Konsument ma prawo do odstąpienia.

Because Polish uses the fixed expression mieć prawo do + noun to mean to have the right to ....

• ma = has
• prawo = right
• do odstąpienia = to withdraw / to cancellation / to rescission depending on context

So ma prawo do ... is the natural Polish structure here. Using jest would not fit this meaning.

Konsument is in the nominative singular because it is the subject of the sentence.

You can tell because it is the person or thing that has the right:

• Konsument = the consumer
• ma = has

So the basic subject form is used.

After the preposition do, Polish normally uses the genitive case.

That is why you get:

• odstąpienie → nominative
• odstąpienia → genitive

So in this sentence:

• prawo do odstąpienia

literally follows the pattern right to withdrawal.

This is a very common structure in Polish:

• prawo do informacji = the right to information
• prawo do reklamacji = the right to make a complaint
• prawo do zwrotu = the right to a return

Odstąpienie is a verbal noun formed from the verb odstąpić.

In legal or consumer language, it often means:

• withdrawal
• cancellation
• rescission
• backing out of an agreement, especially odstąpienie od umowy = withdrawal from a contract

So do odstąpienia does not mean a physical movement away from something. In this kind of sentence it is legal language.

Because after prawo do, Polish usually takes a noun, not an infinitive.

English often says:

• the right to cancel
• the right to withdraw

But Polish commonly prefers:

• prawo do odstąpienia
• literally: the right to withdrawal

This is one of those places where Polish grammar works differently from English.

Yes, it sounds formal and especially legal/consumer-protection related.

Words like konsument and odstąpienie are common in:

• contracts
• regulations
• return policies
• legal texts
• official consumer information

In everyday speech, people might say something more direct, such as:

• Klient może zrezygnować.
• Można odstąpić od umowy.

But in legal Polish, Konsument ma prawo do odstąpienia is very natural.

Grammatically, yes. But the meaning and tone are slightly different.

• konsument = consumer in a legal sense
• klient = customer/client

In legal texts, konsument is often chosen very deliberately, because it refers to a protected legal category. So if the context is consumer law, konsument is usually the better word.

They are related, but not identical in emphasis.

• Konsument ma prawo do odstąpienia
  = The consumer has the right to withdraw
  This stresses a legal right.

• Konsument może odstąpić
  = The consumer may withdraw / can withdraw
  This stresses possibility/permission.

In legal writing, ma prawo do can sound stronger and more precise, because it explicitly states an entitlement.

Yes, Polish word order is fairly flexible, but not all versions sound equally natural.

The neutral order is:

• Konsument ma prawo do odstąpienia.

You could also see:

• Prawo do odstąpienia ma konsument.

This version puts more emphasis on konsument or sounds more contrastive, as if distinguishing the consumer from someone else.

For a learner, the original order is the safest and most neutral.

A rough pronunciation guide is:

od-stom-PYE-nya

A few useful points:

• Polish stress is usually on the second-to-last syllable, so here it falls on pie.
• The letter ą is a nasal vowel, but before p it is often pronounced something like om in actual speech.
• The ending -nia sounds roughly like nya.

So odstąpienia is often heard approximately as: od-stom-PYE-nya

Prawo is neuter singular.

That matters because adjectives or past-tense forms would need to agree with it in gender and number. In this sentence, there is no adjective modifying prawo, so you do not see much agreement yet.

Still, it is useful to know:

• to prawo = this right / this law
• nowe prawo = a new law/right

Also, be aware that prawo can mean both law and right, depending on context. Here it means right.

It is singular genitive.

The base form is:

• odstąpienie = nominative singular

After do, it becomes:

• odstąpienia = genitive singular

So the phrase refers to the act/right of withdrawal in a general sense, not to multiple withdrawals.

Yes, very often there is an implied legal object, especially od umowy (from the contract/agreement).

A fuller version might be:

• Konsument ma prawo do odstąpienia od umowy.

In many legal or commercial contexts, the shorter sentence is used because the surrounding text already makes clear what the consumer may withdraw from.
