I thought it was just one of those fun Appalachian phrases until I went to England and realized…Nope – it came across the Big Pond with so many other words and cultures. It’s a phrase used for ‘I think”
“I reckon I’ll make a pone of cornbread to go with them beans”
This use of ‘reckon’ is very different than something like a ‘reckoning’ which deals more with judgement.
Around my neck of the woods the first form is used a lot. Have you ever heard it before?
