Regionalism and dialect, help!?!?

Question

what is the difference between a standard english sentence, a dialect sentence, and a regionalism sentence, please give examples, and for the people out there that are going to say look it up on your own, just don't write anything, i am studying for a big test and i have been for a couple months, i just want your opinion on what these terms mean, and like i said, please show examples.

Answer 1

"How are you doing?" Standard English sentence

"How y'all doing?" Same sentence given a Southern regional influence.

"How yawl doon?" Same sentence in dialect, or the phonetical version of a regional saying.
