Editing General American English (section)

===Regional origins===
Though General American accents are not commonly perceived as associated with any region, their [[phonology|sound system]] does have traceable regional origins: specifically, the English of the non-coastal [[Northeastern United States]] in the very early 20th century, which was relatively stable since that region's original settlement by English speakers in the mid-19th century.{{sfnp|Labov|Ash|Boberg|2006|p=190}} This includes western [[New England]] and the area to its immediate west, settled by members of the same dialect community:{{sfnp|Bonfiglio|2002|p=43}} interior [[Pennsylvania]], [[Upstate New York]], and the adjacent "[[Midwestern United States|Midwest]]" or [[Great Lakes region]]. However, since the early to mid-20th century,{{sfnp|Wells|1982|p=470}}<ref>{{cite magazine|url=http://www.newyorker.com/archive/2005/11/14/051114ta_talk_seabrook|magazine=[[The New Yorker]]|title=Talking the Tawk|year=2005|publisher=Condé Nast}}</ref> deviance away from General American sounds started occurring, and may be ongoing, in the eastern Great Lakes region due to its [[Northern Cities Vowel Shift]] (NCVS) towards a unique [[Inland North|Inland Northern accent]] (often now associated with the region's urban centers, like Chicago and Detroit) and in the western Great Lakes region towards a unique [[North Central American English|North Central accent]] (often associated with [[Minnesota]], [[Wisconsin]], and [[North Dakota]]).
