^Which is weird if you think about it, since Latin didn't pronounce the long i
like "eye," but like "ee." So if we were being authentic to Latin pronunciation, it would be "Aven-teen."
Except, come to think of it, the actual Latin word isn't Aventine
, but Aventinus
(specifically Collis Aventinus
, the Aventine Hill
). So "Aventine" is an English word derived from Latin, not a Latin word. Which I guess is why your teachers favored an English pronunciation.
