So:

• 1 → nominative singular
• 2–4 → nominative plural-like form
• 5+ → genitive plural

That is why the sentence uses pięć minut.

Because do takes the genitive case and means to / until / up to in expressions of limit or endpoint.

The phrase means:

• do końca = until the end
• przerwy = of the break

So:

• do końca przerwy = until the end of the break

Case changes:

• koniec → końca (genitive singular)
• przerwa → przerwy (genitive singular)

This is a very common pattern:

• do domu = to home
• do rana = until morning
• do końca dnia = until the end of the day

Yes, that is close to the literal structure, but it sounds less natural in English.

A more natural English version would be something like:

• Don’t worry, we still have five minutes left before the break ends.
• Don’t get upset, we still have five minutes left of the break.

So the Polish structure is straightforward, but good English translation usually smooths it out a bit.

No, Polish word order is fairly flexible, although some versions sound more natural than others.

The original:

• Nie denerwuj się, przecież jeszcze mamy pięć minut do końca przerwy.

Possible alternatives:

• Nie denerwuj się, jeszcze mamy przecież pięć minut do końca przerwy.
• Przecież jeszcze mamy pięć minut do końca przerwy, nie denerwuj się.

The original sounds very natural because:

• first comes the calming command
• then comes the explanation
• przecież appears early, which gives the sentence that reassuring come on / after all tone

So the word order is not completely fixed, but the chosen order is idiomatic and expressive.

Because the sentence has two parts:

1. Nie denerwuj się
2. przecież jeszcze mamy pięć minut do końca przerwy

The first part is an imperative clause, and the second gives the reason or explanation. In Polish, a comma is normally used to separate such clauses.

So the punctuation matches the natural pause in speech:

• Don’t worry, after all we still have five minutes left.

Yes. Depending on the exact feeling, Polish might also use:

• Nie martw się = Don’t worry
• Nie stresuj się = Don’t stress out
• Nie przejmuj się = Don’t let it bother you / don’t worry about it

Compared with these:

• denerwować się suggests agitation, nerves, irritation, or emotional tension
• martwić się focuses more on worry
• stresować się focuses more on stress
• przejmować się focuses on taking something too much to heart

In this sentence, Nie denerwuj się sounds very natural and conversational.
