Kam jdeš po práci?

Kam asks about a destination or direction: where someone is going to.

• Kam jdeš? = Where are you going?
• Kde jsi? = Where are you?

So in this sentence, kam is used because jdeš describes movement.

Jdeš is the 2nd person singular form of jít, which means to go.

So:

• jdu = I go / I am going
• jdeš = you go / you are going
• jde = he/she/it goes

In Kam jdeš po práci?, jdeš means are you going.

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

Here, -eš in jdeš already tells you it means you singular.

So:

• Kam jdeš po práci? = normal, natural
• Kam ty jdeš po práci? = possible, but ty adds emphasis, contrast, or emotion

English needs you, but Czech usually does not.

Because the preposition po here requires the locative case.

The dictionary form is práce = work, but after po it changes to práci.

So:

• práce = work
• po práci = after work

This is a very common pattern in Czech: the preposition changes the form of the noun.

It usually means after work in this situation, often after work today.

So Kam jdeš po práci? most naturally means something like Where are you going after work?

If you wanted to ask about a habit or repeated action, Czech would often use chodit instead:

• Kam chodíš po práci? = Where do you go after work? / Where do you usually go after work?

So jdeš sounds more like a specific occasion, while chodíš sounds habitual.

Yes. Czech often uses the present tense for a planned or expected future action, especially with verbs of motion.

So Kam jdeš po práci? is literally present tense, but in natural English it is usually translated as Where are you going after work?

That is very normal Czech usage.

This is the most neutral and natural word order for this question.

• Kam comes first because it is the question word.
• jdeš follows as the verb.
• po práci adds the time context.

Czech word order is flexible, so other orders are possible, but they sound more marked or emphasize something different. For example:

• Po práci kam jdeš? puts more focus on after work
• Kam jdeš po práci? is the standard neutral version

Yes, if you are speaking:

• to more than one person, or
• to one person formally

Compare:

• Kam jdeš po práci? = informal singular
• Kam jdete po práci? = plural or formal singular

So the sentence given is informal and addressed to one person.

Yes, but the meaning changes slightly.

• jít = to go on foot
• jet = to go by vehicle

So:

• Kam jdeš po práci? = Where are you going after work? (on foot / generally as motion)
• Kam jedeš po práci? = Where are you going after work? (by car, bus, train, bike, etc.)

In standard Czech, that distinction matters.

Because Czech has no articles.

English uses words like a, an, and the, but Czech does not. The meaning is understood from context.

So po práci is simply after work, with no article needed.
