Vediamo: Mi and ti are both pronouns, object pronouns and reflexive pronouns. The equivalence would be: Riflexive io=mi, tu=ti, lei, lui,Lei,=si, noi-=ci, voi=vi, loro=si. / Object pronouns: mi, ti, lo,la,ci, vi, loro In any phrase you have the subject (the one who acts) and the object( the one who receive the action). "I'm telling you !" ( I am telling something to you). In Italian, is the same, and we have different pronouns weather for subjects and objects, like in English. You don't say " I'm talking to he, but I'm talking to HIM". The same in Italian, and the pronoun could be either before or after the verb. If the pronoun goes BEFORE you must use the "atonal" version (mi) if it goes AFTER the verb the tonic verssion (me). Example: ti vedo / vedo te la/la vedo / vedo lei ( o lui, if masculin) ci vediamo / vediamo noi. Reflexive form: " I wash my hands" ( mi lavo le mani) The actor and recipient are the same, and instead of the personal pronoun "io" we use the reflexive particle "mi" and we keep the verb in first person, so we know that the speaker and the recipient are the same ones. In italian, is not always mandatory to use the personal pronoun. You can say "vado a Roma" e non debi usare il "io", unless you want to emphasize that "YOU" go to Rome, after all or above all circumstances. "Sto" is the first person singular of verb stare (to stay, to be, to remain) with a sense of permanence but frequently used in colloquial phrases as " Sto male, sto bene", "Io ci sto" and so on. Stare is a tricky verb, and should be use with care and prudence. Un abbraccio
