Ako bol ne prođe do sutra, ići ću na pregled i možda dobiti tablete.

After ako (if), Croatian usually does not use the future tense to talk about a future condition. It normally uses the present tense instead.

So:

• Ako bol ne prođe... = If the pain doesn't go away...

This is actually very similar to English, where we also say:

• If the pain doesn't go away, I'll... not
• If the pain won't go away, I'll... in the normal neutral sense.

Also, prođe comes from the perfective verb proći, which is important here because the idea is whether the pain will have gone away by a certain point.

Croatian aspect matters a lot here.

• proći = perfective, focusing on a completed result: to pass / to go away
• prolaziti = imperfective, focusing on an ongoing process or repeated action

So:

• Ako bol ne prođe do sutra = If the pain hasn't gone away by tomorrow
• Ako bol ne prolazi = If the pain isn't going away / isn't subsiding

In this sentence, the speaker is thinking about a deadline/result by tomorrow, so prođe is the natural choice.

In this sentence, do sutra means by tomorrow.

Literally, do often means until, but with time limits it often corresponds to English by:

• do sutra = by tomorrow
• do petka = by Friday
• do večeras = by this evening

So here the meaning is: if the pain has not passed by tomorrow.

Because Croatian has no articles.

There is no separate word for a / an / the. Croatian usually leaves that idea to context.

So:

• bol can mean pain, the pain, or sometimes a pain, depending on context.

In this sentence, English would naturally say the pain, but Croatian simply says bol.

Both patterns exist in Croatian future tense, but clitic words like ću cannot stand in first position in a clause.

Here the main clause begins after the comma, and it starts directly with the verb. So Croatian uses:

• ići ću

This is a normal way to form the future.

Compare:

• Ići ću na pregled. = I will go for an examination.
• Ja ću ići na pregled. = also correct, because now ću is in second position, after ja

So ići ću is used because ću cannot just stand at the beginning by itself.

Because one future auxiliary can apply to more than one infinitive when the verbs are coordinated.

So:

• ići ću na pregled i možda dobiti tablete

means roughly:

• I will go for an examination and maybe get tablets

The ću is understood with both ići and dobiti.

You could also say:

• ići ću na pregled i možda ću dobiti tablete

but the original version is more compact and very natural.

Because ići na pregled is the normal Croatian expression for to go for an examination / check-up.

Here na + accusative is used for going to certain events, appointments, procedures, or activities.

Examples:

• ići na posao = to go to work
• ići na operaciju = to go for surgery
• ići na pregled = to go for an examination/check-up

So this is something you should learn as a common phrase.

Tablete is in the accusative plural, because it is the direct object of dobiti (to get / receive).

• dobiti što? = to get what?
• tablete

The dictionary form is tableta.

For many feminine nouns in -a, the plural forms look like this:

• nominative plural: tablete
• accusative plural: tablete

So here the form is accusative, even though it looks the same as nominative plural.

Because Croatian often drops subject pronouns when the verb already makes the subject clear.

In:

• ići ću

the form ću already tells you it is first person singular: I will.

So Croatian usually does not say ja unless there is emphasis or contrast.

• Ići ću na pregled. = normal
• Ja ću ići na pregled. = more emphatic, like I will go...

Because the sentence begins with a subordinate if-clause:

• Ako bol ne prođe do sutra, ...

When that dependent clause comes first, Croatian normally separates it from the main clause with a comma.

So the structure is:

• Ako bol ne prođe do sutra, = subordinate clause
• ići ću na pregled i možda dobiti tablete. = main clause

This is very similar to English punctuation:

• If the pain doesn't go away by tomorrow, I'll...

In this sentence, možda most naturally goes with dobiti tablete:

• i možda dobiti tablete = and maybe get tablets

So the idea is:

• going for the examination is presented as the likely plan
• getting tablets is presented as possible, but not certain

Croatian word order is flexible, so moving možda can slightly shift the emphasis, but here its most natural reading is with dobiti tablete.

Two sounds here are often tricky for English speakers:

• đ in prođe
• ć in ću

A simple approximation:

• đ sounds somewhat like a soft English j
• ć sounds like a very soft ch/t

So:

• prođe is roughly like PRO-jyeh (approximation only)
• ću is roughly like tyoo or a very soft chyoo, depending on your accent

The exact Croatian sounds are softer and more precise than English ones, but those approximations can help at first.
