Language standardization

A standard language or standard variety may be defined either as a language variety used by a population for public purposes or as a variety that has undergone standardization. Typically, varieties that become standardized are the local dialects spoken in the centers of commerce and government, where a need arises for a variety that will serve more than local needs. Standardization typically involves a fixed orthography, codification in authoritative grammars and dictionaries and public acceptance of these standards. A standard written language is sometimes termed by the German word Schriftsprache.

A pluricentric language has multiple interacting standard varieties. Examples include English, French, Portuguese, German, Korean, Spanish, Swedish, Armenian and Chinese. Monocentric languages, such as Russian and Japanese, have only one standardized version.

A standard variety is developed from a group of related varieties. This may be done by elevating a single variety, such as the local variety of a center of government or culture. Alternatively, a new variety may be defined as a selection of features from existing varieties. A fixed orthography is typically created for writing the variety. It may be codified in normative dictionaries and grammars, or by an agreed collection of exemplary texts. Whether these dictionaries and grammars are created by private individuals (like Webster's Dictionary) or by state institutions, they become standard if they are treated as authorities for correcting language. A fixed written form and subsequent codification make the standard variety more stable than purely spoken varieties, and provide a base for further development or ausbau. This variety becomes the norm for writing, is used in broadcasting and for official purposes, and is the form taught to non-native learners.
