American Sign Language (ASL) is a natural language that serves as the predominant sign language of deaf communities in the United States 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.
Fingerspelling is the representation of the letters of a writing system, and sometimes numeral systems, using only the hands. These manual alphabets have often been used in deaf education and have subsequently been adopted as a distinct part of a number of sign languages. There are about forty manual alphabets around the world. Historically, manual alphabets have had a number of additional applications—including use as ciphers, as mnemonics and in silent religious settings.
In linguistics and specifically phonology, a phoneme is any set of similar phones that is perceptually regarded by the speakers of a language as a single distinct unit, a single basic sound, which helps distinguish one word from another.
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 similarities among different sign languages.
Sutton SignWriting, or simply SignWriting, is a system of writing sign languages. It is highly featural and visually iconic, both in the shapes of the characters, which are abstract pictures of the hands, face, and body, and in their spatial arrangement on the page, which does not follow a sequential order like the letters that make up written English words. It was developed in 1974 by Valerie Sutton, a dancer who had, two years earlier, developed DanceWriting. Some newer standardized forms are known as the International Sign Writing Alphabet (ISWA).
Auslan (Australian Sign Language) is the sign language used by the majority of the Australian Deaf community. 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. As with other sign languages, Auslan's grammar and vocabulary is quite different from spoken English. Its origin cannot be attributed to any individual; rather, it is a natural language that emerged spontaneously and has changed over time.
Signing Exact English is a system of manual communication that strives to be an exact representation of English language 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.
The American Manual Alphabet (AMA) is a manual alphabet that augments the vocabulary of American Sign Language.
Manually Coded English (MCE) is an umbrella term referring to a number of invented manual codes intended to visually represent the exact grammar and morphology of spoken English. Different codes of MCE vary in the levels of adherence to spoken English grammar, morphology, and syntax. MCE is typically used in conjunction with direct spoken English.
The Japanese Sign Language syllabary is a system of manual kana used as part of Japanese Sign Language (JSL). It is a signary of 45 signs and 4 diacritics representing the phonetic syllables of the Japanese language. Signs are distinguished both in the direction they point, and in whether the palm faces the viewer or the signer. For example, the manual syllables na, ni, ha are all made with the first two fingers of the hand extended straight, but for na the fingers point down, for ni across the body, and for ha toward the viewer. The signs for te and ho are both an open flat hand, but in te the palm faces the viewer, and in ho it faces away.
Stokoe notation is the first phonemic script used for sign languages. It was created by William Stokoe for American Sign Language (ASL), with Latin letters and numerals used for the shapes they have in fingerspelling, and iconic glyphs to transcribe the position, movement, and orientation of the hands. It was first published as the organizing principle of Sign Language Structure: An Outline of the Visual Communication Systems of the American Deaf (1960), and later also used in A Dictionary of American Sign Language on Linguistic Principles, by Stokoe, Casterline, and Croneberg (1965). In the 1965 dictionary, signs are themselves arranged alphabetically, according to their Stokoe transcription, rather than being ordered by their English glosses as in other sign-language dictionaries. This made it the only ASL dictionary where the reader could look up a sign without first knowing how to translate it into English. The Stokoe notation was later adapted to British Sign Language (BSL) in Kyle et al. (1985) and to Australian Aboriginal sign languages in Kendon (1988). In each case the researchers modified the alphabet to accommodate phonemes not found in ASL.
In Deaf culture and sign language, a sign name is a special sign that is used to uniquely identify a person.
Manually coded languages (MCLs) are a family of gestural communication methods which include gestural spelling as well as constructed languages which directly interpolate the grammar and syntax of oral languages in a gestural-visual form—that is, signed versions of oral languages. Unlike the sign languages that have evolved naturally in deaf communities, these manual codes are the conscious invention of deaf and hearing educators, and as such lack the distinct spatial structures present in native deaf sign languages. MCLs mostly follow the grammar of the oral language—or, more precisely, of the written form of the oral language that they interpolate. They have been mainly used in deaf education in an effort to "represent English on the hands" and by sign language interpreters in K-12 schools, although they have had some influence on deaf sign languages where their implementation was widespread.
Chinese Sign Language is the official sign language of China. It is different from the Taiwanese Sign Language and is known in Taiwan as Wénfǎ Shǒuyǔ.
In sign languages, handshape, or dez, refers to the distinctive configurations that the hands take as they are used to form words. In Stokoe terminology it is known as the DEZ, an abbreviation of designator. Handshape is one of five components of a sign, along with location, orientation, movement, and nonmanual features. Different sign languages make use of different handshapes.
The grammar of American Sign Language (ASL) has rules just like any other sign language or spoken language. ASL grammar studies date back to William Stokoe in the 1960s. This sign language consists of parameters that determine many other grammar rules. Typical word structure in ASL conforms to the SVO/OSV and topic-comment form, supplemented by a noun-adjective order and time-sequenced ordering of clauses. ASL has large CP and DP syntax systems, and also doesn't contain many conjunctions like some other languages do.
Nepalese Sign Language or Nepali Sign Language (Nepali: नेपाली साङ्केतिक भाषा, romanized: Nēpālī Sāṅkētika Bhāṣā is the main sign language of Nepal. It is a partially standardized language based informally on the variety used in Kathmandu, with some input from varieties from Pokhara and elsewhere. As an indigenous sign language, it is not related to oral Nepali. The Nepali Constitution of 2015 specifically mentions the right to have education in Sign Language for the deaf. Likewise, the newly passed Disability Rights Act of 2072 BS defined language to include "spoken and sign languages and other forms of speechless language." in practice it is recognized by the Ministry of Education and the Ministry of Women, Children and Social Welfare, and is used in all schools for the deaf. In addition, there is legislation underway in Nepal which, in line with the UN Convention on the Rights of Persons with Disabilities which Nepal has ratified, should give Nepalese Sign Language equal status with the oral languages of the country.
In sign language, mouthing is the production of visual syllables with the mouth while signing. That is, signers sometimes say or mouth a word in a spoken language at the same time as producing the sign for it. Mouthing is one of the many ways in which the face and mouth is used while signing. Although not present in all sign languages, and not in all signers, where it does occur it may be an essential element of a sign, distinguishing signs which would otherwise be homophones; in other cases a sign may seem to be flat and incomplete without mouthing even if it is unambiguous. Other signs use a combination of mouth movements and hand movements to indicate the sign; for example, the ASL sign for NOT-YET includes a mouth gesture where the mouth is slightly open.
Sign languages such as American Sign Language (ASL) are characterized by phonological processes analogous to, yet dissimilar from, those of oral languages. Although there is a qualitative difference from oral languages in that sign-language phonemes are not based on sound, and are spatial in addition to being temporal, they fulfill the same role as phonemes in oral languages.
An Esperanto manual alphabet is included as part of the Signuno project for manually coded Esperanto. Signuno is based on the signs of International Sign, but adapted to the grammatical system of Esperanto.
