Czy introduces an indirect yes/no question. Here it means whether or if:
This czy is not the same as English conditional if in sentences like If it rains, we’ll stay home. In Polish, czy is used for questions, not conditions.
This is about aspect, which is very important in Polish.
In this sentence, the customer is asking whether they can make a payment / complete the payment by card, so zapłacić is the natural choice.
Compare:
Because Polish uses the instrumental case after many expressions meaning by means of something.
So:
In this sentence, kartą means with a card / by card.
This is very common in Polish:
Not necessarily. Kartą by itself usually just means by card, without specifying exactly what kind.
Depending on context, it could mean:
If you want to be more specific, Polish can say:
Polish often omits subject pronouns when the meaning is already clear from the verb form or context.
In może zapłacić, there is no separate word for he/she, but the sentence naturally refers back to klient.
So Polish does not need to say something like:
That version is possible, but normally unnecessary. Using on would add emphasis, and in many contexts it would sound less natural.
Klient is in the nominative singular, because it is the subject of the sentence.
So Klient pyta means The customer asks.
Pyta is present tense, 3rd person singular, from pytać = to ask.
So:
In Polish, the present tense can often match either simple present or present continuous in English, depending on context. So pyta could correspond to:
Yes, Polish word order is more flexible than English, although some orders sound more natural than others.
The neutral version is:
You could also hear:
But inside the reported clause, czy może zapłacić kartą is already the most natural standard order.
Polish changes word order mostly for:
So while word order can move, not every rearrangement sounds equally natural.
No, it is an indirect question.
A direct question would be:
But in your sentence, the speaker is reporting the question:
So the whole sentence is a statement, even though it contains a question clause.
Because móc works like a modal verb in Polish, similar to can in English.
So the pattern is:
Here:
Together:
This is the normal structure in Polish.
Yes, klient is the masculine noun meaning male customer or sometimes customer in a general sense.
If you want to clearly say female customer, Polish uses:
So:
In many real contexts, klient may be used generically, but klientka is the specifically feminine form.
A rough pronunciation guide is:
A few useful notes:
So the whole sentence is roughly:
KLYENT PIH-ta, chi MO-zhe za-PWA-chich KAR-ton
You might see that kind of translation sometimes, but in natural English, whether is better here:
English also allows if in this kind of sentence:
But in Polish, the word is czy, specifically marking an indirect yes/no question. So it is best to understand it as whether / if in the question sense, not the conditional sense.
