Debetní karta je v peněžence.

• debetní = debit
• karta = card
• je = is
• v = in
• peněžence = in the wallet / purse

So the structure is very close to English: Debit card is in wallet, with the exact English meaning supplied by context.

Because after v when it means a fixed location, Czech normally uses the locative case.

The basic dictionary form is:

• peněženka = wallet / purse

But after v for location, it changes to:

• v peněžence = in the wallet

So:

• peněženka = nominative
• v peněžence = locative singular

This is a very common pattern in Czech.

In this sentence, v means in because it describes location:

• Debetní karta je v peněžence. = The debit card is in the wallet.

With v, the important contrast is often:

• v + locative = in/inside somewhere, no movement
• movement into is usually expressed with do + genitive

For example:

• Karta je v peněžence. = The card is in the wallet.
• Dám kartu do peněženky. = I’ll put the card into the wallet.

So Czech distinguishes location and movement into more clearly than English sometimes does.

Because debetní belongs to a type of adjective that ends in -í. These adjectives often keep -í in the nominative singular across genders.

So:

• debetní karta = debit card
• moderní karta = modern card
• platební karta = payment card

Even though karta is feminine, debetní still stays debetní in this form.

It does still decline in other cases, but not in the simple dictionary-like nominative form here.

Yes, debetní karta is a normal and standard way to say debit card.

You may also see related expressions such as:

• kreditní karta = credit card
• platební karta = payment card / bank card

So debetní karta is specific and correct.

In standard Czech, yes, it is necessary here.

• Debetní karta je v peněžence. = correct
• Debetní karta v peněžence. = not a normal complete neutral sentence

Unlike some languages, Czech normally keeps the present-tense form of to be in sentences like this.

Because Czech does not have articles like English a/an and the.

So:

• karta can mean a card or the card
• peněženka can mean a wallet or the wallet

The exact meaning depends on context.

That means Debetní karta je v peněžence. could be understood as:

• The debit card is in the wallet
• A debit card is in the wallet

Usually the surrounding context tells you which one is meant.

Yes. Czech word order is more flexible than English because case endings show grammatical roles.

The neutral order here is:

• Debetní karta je v peněžence.

But you could also say:

• V peněžence je debetní karta.

That version puts more focus on where the card is.

So the word order can change for emphasis, information structure, or style, even though the basic meaning stays the same.

Because debetní karta is in the nominative case, which is the normal case for the subject.

Also, v peněžence is clearly a prepositional phrase showing location, so it cannot be the subject here.

So the sentence breaks down like this:

• Debetní karta = subject
• je = verb
• v peněžence = location phrase

The noun peněženka is a feminine noun ending in -ka. In the locative singular, this type often changes:

• -ka → -ce

So:

• peněženka
• v peněžence

This kind of consonant change is common in Czech declension. You do not always need to predict it perfectly at first; it is often best to learn the whole phrase:

• v peněžence
• v tašce
• v kabelce

Learning nouns together with common prepositional forms is very helpful.

It can correspond to either wallet or purse, depending on the speaker and context.

In Czech, peněženka is the thing you keep money, cards, and similar items in. In English, the best translation may be:

• wallet
• purse

So if the meaning has already been shown to you as wallet, that is perfectly fine.

A simple learner-friendly pronunciation guide is:

DE-beht-nee KAR-ta yeh v PEH-nye-zhen-tseh

A few useful pronunciation notes:

• Czech stress is usually on the first syllable of each word.
• ž sounds like the s in measure.
• c sounds like ts.
• ě often makes the preceding consonant sound softer, so ně sounds roughly like nye.

So peněžence is roughly:

PEH-nye-zhen-tseh

No, here the normal form is v peněžence.

Czech sometimes uses ve instead of v for easier pronunciation, especially before difficult consonant clusters, for example:

• ve škole = at school / in the school

But peněžence begins with p, which is easy to say after v, so:

• v peněžence = correct
• ve peněžence = not normal here

No. For movement into something, Czech usually uses do plus the genitive.

Compare:

• Debetní karta je v peněžence. = The debit card is in the wallet.
• Dávám debetní kartu do peněženky. = I am putting the debit card into the wallet.

So:

• v peněžence = location
• do peněženky = movement into

This is one of the most important preposition patterns to learn early.
