Kytarista hraje moc dobře.

Kytarista means guitarist or guitar player. It is a noun for a person, like English pianist, violinist, etc.

• kytara = guitar
• kytarista = guitarist

Czech often uses endings like -ista for professions, roles, or people associated with something.

It is in the nominative singular, because it is the subject of the sentence — the person doing the action.

So in:

Kytarista hraje moc dobře.

the guitarist is the one who plays, so kytarista is nominative.

Also, kytarista is a masculine animate noun.

Hraje is the 3rd person singular present tense of hrát (to play).

It matches the subject kytarista, which is singular:

• já hraju / hraji = I play
• ty hraješ = you play
• on / ona hraje = he / she plays
• my hrajeme = we play
• vy hrajete = you play
• oni hrají / hrajou = they play

Because kytarista = he / the guitarist in a grammatical sense, Czech uses hraje.

Yes. Hrát can mean to play in several senses, including:

• to play music / an instrument
• to play a game
• to act / perform in some contexts

In this sentence, because the subject is kytarista (guitarist), the meaning is clearly to play music.

Because the sentence needs an adverb, not an adjective.

• dobrý / dobrá / dobré = good → adjective, used to describe a noun
• dobře = well → adverb, used to describe a verb

Here dobře describes how he plays:

• Kytarista je dobrý. = The guitarist is good.
• Kytarista hraje dobře. = The guitarist plays well.

So dobře is the correct form.

Here moc means very or really.

So:

• dobře = well
• moc dobře = very well / really well

In everyday Czech, moc is extremely common and natural.

Usually, yes in everyday speech.

Both are correct:

• moc dobře = very well, really well
• velmi dobře = very well

But moc dobře sounds more conversational and common in spoken Czech, while velmi dobře can sound a bit more formal or careful.

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

So kytarista can mean:

• a guitarist
• the guitarist

The exact meaning depends on context.

In a standalone sentence like this, English might translate it as either:

• The guitarist plays very well.
• A guitarist plays very well.

Usually the guitarist sounds more natural in translation, but Czech itself does not mark that difference with an article.

Yes. Czech word order is more flexible than English because the grammar endings help show who does what.

The basic neutral order here is:

Kytarista hraje moc dobře.

But other orders are possible, depending on emphasis:

• Moc dobře hraje kytarista.
• Hraje moc dobře.
• Dobře hraje kytarista.

These alternatives can sound more marked or poetic, or they may emphasize a particular part of the sentence. For a learner, the original order is the safest and most neutral.

It is pronounced approximately like DOB-zheh, though that is only a rough guide.

A few important points:

• ře contains the Czech sound ř, which is famous for being difficult
• ž sounds like the s in measure
• in dobře, the cluster is pronounced roughly as bř
  • e, but many learners first hear it as something like bzhe

A simple learner-friendly approximation is:

dobře ≈ DOB-zheh

That is not perfect Czech pronunciation, but it is a useful start.

Roughly:

ki-ta-RIS-ta

More specifically:

• ky sounds somewhat like ki, but Czech y is its own vowel
• stress in Czech normally falls on the first syllable, so: KY-ta-ris-ta

A helpful approximation for English speakers is:

KY-ta-ris-ta

Grammatically, kytarista is a masculine noun, and it usually refers to a male guitarist.

For a female guitarist, Czech often uses:

kytaristka

So:

• Kytarista hraje moc dobře. = The male guitarist plays very well.
• Kytaristka hraje moc dobře. = The female guitarist plays very well.

In some contexts, masculine forms can be used more generally, but the basic meaning of kytarista is masculine.

Yes. That means The guitarist plays the guitar.

Compare:

• Kytarista hraje moc dobře. = The guitarist plays very well.
• Kytarista hraje na kytaru. = The guitarist plays the guitar.

With musical instruments, Czech often uses:

hrát na + accusative

For example:

• hrát na kytaru = to play the guitar
• hrát na piano = to play the piano
• hrát na housle = to play the violin

In your sentence, the instrument is not stated because it is already obvious from kytarista.
