Termin na odstąpienie od umowy upłynie w piątek.

Here termin means deadline, time limit, or final date.

In everyday Polish, termin can also mean:

• an appointment
• a scheduled date
• a due date

But in this sentence, because it is followed by na odstąpienie od umowy, it clearly means the deadline for withdrawing from the contract.

Because termin na coś is a common Polish pattern meaning deadline/time limit for something.

So:

• termin na odstąpienie od umowy = the deadline for withdrawal from the contract

The preposition na often means for in this kind of context.

Compare:

• czas na odpoczynek = time to rest / time for rest
• miejsce na parking = space for parking
• termin na złożenie dokumentów = deadline for submitting documents

Odstąpienie od umowy is a formal legal expression meaning withdrawal from a contract or cancellation of a contract by exercising a legal right to back out.

Breakdown:

• odstąpienie = withdrawal, backing out
• od umowy = from the contract

This is more formal and legal than just saying you cancel something in everyday speech.

Umowy is in the genitive singular.

That is because the noun odstąpienie commonly takes od + genitive:

• odstąpienie od czego? = withdrawal from what?
• od umowy = from the contract

So:

• umowa = contract
• od umowy = from the contract

This is a very common Polish pattern:

• odchodzić od stołu = to move away from the table
• rezygnacja od... is not correct here, but odstąpienie od... is the fixed legal phrase

Upłynie is the 3rd person singular future form of the verb upłynąć.

It agrees with termin, which is singular:

• termin upłynie = the deadline will expire / will pass

The verb upłynąć is perfective, so its simple future form expresses a completed future event:

• upłynie = will expire / will elapse

Literally, upłynąć means something like to pass or to elapse, especially with time.

But with words like termin, natural English usually prefers:

• the deadline will expire
• the deadline will end
• the period will expire

So in this sentence:

• Termin ... upłynie w piątek = The deadline ... will expire on Friday

A more literal translation like The deadline will pass on Friday is understandable, but less natural in English.

Because days of the week after w usually take the accusative, not the locative, when they mean on a given day.

So:

• w piątek = on Friday
• w poniedziałek = on Monday
• w czwartek = on Thursday

This is a fixed and very common pattern.

By itself, w piątek means on Friday. Depending on context, it may refer to:

• the coming Friday
• a specific Friday already understood in context

So the sentence itself does not force this Friday, but in real use that is often what is meant.

Yes. Polish word order is flexible.

The neutral version is:

• Termin na odstąpienie od umowy upłynie w piątek.

Other possible orders include:

• W piątek upłynie termin na odstąpienie od umowy.
• Termin na odstąpienie od umowy w piątek upłynie. — possible, but less natural

Putting w piątek first gives more emphasis to when it happens.

Yes, it sounds fairly formal, especially because of:

• termin
• odstąpienie od umowy

This is the kind of language you would expect in:

• legal notices
• consumer rights information
• official emails
• contract terms

In everyday speech, people might use simpler wording, depending on the context.

A less formal version might be something like:

• Możesz odstąpić od umowy tylko do piątku. = You can withdraw from the contract only until Friday.
• Termin rezygnacji mija w piątek. = The cancellation deadline is Friday / expires on Friday.

But in legal or official contexts, Termin na odstąpienie od umowy upłynie w piątek is very natural.

Not exactly, but it functions like a phrase that specifies what kind of deadline it is.

The structure is:

• termin = head noun
• na odstąpienie od umowy = prepositional phrase modifying termin

So it works similarly to:

• deadline for withdrawal from the contract

It is not an adjective grammatically, but it plays a similar descriptive role.

Sometimes yes, but the nuance changes.

• Termin minie w piątek is understandable and fairly natural.
• Termin upłynie w piątek sounds a bit more formal and official.

Both can mean the deadline will pass/expire, but upłynie fits legal or formal wording especially well.

Here are the key dictionary forms:

• termin → termin
• na → na
• odstąpienie → odstąpienie
• od → od
• umowy → umowa
• upłynie → upłynąć
• w → w
• piątek → piątek

This can help you recognize the sentence even though some words appear in inflected forms.
