Language policyLanguage policy is an interdisciplinary academic field. 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 used to be known as language planning and is related to other fields such as language ideology, language revitalization, language education, among others.
Language contactLanguage contact occurs when speakers of two or more languages or varieties interact with and influence each other. The study of language contact is called contact linguistics. When speakers of different languages interact closely, it is typical for their languages to influence each other. Language contact can occur at language borders, between adstratum languages, or as the result of migration, with an intrusive language acting as either a superstratum or a substratum.
Language planningIn sociolinguistics, language planning (also known as language engineering) is a deliberate effort to influence the function, structure or acquisition of languages or language varieties within a speech community. Robert L. Cooper (1989) defines language planning as "the activity of preparing a normative orthography, grammar, and dictionary for the guidance of writers and speakers in a non-homogeneous speech community" (p. 8).
Cultural genocideCultural genocide or culturicide is a concept which was proposed by lawyer Raphael Lemkin in 1944 as a component of genocide. Though the precise definition of cultural genocide remains contested, the Armenian Genocide Museum defines it as "acts and measures undertaken to destroy nations' or ethnic groups' culture through spiritual, national, and cultural destruction". Some ethnologists, such as Robert Jaulin, use the term ethnocide as a substitute for cultural genocide, although this usage has been criticized as risking the confusion between ethnicity and culture.
MultilingualismMultilingualism is the use of more than one language, either by an individual speaker or by a group of speakers. It is believed that multilingual speakers outnumber monolingual speakers in the world's population. More than half of all Europeans claim to speak at least one language other than their mother tongue; but many read and write in one language. Multilingualism is advantageous for people wanting to participate in trade, globalization and cultural openness.
EthnologueEthnologue: Languages of the World (stylized as Ethnoloɠue) is an annual reference publication in print and online that provides statistics and other information on the living languages of the world. It is the world's most comprehensive catalogue of languages. It was first issued in 1951, and is now published by SIL International, an American evangelical Christian non-profit organization. Ethnologue has been published by SIL International (formerly known as the Summer Institute of Linguistics), a Christian linguistic service organization with an international office in Dallas, Texas.
Linguistic purismLinguistic purism or linguistic protectionism is the prescriptive practice of defining or recognizing one variety of a language as being purer or of intrinsically higher quality than other varieties. Linguistic purism was institutionalized through language academies (of which the 1572 Accademia della Crusca set a model example in Europe), and their decisions often have the force of law. The perceived or actual decline identified by the purists may take the form of a change of vocabulary, syncretism of grammatical elements, or loanwords.
Indigenous languageAn indigenous language, or autochthonous language, is a language that is native to a region and spoken by indigenous peoples. This language is from a linguistically distinct community that originated in the area. Indigenous languages are not necessarily national languages but they can be; for example, Aymara is an official language of Bolivia. Also, national languages are not necessarily indigenous to the country.
Regional languageA regional language is a language spoken in a region of a sovereign state, whether it be a small area, a federated state or province or some wider area. Internationally, for the purposes of the European Charter for Regional or Minority Languages, "regional or minority languages" means languages that are: traditionally used within a given territory of a State by nationals of that State who form a group numerically smaller than the rest of the State's population and different from the official language(s) of that State Recognition of regional or minority languages must not be confused with recognition as an official language.
Minority languageA minority language is a language spoken by a minority of the population of a territory. Such people are termed linguistic minorities or language minorities. With a total number of 196 sovereign states recognized internationally (as of 2019) and an estimated number of roughly 5,000 to 7,000 languages spoken worldwide, the vast majority of languages are minority languages in every country in which they are spoken. Some minority languages are simultaneously also official languages, such as Irish in Ireland or the numerous indigenous languages of Bolivia.
