Stressed or Clitic Pronouns

Italian has two sets of object pronouns.

The short clitic forms (mi, ti, lo, la, ci, vi, li, le, gli) stand directly before the conjugated verb: Marco mi aspetta (Marco is waiting for me), Non lo conosco (I don't know him).

The stressed forms (me, te, lui, lei, noi, voi, loro) are used:

• after a preposition: con me, per te, secondo me, a me piace
• after the verb, to stress or contrast: Chiamano te, non Marco (They're calling you, not Marco).

Only io and tu change their form: never say con io or per tu. The other stressed forms look exactly like the subject pronouns.
