Wyłączenie odpowiedzialności jest w polisie.

Because odpowiedzialności is in the genitive singular of odpowiedzialność (responsibility / liability).

In wyłączenie odpowiedzialności, the noun wyłączenie (exclusion) commonly takes another noun in the genitive, just like English exclusion of liability.

So the structure is:

• wyłączenie = exclusion
• odpowiedzialności = of liability

This is a very common Polish pattern:

• zakaz palenia = prohibition of smoking / no smoking
• potwierdzenie rezerwacji = confirmation of the reservation
• ograniczenie prędkości = speed limit, literally limitation of speed

So odpowiedzialności is not the subject here; it depends on wyłączenie.

Wyłączenie is in the nominative singular, because it is the subject of the sentence.

The basic structure is:

• Wyłączenie odpowiedzialności = the liability exclusion / exclusion of liability
• jest = is
• w polisie = in the policy

So literally:

Wyłączenie odpowiedzialności | jest | w polisie
subject | verb | location

Also, wyłączenie is a neuter noun, which is typical for nouns ending in -enie.

Because the preposition w (in) takes the locative case when it describes location.

Here, w polisie means in the policy, so polisa changes to the locative singular:

• nominative: polisa
• locative: w polisie

This is the normal pattern after w when you mean in somewhere:

• w domu = in the house
• w książce = in the book
• w umowie = in the contract
• w polisie = in the policy

So the ending changes because Polish marks the relationship with case, not just with the preposition.

Here polisa means insurance policy.

That matters because an English speaker might see polisa and wonder whether it is related to police. It is not. In this sentence, it is a legal/insurance word.

Examples:

• polisa ubezpieczeniowa = insurance policy
• numer polisy = policy number
• w polisie = in the policy

So the sentence is talking about something written or included in an insurance policy document.

Usually w polisie means in the policy, referring to the contents of the policy document.

If you want to emphasize something physically written on a document, Polish sometimes uses na in other contexts, but with contracts, policies, and texts, w is the normal choice when talking about what is included in them.

So:

• w polisie = in the policy, as part of its contents

For a learner, the safest choice here is definitely w polisie.

In a normal full sentence, yes.

Jest is the 3rd person singular present tense of być (to be), and it means is.

So:

• Wyłączenie odpowiedzialności jest w polisie. = The exclusion of liability is in the policy.

Polish sometimes omits jest in certain informal, headline-like, or stylistically compressed contexts, especially in equational sentences, but in a standard sentence like this, jest is the natural form.

So for learners, it is best to treat jest here as required.

Yes. Polish word order is more flexible than English because case endings show the grammatical relationships.

The sentence:

• Wyłączenie odpowiedzialności jest w polisie.

could also be rearranged, for example:

• W polisie jest wyłączenie odpowiedzialności.

Both are grammatical, but the emphasis changes slightly.

Roughly:

• Wyłączenie odpowiedzialności jest w polisie.
  Focuses first on the exclusion of liability
• W polisie jest wyłączenie odpowiedzialności.
  Focuses first on where it is: in the policy

English is much stricter about word order, so this is something learners often notice.

It is a formal/legal expression meaning something like:

• exclusion of liability
• liability exclusion
• sometimes, depending on context, disclaimer of liability

It is not an everyday casual phrase. It sounds like legal, insurance, or contractual language.

The key nuance is that it refers to a clause or provision saying that someone is not responsible in certain situations.

So even if the general meaning is already known, it is useful to recognize that this is a fixed, formal phrase in Polish.

It can mean both, depending on context.

• In everyday language, odpowiedzialność often means responsibility
• In legal, insurance, and business contexts, it often means liability

In this sentence, because of polisie and the formal phrase wyłączenie odpowiedzialności, the best reading is liability.

So:

• odpowiedzialność = responsibility / liability
• here: liability

Wyłączenie is a noun formed from the verb wyłączyć.

Very roughly:

• wyłączyć = to exclude / to switch off / to disconnect, depending on context
• wyłączenie = exclusion / switching off / disconnection

In this sentence, it clearly has the legal meaning exclusion.

This is a very common pattern in Polish:

• verb + noun in -enie / -anie

For example:

• ograniczyć → ograniczenie = limit / limitation
• potwierdzić → potwierdzenie = confirmation
• wyłączyć → wyłączenie = exclusion

So recognizing -enie nouns can help learners read formal Polish.

A rough pronunciation guide is:

vy-WON-che-nyeh od-po-vyed-jal-NO-shchee yest f po-LEE-syeh

A few useful points:

• wy often sounds roughly like vɨ to English ears
• cz sounds like ch in chop
• ci before a vowel often sounds like a soft chi / tshi
• w is pronounced like English v
• j is pronounced like English y
• si before a vowel is soft, so polisie has a soft ś sound

More word by word:

• Wyłączenie ≈ vy-WON-che-nye
• odpowiedzialności ≈ od-po-vyed-jal-NO-shchi
• jest ≈ yest
• w polisie is pronounced roughly f po-LEE-sye, because w before p is devoiced and sounds like f

That last point is especially useful: although it is spelled w, in speech it often sounds like f before a voiceless consonant such as p.

Yes, it is grammatical and natural, especially in a formal or insurance-related context.

That said, depending on context, a Polish speaker might also say:

• W polisie jest wyłączenie odpowiedzialności.
• Polisa zawiera wyłączenie odpowiedzialności. = The policy contains an exclusion of liability.
• W polisie znajduje się wyłączenie odpowiedzialności. = There is an exclusion of liability in the policy.

Your sentence sounds correct and fairly neutral, though definitely on the formal side because of the vocabulary.
