In Italian, the pronoun ne can mean "about," "any," "some," "of it," "of them," from it," from them," or "from there." It can also replace a prepositional phrase beginning with da or di. Here are a few examples:

Parliamo di Mario. (We talk about Mario.)

Ne parliamo. (We talk about him.)

Hai bisogno di due francobolli. (You need two stamps.)

Ne hai bisogno di tre. (You need two of them.)

Avete molti amici. (You have many friends.)

Ne avete molti amici. (You have many of them.)

Ho due fratelli. (I have two brothers.)

Ne ho due. (I have two of them.)
