Standardization
The procedure via which standard forms of a language are settled up and maintained is called language standardization.
Standardization can happen as a natural evolution of a language in a speech community or as an attempt by community members to impose one dialect or variety as a standard.
Standardization refers to linguistic forms (corpus planning, i.e., selection and codification) and also the social and communicative functions of language (status planning, namely implementation, and elaboration) [ThoughtCo].
Standardization is the natural evolution of a standard language in a speech community (or a try by this community to impose one dialect as a standard) [Crystal, p. 450].
Standardization is typically used in linguistics, referring to creating a standard language. This process brings to a language a constancy and consistent norm and shape of writing and speaking, and the promotion of constancy and consistency typically causes the reduction or removal of variation. The standard language—especially the written mode—is integral to national identity [Oxford Bibliographies].
