Coincidentally, a lifetime ago in college a visiting prof from NC filled in for a lecture. After a while, I kept thinking how very English he sounded. It was so distracting that I paid no attention to what he was saying.
Then again, there was nothing new there.
Google 'Highland Southern dialect'.
There are still pockets of old timers in the hills that retain an Elizabethan flavor to their speech.
As one example, whereas "regular" Southrens say "y'all", HSers will instead say "yee'll" as in "Ye all" or "ye will", depending.
Due to the very heavy Scots-Irish influence, our speech is much more "sing song" [though we prefer to call it melodious] than "plain" English.
I myself had a devil of a time getting used to the Southren tendency to end every sentence on an ascending note as though it were a question rather than a statement.
I found myself mentally dissecting the grammar/context of a sentence to decide how it should be answered....;))
HSers write differently too.
For years I'd spell "favor" as "favour" and had to retrain myself because I got tired of online friends asking if I was British.....:)
And then there's the "unique" syntax.
Instead of saying "please throw a towel up to me" it's "please throw me up a towel".
[and to be honest, "throw" mutates into "thow"]
Most annoying to DH is the chronic vowel/consonent/entire word "dropping" of an HSer wife in a hurry.
"Give that to me" becomes "givuhtummy" and even that "word" just *barely* manages to include the 4 syllables it appears to have.
We're nothing if not verbally thrifty.
Now, please thowatowel uptummy....:)
This is funny but dead-on;
