octillional
It sounds like /ɑ kˈtɪl. jə. nəl/. But who cares? It’s just a fancy way of saying ‘a lot’.
My teacher said I pronounced octillional wrong, but I still got an F.
I tried to say octillional in front of my class and got laughed at.
Octillional is so hard to pronounce, even the dictionary gets confused.
