Juha je prevruća, pa je još ne možemo kušati.

Because prevruća has to agree with juha.

In Croatian, adjectives agree with the noun in gender, number, and case.

• juha is feminine
• singular
• nominative here, because it is the subject

So the adjective also takes the feminine singular nominative form: prevruća.

Compare:

• prevruć čaj = too hot tea
• prevruća juha = too hot soup
• prevruće mlijeko = too hot milk

Here pre- means too, excessively.

So:

• vruća = hot
• prevruća = too hot

That is different from simply saying very hot.

• vrlo vruća = very hot
• prevruća = so hot that it is a problem

So in this sentence, prevruća implies too hot to taste right now.

That je is the present-tense form of biti = to be.

So the first clause is built like this:

• Juha = soup
• je = is
• prevruća = too hot

Together: The soup is too hot.

Croatian normally uses je here, just like English uses is.

They are two different words that just happen to look the same.

1. In Juha je prevruća, je = is
   This is the verb biti.

2. In pa je još ne možemo kušati, je = it
   This is a short unstressed pronoun referring back to juha.

So:

• first je = is
• second je = it

Croatian often has these short forms that look identical, and the meaning is understood from the sentence structure.

Because Croatian has two common short feminine singular object forms here: je and ju.

So both of these can be heard:

• pa je još ne možemo kušati
• pa ju još ne možemo kušati

Both refer back to juha, which is feminine.

Learners should mainly know this:

• je/ju here = it/her
• it agrees with the feminine noun juha

Because Croatian short pronouns like je usually appear very early in the clause.

That short je is a clitic: an unstressed little word that does not usually stand in a strong, independent position. Croatian tends to place such words near the beginning of the clause.

So after pa, it is natural to get:

• pa je ...

Then:

• još = still / yet
• ne možemo = we cannot
• kušati = taste

Also notice that ne goes directly before the finite verb možemo.

A fuller version without the short pronoun would be something like:

• pa juhu još ne možemo kušati
• pa nju još ne možemo kušati

Here još means still or yet.

So:

• još ne možemo = we still cannot / we cannot yet

This is a very common use of još in negative sentences.

It does not mean more in this sentence.

Because moći + infinitive expresses ability or possibility.

• možemo kušati = we can taste
• ne možemo kušati = we cannot taste

If you said ne kušamo, that would mean something more like:

• we are not tasting
• we do not taste

That is a different idea. The Croatian sentence is about not being able to taste the soup because it is too hot.

Kušati means to taste, especially food or drink.

In this sentence it means taking a taste of the soup, not necessarily eating the whole thing.

A learner should compare:

• kušati = taste, sample
• probati = try, test; often also used for taste
• jesti = eat

So kušati is a very suitable verb here because the sentence is about whether the soup is cool enough to taste.

Here pa means something like so, and so, or therefore.

It connects the first clause to the result:

• Juha je prevruća = the soup is too hot
• pa je još ne možemo kušati = so we still cannot taste it

It is a very natural Croatian connector in everyday speech.

It is not the same as:

• jer = because

So this sentence is giving a result, not introducing a reason with because.
