I need help pronouncing this
Depends if you want the modern Latin pronunciation or the original Latin pronunciation. I favour the original, which would be something like:
FOR-tess for-TOO-nah AHD-yoo-waht
The modern, somewhat anglicised, Latin would be more like:
FOR-tezz fort-YOO-na AD-yoo-vat
You take your pick.
Fortes Fortuna Adiuvat
