A standard language (or standard variety, standard dialect, standardized dialect or simply standard) is any language variety that has undergone substantial codification in its grammar, lexicon, writing system, or other features and that stands out among related varieties in a community as the one with the highest status or prestige. Often, it is the prestige language variety of a whole country.
In linguistics, the process of a variety becoming organized into a standard, for instance by being widely expounded in grammar books or other reference works, and also the process of making people's language usage conform to that standard, is called standardization. Typically, the varieties that undergo standardization are those associated with centres of commerce and government, used frequently by educated people and in news broadcasting, and taught widely in schools and to non-native learners of the language. Within a language community, standardization usually begins with a particular variety being selected (often towards a goal of further linguistic uniformity), accepted by influential people, socially and culturally spread, established in opposition to competitor varieties, maintained, increasingly used in diverse contexts, and assigned a high social status as a result of the variety being linked to the most successful people. As a sociological effect of these processes, most users of a standard dialect—and many users of other dialects of the same language—come to believe that the standard is inherently superior to, or consider it the linguistic baseline against which to judge, the other dialects. However, such beliefs are firmly rooted in social perceptions rather than any objective evaluation. Any varieties that do not carry high social status in a community (and thus may be defined in opposition to standard dialects) are called nonstandard or vernacular dialects.
