I don't know that anyone has defined the idiosyncrasies of prepositions. It's probably just idiomatic, developing that way because that's the way that became popular.

On a related note, you'll find that non-native speakers of a language almost always have the hardest time with prepositions, because each language's prepositional usages seem to be different from every other language's. I don't don't think that there really is any rhyme or reason.
