Questions & Answers about Treba mi nešto.
Here treba means something like is needed or is necessary.
So Treba mi nešto is literally closer to:
- Something is needed to me
- more naturally in English: I need something
This is a very common Serbian way to express need. Instead of using a verb exactly like English to need, Serbian often uses trebati in an impersonal-style construction.
Mi is the short clitic form of meni, which means to me.
In this sentence, the person who has the need is not in the nominative (ja = I), but in the dative:
- meni / mi = to me
So:
- Treba mi nešto = Something is needed to me = I need something
This is why ja does not appear here. The structure is built around treba + dative person + thing needed.
