American Sign Language (ASL) is a natural language that serves as the predominant sign language of Deaf communities in the United States of America and most of Anglophone Canada. ASL is a complete and organized visual language that is expressed by employing both manual and nonmanual features. Besides North America, dialects of ASL and ASL-based creoles are used in many countries around the world, including much of West Africa and parts of Southeast Asia. ASL is also widely learned as a second language, serving as a lingua franca. ASL is most closely related to French Sign Language (LSF). It has been proposed that ASL is a creole language of LSF, although ASL shows features atypical of creole languages, such as agglutinative morphology.
Sign languages are languages that use the visual-manual modality to convey meaning, instead of spoken words. Sign languages are expressed through manual articulation in combination with non-manual markers. Sign languages are full-fledged natural languages with their own grammar and lexicon. Sign languages are not universal and are usually not mutually intelligible, although there are also similarities among different sign languages.
International Sign (IS) is a pidgin sign language which is used in a variety of different contexts, particularly at international meetings such as the World Federation of the Deaf (WFD) congress, in some European Union settings, and at some UN conferences, at events such as the Deaflympics, the Miss & Mister Deaf World, and Eurovision, and informally when travelling and socialising.
Auslan is the majority sign language of the Australian Deaf community. The term Auslan is a portmanteau of "Australian Sign Language", coined by Trevor Johnston in the 1980s, although the language itself is much older. Auslan is related to British Sign Language (BSL) and New Zealand Sign Language (NZSL); the three have descended from the same parent language, and together comprise the BANZSL language family. Auslan has also been influenced by Irish Sign Language (ISL) and more recently has borrowed signs from American Sign Language (ASL).
Deaf culture is the set of social beliefs, behaviors, art, literary traditions, history, values, and shared institutions of communities that are influenced by deafness and which use sign languages as the main means of communication. When used as a cultural label especially within the culture, the word deaf is often written with a capital D and referred to as "big D Deaf" in speech and sign. When used as a label for the audiological condition, it is written with a lower case d. Carl G. Croneberg coined the term "Deaf Culture" and he was the first to discuss analogies between Deaf and hearing cultures in his appendices C/D of the 1965 Dictionary of American Sign Language.
Signing Exact English is a system of manual communication that strives to be an exact representation of English vocabulary and grammar. It is one of a number of such systems in use in English-speaking countries. It is related to Seeing Essential English (SEE-I), a manual sign system created in 1945, based on the morphemes of English words. SEE-II models much of its sign vocabulary from American Sign Language (ASL), but modifies the handshapes used in ASL in order to use the handshape of the first letter of the corresponding English word.
Adamorobe Sign Language or Adasl is a village sign language used in Adamorobe, an Akan village in eastern Ghana. It is used by about 30 deaf and 1370 hearing people (2003).
Louis Laurent Marie Clerc was a French teacher called "The Apostle of the Deaf in America" and was regarded as the most renowned deaf person in American Deaf History. He was taught by Abbé Sicard and deaf educator Jean Massieu, at the Institution Nationale des Sourds-Muets in Paris. With Thomas Hopkins Gallaudet, he co-founded the first school for the deaf in North America, the Asylum for the Education and Instruction of the Deaf and Dumb, on April 15, 1817, in the old Bennet's City Hotel, Hartford, Connecticut. The school was subsequently renamed the American School for the Deaf and in 1821 moved to 139 Main Street, West Hartford. The school remains the oldest existing school for the deaf in North America.
Japanese Sign Language, also known by the acronym JSL, is the dominant sign language in Japan and is a complete natural language, distinct from but influenced by the spoken Japanese language.
Indo-Pakistani Sign Language (IPSL) is the predominant sign language in the subcontinent of South Asia, used by at least 15 million deaf signers. As with many sign languages, it is difficult to estimate numbers with any certainty, as the Census of India does not list sign languages and most studies have focused on the north and urban areas. As of 2021, it is the most used sign language in the world, and Ethnologue ranks it as the 151st most "spoken" language in the world.
Mokolo is the departmental capital and largest city of the Mayo-Tsanaga department, in the Far North Province of Cameroon. It is the fourth largest city in the Far North Province, after Maroua, Yagoua, and Kousséri. It is located in the Mandara Mountains that run along the Cameroonian-Nigerian border.
Brazilian Sign Language is the sign language used by deaf communities of urban Brazil. It is also known in short as Libras and variously abbreviated as LSB, LGB or LSCB.
Kata Kolok, also known as Benkala Sign Language and Balinese Sign Language, is a village sign language which is indigenous to two neighbouring villages in northern Bali, Indonesia. The main village, Bengkala, has had high incidences of deafness for over seven generations. Notwithstanding the biological time depth of the recessive mutation that causes deafness, the first substantial cohort of deaf signers did not occur until five generations ago, and this event marks the emergence of Kata Kolok. The sign language has been acquired by at least five generations of deaf, native signers and features in all aspects of village life, including political, professional, educational, and religious settings.
Bilingual–Bicultural or Bi-Bi deaf education programs use sign language as the native, or first, language of Deaf children. In the United States, for example, Bi-Bi proponents claim that American Sign Language (ASL) should be the natural first language for deaf children in the United States, although the majority of deaf and hard of hearing being born to hearing parents. In this same vein, the spoken or written language used by the majority of the population is viewed as a secondary language to be acquired either after or at the same time as the native language.
Korean Sign Language or KSL is a sign language used for deaf communities of South Korea under the North-South Korean border. It is often referred to simply as 수화; 手話; suhwa, which means signing in general.
The Romanian Sign Language is the sign language used by deaf people in Romania. In Romania, the first organization dedicated to people with hearing impairments was the Romanian Society of the Deaf-Mute, established on 9 November 1919. It was continued by the Romanian Association of the Deaf-Mute (1952), and the National Association of the Deaf from Romania.
A deaf-community or urban sign language is a sign language that emerges when deaf people who do not have a common language come together and form a community. This may be a formal situation, such as the establishment of a school for deaf students, or informal, such as migration to cities for employment and the subsequent gathering of deaf people for social purposes. An example of the first is Nicaraguan Sign Language, which emerged when deaf children in Nicaragua were brought together for the first time, and received only oral education; of the latter, Bamako Sign Language, which emerged among the tea circles of the uneducated deaf in the capital of Mali. Nicaraguan SL is now a language of instruction and is recognized as the national sign language; Bamako SL is not, and is threatened by the use of American Sign Language in schools for the deaf.
The Arab sign-language family is a family of sign languages spread across the Arab Middle East. Its extent is not yet known, because only some of the sign languages in the region have been compared.
Eritrean Sign Language (EriSL) is a sign language widely used in Eritrea. It developed out of the Swedish and Finnish Sign Languages, that were introduced by Swedish and Finnish Christian missionaries in 1955, containing a certain amount of local Eritrean signs and having ASL-based Sudanese influences. According to Moges 2011, 70% of the EriSL and Finnish signs are identical. Since 2005, the Eritrean National Association of the Deaf has made linguistic purification attempts to replace Swedish and Finnish signs from the EriSL lexicon by 'Eritrean' ones in an effort to create a more distinct, "indigenous" language. This process is referred to as 'demissionization'.
A nonmanual feature, also sometimes called nonmanual signal or sign language expression, are the features of signed languages that do not use the hands. Nonmanual features are gramaticised and a necessary component in many signs, in the same way that manual features are. Nonmanual features serve a similar function to intonation in spoken languages.
