Learn Croatian: Želimo ići u muzej. - We want to go to the museum.

In Croatian, you usually drop the pronoun (like mi for 'we') because the verb ending already tells you who is doing the action. The -mo ending on želimo clearly means 'we want'.

Why do we use u here to mean 'to' the museum?

When talking about going to a destination, Croatian uses u (which often means 'in' or 'into') for enclosed spaces like buildings, cities, and countries. Since a museum is a building you go inside, we use u.

The lesson says we need the accusative case after u for a destination. Why didn't the word muzej change its ending?

Muzej actually is in the accusative case here! For masculine nouns that are non-living objects or places (inanimate), the accusative form is exactly the same as the basic dictionary form. The ending would only change if the masculine noun was a living being.

Why is ići used in its basic dictionary form (infinitive)?

Just like in English ('want to go'), when you use two verbs together where the first expresses a desire, the second verb stays in its base infinitive form. Here, želimo changes to match 'we', so ići stays as the infinitive.
