Moje kamarádka Eva je studentka.

Because moje has to agree with kamarádka, which is a feminine singular noun.

In Czech, possessive words like my change form depending on the noun they go with:

• můj kamarád = my male friend
• moje kamarádka = my female friend
• moje auto = my car

So in this sentence, moje matches the feminine noun kamarádka.

Kamarádka means female friend.

It is the feminine form of kamarád:

• kamarád = male friend
• kamarádka = female friend

A native English speaker may notice that English usually just says friend, while Czech often makes the gender clear.

Also, kamarádka normally means a friend in the general, non-romantic sense.

Here, Eva identifies which friend you mean: my friend Eva.

So kamarádka Eva works like an apposition, similar to English expressions such as:

• my friend Eva
• Professor Novák
• my sister Anna

In Czech, this is very natural. The sentence could also be rearranged, for example:

• Eva je moje kamarádka. = Eva is my friend.

That version changes the emphasis a little, but the basic meaning stays very similar.

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

So:

• je = is

In this sentence:

• Eva je studentka = Eva is a student

Unlike in some other languages, Czech normally keeps this verb in ordinary present-tense sentences. So you usually do need je here.

Because Eva is female, and Czech nouns for people often show gender.

• student = male student
• studentka = female student

So if the subject is Eva, the natural form is studentka.

This is very common in Czech:

• učitel / učitelka = teacher
• Američan / Američanka = American
• kamarád / kamarádka = friend

Correct: Czech has no articles like English a, an, or the.

So studentka can mean:

• a student
• the student

The exact meaning depends on context.

That is why Eva je studentka naturally translates as Eva is a student, even though there is no separate word for a.

They are in the nominative, because they are used as the subject or as a predicate noun after to be.

In this sentence:

• kamarádka is nominative singular
• Eva is nominative singular
• studentka is nominative singular

A useful point for learners: after je in a simple sentence like this, Czech commonly uses the nominative:

• Eva je studentka.
• Petr je učitel.

So this is a good basic pattern to remember.

Yes. Czech word order is more flexible than English word order.

This sentence can appear in different orders depending on emphasis:

• Moje kamarádka Eva je studentka.
• Eva je moje kamarádka.
• Studentka je moje kamarádka Eva. — possible, but much less neutral

The original sentence sounds natural if you are introducing Eva by first saying who she is to you, and then saying something about her.

English relies more heavily on fixed word order, but Czech often uses word order to show what is already known and what is new information.

A rough pronunciation guide for an English speaker is:

• moje ≈ MO-ye
• kamarádka ≈ ka-ma-RAAT-ka
• Eva ≈ EH-va
• je ≈ ye
• studentka ≈ STOO-dent-ka

A few helpful notes:

• j in Czech is pronounced like English y in yes
• á is a long vowel
• stress is usually on the first syllable of each word

So the sentence sounds roughly like:

MO-ye ka-ma-RAAT-ka EH-va ye STOO-dent-ka

Because -ka is a very common feminine ending in Czech, especially for nouns referring to women.

For example:

• kamarád → kamarádka
• student → studentka
• učitel → učitelka

It is not the only feminine ending in Czech, but it is a very frequent one. For a learner, it is useful because it often helps you guess that the noun refers to a female person.

Yes, you may hear that, but for a beginner the safest version is studentka.

After forms of být (to be), Czech often uses the nominative in simple identification sentences:

• Eva je studentka.

In some contexts, speakers also use the instrumental:

• Eva je studentkou.

Both can occur, but the nominative version is especially common and straightforward in basic sentences like this one. If you are just learning, Eva je studentka is an excellent model to follow.

It is one person: Eva.

The phrase means my friend Eva, not my friend and Eva.

So the structure is:

• moje kamarádka = my friend
• Eva = the name of that friend

Together, moje kamarádka Eva refers to a single female person named Eva.
