vernacular

Vernacular is the ordinary, informal, spoken form of a language or dialect, particularly when perceived as having lower social status or less prestige than standard language, which is more codified, institutionally promoted, literary, or formal. More narrowly, any particular variety of a natural language that does not hold a widespread high-status perception, and sometimes even carries social stigma, is also called a vernacular, vernacular dialect, nonstandard dialect, etc. and is typically its speakers' native variety. Regardless of any such stigma, all nonstandard dialects are full-fledged varieties of language with their own consistent grammatical structure, sound system, body of vocabulary, etc.

==Overview== Like any native language variety, a vernacular has an internally coherent system of grammar. It may be associated with a particular set of vocabulary, and spoken using a variety of accents, styles, and registers. As American linguist John McWhorter describes about a number of dialects spoken in the American South in earlier U.S. history, including older African-American Vernacular English, "the often nonstandard speech of Southern white planters, nonstandard British dialects of indentured servants, and West Indian patois, [...] were nonstandard but not substandard." In other words, the adjective "nonstandard" should not be taken to mean that these various dialects were intrinsically incorrect, less logical, or otherwise inferior, only that they were not the socially perceived norm or mainstream considered prestigious or appropriate for public speech; however, nonstandard dialects are indeed often stigmatized as such, due to socially-induced post-hoc rationalization. Again, however, linguistics regards all varieties of a language as coherent, complex, and complete systems—even nonstandard varieties.
