Questions & Answers about Kad dođe majstor, složit ćemo novi ormar u sobi.
Dođe is present tense, 3rd person singular, from the verb doći (to come / to arrive).
What can confuse English speakers is that Croatian often uses the present tense of a perfective verb to talk about a future event, especially after words like kad (when).
So in:
Kad dođe majstor...
the meaning is:
When the repairman/worker arrives...
not when he came.
A useful idea is:
- doći = perfective, one completed arrival
- dolaziti = imperfective, ongoing/repeated coming
Here, the sentence is about a single future arrival, so dođe is the natural choice.
