[edit] Language families

In the following, each "bulleted" item is a known or suspected language family. The geographic headings over them are meant solely as a tool for grouping families into collections more comprehensible than an unstructured list of the dozen or two of independent families. Geographic relationship is convenient for that purpose, but these headings are not a suggestion of any "super-families" phylogenetically relating the families named.

[edit] Unclassified languages

Languages are considered unclassified either because, for one reason or another, little effort has been made to compare them with other languages, or, more commonly, because they are too poorly documented to permit reliable classification. Most such languages are extinct and most likely will never be known well enough to classify.

[edit] Sign languages

See also: List of sign languages

Although deaf sign languages have emerged naturally in deaf communities alongside or among spoken languages, they are unrelated to spoken languages and have different grammatical structures at their core. A group of sign "languages" known as manually coded languages are more properly understood as signed modes of spoken languages, and therefore belong to the language family of the spoken language. One example of such a signed language is Warlpiri Sign Language, which belongs to the family of Ngarrkic languages.

There has been very little historical linguistic research on sign languages, and few attempts to determine genetic relationships between sign languages, other than simple comparison of lexical data and some discussion about whether certain sign languages are dialects of a language or languages of a family. Languages may be spread through migration, through the establishment of deaf schools (often by foreign-trained educators), or due to political domination.

Language contact is common, making clear family classifications difficult — it is often unclear whether lexical similarity is due to borrowing or a common parent language. Contact occurs between sign languages, between signed and spoken languages (Contact Sign), and between sign languages and gestural systems used by the broader community. One author has speculated that Adamorobe Sign Language may be related to the "gestural trade jargon used in the markets throughout West Africa", in vocabulary and areal features including prosody and phonetics.

• Auslan, NZSL and BSL are usually considered to belong to a language family known as BANZSL.

• Japanese Sign Language, Taiwanese Sign Language and Korean Sign Language are thought to be members of a Japanese Sign Language family.

• There are a number of sign languages that emerged from French Sign Language (LSF), or were the result of language contact between local community sign languages and LSF. These include: French Sign Language, Quebec Sign Language, American Sign Language, Irish Sign Language, Russian Sign Language, Dutch Sign Language, Flemish Sign Language, Belgian-French Sign Language, Spanish Sign Language, Mexican Sign Language and others.

• A subset of this group includes languages that have been heavily influenced by American Sign Language (ASL), or are regional varieties of ASL. Bolivian Sign Language is sometimes considered a dialect of ASL. Thai Sign Language is a mixed language derived from ASL and the native sign languages of Bangkok and Chiang Mai, and may be considered part of the ASL family. Others possibly influenced by ASL include Ugandan Sign Language, Kenyan Sign Language, Philippine Sign Language and Malaysian Sign Language.

• Anecdotal evidence suggests that Finnish Sign Language, Swedish Sign Language and Norwegian Sign Language belong to a Scandinavian Sign Language family.

• According to a SIL report, sign languages of Russia, Moldova and Ukraine share a high degree of lexical similarity and may be dialects of one language, or distinct related languages. The same report suggested a "cluster" of sign languages centered around Czech Sign Language, Hungarian Sign Language and Slovakian Sign Language. This group may also include Romanian, Bulgarian, and Polish sign languages.

• Known isolates include Nicaraguan Sign Language, Al-Sayyid Bedouin Sign Language, and Providence Island Sign Language.

• Sign languages of Jordan, Lebanon, Syria, Palestine, and Iraq (and possibly Saudi Arabia) may be part of a sprachbund, or may be one dialect of a larger Eastern Arabic Sign Language.
