The dialect in my area is mostly Pittsburghese, but is also influenced somewhat more by Appalachian than is pure Pittsburghese. For instance "coulda", "woulda" and "shoulda" are common as are many of the Appalachian constructs, like "He ain't done nothin'". However, many for the words favored in Appalichian dialect like
polecat,
poke and
blinked are not used.
We do use many of the Pittsburghese words and pronunciations, but again, cetain setups and words are not favored against their Standard English counter parts.
