Questions & Answers about Sada mi je bolje.
- Sada = now
- mi = to me / for me (short dative form of ja)
- je = is (3rd person singular of biti, to be)
- bolje = better
Literally, the structure is closer to Now it is better to me, which Serbian uses for the idea I feel better now or I’m better now.
Because Serbian does not express this idea the same way English does.
In English, you say I am better with I as the subject.
In Serbian, this expression is usually built more like It is better to me:
- meni je bolje = I feel better / it’s better for me
- short form: mi je bolje
So mi is not the subject. It is a dative pronoun meaning to me / for me.
Mi is the dative singular form of ja.
Here are the relevant forms:
- ja = I (nominative)
- mene / me = me (accusative/genitive)
- meni / mi = to me / for me (dative)
In Sada mi je bolje, Serbian uses the dative because the idea is about someone’s state or experience: it is better to me / for me.
