Questions & Answers about Sve sada ovisi o tebi.
Why do we use the full pronoun tebi here instead of the short form ti?
Because it comes after a preposition. In Croatian, whenever a personal pronoun follows a preposition (like o), you must use its full, emphatic form. The short form ti cannot be used after a preposition.
Does the preposition o usually mean "on"?
Generally, o means "about" (as in talking about something). However, the verb ovisiti (to depend) always pairs with the preposition o plus the Locative case. So in this specific phrase, it translates to "depends on".
What case is tebi in this sentence?
It is in the Locative case. The preposition o requires the Locative case here. For the pronoun ti (you), the Locative full form is tebi. Note that the Dative and Locative forms of personal pronouns look exactly the same!
Why is the verb ovisi in the singular form?
The subject of the sentence is Sve (everything). In Croatian, just like in English, the word for "everything" is treated grammatically as a single thing. Therefore, it takes the third-person singular (he/she/it) form of the verb.
