Nos mi opet curi, pa ću nazvati doktoricu ako sutra ne bude bolje.

Here mi means to me.

Croatian often uses a dative pronoun where English would use a possessive idea:

• Nos mi curi. = literally The nose is running to me
• natural English: My nose is running

So mi is a short form of meni and shows whose nose it is, without needing moj.

This kind of structure is very common in Croatian:

• Boli me glava. = My head hurts
• Ruka mi je hladna. = My hand is cold
• Auto mi ne radi. = My car isn’t working

It can, but it usually sounds less natural in this kind of everyday statement.

Croatian often prefers the pattern:

• Nos mi curi instead of
• Moj nos curi

Using moj is more emphatic, as if you are contrasting it with someone else’s nose or drawing attention to the fact that it is my nose.

So:

• Nos mi curi = normal, everyday
• Moj nos curi = possible, but more marked or emphatic

Yes, Croatian word order is flexible, and several versions are possible.

The sentence Nos mi opet curi is natural, but so are:

• Opet mi curi nos.
• Nos mi opet curi.
• Opet mi nos curi.

The differences are mostly about focus and rhythm, not core meaning.

A few things matter:

1. mi is a clitic, so it usually goes near the beginning of the clause, in second position.
2. Croatian often moves words around to highlight what is most important.
3. In speech, the version with opet early can sound especially natural:
   • Opet mi curi nos.

So the sentence you have is fine, but it is not the only possible order.

Curi is from the verb curiti, meaning to flow, to drip, or to leak.

So Nos mi curi is literally something like:

• My nose is dripping / leaking

In natural English, we usually say:

• My nose is running

Croatian uses the same verb curiti in other situations too:

• Voda curi iz slavine. = Water is leaking/dripping from the tap.
• Krov curi. = The roof leaks.

So the image is very physical: something is flowing out.

Pa is a very common connector in Croatian. Here it means something like:

• so
• then
• in that case

In this sentence, it links the first situation to the consequence:

• Nos mi opet curi, pa ću nazvati doktoricu...
• My nose is running again, so I’ll call the doctor...

It is not exactly the same as i (and). It suggests a result or next step.

You will hear pa constantly in everyday Croatian, often with slightly different shades depending on context.

Croatian forms the future tense with:

• the auxiliary htjeti in its short form
• plus the infinitive

So:

• ću nazvati = I will call

The short future forms are:

• ću = I will
• ćeš = you will
• će = he/she/it will
• ćemo = we will
• ćete = you will
• će = they will

Examples:

• Nazvat ću doktoricu.
• Ja ću nazvati doktoricu.

Both mean I will call the doctor.

Croatian allows different placements depending on word order and whether the infinitive comes before or after the clitic.

This is mainly about aspect.

• zvati = imperfective, more like to call / be calling
• nazvati = perfective, more like to call once / make the call

In this sentence, the speaker means a single completed action in the future:

• I’ll call the doctor

That is why nazvati is the natural choice.

Compare:

• Zvat ću je cijeli dan. = I’ll be calling her all day.
  (repeated/ongoing idea)
• Nazvat ću je sutra. = I’ll call her tomorrow.
  (one complete action)

Because doktoricu is the accusative singular form.

The verb nazvati takes a direct object, and direct objects go in the accusative:

• nazvati doktoricu = to call the female doctor

Here are the forms:

• nominative: doktorica = female doctor
• accusative: doktoricu

This is a normal feminine noun pattern:

• učiteljica → učiteljicu
• prijateljica → prijateljicu

Yes. Doktorica is specifically a woman doctor.

If the doctor were male, you would say:

• doktor in nominative
• doktora in accusative

So:

• Nazvat ću doktoricu. = I’ll call the female doctor.
• Nazvat ću doktora. = I’ll call the male doctor.

In modern Croatian, liječnica / liječnik are also very common and sometimes feel a bit more formal or standard than doktorica / doktor.

This is a very important point.

After words like ako (if), Croatian normally does not use the ordinary future with će the way English does with will.

Instead, it often uses the present form of a verb that can refer to the future. Here that form is:

• bude from biti

So:

• ako sutra ne bude bolje = if it isn’t better tomorrow / if it doesn’t get better by tomorrow

Using ako sutra neće biti bolje is generally not the normal choice here.

This is similar to how English also often avoids will after if:

• English: If it is not better tomorrow, I’ll call...
• not usually: If it will not be better tomorrow, I’ll call...

So Croatian and English are actually fairly similar here.

Bude is a form of biti (to be), but in this context it is used in a clause referring to the future.

After ako, kad, and some similar conjunctions, Croatian often uses this kind of present-form verb to talk about a future condition or event:

• ako bude vremena = if there is time / if there will be time
• kad dođe = when he comes
• ako ne bude bolje = if it doesn’t get better

So even though bude looks like a present-tense form, here it points to a future situation.

Bolje is the comparative form of dobro (well) or the neuter comparative form corresponding to bolji (better).

In expressions like:

• biti bolje
• osjećati se bolje

Croatian uses bolje, not bolji, because the idea is not a better person/object, but rather a better state/condition.

So:

• Ne bude bolje = It won’t be better / It doesn’t get better

Compare:

• On je bolji liječnik. = He is a better doctor.
  Here bolji agrees with a masculine noun.
• Danas mi je bolje. = I feel better today.
  Here bolje refers to the overall condition/state.

Yes, absolutely.

• ...ako sutra ne bude bolje
• ...ako mi sutra ne bude bolje

Both are natural.

Adding mi makes it more explicit that the condition is better for me / my state:

• ako mi sutra ne bude bolje = if I’m not better tomorrow

Without mi, the meaning is still clear from context, especially because the sentence is already about the speaker’s symptoms.

Yes, very natural.

It sounds like normal spoken Croatian: simple, conversational, and idiomatic.

A speaker might also say similar versions such as:

• Opet mi curi nos, pa ću nazvati doktoricu ako sutra ne bude bolje.
• Nos mi opet curi, pa ću sutra nazvati doktoricu ako ne bude bolje.

The exact word order may vary, but the grammar and phrasing are everyday Croatian.
