The prepositions in Italian are classically nine. Classically because many adverbs can be used as prepositions, alone or in conjunction with a real preposition (e.g: sopra il tavolo [upon the table], prima di adesso [before now]). In modern Italian there's no more difference between tra and fra (the former meaning "between" and the latter meaning "among"): they are interchangeable: the only rule is euphony: tra fratelli (among brothers) vs. fra i tralicci (between the power pylons).
