Language isolates are languages that cannot be classified into larger language families.

. It is a natural language with no demonstrable genealogical (or "genetic") relationships—one that has not been demonstrated to descend from an ancestor common with any other language. One explanation for the existence of language isolates is that they might be the last remaining branch of a larger language family. The language possibly had relatives in the past which have since disappeared without being documented. Another explanation for language isolates is that they developed in isolation from other languages. This explanation mostly applies to sign languages that have arisen independently of other spoken or signed languages. Some languages once seen as isolates may be reclassified as small families if some of their dialects are judged to be sufficiently different from the standard to be seen as different languages. Examples include

Genetic or genealogical relationships

A language isolate is a language that has no demonstrable genealogical (or "genetic") relationship to any other known language. It is not the descendant of any ancestral language which has other known descendants or

daughter language In historical linguistics, a daughter language, also known as descendant language, is a language descended from another language, its mother language, through a process of genetic descent. If more than one language has developed from the same pro ...

A "genetic relationship" is a connection between languages, like similarities in vocabulary or grammar, that can be attributed to a common ancestral language that diverged into multiple daughter languages or branches. This is what makes up a

can be safely classified as isolates, as the languages are well enough documented that, if modern relatives existed, they would be recognizably related. A language thought to be an isolate may turn out to be related to other languages once enough material is recovered, but this is unlikely for extinct languages whose written records have not been preserved. Many extinct languages are very poorly attested which may lead to them being considered

Sign language isolates

A number of

, a well documented case of what has happened in schools for the deaf in many countries. In Tanzania, for example, there are seven schools for the deaf, each with its own

with no known connection to any other language. Sign languages have also developed outside schools, in communities with high incidences of deafness, such as

. These and more are all presumed isolates or small local families, because many deaf communities are made up of people whose hearing parents do not use sign language, and have manifestly, as shown by the language itself, not borrowed their sign language from other deaf communities during the recorded history of these languages.

. "Endangered" languages are either acquired irregularly or spoken only by older generations. "Moribund" languages have only a few remaining native speakers, with no new acquisition, highly restricted use, and near-universal multilingualism. "Extinct" languages have no native speakers, but are sufficiently documented to be classified as isolates.
