Ciao!:D I quite sure that it would be "Mi sto insigniando italiano" but I think it would be better to say "Sto imparando italiando da solo" (I'm learning Italian on my own), otherwise it would sound like a really rough translation. I hope it was useful!:) Take care!:D Ana:)

イタリア語を一人で習っています。 Sto imparando l'italiano da sola. イタリア語を私に教えています。間違えです。E' errato Mi sto insegnando l'italiano. 間違えです。E' errato. イタリア語を私に教えませ。間違え Mi insegno l'italiano　間違え 教えます= insegnare 教えています= sto insegnado 習います= imparare,etc etc 習っています= sto imparando イタリア語勉強がんばってください またこんど 猫ちゃん

The best way to say that in italian is "sono autodidatta in italiano" or "studio l'italiano da autodidatta". As Italian mother-tongue I would never use other forms. Moreover please be informed that autodidattA is equal for both masculine and feminine nouns.

The literary translation is "Sto insegnandomi l'italiano"/"Mi insegno l'italiano" but in Italian really don't sound fine so: "Sono autodidatta in italiano" "Studio (l')italiano da autodidatta" "Studio (l')italiano da solo/a" to teach= insegnare to learn = imparare, apprendere :-)

Giusto Ana !!! L'espressione corretta è: "Sto imparando l'italiano da solo"
