Moram zakazati pregled kod doktorice za petak.

Because Croatian usually does not need a subject pronoun when the verb already shows who is doing the action.

• Moram = I must / I need to
• The ending -am already tells you the subject is I

So:

• Moram zakazati pregled... = I need to schedule an appointment...
• Ja moram zakazati pregled... is also possible, but ja is usually added only for emphasis, contrast, or clarity.

For example:

• Moram = neutral, normal
• Ja moram = I have to, maybe not someone else

Moram comes from the verb morati, meaning must / have to / need to.

In English, the best translation depends on context:

• must
• have to
• need to

In this sentence, need to or have to sounds most natural in English:

• Moram zakazati pregled... = I need to schedule an appointment...
• or I have to schedule an appointment...

So moram expresses necessity or obligation.

Zakazati means to schedule, to arrange, or to set up something for a specific time.

Here it is used for making an appointment:

• zakazati pregled = to schedule an examination / appointment

A very important point: zakazati is a perfective verb. That means it refers to a completed, single action.

So:

• Moram zakazati pregled = I need to schedule an appointment
  → one concrete act of arranging it

If you used an imperfective form instead, it would suggest repeated or ongoing action, which would not fit as well here.

Yes. Pregled literally means examination, check-up, or sometimes appointment, depending on context.

In a medical context:

• pregled = a medical examination / check-up
• In natural English, people often translate the whole phrase as appointment, even though the Croatian word is literally closer to examination

So:

• zakazati pregled literally = to schedule an examination
• natural English = to make / schedule an appointment

Grammatically, pregled is in the accusative singular, but for this masculine inanimate noun, the accusative looks the same as the nominative:

• nominative: pregled
• accusative: pregled

It is accusative because it is the direct object of zakazati.

In this sentence, kod means something like:

• with
• at the office/practice of
• to see

So:

• pregled kod doktorice = an appointment/check-up with the doctor
• more literally: an examination at the female doctor’s place / with the female doctor

Croatian often uses kod + genitive when talking about going to or being with a person, especially for services:

• kod doktora = at the doctor’s / with the doctor
• kod frizera = at the hairdresser’s
• kod zubara = at the dentist’s

So kod is a very common and natural choice here.

Because kod requires the genitive case, and doktorice is the genitive singular form of doktorica.

Forms:

• nominative: doktorica = female doctor
• genitive: doktorice

So:

• doktorica = the doctor
• kod doktorice = with / at the female doctor

This also tells you the doctor is female.
If the doctor were male, you would say:

• kod doktora

Both are possible, but they are slightly different in style.

• doktorica = doctor
• liječnica = physician / doctor

In everyday speech, many people commonly say doktorica.
Liječnica can sound a bit more formal or standard in some contexts.

So these are both possible:

• Moram zakazati pregled kod doktorice za petak.
• Moram zakazati pregled kod liječnice za petak.

Both are correct. The first often sounds a little more conversational.

Za petak means for Friday.

When scheduling something, Croatian often uses:

• za + accusative

to mean that something is arranged for a certain time/day.

So:

• zakazati pregled za petak = schedule an appointment for Friday

Here, petak is in the accusative singular, and for this noun it looks the same as the nominative:

• nominative: petak
• accusative: petak

Why not u petak?

• u petak usually means on Friday
• za petak means for Friday, especially in the sense of scheduling or planning something

Compare:

• Pregled je u petak. = The appointment is on Friday.
• Zakazao sam pregled za petak. = I scheduled the appointment for Friday.

So za petak is the natural choice here because the sentence is about arranging the appointment.

Croatian word order is fairly flexible, but some orders sound more natural than others.

The neutral order here is:

• Moram zakazati pregled kod doktorice za petak.

You can move parts around for emphasis, for example:

• Moram za petak zakazati pregled kod doktorice.
• Pregled kod doktorice moram zakazati za petak.

These are grammatically possible, but they sound more marked or emphasize different parts of the sentence.

For learners, it is best to keep the neutral order until you become comfortable with emphasis patterns.

Yes, that is a very useful thing to know. In medical contexts, Croatian speakers often use:

• naručiti pregled
• naručiti se kod doktorice
• dogovoriti pregled

depending on region and style.

For example:

• Moram se naručiti kod doktorice za petak.
• Moram naručiti pregled za petak.

These can sound very natural too.
Still, zakazati pregled is understandable and correct in many contexts, especially if you mean schedule in a straightforward way.

You would change the gender form after kod and the day after za.

For a male doctor:

• Moram zakazati pregled kod doktora za petak.

For a female doctor:

• Moram zakazati pregled kod doktorice za petak.

Different days:

• za ponedjeljak = for Monday
• za utorak = for Tuesday
• za srijedu = for Wednesday
• za četvrtak = for Thursday
• za subotu = for Saturday

Example:

• Moram zakazati pregled kod doktora za ponedjeljak.

So the structure stays the same:

• Moram + infinitive + object + kod + person in genitive + za + day/time

A simple pronunciation guide is:

Moram zakazati pregled kod doktorice za petak.
MO-ram za-ka-ZA-ti PRE-gled kod dok-to-RI-tse za PE-tak

A few helpful notes:

• r in Croatian is rolled or tapped
• lj, nj, č, ć, ž, š have distinct sounds, but none of those tricky pairs are the main issue here
• c in doktorice is pronounced like ts
• stress in Croatian is not always marked in writing, so learners usually pick it up gradually by listening

If your goal is just to be understood, a clear pronunciation of each syllable matters more than perfect stress.
