Questions & Answers about Sinkronizacija je spremna.
Because Croatian usually uses the verb biti (to be) in sentences like X is ready, X is good, X is important, etc.
So:
- On je umoran. = He is tired.
- Kuća je velika. = The house is big.
- Sinkronizacija je spremna. = The synchronization is ready.
Unlike in some Slavic languages, Croatian normally does not drop is/are in the present tense in this kind of sentence.
