Language policy is an interdisciplinary academic field. Some scholars such as Joshua A. 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.
Language policy has been defined in a number of ways. According to Kaplan and Baldauf (1997), "A language policy is a body of ideas, laws, regulations, rules and practices intended to achieve the planned language change in the societies, group or system" (p. xi). Lo Bianco defines the field as “a situated activity, whose specific history and local circumstances influence what is regarded as a language problem, and whose political dynamics determine which language problems are given policy treatment” (p. 152). McCarty (2011) defines language policy as "a complex sociocultural process [and as] modes of human interaction, negotiation, and production mediated by relations of power. The ‘policy’ in these processes resides in their language-regulating power; that is, the ways in which they express normative claims about legitimate and illegitimate language forms and uses, thereby governing language statuses and uses" (p. 8).
Language policy is broad, but it can be categorized into three components. Spolsky (2004) argues, "A useful first step is to distinguish between the three components of the language policy of a speech community: (1) its language practices – the habitual pattern of selecting among the varieties that make up its linguistic repertoire; (2) its language beliefs or ideology – the beliefs about language and language use; and (3) any specific efforts to modify or influence that practice by any kind of language intervention, planning, or management" (p. 5).
The traditional scope of language policy concerns language regulation. This refers to what a government does either officially through legislation, court decisions or policy to determine how languages are used, cultivate language skills needed to meet national priorities or to establish the rights of individuals or groups to use and maintain languages.
The implementation of language policy varies from one State to another. This may be explained by the fact that language policy is often based on contingent historical reasons. Likewise, States also differ as to the degree of explicitness with which they implement a given language policy. The French Toubon law is a good example of explicit language policy. The same may be said for the Charter of the French Language in Quebec.
Scholars such as Tollefson argue that language policy can create inequality, "language planning-policy means the institutionalization of language as a basis for distinctions among social groups (classes). That is, language policy is one mechanism for locating language within social structure so that language determines who has access to political power and economic resources. Language policy is one mechanism by which dominant groups establish hegemony in language use" (p. 16).
Many countries have a language policy designed to favor or discourage the use of a particular language or set of languages. Although nations historically have used language policies most often to promote one official language at the expense of others, many countries now have policies designed to protect and promote regional and ethnic languages whose viability is threatened. Indeed, whilst the existence of linguistic minorities within their jurisdiction has often been considered to be a potential threat to internal cohesion, States also understand that providing language rights to minorities may be more in their long term interest, as a means of gaining citizens' trust in the central government.
The preservation of cultural and linguistic diversity in today's world is a major concern to many scientists, artists, writers, politicians, leaders of linguistic communities, and defenders of linguistic human rights. More than half of the 6000 languages currently spoken in the world are estimated to be in danger of disappearing during the 21st century. Many factors affect the existence and usage of any given human language, including the size of the native speaking population, its use in formal communication, and the geographical dispersion and the socio-economic weight of its speakers. National language policies can either mitigate or exacerbate the effects of some of these factors.
For example, according to Ghil'ad Zuckermann, "Native tongue title and language rights should be promoted. The government ought to define Aboriginal and Torres Strait Islander vernaculars as official languages of Australia. We must change the linguistic landscape of Whyalla and elsewhere. Signs should be in both English and the local indigenous language. We ought to acknowledge intellectual property of indigenous knowledge including language, music and dance."
There are many ways in which language policies can be categorized. It was elaborated by Université Laval sociolinguist Jacques Leclerc for the French-language Web site L'aménagement linguistique dans le monde put on line by the CIRAL in 1999. The collecting, translating and classifying of language policies started in 1988 and culminated in the publishing of Recueil des législations linguistiques dans le monde (vol. I to VI) at Presses de l'Université Laval in 1994. The work, containing some 470 language laws, and the research leading to publication, were subsidised by the Office québécois de la langue française. In April 2008, the Web site presented the linguistic portrait and language policies in 354 States or autonomous territories in 194 recognised countries.
