Jsem sice začátečník, ale tančím podle choreografie.

Czech often leaves out subject pronouns because the verb ending already tells you who the subject is.

• jsem = I am
• tančím = I dance

So Já jsem sice začátečník... is possible, but já is not necessary. You would usually add já only for emphasis or contrast, for example if you want to stress I in particular.

This is a very common Czech pairing that expresses contrast.

• sice = admittedly / it is true that / granted
• ale = but

So the pattern sice ..., ale ... means something like:

• admittedly ..., but ...
• it’s true that ..., but ...
• I may be ..., but ...

In this sentence, it softens the first statement and sets up the contrast: I may be a beginner, but I dance according to the choreography.

That is the normal structure. Sice signals that the speaker is conceding something, and ale introduces the contrasting point.

So:

• first clause: concession → Jsem sice začátečník
• second clause: contrast → ale tančím podle choreografie

This pairing is very natural in Czech.

Because Czech has no articles like a, an, or the.

So začátečník can mean:

• a beginner
• the beginner

The exact meaning depends on context. In this sentence, English naturally uses a beginner, but Czech does not need a separate word for that.

After být (to be), Czech can use either the nominative or the instrumental for the predicate noun, depending on style and nuance.

Here, Jsem začátečník is very natural and common for simple identification: I am a beginner.

You may also see jsem začátečníkem, but that usually sounds more formal, more bookish, or sometimes more temporary/situational.

For everyday speech, jsem začátečník is the form most learners should remember first.

Because of the verb endings.

• jsem is the 1st person singular form of být (to be)
• tančím is the 1st person singular present form of tančit (to dance)

So both verbs clearly refer to I. Czech verb endings carry a lot of information, which is why subject pronouns are often omitted.

Podle requires the genitive case.

So in podle choreografie, the noun choreografie is in the genitive singular.

This is a useful rule to memorize:

• podle + genitive = according to / based on / following

Because some Czech nouns have the same form in more than one case.

For choreografie:

• nominative singular: choreografie
• genitive singular: choreografie

So after podle, the form is genitive, but it happens to look identical to the nominative.

That is completely normal in Czech declension.

It means something like:

• according to the choreography
• following the choreography
• in line with the choreography

In this sentence, it suggests that the speaker dances by following an established sequence of movements rather than improvising.

A woman would most naturally say:

Jsem sice začátečnice, ale tančím podle choreografie.

• začátečník = masculine form
• začátečnice = feminine form

In some contexts, Czech can use masculine forms more generally, but when speaking about herself, a woman would normally use začátečnice.

Because ale means but, and in Czech it is normally preceded by a comma when it joins contrasting clauses or sentence parts.

So:

Jsem sice začátečník, ale tančím podle choreografie.

The comma is standard and expected here.

Yes. Czech word order is flexible, though not random.

A very common alternative would be:

Sice jsem začátečník, ale tančím podle choreografie.

This means essentially the same thing. Putting sice earlier is also very natural.

The original sentence is fine too. The choice is mostly about emphasis and rhythm rather than a big change in meaning.

Because the sentence describes an ongoing ability, habit, or general way of dancing, not one completed dance event.

• tančit = imperfective, used for ongoing/repeated action
• zatančit = perfective, more like to dance something / perform a dance once, successfully, completely

Here the meaning is general: I dance according to the choreography, so tančím is the right choice.
