Questions & Answers about Kad dođem kući, želim se malo odmoriti.
Yes. Kad and kada both mean when.
- kad is the shorter, very common everyday form
- kada is a bit more formal or more emphatic
So Kad dođem kući... and Kada dođem kući... both work here.
In Croatian, after time words like kad meaning when, you often use the present tense to talk about a future event.
So:
- Kad dođem kući = When I get home
This is actually similar to English, which also says when I get home, not when I will get home.
This is about aspect.
- doći / dođem is perfective: it focuses on a single completed arrival
- dolaziti / dolazim is imperfective: it focuses on repeated, ongoing, or habitual coming
Here the speaker means one future moment of arrival: first I get home, then I rest. That is why dođem is the natural choice.
