Razrednica mi je jutros poslala poruku i pitala kako je moja kći.

Razrednica is a female homeroom teacher / class teacher.

Croatian often marks the teacher’s gender in the noun:

• razrednik = a male homeroom teacher
• razrednica = a female homeroom teacher

It is feminine here because the person being talked about is a woman. That also affects the past-tense verbs later in the sentence: poslala and pitala are feminine forms.

Mi here means to me.

It is the unstressed dative form of ja:

• ja = I
• meni / mi = to me

So:

• Razrednica mi je poslala poruku = The homeroom teacher sent me a message

English usually says sent me, while Croatian often uses this short clitic pronoun mi.

Both mi and je are clitics, meaning short unstressed words that usually come near the beginning of the clause.

Here:

• mi = to me
• je = is/has, the auxiliary used to form the past tense

So mi je poslala means has sent to me / simply sent me.

Croatian clitics have a fairly fixed position, so mi je sounds natural, while something like je mi in this sentence would normally not be used in the same way.

They are in the past tense, and they agree with the subject razrednica, which is feminine singular.

Croatian past tense is formed with:

• a present-tense form of biti (je here)
• a past participle-like form that agrees with the subject

So:

• poslala = sent, feminine singular
• pitala = asked, feminine singular

Compare:

• razrednica je poslala = the female teacher sent
• razrednik je poslao = the male teacher sent

Poruku is accusative singular.

The basic dictionary form is:

• poruka = message

But because it is the direct object of poslala (sent), Croatian uses the accusative:

• poslala poruku = sent a message

So:

• nominative: poruka
• accusative: poruku

This is very common with feminine nouns ending in -a:

• knjiga → knjigu
• škola → školu
• poruka → poruku

Jutros means this morning or earlier this morning.

It is an adverb, not a noun in a case form.

Compare:

• jutro = morning
• jutros = this morning

So:

• jutros je poslala poruku = she sent a message this morning

English learners sometimes expect a preposition here, but Croatian does not need one.

Croatian often leaves out subject pronouns when they are already clear from context or verb form.

In this sentence, the subject is already stated as razrednica, so there is no need to add ona (she).

Croatian does this much more than English:

• Razrednica je poslala poruku.
• literally: The homeroom teacher sent a message.
• no extra she is needed

This means asked how my daughter is.

The part kako je moja kći is an embedded clause:

• kako = how
• je = is
• moja kći = my daughter

Inside that clause:

• moja kći is the subject, so it is in the nominative
• je is the verb is

So literally it is:

• asked how my daughter is

This follows the same word order you would expect in a normal statement:

• Moja kći je dobro. / Moja kći je umorna.
• Kako je moja kći? = How is my daughter?
• embedded: pitala kako je moja kći

Yes, kći is somewhat irregular and is worth learning separately.

It means daughter, and its nominative singular is:

• kći

This noun does not behave like a typical -a feminine noun such as žena.

You will often meet other forms like:

• kćeri = of/to daughter, daughters, depending on context

So for a learner, the important thing is:

• moja kći = my daughter

Even if you do not know the full declension yet, it is good to recognize that kći is a common but slightly unusual noun.

Kći is one of the trickier Croatian words for English speakers.

A rough guide is:

• k
  • a soft ć sound + i

The ć is softer than English ch.
It is not exactly English, but a rough approximation might be something like ktyee, said quickly and softly.

Important points:

• ć is softer than č
• the final i is clearly pronounced

If you cannot say it perfectly at first, that is normal. It is a difficult cluster even for many learners who know other Slavic languages.

Yes, Croatian word order is flexible, but not completely free.

For example, you could also say:

• Jutros mi je razrednica poslala poruku i pitala kako je moja kći.

This still means the same thing, but the emphasis shifts slightly to this morning.

What usually stays important is the placement of the clitics:

• mi
• je

They normally stay near the beginning of the clause, so some word orders sound natural and others do not.

Moja agrees with kći.

Since kći is:

• feminine
• singular
• nominative

the possessive adjective must match it:

• moj = my, masculine
• moja = my, feminine
• moje = my, neuter

So:

• moj sin = my son
• moja kći = my daughter
• moje dijete = my child

This agreement is a basic feature of Croatian adjectives and possessives.

Because both verbs share the same subject and the same auxiliary.

The full structure would be something like:

• Razrednica mi je poslala poruku i (je) pitala kako je moja kći.

But repeating the second je is unnecessary, so Croatian normally omits it.

This is similar to English:

• She sent me a message and asked... You do not repeat she before asked unless you want special emphasis.

So Croatian naturally says:

• mi je poslala poruku i pitala...
