Její muž je veterinář.

Její means her.

It is a possessive pronoun, used to show ownership or relationship: her husband.

A useful thing to know is that její refers to a female owner. In other words, the person who has the husband is female.

Compare:

• její muž = her husband
• jeho muž = his man / his husband depending on context

Also, její does not change here because it agrees with the possessed noun in the right way for this sentence: muž is masculine singular in the nominative.

Yes. Muž can mean both man and husband, depending on context.

In this sentence, Její muž je veterinář, the natural meaning is Her husband is a veterinarian.

If you wanted to be more explicitly unambiguous, Czech also has:

• manžel = husband
• manželka = wife

So:

• její muž often means her husband
• ten muž means that man

Context usually makes the meaning clear.

Je means is.

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

So:

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

In Její muž je veterinář, je matches muž because muž is a singular subject: Her husband is...

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

So:

• veterinář can mean a veterinarian or the veterinarian
• the exact meaning depends on context

That is completely normal in Czech.

So the sentence literally looks more like:

• Her husband is veterinarian

But in natural English, we say:

• Her husband is a veterinarian

In modern Czech, after být (to be), the noun describing identity, profession, or role is often in the nominative.

So:

• Její muž je veterinář.
• On je učitel.
• Ona je lékařka.

That is standard and natural.

You may also encounter the instrumental after být, especially in some styles or contexts:

• Je veterinářem.

Both are possible, but in a simple sentence identifying someone’s profession, the nominative veterinář is very common and beginner-friendly.

A rough pronunciation guide for an English speaker is:

• Její ≈ yeh-yee
• muž ≈ moosh (but the final sound is ž, like the s in measure)
• je ≈ yeh
• veterinář ≈ veh-teh-rih-naarzh

A few sound notes:

• j in Czech is pronounced like English y in yes
• ž sounds like the s in measure
• á is a long vowel, so it is held a bit longer than a

So the whole sentence is roughly: yeh-yee moozh yeh veh-teh-rih-naarzh

This is the most neutral, basic word order:

• Její muž = subject
• je = verb
• veterinář = complement

So it follows a very familiar pattern: Subject + is + profession

Czech word order is more flexible than English, so other orders are possible for emphasis, for example:

• Veterinář je její muž. = Her husband is the veterinarian / emphasis on veterinarian
• Je veterinář její muž? = Is her husband a veterinarian?

But the original order is the normal straightforward statement.

Veterinář is a masculine noun, so it is used for a male veterinarian.

If the veterinarian is a woman, Czech usually uses:

• veterinářka = female veterinarian

So:

• Její muž je veterinář. = Her husband is a veterinarian.
• Její žena je veterinářka. = Her wife is a veterinarian.
  or more naturally:
• Její manželka je veterinářka. = Her wife is a veterinarian.

Czech often marks professions by gender more clearly than English does.

Many Czech words do change a lot, yes. But její is one of those forms that can stay the same in several positions.

Here it is:

• feminine possessor: her
• with a masculine singular noun: muž

You will see její in many combinations, for example:

• její muž = her husband
• její sestra = her sister
• její auto = her car

In some other forms, related possessives can change more clearly, but její itself is often pleasantly stable for learners.

Technically yes, because muž can mean man as well as husband.

But in most everyday situations, její muž is naturally understood as her husband.

If someone specifically meant her man in the general sense, context would need to support that. Without context, a learner should usually read:

• její muž = her husband

If you want to make the subject plural, you would change the words accordingly.

For example:

• Její muži jsou veterináři. = Her husbands / men are veterinarians.

But that sounds unusual because her husbands is not the normal intended meaning.

A more useful plural example is:

• Její bratři jsou veterináři. = Her brothers are veterinarians.

The main changes are:

• je → jsou = are
• veterinář → veterináři = veterinarians

Yes: Czech stress is usually on the first syllable of each word.

So:

• JE-jí
• MUŽ
• JE
• VE-te-ri-nář

Even though á is a long vowel in veterinář, the stress still stays at the beginning of the word, not on the long vowel.

That is different from English, where stress often moves around unpredictably.
