A
standard dialect (also known as a
standardized dialect or "standard language") is a dialect that is supported by institutions. Such institutional support may include government recognition or designation; presentation as being the "correct" form of a language in schools; published grammars, dictionaries, and textbooks that set forth a "correct" spoken and written form; and an extensive formal literature that employs that dialect (prose, poetry, non-fiction, etc.). There may be multiple standard dialects associated with a single language. For example, Standard American English, Standard British English, Standard Indian English, Standard Australian English, and Standard Philippine English may all be said to be standard dialects of the English language.
A nonstandard dialect, like a standard dialect, has a complete vocabulary, grammar, and syntax, but is not the beneficiary of institutional support. An example of a nonstandard English dialect is Southern English.
