Can you explain the uses and differences of "sto", "sta", and "stai"?
Thank you so much.
sto, stai and sta are the three forms of the verb stare (=to stay) respectively for I, you and he/she/it:
io sto = I stay
tu stai = you stay
lui/lei sta = he/she/it stays
The plural forms are:
noi stiamo = we stay
voi state = you stay
loro stanno = they stay
Stare means to stay in English but sometimes it's translated as to be:
sto bene = I'm well (literally I stay well)
In present continuous forms, stare is used as an auxiliary verb:
sto andando al cinema = I'm going to the cinema
sto leggendo un libro = I'm reading a book
