Tato hvězda je daleko.

• tato = this (feminine singular, because it refers to hvězda)
• hvězda = star
• je = is
• daleko = far / far away

So the structure is very straightforward: this star is far away.

Because hvězda is a feminine noun.

In Czech, words like this have to agree with the noun in gender, number, and case.

For tento = this, the nominative singular forms are:

• masculine: tento
• feminine: tato
• neuter: toto

Since hvězda is feminine singular, you need tato.

A very common clue is the ending -a. Many Czech nouns ending in -a are feminine, and hvězda is one of them.

That matters because other words in the sentence must match it:

• tato hvězda = feminine singular
• je = singular verb form

So the gender of hvězda affects the form of the demonstrative.

It is in the nominative, because it is the subject of the sentence.

The sentence is basically:

• Tato hvězda = the subject
• je daleko = what is being said about the subject

Because tato goes with hvězda, it is also in the nominative feminine singular.

In normal Czech, je is needed here.

It is the 3rd person singular present form of být = to be.

So:

• Tato hvězda daleko is not standard Czech.
• Tato hvězda je daleko is correct.

Czech usually keeps the present-tense form of to be in sentences like this.

Because daleko is an adverb, while daleká is an adjective.

Here, Czech uses the pattern:

• být daleko = to be far away

So daleko describes distance from something, not a quality directly attached to the noun.

Compare:

• Tato hvězda je daleko. = This star is far away.
• To je daleká hvězda. = That is a distant star.

In the first sentence, daleko is the natural choice.

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

That means Czech often expresses definiteness through context, word order, or words like tento / tato / toto.

So in this sentence:

• tato hvězda already tells you which star is meant: this star

There is no separate word for the.

Yes, but the nuance changes a bit.

• tato hvězda = standard, clear this star
• ta hvězda = can mean that star, but in real usage it can also sometimes function a bit like the/that one, depending on context
• tahle hvězda = common colloquial Czech for this star

So Tato hvězda je daleko is a good neutral standard sentence.

The given order is the most neutral and natural one:

• Tato hvězda je daleko.

Czech word order is more flexible than English, but changes usually affect emphasis.

For example:

• Daleko je tato hvězda. = puts extra focus on far
• Tato hvězda je daleko. = neutral statement

So yes, other orders are possible, but the original is the best basic version to learn first.

Yes, it can look tricky at first.

A rough pronunciation guide:

• tato ≈ TAH-to
• hvězda ≈ HVYEZ-da
• je ≈ ye
• daleko ≈ DA-le-ko

A few helpful points:

• Czech stress is usually on the first syllable of each word.
• ě often makes the preceding consonant softer and is pronounced roughly like ye after many consonants.
• The beginning hv- is a real consonant cluster, so hvězda starts with something like hv
  • yez.

A rough full pronunciation is:

TAH-to HVYEZ-da ye DA-le-ko

Not only, but physical distance is the basic meaning.

In a sentence like Tato hvězda je daleko, the normal reading is literal: the star is far away in space.

But daleko can also be used more broadly in other contexts, for example to mean something is far off in time, progress, or degree. Here, though, the literal meaning is the obvious one.

You would say:

Tyto hvězdy jsou daleko.

Changes:

• tato → tyto = these
• hvězda → hvězdy = stars
• je → jsou = are
• daleko stays daleko

So this sentence is a good model for seeing how agreement works in Czech.
