Questions & Answers about To se desilo juče.
To is a neuter singular demonstrative pronoun. In this sentence, it is the subject, so it is in the nominative.
A useful thing to notice is that the verb form agrees with it:
- to → neuter singular
- desilo → neuter singular past form
So the sentence is built to match grammatically.
Se is part of the verb desiti se, which means to happen.
So you should learn desiti se as a whole expression, not as desiti plus a separately translatable se.
In other words:
- desiti se = to happen
In this sentence, se does not mean itself in the way an English learner might first assume. It is simply part of the Serbian verb.
