I grew up in Florida, where I was extremely familiar with the city of St. Augustine... pronounced, Saint Aw-gus-teen.
I keep hearing Uh-gus-tin now that I'm in the RCC. I frankly can't see this pronunciation in any manner whatsoever based on the spelling. Is it a Latin vestige?
FWIW, this discussion is the exact reason I despise the English "language". I can't wait for the bastardization we know as English to die a fiery death. This is exactly why I want to learn Latin, and why, if I am ever gifted the responsibility of children, they will be polyglots.
e at the end of a word with "ine" = een, in my experience. English... ugh.
