Linguistic homelandIn historical linguistics, the homeland or Urheimat (ˈʊərhaɪmɑːt, from German ur- "original" and Heimat, home) of a proto-language is the region in which it was spoken before splitting into different daughter languages. A proto-language is the reconstructed or historically-attested parent language of a group of languages that are genetically related. Depending on the age of the language family under consideration, its homeland may be known with near-certainty (in the case of historical or near-historical migrations) or it may be very uncertain (in the case of deep prehistory).
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.
Speaker typesWithin the linguistic study of endangered languages, sociolinguists distinguish between different speaker types based on the type of competence they have acquired of the endangered language. Often when a community is gradually shifting away from an endangered language to a majority language, not all speakers acquire full linguistic competence; instead, speakers have varying degrees and types of competence depending on their exposure to the minority language in their upbringing.
Koiné languageIn linguistics, a koiné language, koiné dialect, or simply koiné (Ancient Greek κοινή, "common [language]") is a standard or common language or dialect that has arisen as a result of the contact, mixing, and often simplification of two or more mutually intelligible varieties of the same language. As speakers already understood one another before the advent of the koiné, the process of koineization is not as drastic as pidginization and creolization.
CatalansCatalans (Catalan, French and Occitan: catalans; catalanes, Italian: catalani, cadelanos) are a Romance ethnic group native to Catalonia, who speak Catalan. The current official category of "Catalans" is that of the citizens of Catalonia, an autonomous community in Spain and the inhabitants of the Roussillon historical region in southern France, today the Pyrénées Orientales department, also called Northern Catalonia and Pays Catalan in French.
Sardinian languageSardinian or Sard (sardu ˈsaɾdu, limba sarda ˈlimba ˈzaɾda or lìngua sarda ˈliŋɡwa ˈzaɾda) is a Romance language spoken by the Sardinians on the Western Mediterranean island of Sardinia. Many Romance linguists consider it the language that, together with Italian, is the closest to Latin among all its genealogical descendants. However, it has also incorporated elements of a Pre-Latin (mostly Paleo-Sardinian and, to a much lesser degree, Punic) substratum, as well as a Byzantine Greek, Catalan, Castilian, and Italian superstratum.
Language attritionLanguage attrition is the process of losing a native or first language. This process is generally caused by both isolation from speakers of the first language ("L1") and the acquisition and use of a second language ("L2"), which interferes with the correct production and comprehension of the first. Such interference from a second language is probably experienced to some extent by all bilinguals, but is most evident among speakers for whom a language other than their first has started to play an important, if not dominant, role in everyday life; these speakers are more likely to experience language attrition.
Minoritized languageIn sociolinguistics, a minoritized language is a language that is marginalized, persecuted, or banned. Language minoritization stems from the tendency of large nations to establish a common language for commerce and government, or to establish homogeneity for ideological reasons. Minoritized languages are typically restricted to a smaller range of language domains than dominant languages, and frequently one-way bilingualism develops when speakers of minoritized languages learn the dominant language, but not vice versa.
AcculturationAcculturation is a process of social, psychological, and cultural change that stems from the balancing of two cultures while adapting to the prevailing culture of the society. Acculturation is a process in which an individual adopts, acquires and adjusts to a new cultural environment as a result of being placed into a new culture, or when another culture is brought to someone. Individuals of a differing culture try to incorporate themselves into the new more prevalent culture by participating in aspects of the more prevalent culture, such as their traditions, but still hold onto their original cultural values and traditions.
