Pokrytí je tady dobré.

Pokrytí is a noun, and it is neuter in Czech.

That matters because adjectives describing it must also be in the neuter form. That is why the sentence uses dobré, not dobrý or dobrá.

Because dobré agrees with the noun pokrytí.

In Czech, adjectives change form to match the noun’s gender, number, and case.
Here:

• pokrytí = neuter singular
• so the adjective must also be neuter singular
• therefore: dobré

Compare:

• dobrý = masculine
• dobrá = feminine
• dobré = neuter

Je is the 3rd person singular form of the verb být (to be), so it means is.

In this sentence, it links the subject and the description:

• Pokrytí = the subject
• je = is
• dobré = good

So structurally it works like:

• Coverage is good here.

Unlike some languages, Czech normally keeps the verb to be in this kind of sentence.

Yes. Tady means here.

You can often also use zde, which also means here, but there is a difference in tone:

• tady = more common in everyday speech
• zde = more formal, written, or official-sounding

So Pokrytí je tady dobré sounds natural in normal conversation.

Very often, yes.

In real life, pokrytí is commonly used for things like:

• mobile signal coverage
• internet coverage
• network coverage
• general area coverage

So this sentence could easily be said when talking about phone signal, for example. The exact type of coverage usually comes from context.

Because dobře is an adverb meaning well, while dobré is an adjective meaning good.

Here, Czech is describing the noun pokrytí, so it needs an adjective:

• dobré pokrytí = good coverage

If you said Pokrytí je tady dobře, that would sound wrong because dobře does not agree with the noun and is not the form needed here.

Yes. Czech word order is more flexible than English word order.

The basic sentence Pokrytí je tady dobré is natural, but you may also hear other versions, such as:

• Tady je pokrytí dobré.
• Dobré je tady pokrytí.

These can sound more marked or emphasize different parts of the sentence.

In the original sentence, the focus is fairly neutral: it simply states that the coverage here is good.

Because Czech does not have articles like a or the.

So pokrytí can mean:

• coverage
• the coverage

You understand which one is meant from context.

That is completely normal in Czech.

A simple pronunciation guide is:

PO-kri-tee ye TA-dih DO-breh

A few useful points:

• Czech stress usually falls on the first syllable of each word.
• ř in pokrytí is not present here, so this word is easier than many Czech words.
• je sounds roughly like ye
• é is a long vowel

So:

• pokrytí → stress on po
• tady → stress on ta
• dobré → stress on do

It is singular.

That is why the verb is je (is) rather than jsou (are), and the adjective is singular as well.

So the whole sentence is singular:

• Pokrytí je tady dobré. = Coverage is good here.

Yes. Tu can also mean here, and Pokrytí je tu dobré is natural.

Very roughly:

• tady = here
• tu = here
• zde = here, but more formal

In everyday speech, both tady and tu are common. The difference is usually small and often just a matter of style or regional preference.
