To je jedna miliarda.

To means this / that / it, depending on context.

In To je jedna miliarda, it works like This is one billion or It is one billion.

Czech to is very common in simple identifying sentences:

• To je dům. = This is a house.
• To je pravda. = That is true.

So here, to is the thing being identified.

Je is the 3rd person singular form of the verb být = to be.

So:

• je = is

That makes the sentence structure:

• To = this/it
• je = is
• jedna miliarda = one billion

So literally: This/it is one billion.

Because miliarda is a feminine noun, and the number one must agree with the gender of the noun.

Forms of one in Czech:

• jeden for masculine
• jedna for feminine
• jedno for neuter

Since miliarda is feminine, you say:

• jedna miliarda

Compare:

• jeden milion = one million
• jedna miliarda = one billion
• jedno euro = one euro

Yes. In modern usage:

• Czech milion = million = 10⁶
• Czech miliarda = billion = 10⁹
• Czech bilion = 10¹²

This is important because bilion in Czech does not mean the same thing as English billion.

So:

• one billion = jedna miliarda
• one trillion = jeden bilion in Czech

Yes, often you can.

• To je jedna miliarda.
• To je miliarda.

Both are possible, but they feel slightly different.

To je jedna miliarda explicitly says one billion.

To je miliarda can still mean it is a billion / it is one billion, especially when the number itself is the main point.

Including jedna makes the quantity fully explicit.

It is in the nominative singular.

This sentence is a basic identification sentence:

• To je X. = This is X.

In that pattern, the noun is typically in the nominative:

• To je učitel. = This is a teacher.
• To je problém. = This is a problem.
• To je jedna miliarda. = This is one billion.

So there is no special case change here.

The basic neutral order is:

• To je jedna miliarda.

That is the most natural version for a learner.

Czech word order is more flexible than English, but changing it usually changes the emphasis. For example:

• Jedna miliarda, to je hodně. = One billion, that is a lot.

For a simple statement, stick with:

• To je jedna miliarda.

A simple pronunciation guide:

• To ≈ toh
• je ≈ yeh
• jedna ≈ yed-nah
• miliarda ≈ mil-ee-yar-dah

Approximate full pronunciation:

• toh yeh yed-nah mil-ee-yar-dah

A few helpful notes:

• Czech j sounds like English y
• Czech r is rolled or tapped
• Stress in Czech usually falls on the first syllable of each word:
  • TO je JEDna miLIARda

Yes, but it depends on context.

By itself, To je jedna miliarda sounds like:

• identifying a number on a screen,
• explaining a statistic,
• reacting to an amount of money,
• teaching numbers.

For example:

• Kolik je to? To je jedna miliarda.
• Na účtu je jedna miliarda korun.

So the sentence is correct and natural, especially when pointing to or discussing a number.

It can mean either, depending on context.

Czech to is often less specific than English this and that in this kind of sentence. The exact English translation depends on the situation:

• if you are pointing at something near you: This is one billion
• if you are referring back to an idea or amount: That is one billion
• if you are identifying a value: It is one billion

So the Czech sentence itself does not force only one of those translations.

You would say:

• To je jedna miliarda korun.

Here:

• jedna miliarda = one billion
• korun = crowns/korunas

Notice that after miliarda, the counted noun changes form:

• jedna miliarda korun

This is very common with large numbers in Czech.

The basic plural form is miliardy.

Examples:

• jedna miliarda = one billion
• dvě miliardy = two billion
• tři miliardy = three billion

You may also see other forms depending on case, such as miliard, but the basic plural dictionary form is miliardy.

Yes. Jedna miliarda is just the number itself, so it can refer to many things depending on context:

• money
• people
• years
• stars
• views
• data units

For example:

• To je jedna miliarda korun. = That is one billion crowns.
• To je jedna miliarda lidí. = That is one billion people.

Without extra words, it simply means one billion.
