Nonstandard dialect

Vernacular is the ordinary, informal, spoken form of a language or dialect. The term particularly carries the perception of a language variety with 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 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. Less commonly, vernacular can also refer to written language that intentionally reflects or imitates the aforementioned form of spoken language.
