Because they talk with their teeth together
Boston accent is pretty sharp as are most northern accents
What a lot of folks don’t realize is that there is a distinct difference between a country accent which basically means someone not taught decent grammar in the South and a true Southern accent and they overlap
A southern accent TN accent is distinct from Texas and is divided between Bristol to Cookeville, Cookeville to the Tennessee River and Tennessee River to Missisissippi River which the latter is more like a Mississippi delta accent ...law oong and draaaawn out
Given the recent northern invasion of the desirable urban southern areas our accents are fading quick from the Piedmont to Nashville to Austin
I prefer Deep South literary accent pleasantries and Minnesota and Southern California beachy tones
I’m fond of Brooklyn Italian speech but I wouldn’t call it pleasing to the ear
In Texas it seemed to me a real southern accent was mostly east Texas and north Dallas....you hear more southern in Dallas than Brentwood TN
The rest of Texas is more a country accent that gets drier as you go further West....Oklahoma ditto same thing
But it really is hard to distinguish purely southern from country sometimes
Like Ben Johnson the actor from Oklahoma had a mix of southern and country tone
Lindsey Graham has a southern accent
The actor Tommy Lee Jones has a Texas country western sounding accent....southern but different
I’m between Knoxville and Chattanooga in the foothills of the Smokies. What Southern dialect am I? I don’t have the “country” accent even though I live in a rural area but I know the accent you are talking about. My grandmother and grandmother had that. I don’t like bad grammar regardless of where a person lives but people from my grandparents generation in rural TN normally made it through 8th grade because they spent most of their time being farm hands.
