It's actually quite similar to how it works in English: I -> Io, subject am -> sto, auxiliary verb (in this case Italian does not use "essere" (to be) but "stare") learning -> imparando, main verb in the past participle in English, in the "gerundio presente" tense. The "gerundio" tense is recognisable by the fact that it ends in -ndo (mangiando, tenendo, correndo). Ciao

You can say i'm learning italian: Io sto imparando l'italiano. ciao
