I was interested enough in the etymology to do some googling; terrific has its roots in ‘terror’, much like horror/horrific. It was used as a generic intensifier, often hyperbolically, which became common enough that it lost its negative connotation.
Yep it's the same in italian, it means "generating strong fear" or alike. But at this point I got accustomed to the English meaning when I write English.
The original meaning of awful used to be awe-inspiring too. Awesome came about as a replacement when awful started acquiring significant negative connotations.
