Ako te čelo i dalje boli, stavi hladan ručnik na njega i odmaraj se.

In Croatian, boljeti often works a bit differently from English.

• čelo boli = the forehead hurts
• te čelo boli = literally the forehead hurts you, meaning your forehead hurts

So te is the unstressed pronoun meaning you in this structure. It shows who is affected by the pain.

This pattern is very common:

• Boli me glava. = My head hurts.
• Bole ga leđa. = His back hurts.
• Boli nas grlo. = Our throat hurts.

You can say tvoje čelo, but that would emphasize your forehead as a thing, and it is less natural in this everyday medical/advice sentence.

Te is the accusative clitic form of ti (you, singular, informal).

In this sentence:

• te = you
• čelo = forehead
• boli = hurts

So:

• Ako te čelo boli... = If your forehead hurts...

Even though English uses your, Croatian often uses a pronoun like me, te, ga, je, nas with body parts and sensations.

Examples:

• Boli me ruka. = My arm hurts.
• Boli te zub. = Your tooth hurts.
• Bole je oči. = Her eyes hurt.

Because the grammatical subject is čelo (forehead), and čelo is singular.

So the structure is:

• čelo boli = the forehead hurts

If the subject were plural, the verb would also be plural:

• Oči te bole. = Your eyes hurt.
• Leđa me bole. = My back hurts.
  (Literally back is treated as plural in Croatian: leđa.)

So boli agrees with čelo, not with te.

I dalje means still, continuing, or anyway still depending on context.

Here:

• Ako te čelo i dalje boli... = If your forehead still hurts...

It suggests that the pain has not stopped.

Some similar examples:

• Još sam umoran. = I am still tired.
• I dalje sam umoran. = I am still tired / I continue to be tired.

In many situations, još and i dalje can both be translated as still, but i dalje often emphasizes continuation a bit more.

Stavi is the imperative of staviti, meaning put, place, or apply.

So:

• stavi hladan ručnik = put a cold towel

This is a command or piece of advice addressed to one person informally.

Related forms:

• stavi! = put! (to one person, informal)
• stavite! = put! (to more than one person, or polite singular)

So the sentence is speaking to one person in an informal way.

Because ručnik (towel) is masculine singular, and after stavi we need the direct object in the accusative.

For masculine inanimate nouns, the accusative singular is usually the same as the nominative singular.

So:

• nominative: hladan ručnik
• accusative: hladan ručnik

That is why it looks unchanged.

Agreement:

• hladan matches ručnik
• both are masculine singular accusative

Compare with feminine:

• stavi hladnu krpu = put a cold cloth

There the adjective changes more visibly.

Njega refers to čelo (forehead).

So:

• na njega = onto it / on it
• here: on your forehead

Even though čelo is a neuter noun, the pronoun after na in this context is njega.

So the full part means:

• stavi hladan ručnik na njega = put a cold towel on it

meaning put a cold towel on your forehead.

Croatian often uses a pronoun to refer back to a noun instead of repeating the noun itself.

You could also repeat the noun:

• stavi hladan ručnik na čelo

That is also natural.

Because na can take different cases depending on the meaning.

• na + accusative = motion toward / putting something onto a surface
• na + locative = location on a surface

Here the verb is stavi (put/place), so there is movement or placement onto the forehead. That is why we use accusative:

• na njega

Compare:

• Stavi ručnik na stol. = Put the towel on the table.
• Ručnik je na stolu. = The towel is on the table.

So:

• stavi ... na njega = put ... onto it
• if you were describing location afterward, you would use a locative form instead

Yes, absolutely.

Both are possible:

• stavi hladan ručnik na njega
• stavi hladan ručnik na čelo

The second version may feel a bit more direct and perhaps simpler for a learner. The version with na njega avoids repeating čelo.

So the choice is mostly stylistic here.

Because the verb is odmarati se, which means to rest.

The se is part of the verb. In English we do not say rest yourself in the same way, but in Croatian this is normal.

So:

• odmarati se = to rest
• odmaraj se = rest / keep resting

Without se, the meaning changes or sounds incomplete in this context.

This is about aspect, which is very important in Croatian.

• odmarati se = imperfective
• odmoriti se = perfective

Imperatives:

• odmaraj se = rest, keep resting, spend time resting
• odmori se = have a rest, rest up

In advice like this, odmaraj se suggests an ongoing action or repeated advice: rest, take it easy, keep resting.

Meanwhile:

• odmori se can sound a bit more like go get some rest as one complete action.

Both can be natural, but odmaraj se emphasizes the process.

Because te is a clitic, and Croatian clitics usually appear in the second position in their clause.

So in:

• Ako te čelo i dalje boli...

the conjunction Ako starts the clause, and the clitic te comes immediately after it.

This kind of placement is very typical in Croatian:

• Ako te vidim, javit ću ti. = If I see you, I’ll let you know.
• Kad mi kažeš, razumjet ću. = When you tell me, I’ll understand.

For learners, the easiest rule is: short pronouns like me, te, ga, je, se often come very early in the clause.

Yes. Ako is the standard word for if in conditional sentences.

Examples:

• Ako pada kiša, ostajem doma. = If it rains, I’m staying home.
• Ako te boli glava, odmori se. = If your head hurts, rest.

So here:

• Ako te čelo i dalje boli... = If your forehead still hurts...

Because the sentence begins with a subordinate clause introduced by Ako.

Structure:

• Ako te čelo i dalje boli, = subordinate if clause
• stavi hladan ručnik na njega i odmaraj se. = main clause

Croatian normally uses a comma to separate that introductory conditional clause from the main clause.

This is similar to English:

• If your forehead still hurts, put a cold towel on it and rest.

It is informal singular.

You can tell because of the imperative forms:

• stavi
• odmaraj se

These are used when speaking to:

• one person
• informally
• someone you would address as ti

A polite or plural version would be:

• Ako vas čelo i dalje boli, stavite hladan ručnik na njega i odmarajte se.

Though in real life, a doctor might choose slightly different wording to sound more natural or professional.

Yes. Čelo has more than one meaning depending on context.

Common meanings include:

• forehead
• front
• head/front position in some expressions

In this sentence, because of boli and the health context, it clearly means forehead.

Examples:

• Boli me čelo. = My forehead hurts.
• na čelu kolone = at the head/front of the column

So context tells you which meaning is intended.

Yes, and that would also be natural.

Both word orders are possible:

• Ako te čelo boli
• Ako te boli čelo

Croatian word order is more flexible than English. The difference is usually about focus or rhythm, not basic meaning.

A learner should understand both as:

• If your forehead hurts

The version in your sentence is perfectly normal.

Here are the main forms:

• ako = if
• te = you (accusative clitic, from ti)
• čelo = forehead
• i dalje = still, continuing
• boljeti = to hurt, ache
• stavi = put, place, apply (imperative of staviti)
• hladan = cold
• ručnik = towel
• na = on, onto
• njega = him/it (accusative form used here to mean it)
• odmaraj se = rest (imperative of odmarati se)

Knowing the dictionary forms helps you recognize related forms in other sentences.

Yes, it is natural and understandable.

It sounds like practical advice:

• If your forehead still hurts, put a cold towel on it and rest.

A native speaker might also say something like:

• Ako te i dalje boli čelo, stavi hladan ručnik na čelo i odmaraj se.
• Ako te čelo još boli, stavi hladan ručnik na njega i odmori se.

These are small variations in word order, vocabulary, or aspect, but the original sentence is perfectly good Croatian.
