Grammar Rule in 30 Seconds
Use Accusative for movement toward a destination and Locative for staying in one place with the prepositions 'u' and 'na'.
- Movement (Where to? / Kamo?): Use Accusative. Example: Idem u šumu (I am going into the forest).
- Static (Where? / Gdje?): Use Locative. Example: Šetam u šumi (I am walking in the forest).
- U vs Na: 'U' is for enclosed spaces; 'Na' is for surfaces, events, and open areas.

Smart Tips
Use 'na kavu' or 'na ručak' even if you are going inside the building, because you are focusing on the event.
Instantly recognize it as movement or a destination.
Always use 'na poslu' (at work) and 'na posao' (to work). Never use 'u'.
Remember that Locative always adds an -u, while Accusative (for things) stays the same as the dictionary form.

チャレンジ
Look around your room. Name 3 things you can put 'na stol' (Acc) and 3 things that are already 'u ormaru' (Loc).
文化メモ
In coastal regions, people might use 'na' more frequently for locations that would take 'u' in standard Croatian, reflecting Italian influence.
The 'kajkavian' influence often leads to shorter vowels in endings, but the Acc/Loc distinction remains strict.
The phrase 'Idem na kavu' (I'm going for coffee) is a social institution. It doesn't always mean you will drink coffee; it means you are going to socialize.
Derived from Proto-Slavic *vъ (in) and *na (on). The case distinction (Acc/Loc) is a common Indo-European heritage shared with Latin and Greek.

よくある質問 (8)
In Croatian, 'posao' (work) is seen as an activity or status, which takes 'na'. 'Ured' (office) is a physical building/room, which takes 'u'.
Generally, no. It sounds very wrong to native speakers. Always use `na` for islands like Hvar, Krk, or Korčula.
The rule still applies! For example, `u šume` (into the forests - Acc) vs. `u šumama` (in the forests - Loc).
Both are used, but `u ljeto` (Locative) means 'during the summer', while `na ljeto` (Accusative) often means 'this coming summer'.
Think: Is it a container (u) or a surface/event (na)? When in doubt, most buildings are 'u' and most open spaces are 'na'.
Yes! 'Iz' (from inside) is the opposite of 'u', and 'sa' (from surface) is the opposite of 'na'.
Countries take 'u', but peninsulas (like the Balkans) take 'na' because they are viewed as geographical surfaces.
If you are already in the room and just walking around, use Locative: `Hodam u sobi`. If you are entering the room, use Accusative: `Ulazim u sobu`.

Wechselpräpositionen (in/auf + Akk/Dat)
German uses Dative for location, while Croatian uses Locative.
en
Spanish has no case endings for nouns.
dans / sur / à
French uses different prepositions rather than noun cases to show direction.
ni (に) / de (で) / he (へ)
Japanese particles follow the noun and don't change the noun's form.
fi (في) / 'ala (على)
The preposition itself doesn't trigger a movement-specific case in the same way.
zài (在)
Chinese has no cases or gender, making this a very difficult concept for native speakers.
