Pittsburgh Speech and Pittsburghese [PDF ebook] 

Linguists have sporadically noted peculiarities of pronunciation, lexis and morphosyntax in the speech of European Americans in the Pittsburgh area, and Pittsburgh speech, locally known as “Pittsburghese”, has been a topic of discussion in the Pittsburgh area for decades. This variety has never before been systematically documented, however. The first and only scholarly book to describe Pittsburgh-area varieties of English, Pittsburgh Speech and Pittsburghese is an essential reference tool for anyone studying the dialect of the Pittsburgh area and the only textbook choice for anyone teaching about it.
