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.
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.
Finnish Sign Language is the sign language most commonly used in Finland. There are 3,000 (2012 estimate) Finnish deaf who have Finnish Sign Language as a first language. As the Finnish system records users by their written language, not their spoken alone, nearly all deaf people who sign are assigned this way and may be subsumed into the overall Finnish language figures. Historically the aim was oralism, whereby deaf people were taught to speak oral Finnish, even if they could not hear it; thus older people are recorded under these figures. In 2014, only 500 people registered Finnish Sign Language as their first language. There are several sign languages that come under this label; FSL for those that can see; Signed Finnish, which does not follow the same grammatical rules, and a version for those who are blind and deaf. Thus, there are around 8,000 people that use a Finnish Sign Language linguistically. Many estimates say 5,000, but these are exaggerations derived from the 14,000 deaf people in Finland. Finnish Sign Language is derived from Swedish Sign Language, which is a different language from Finnish Swedish Sign Language, from which it began to separate as an independent language in the middle of the 19th century.
Cued speech is a visual system of communication used with and among deaf or hard-of-hearing people. It is a phonemic-based system which makes traditionally spoken languages accessible by using a small number of handshapes, known as cues, in different locations near the mouth to convey spoken language in a visual format. The National Cued Speech Association defines cued speech as "a visual mode of communication that uses hand shapes and placements in combination with the mouth movements and speech to make the phonemes of spoken language look different from each other." It adds information about the phonology of the word that is not visible on the lips. This allows people with hearing or language difficulties to visually access the fundamental properties of language. It is now used with people with a variety of language, speech, communication, and learning needs. It is not a sign language such as American Sign Language (ASL), which is a separate language from English. Cued speech is considered a communication modality but can be used as a strategy to support auditory rehabilitation, speech articulation, and literacy development.
Deafblindness is the condition of little or no useful hearing and little or no useful sight. Different degrees of vision loss and auditory loss occur within each individual. Because of this inherent diversity, each deafblind individual's needs regarding lifestyle, communication, education, and work need to be addressed based on their degree of dual-modality deprivation, to improve their ability to live independently. In 1994, an estimated 35,000–40,000 United States residents were medically deafblind. Laura Bridgman was the first American deafblind person known to become well educated. Helen Keller was a well-known example of an educated deafblind individual. To further her lifelong mission to help the deafblind community to expand its horizons and gain opportunities, the Helen Keller National Center for Deaf-Blind Youths and Adults, with a residential training program in Sands Point, New York, was established in 1967 by an act of Congress.
Several manual alphabets in use around the world employ two hands to represent some or all of the letters of an alphabet, usually as a part of a deaf sign language. Two-handed alphabets are less widespread than one-handed manual alphabets. They may be used to represent the Latin alphabet or the Cyrillic alphabet.
Tactile signing is a common means of communication used by people with deafblindness. It is based on a sign language or another system of manual communication.
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.
Icelandic Sign Language is the sign language of the deaf community in Iceland. It is based on Danish Sign Language; until 1910, deaf Icelandic people were sent to school in Denmark, but the languages have diverged since then. It is officially recognized by the state and regulated by a national committee.
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 2024, it is the most used sign language in the world, and Ethnologue ranks it as the 149th most "spoken" language in the world.
Turkish Sign Language is the language used by the deaf community in Turkey. As with other sign languages, TİD has a unique grammar that is different from the oral languages used in the region.
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.
Polish Sign Language is the language of the deaf community in Poland. Polish Sign Language uses a distinctive one-handed manual alphabet based on the alphabet used in Old French Sign Language and therefore appears to be related to French Sign Language. It may also have common features with Russian Sign Language and German Sign Language, which is related to the history of Poland during the Partitions, when Russification and Germanization significantly influenced the Polish language, and may also have borrowings from the sign language used in the Austrian partition. Its lexicon and grammar are distinct from the Polish language, although there is a manually coded version of Polish known as System Językowo-Migowy, which is often used by interpreters on television and by teachers in schools.
Italian Sign Language is the visual language used by deaf people in Italy. Deep analysis of it began in the 1980s, along the lines of William Stokoe's research on American Sign Language in the 1960s. Until the beginning of the 21st century, most studies of Italian Sign Language dealt with its vocabulary. According to the European Union for the Deaf, the majority of the 60,000–90,000 Deaf people in Italy use LIS.
Maritime Sign Language is a sign language used in Canada's Atlantic provinces.
The deaf sign language of the nations of the former Yugoslavia, known variously as Croatian Sign Language, Kosovar Sign Language, Serbian Sign Language, Bosnian Sign Language, Macedonian Sign Language, Slovenian Sign Language, or Yugoslav Sign Language (YSL), started off when children were sent to schools for the deaf in Austro-Hungary in the early 19th century. The first two local schools opened in 1840 in Slovenia and in 1885 in Croatia.
