Tato oblast je daleko.

Because oblast is a feminine noun, and the demonstrative tato must agree with it.

In Czech, this changes by gender:

• tento = masculine
• tato = feminine
• toto = neuter

So:

• tento dům = this house
• tato oblast = this area
• toto město = this town/city

Agreement in gender is very important in Czech.

You usually have to learn the gender of each noun, but there are patterns.

Oblast is feminine even though it ends in a consonant. That may feel surprising to an English speaker, because many Czech feminine nouns end in -a, but not all of them do.

A lot of feminine nouns ending in a soft consonant follow this pattern, for example:

• kost = bone
• radost = joy
• možnost = possibility
• oblast = area/region

So oblast is simply a feminine noun you need to memorize.

It is in the nominative singular.

That is because tato oblast is the subject of the sentence:

• Tato oblast = the thing being talked about
• je daleko = is far away

So the basic structure is:

• subject
  • verb
    • complement

Here, the subject stays in the nominative.

Je is the 3rd person singular form of být, which means to be.

So:

• je = is

Czech often drops subject pronouns like he, she, it, but it does not normally drop the verb to be in a standard sentence like this.

So Tato oblast je daleko is the normal full sentence.

In standard Czech, no. That sounds incomplete or ungrammatical.

You need:

• Tato oblast je daleko.

Czech does omit to be in some special contexts, such as headlines, notes, or very colloquial fragments, but not in an ordinary neutral sentence like this.

Because daleko is being used as an adverb, not an adjective.

In this sentence, Czech expresses the idea is far away with:

• je daleko

Here daleko means far in the sense of location/distance.

If you used daleká, that would be an adjective agreeing with oblast:

• daleká oblast = a distant/remote area

That is grammatically possible, but it is a different structure. In your sentence, Czech normally prefers:

• oblast je daleko = the area is far away

Yes, here it functions as an adverbial expression meaning far away.

This is very common after být:

• Je blízko. = It is near.
• Je daleko. = It is far away.
• Je doma. = He/She is at home.

English often uses an adjective in these situations, but Czech often uses an adverb-like form.

Not necessarily. Czech can leave that unspecified, just like English can say It’s far away without saying from where.

If you want to add the reference point, you can:

• Tato oblast je daleko od města. = This area is far from the city.
• Tato oblast je daleko odsud. = This area is far from here.

Without that extra information, the sentence still works perfectly.

The normal neutral order is:

• Tato oblast je daleko.

You can change the word order in Czech, but that usually changes the emphasis.

For example:

• Daleko je tato oblast.

This is possible, but it sounds marked or emphatic, as if you are stressing far away.

For most learners, the safest choice is the standard neutral order: subject + je + daleko.

Both can mean this or that depending on context, but they are not exactly the same.

• tato is the more explicit demonstrative, like this
• ta is the basic form of that/she/the, depending on context

So:

• tato oblast = this area
• ta oblast = that area / that particular area / sometimes just the area, depending on context

If your sentence specifically means this area, then tato oblast is the clearer choice.

A common version would be:

• Ta oblast je daleko.

If you want to make the that more strongly contrastive, Czech can also use forms like tamta in some contexts:

• Tamta oblast je daleko. = That area over there is far away.

But ta oblast is often enough.

A rough pronunciation guide:

• oblast ≈ OH-blast
• daleko ≈ DAH-leh-koh
• tato ≈ TAH-toh

A few helpful points:

• Czech stress is usually on the first syllable
• a is like the a in father
• e is like e in bed, but can vary slightly
• o is like o in for, but shorter and cleaner

So the whole sentence is roughly:

• TAH-toh OH-blast yeh DAH-leh-koh

Because Czech daleko already covers the idea of far / far away.

English often says:

• is far
• is far away

Czech usually just uses:

• je daleko

So there is no need for a separate word meaning away here.

Yes. Oblast is a flexible word and can mean things like:

• area
• region
• district
• field/domain, depending on context

So the exact English translation depends on the situation. But grammatically, the Czech sentence stays the same.
