Look at this example.
In English I say: “I have been to home today”
In Italian I can say:
“Io sono statA a casa oggi” (A female speaks)
“Io sono statO a casa oggi” (A male speaks)
So ipotize to read a book that starts with:
“I have been to home today my friends …”
You can not know if a male ora a female is speaking.
But if I read the same statement in an Italian book I will read:
“Io sono stata a casa oggi.” So I immediately know that a female is speaking.
or in the other case:
“Io sono stato a casa oggi…” (I know that a male is speaking)
do you know that?
