Ant for me....
Born in Philadelphia, where that was more common than other parts of the country where I/we have live where the other was used
That's interesting. In my mind I was associating "ohnt" with Northern states and "Ant" with the South. This is my own personal Mythbusters :)
Now that I think about it, our Southern “ants” can sound a lot like “ain’ts”, depending on how country the niece or nephew is. eg: “Ain’t Bea” from The Andy Griffith Show.
