Language policy is both an interdisciplinary academic field[1] and implementation of ideas about language use.[2] Some scholars such as Joshua Fishman and Ofelia García consider it as part of sociolinguistics. On the other hand, other scholars such as Bernard Spolsky, Robert B. Kaplan and Joseph Lo Bianco argue that language policy is a branch of applied linguistics.
As a field, language policy is also known as language planning or language policy and planning,[1] and is related to other fields such as language ideology, language revitalization, and language education, among others.
Language policy can be defined as the combination of official decisions and prevailing public practices related to language education and use.
