Částka je milion korun.

Here částka means amount or sum. It is a general word for a monetary figure.

It is not exactly the same as cena, which usually means price. So:

• částka = amount / sum
• cena = price

In this sentence, částka is the subject: The amount is...

Je is the 3rd person singular present form of být, meaning to be.

So:

• částka je... = the amount is...

Czech normally does use je in this kind of present-tense sentence. You cannot usually leave it out.

Because after milion, the noun that follows goes into the genitive plural.

So:

• koruna = one crown
• koruny = 2, 3, 4 crowns
• korun = 5+ crowns, and also after words like milion

That is why milion korun is correct.

This is one of the most important number patterns in Czech.

Grammatically, milion behaves mostly like a noun.

More specifically, it is a masculine inanimate noun. That is why it can decline like a noun and why it takes genitive plural after it:

• milion korun
• bez milionu korun = without a million crowns

So even though it expresses a number, it acts like a noun in many grammatical ways.

Yes. Jeden milion korun is grammatically correct.

But in many contexts, Czech simply says milion korun without jeden, because milion already naturally means one million unless another number is added.

So both are possible:

• milion korun
• jeden milion korun

The version without jeden is very common and natural.

The cases are:

• částka = nominative singular
  It is the subject of the sentence.

• milion = nominative singular
  It is the main word in the predicate after je.

• korun = genitive plural
  It depends on milion.

So the structure is basically:

• Částka = subject
• je milion korun = predicate saying what the amount is

Because Czech has no articles.

English says:

• the amount
• an amount
• a million

Czech does not use separate words for the or a/an. The meaning is understood from context.

So Částka je milion korun can mean something like The amount is a million crowns depending on context.

A rough pronunciation guide is:

CHAAST-kah ye MI-lee-on KO-run

A few useful points:

• Č sounds like ch in chess
• á is a long vowel
• j is pronounced like English y
• Czech stress usually falls on the first syllable of each word

So:

• Částka → stress on ČÁS-
• milion → stress on MI-
• korun → stress on KO-

Yes, Czech word order is more flexible than English word order. But different word orders can sound more or less natural depending on emphasis.

Částka je milion korun is a natural neutral sentence if you are talking about the amount and then stating what it is.

Other possibilities may be used for emphasis, but they can sound marked or stylistically different. For example:

• Částka činí milion korun. = The amount comes to one million crowns.
  This is more formal.

So the original sentence is fine and natural, especially as a straightforward statement.

Usually yes. Koruna means crown and in modern Czech contexts it normally refers to the Czech crown (Czech koruna, CZK).

So milion korun usually means one million Czech crowns unless another type of crown currency is clear from context.

Yes, it is grammatical and natural.

That said, depending on style, Czech speakers might also say:

• Je to milion korun. = It’s one million crowns.
• Částka činí milion korun. = The amount comes to one million crowns.
  This sounds more formal or official.

So Částka je milion korun is correct, but the most natural choice can depend on the situation.
