Ethnologue: Languages of the World 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.
A language family is a group of languages related through descent from a common ancestral language or parental language, called the proto-language of that family. The term family is a metaphor borrowed from biology—with the tree model used in historical linguistics analogous to a family tree, or to phylogenetic trees of species used in evolutionary taxonomy. Linguists thus describe the daughter languages within a language family as being genetically related. The divergence of a proto-language into daughter languages typically occurs through geographical separation, with different regional dialects of the proto-language spoken by different speech communities undergoing different language changes and thus becoming distinct languages from each other.
A creole language, or simply creole, is a stable natural language that develops from the process of different languages simplifying and mixing into a new form, and then that form expanding and elaborating into a full-fledged language with native speakers, all within a fairly brief period. While the concept is similar to that of a mixed or hybrid language, creoles are often characterized by a tendency to systematize their inherited grammar. Like any language, creoles are characterized by a consistent system of grammar, possess large stable vocabularies, and are acquired by children as their native language. These three features distinguish a creole language from a pidgin. Creolistics, or creology, is the study of creole languages and, as such, is a subfield of linguistics. Someone who engages in this study is called a creolist.
A lingua franca, also known as a bridge language, common language, trade language, auxiliary language, vehicular language, or link language, is a language systematically used to make communication possible between groups of people who do not share a native language or dialect, particularly when it is a third language that is distinct from both of the speakers' native languages.
Asia is home to hundreds of languages comprising several families and some unrelated isolates. The most spoken language families on the continent include Austroasiatic, Austronesian, Japonic, Dravidian, Indo-European, Afroasiatic, Turkic, Sino-Tibetan, Kra–Dai and Koreanic. Many languages of Asia, such as Chinese, Sanskrit, Arabic, Tamil or Telugu, have a long history as a written language.
ISO 639 is a standard by the International Organization for Standardization (ISO) concerned with representation of languages and language groups. It currently consists of four sets of code, named after each part which formerly described respective set ; a part 6 was published but withdrawn. It was first approved in 1967 as a single-part ISO Recommendation, ISO/R 639, superseded in 2002 by part 1 of the new series, ISO 639-1, followed by additional parts. All existing parts of the series were consolidated into a single standard in 2023, largely based on the text of ISO 639-4.
An extinct language is a language with no living descendants that no longer has any first-language or second-language speakers. In contrast, a dead language is a language that no longer has any first-language speakers, but does have second-language speakers or is used fluently in written form, such as Latin. A dormant language is a dead language that still serves as a symbol of ethnic identity to an ethnic group; these languages are often undergoing a process of revitalisation. Languages that have first-language speakers are known as modern or living languages to contrast them with dead languages, especially in educational contexts.
Pakistan is a multilingual country with over 70 languages spoken as first languages. The majority of Pakistan's languages belong to the Indo-Iranian group of the Indo-European language family. Urdu is the national language and the lingua franca of Pakistan, and while sharing official status with English, it is the preferred and dominant language used for inter-communication between different ethnic groups. Numerous regional languages are spoken as first languages by Pakistan's various ethnolinguistic groups. Languages with more than a million speakers each include Punjabi, Pashto, Sindhi, Saraiki, Urdu, Balochi, Hindko and Brahui. There are approximately 60 local languages with fewer than a million speakers.
ISO 639-2:1998, Codes for the representation of names of languages — Part 2: Alpha-3 code, is the second part of the ISO 639 standard, which lists codes for the representation of the names of languages. The three-letter codes given for each language in this part of the standard are referred to as "Alpha-3" codes. There are 487 entries in the list of ISO 639-2 codes.
Portuguese creoles are creole languages which have Portuguese as their substantial lexifier. The most widely-spoken creoles influenced by Portuguese are Cape Verdean Creole, Guinea-Bissau Creole and Papiamento.
Language 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. 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.
Hawaiʻi Sign Language or Hawaiian Sign Language, also known as Hoailona ʻŌlelo, Old Hawaiʻi Sign Language and Hawaiʻi Pidgin Sign Language, is an indigenous sign language native to Hawaiʻi. Historical records document its presence on the islands as early as the 1820s, but HSL was not formally recognized by linguists until 2013.
A mixed language, also referred to as a hybrid language, contact language, or fusion language, is a language that arises among a bilingual group combining aspects of two or more languages but not clearly deriving primarily from any single language. It differs from a creole or pidgin language in that, whereas creoles/pidgins arise where speakers of many languages acquire a common language, a mixed language typically arises in a population that is fluent in both of the source languages.
ISO 639-3:2007, Codes for the representation of names of languages – Part 3: Alpha-3 code for comprehensive coverage of languages, is an international standard for language codes in the ISO 639 series. It defines three-letter codes for identifying languages. The standard was published by International Organization for Standardization (ISO) on 1 February 2007.
The languages of the Caribbean reflect the region's diverse history and culture. There are six official languages spoken in the Caribbean:
Spurious languages are languages that have been reported as existing in reputable works, while other research has reported that the language in question did not exist. Some spurious languages have been proven to not exist. Others have very little evidence supporting their existence, and have been dismissed in later scholarship. Others still are of uncertain existence due to limited research.
Glottolog is an open-access online bibliographic database of the world's languages. In addition to listing linguistic materials describing individual languages, the database also contains the most up-to-date language affiliations based on the work of expert linguists.
