Jeśli kwota jest już wpłacona, możemy wrócić do domu.

Jeśli means if. It introduces a condition:

• Jeśli kwota jest już wpłacona = If the amount has already been paid/deposited

This is a very common way to build conditional sentences in Polish.

You may also see jeżeli, which means the same thing but sounds a bit more formal or fuller:

• Jeśli kwota jest już wpłacona...
• Jeżeli kwota jest już wpłacona...

Both are correct.

Kwota means amount or sum of money.

It is feminine, singular, and here it is in the nominative case because it is the subject of the clause:

• kwota jest wpłacona = the amount is paid/deposited

Related words:

• suma = sum
• opłata = fee/payment
• pieniądze = money

But kwota specifically refers to a numerical amount.

This is a very common Polish structure: być + past passive participle.

So:

• jest wpłacona literally means something like is paid/deposited
• in natural English, this often becomes has been paid or is already paid

It focuses on the state/result, not on who performed the action.

Compare:

• Kwota jest już wpłacona.
  = The amount is already paid / has already been paid.
  Focus: the payment is completed.

• Ktoś już wpłacił kwotę.
  = Someone has already paid the amount.
  Focus: the doer of the action.

So the original sentence sounds natural when the important thing is that the money has already reached the account.

Because wpłacona agrees with kwota, which is a feminine singular noun.

The participle changes like an adjective:

• masculine: wpłacony
• feminine: wpłacona
• neuter: wpłacone

Examples:

• przelew jest zrobiony = the transfer is done
• kwota jest wpłacona = the amount is paid
• konto jest założone = the account is opened

So wpłacona matches the gender and number of kwota.

Wpłacona comes from the verb wpłacić, which means to pay in, to deposit, or to transfer money in.

So:

• wpłacić pieniądze = to pay in / deposit money
• kwota wpłacona = amount paid in / deposited amount

The verb wpłacić is perfective, which means it refers to a completed action. That fits well here, because the sentence says the payment has already been completed.

Its imperfective partner is wpłacać:

• wpłacać = to be paying in / to pay in regularly
• wpłacić = to pay in once, successfully, completely

Już means already.

It shows that the action is completed by now:

• jest już wpłacona = is already paid / has already been paid

Without już, the sentence would still make sense:

• Jeśli kwota jest wpłacona, możemy wrócić do domu.

But już adds the idea that this has happened by this point.

In Polish, już often appears before the part you want to highlight, and its placement is quite flexible:

• kwota jest już wpłacona
• kwota już jest wpłacona

The first version sounds more natural here.

Because wrócić is the perfective verb meaning to return / to go back as a completed action.

After możemy (we can), Polish often uses the infinitive that best matches the meaning:

• możemy wrócić = we can go back / we can return
  Focus: a single completed return

• możemy wracać = we can be returning / we can start heading back / we can return repeatedly
  Different nuance

In this sentence, the idea is: once the condition is met, we are free to go home now. That is why wrócić is the natural choice.

Because the preposition do requires the genitive case.

The noun dom changes in the genitive singular to domu:

• nominative: dom
• genitive: domu

So:

• do domu = to home / homeward
• more naturally in English: home

This is a fixed and very common pattern:

• iść do domu = to go home
• wrócić do domu = to return home
• jechać do domu = to drive/go home

Because the sentence begins with a subordinate clause introduced by jeśli.

Polish normally separates this kind of clause with a comma:

• Jeśli kwota jest już wpłacona, możemy wrócić do domu.

If the order changes, the comma is still used:

• Możemy wrócić do domu, jeśli kwota jest już wpłacona.

This is more consistent in Polish than in English, where commas in if-sentences can depend more on word order and style.

Yes, Polish word order is fairly flexible, though some versions sound more natural than others.

Natural versions include:

• Jeśli kwota jest już wpłacona, możemy wrócić do domu.
• Możemy wrócić do domu, jeśli kwota jest już wpłacona.

You could also move już:

• Jeśli kwota już jest wpłacona, możemy wrócić do domu.

That is understandable, but jest już wpłacona is usually the smoother, more standard order.

Because Polish has case endings and agreement, word order often changes emphasis rather than basic meaning.

It sounds neutral to slightly formal, mostly because of the vocabulary:

• kwota is a fairly official/financial word
• wpłacona also sounds administrative or financial

In everyday casual speech, people might say something less formal depending on the context, for example:

• Jeśli pieniądze są już wpłacone, możemy wrócić do domu.
• Jeśli już zapłaciliśmy, możemy wrócić do domu.

But the original sentence is perfectly natural, especially in contexts involving payments, transfers, invoices, fees, or bank transactions.

Sometimes, but not always with exactly the same meaning.

• jeśli = if
  This is the clearest conditional word.

• gdy / kiedy = when
  These can sometimes sound like the event is expected to happen rather than uncertain.

Compare:

• Jeśli kwota jest już wpłacona, możemy wrócić do domu.
  = If the amount has already been paid, we can go home.

• Gdy kwota jest już wpłacona, możemy wrócić do domu.
  = When the amount has already been paid, we can go home.

The second version can suggest more of a general rule or a more expected situation. For a straightforward condition, jeśli is usually the best choice.
