Questions & Answers about To je tema o kojoj svi stalno raspravljaju.
Why is the relative pronoun kojoj used here instead of koja?
Kojoj refers back to the noun tema (topic), which is feminine and singular. It is in the locative case here because it follows the preposition o (about). You must match the gender and number of the noun, and use the case that the preposition demands.
The English translation says "the topic everyone is discussing", but the Croatian sentence has o kojoj. Why is the o there?
In English, we often drop "about which" or put the preposition at the very end (like "the topic everyone is talking about"). In Croatian, you cannot leave prepositions dangling at the end of a sentence. The verb raspravljati (to discuss) requires the preposition o (about), so it must go right before the relative pronoun, forming o kojoj (about which).
Why is the verb raspravljaju in the plural form when "everyone" is singular in English?
In English, "everyone" takes a singular verb. However, the Croatian word svi literally translates to "all" (the plural form of sav). Because svi is plural, the verb must also take the "they" form, which is raspravljaju (they discuss).
If tema is a feminine noun, why does the sentence start with the neuter word To instead of the feminine Ta?
