Questions & Answers about On ide kući s bratom.
Do I have to say "On," or can I drop the subject?
You can drop it. Croatian usually omits subject pronouns because the verb ending shows the person. Ide kući s bratom is fully natural. Keep On if you want emphasis or to avoid ambiguity about who is going.
Why is it kući and not kuću?
- kući is the dative/locative singular of kuća and is used adverbially to mean “(to) home / homeward.” With motion verbs, idem/ideš/ide kući = “I/you/he is going home.”
- kuću is the accusative singular and means “(a/the) house” as a direct object or with a preposition meaning “into the house.”
Examples:
- Vidim kuću. = I see a house.
- Idem kući. = I’m going home.
- Idem u kuću. = I’m going into the house (i.e., entering the building).
Why is there no preposition before kući?
Because kući itself carries the “to home” meaning. For location (not motion), use:
- On je kod kuće. = He is at home.
- Don’t say u kući to mean “at home”; u kući means “in the house (building).”
What case is s bratom, and why?
It’s instrumental singular. The preposition s/sa + instrumental means “with (in company of).”
