I find it strange that it is the only "a u n t" word that is not pronounced phonetically or with emphasis on all of the vowels. Examples:

chaunt
daunt
Gauntlet
flaunt
haunt
jaunt
taunt

I do not imagine people say,
“What a pretty afternoon, let’s go for a jant, shall we?”
“Wow, that was a dant ing task.”
“If you’ve got it, flant it!”

A majority usage does not make it a grammatical rule. It just means a lot of people say it incorrectly in my opinion, but whatever. It is not a big deal. I shall simply revel in my correctness and laugh at everyone else as they run through the gantlet of the english language and flant their poor pronunciations. I hope no one is upset by my tanting.

PS
Im regards to “ask,” I know black and white people that drop the “sk” and replace it with an “x.” But, I do not a lot of blacks that say “ax” as opposed to “ask.” On the other hand, I know a lot of white people that replace the “k” with an additional “s.” It makes for some great self entertainment. “Hey, Bobby, let me ass you?” “Yeah, go ahead.”
