Learn Croatian: Pita me je li salon otvoren. - She asks me if the salon is open.

In Croatian, ako is strictly used for conditional statements, like 'If it rains, we will stay home.' When 'if' means 'whether' in a reported question, you must use je li.

Why is the pronoun me (accusative) instead of mi (dative)? Don't you ask a question 'to' someone?

While we often think of directing a question 'to' someone, the Croatian verb pitati (to ask) takes a direct object. This means it requires the accusative case for the person being asked. Therefore, you must use the accusative me, not the dative mi.

Does je li always have to come right after the main clause?

Yes, in a reported question, je li acts as the conjunction (meaning 'whether'). It introduces the reported clause and must come immediately before it, right after the main verb phrase Pita me.

Why is it otvoren and not otvoreni?

Otvoren is the indefinite form of the adjective. When an adjective is used after a verb to state a fact about the subject, rather than sitting directly next to a noun as a modifier, Croatian prefers this shorter indefinite form.
