I am not fluent in Italian, and even if I were, I would probably still make some mistakes. So please feel free to e-mail me if you find any errors.
Stare means to be when used in progressive tense.
If you use it with a present participle, it translates to something is happening, not something happens as with the present indicative. Conjugate stare and form the present participle, and you have a progressive action. Sto parlando italiano is I am speaking Italian . The easiest way to ask a question is to add a question mark to the end of the statement. Or you can put the subject at the end of the sentence.
