Questions & Answers about Račun s markom i modelom dokaz je vlasništva.
Because the preposition s meaning with normally takes the instrumental case in Croatian.
So:
- marka → markom
- model → modelom
That is why you get:
- s markom = with the brand
- s modelom = with the model
When two nouns are joined by i (and), both stay in the same case:
- s markom i modelom = with the brand and model
This is very common in Croatian:
- s prijateljem = with a friend
- s knjigom = with a book
