Questions & Answers about Ideš li večeras na koncert?
Why do we use na instead of u for 'to the concert'?
In Croatian, we use na for open spaces, islands, and events or activities. Because a concert is an event rather than a physical building you go inside, it takes na.
Wait, shouldn't koncert be in the accusative case here since it's a destination?
It is in the accusative case! For masculine nouns that are non-living (like koncert), the accusative form is exactly the same as the dictionary form. You only add a new ending for living things (like animals or people).
Why do we need the word li here?
The word li is a small particle used to form yes/no questions. When you start a question with a verb like Ideš (you go), you place li right after it to make it a question: Ideš li...? (Are you going...?).
Is the word večeras related to večer (evening)?
Yes! večeras specifically means 'this evening' or 'tonight'. You will see this -as ending on other time words too, like danas (today) which comes from dan (day).
