Questions & Answers about Želim ti sreću.
- Želim = I wish / I want. It is the 1st person singular present tense of želeti.
- ti = to you / you in the dative case.
- sreću = luck in the accusative case.
So the structure is basically:
I wish + to you + luck
which matches the English idea I wish you luck.
In Serbian, subject pronouns are often left out because the verb ending already shows who the subject is.
- želim already means I wish
- so ja is not necessary
You can say Ja želim ti sreću, but it usually sounds more emphatic, as if you are stressing I.
The neutral, natural version is simply:
Želim ti sreću.
