North-Central American English

North-Central American English is an American English dialect, or dialect in formation, native to the Upper Midwestern United States, an area that somewhat overlaps with speakers of the Inland Northern dialect situated more in the eastern Great Lakes region. In the United States, it is also known as the Upper Midwestern or North-Central dialect and stereotypically recognized as a Minnesota accent or sometimes Wisconsin accent (excluding Wisconsin's Milwaukee metropolitan area).
