Really hoping someone can help me understand the Japanese grammar particles.

の = Possession

は = Topic Marker

に = Marks a specific time

Those are the ones I know, except for は a little bit.  By a little bit I mean that I don't know which word it needs to follow in a sentence to be grammatically correct.
