Older Southern American English

Older Southern American English was a set of American English dialects of the Southern United States, primarily spoken by white Americans up until the American Civil War, moving towards a state of decline by the turn of the nineteenth century, further accelerated by World War II and again, finally, by the Civil Rights Movement. These dialects have since largely given way, on a larger regional level, to a more unified and younger Southern American English, notably recognized today by a highly unique vowel shift and certain other vocabulary and accent characteristics. Some features unique to older Southern U.S. English persist today, though typically in only very localized dialects or speakers.

This dialects of American English evolved over a period of four hundred years, primarily from older varieties of British English spoken by those who initially settled the area. Given that language is an entity that is constantly changing, the English of the colonists was quite different from any variety of English being spoken today. The colonists who initially settled the Tidewater area spoke a variety of Early Modern English, which itself was very varied. The older Southern dialects thus originated in large part from a mix of immigrants from the British Isles, who moved to the South in the 17th and 18th centuries, and the creole or post-creole speech of African slaves.

The earliest English settlers of the colonies of Virginia and Massachusetts were mainly people from Southern England. However, Virginia received more colonists from the English West Country, bringing with them a distinctive dialect and vocabulary.
