Seeing as how we speak English which was originally from "England", a lot of Brits say it "Ont", and not Ant. It should rhyme with Flaunt, Aunt. Ant is Ant. The Dictionary lists both pronunciations, but I believe if you were to speak it in the purist sense, it would be Aunt. Ant is just been tolerated for so long that no one has really questioned it. It's the same as Caribbean "Care i bee in" or "Ka rib ee' in". The last pronunciation is probably more accurate as it was named after the Carib Indians. (That's "Kairib"). Accents and Inflections has slowly changed how the word was perceived in the first place.
