My dialect, being from Pittsburgh?
You've probably heard of it, no matter where you're from.
Family flew out to Morgan Hill, CA for my brother's wedding in '04. The receptionist in the hotel lobby said, "Ah, you from Pittsburgh?"...doh.
Believe it or not, there's a
Wikipedia entry on it.
(I use most of the words in the 'vocabulary' section..lol)
Even when I think about it, I don't consider myself to be talking improper
english. I do catch myself, however, using "Yinz" and "N'nat"...
The
phrases page of Pittsburghese.com explains it very well. Say some of 'em out loud, and you'll get it.
