Ako te boli grlo, nemoj piti hladnu vodu odmah poslije trčanja.

Ako means if.

This sentence is a conditional sentence:

• Ako te boli grlo = If your throat hurts
• nemoj piti hladnu vodu... = don’t drink cold water...

In Croatian, this kind of everyday advice often uses the present tense in the if clause.

Because the verb boljeti works differently from English to hurt.

In Croatian, the person who feels the pain is usually in the accusative, not the nominative. So:

• te = you in the short accusative form
• ti would be dative, so it is not the normal form here

So te boli grlo literally works like the throat hurts you, even though in natural English we say your throat hurts or you have a sore throat.

Yes.

Grammatically, grlo is the subject, and it is in the nominative singular. The verb boli agrees with it.

So the structure is:

• grlo = subject
• boli = hurts
• te = the person affected

A useful comparison:

• Boli me glava. = My head hurts.
• Bole me oči. = My eyes hurt.

Notice how the verb changes:

• singular thing hurting: boli
• plural things hurting: bole

Because Croatian often does not need a possessive adjective when the meaning is already clear from the pronoun.

Here, te already tells us who is affected, so grlo is naturally understood as your throat.

So Croatian prefers:

• Ako te boli grlo...

rather than:

• Ako te boli tvoje grlo...

The version with tvoje is possible only if you really want to emphasize your throat, but in normal speech it sounds unnecessary.

This is the normal way to make a negative command in Croatian for you singular informal.

The pattern is:

• nemoj + infinitive

So:

• nemoj piti = don’t drink

This is much more common and natural than trying to negate the positive imperative directly.

For comparison:

• positive command: Pij vodu. = Drink water.
• negative command: Nemoj piti vodu. = Don’t drink water.

You may hear ne pij, and people will understand it, but standard Croatian usually prefers nemoj + infinitive for negative commands.

So in most learning contexts, nemoj piti is the safer and more natural choice.

A rough difference is:

• nemoj piti = standard, neutral, normal
• ne pij = possible, but can sound more abrupt or less standard depending on context

This is a question of aspect, which is very important in Croatian.

• piti = imperfective, focusing on the action in general
• popiti = perfective, focusing on a completed act of drinking

In this sentence, nemoj piti hladnu vodu means don’t drink cold water in that situation. It sounds like general advice.

If you said nemoj popiti hladnu vodu, it would sound more like:

• don’t go and drink that cold water
• don’t have a cold drink as a completed act

So piti is the more natural choice for general advice here.

Because voda is the direct object of piti, and direct objects after this verb are in the accusative.

Base form:

• hladna voda = cold water nominative

In this sentence:

• hladnu vodu = accusative singular

The adjective and noun both change because they must agree:

• hladna → hladnu
• voda → vodu

So:

• piti hladnu vodu = to drink cold water

Word by word:

• odmah = immediately / right away
• poslije = after
• trčanja = running

So odmah poslije trčanja means immediately after running or right after running.

Trčanja is the genitive singular form of trčanje, which is a verbal noun meaning running.

This is very common in Croatian:

• verb: trčati = to run
• verbal noun: trčanje = running

After the preposition poslije, Croatian uses the genitive, so:

• poslije trčanja = after running

This is similar to how English uses an -ing form, but Croatian usually handles it through a noun form and case ending.

Yes. Both are correct.

• poslije trčanja
• nakon trčanja

Both mean after running.

In many contexts they are interchangeable. In this sentence, odmah poslije trčanja and odmah nakon trčanja both sound natural.

Because te is a clitic. Croatian clitics usually appear near the beginning of the clause, often in the second position.

So:

• Ako te boli grlo... is normal

The clitic te comes very early, right after ako.

This early placement is a normal feature of Croatian word order. Even though Croatian word order is fairly flexible, clitics like te, me, ga, je, se have special placement rules.

Then you would use vas and nemojte:

• Ako vas boli grlo, nemojte piti hladnu vodu odmah poslije trčanja.

So the changes are:

• te → vas
• nemoj → nemojte

This is used for:

• plural you
• polite/formal singular you
