Kdo je veterinář?

Kdo means who.

It is the standard Czech interrogative pronoun used for asking about a person:

• Kdo je veterinář? = Who is the veterinarian / Who is a veterinarian?
• Kdo to je? = Who is that?

A useful thing to remember is that kdo is only for people, not things.

Je means is.

It is the 3rd person singular form of the verb být = to be.

So:

• já jsem = I am
• ty jsi / seš = you are
• on/ona/ono je = he/she/it is

In Kdo je veterinář?, je matches the singular idea of who: Who is ...?

This is actually very close to English word order.

Czech does not usually form questions by inverting the subject and verb the way English does in many sentences. Instead, Czech often just uses:

• a question word like kdo,
• normal verb placement,
• and rising intonation in speech.

So Kdo je veterinář? is the natural Czech structure.

Literally, the order is:

• Kdo = who
• je = is
• veterinář = veterinarian

Czech has no articles, so it does not have direct equivalents of English a/an and the.

That means veterinář can mean:

• a veterinarian
• the veterinarian

The exact meaning depends on context.

So Kdo je veterinář? could mean either:

• Who is a veterinarian?
• Who is the veterinarian?

If you want to make it more clearly specific, Czech often uses words like ten / ta / to:

• Kdo je ten veterinář? = Who is the veterinarian / Who is that veterinarian?

Here veterinář is in the nominative case.

After the verb být (to be), Czech commonly uses the nominative when identifying someone’s role, identity, or profession:

• On je učitel. = He is a teacher.
• Ona je lékařka. = She is a doctor.
• Kdo je veterinář? = Who is a veterinarian / the veterinarian?

So this is a very normal pattern: [someone] + je + nominative noun

It can mean either one.

Because Czech has no articles, this sentence is naturally ambiguous without context.

Possible situations:

• In a group of people, you ask Kdo je veterinář? = Who is a veterinarian?
• At an animal clinic, pointing to a role, it could mean Who is the veterinarian?

If you need to be more specific, Czech can add context words:

• Kdo je ten veterinář? = Who is the veterinarian? / Who is that vet?
• Kdo z vás je veterinář? = Which of you is a veterinarian?

A rough pronunciation guide is:

veh-teh-rih-naarzh

A few important points:

• á is a long a sound, so hold it a little longer than plain a
• ř is the famous Czech sound that is difficult for many learners

If you cannot say ř yet, saying something close to rž or zh is often understood, even if it is not perfect.

So veterinář is approximately:

ve-te-ri-nář

with the stress on the first syllable, because Czech stress is usually on the first syllable of the word:

VE-te-ri-nář

Yes, veterinář is the usual masculine form.

The feminine form is:

veterinářka

So:

• On je veterinář. = He is a veterinarian.
• Ona je veterinářka. = She is a veterinarian.

In the question Kdo je veterinář?, the masculine form can sometimes be used in a general sense, especially if the speaker does not yet know who the person is. But if you know the person is a woman, Kdo je veterinářka? may be appropriate in the right context.

In this basic sentence, kdo stays as kdo because it is the normal dictionary form used for the subject of the question.

Czech kdo does decline in other cases, for example:

• Koho vidíš? = Whom do you see?
• Komu to dáváš? = To whom are you giving it?

But in Kdo je veterinář?, kdo is the subject, so kdo is the correct form.

A natural answer would be:

• Jan je veterinář. = Jan is a veterinarian.
• To je veterinář. = That is the veterinarian / a veterinarian.
• Já jsem veterinář. = I am a veterinarian.

If answering by pointing someone out:

• Petr je veterinář.
• Tamten muž je veterinář. = That man over there is a veterinarian.

Yes, absolutely.

Kdo je ten veterinář? sounds more specific. It usually means something like:

• Who is the veterinarian?
• Who is that veterinarian?

The word ten helps point to a specific person already known, visible, or understood from context.

Compare:

• Kdo je veterinář? = Who is a veterinarian? / Who is the veterinarian?
• Kdo je ten veterinář? = Who is that veterinarian? / Who is the specific veterinarian?

So the version without ten is more general; the version with ten is more definite.

It is neutral and completely standard.

There is nothing especially formal or informal about:

Kdo je veterinář?

You could use it in everyday speech, in class, or in writing.

What changes the tone more is the surrounding context, not the sentence itself.
