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

Why is it te čelo boli and not something like tvoje čelo boli?

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:

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.

What exactly is te here?

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

In this sentence:

So:

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