That’s exactly how I pronounce the word, and I can’t stand when it’s pronounced “ant”. That’s a bug. Say the words “gaunt”, “daunt”, “flaunt”, “haunt”, “jaunt”, “taunt” and then “aunt”. They should all rhyme!
This is English - it doesn’t have to rhyme with those words at all. We spell lots of words unlike their pronunciation.
“ant” is correct. Saying “awnt” is like you’ve only seen the word spelled, but never heard it said out loud by anyone, especially Auntie Mame.
What's next here, toe∙MAY∙toe v. toe∙MAH∙toe?
If ant or awnt bother you, don't come to Pennsylvania, where one can hear shanty as SHAN∙dee and mountain as MAO∙din.
