Learn Croatian: Želiš li sladoled u kornetu ili u čašici? - Do you want ice cream in a cone or in a cup?

The word sladoled is in the accusative case because it is the direct object of želiš. However, because it is a masculine inanimate noun (a non-living thing), its accusative form is identical to its nominative dictionary form. If it were a living masculine noun, it would take an -a ending.

Why does the sentence use u čašici instead of just u čaši?

Čašica is the diminutive form of čaša (glass or cup). In Croatian, ice cream served in a cup is naturally referred to using this diminutive because the containers are small. The noun is in the locative case here because of the preposition u.

Why are kornetu and čašici in the locative case after u rather than the accusative?

The preposition u takes the locative case when it describes a static location or state, like the ice cream resting inside the cone or cup. It only takes the accusative case when describing active motion into a destination.

Is the word kornet related to English?

Yes, it shares a root with the English word cornet (the brass instrument), both coming from the Italian word cornetto (little horn). However, in Croatian, kornet is the standard everyday word used specifically for an ice cream cone.
