Lyons Sign Language is an old sign language of France. It is not intelligible with and apparently not related to French Sign Language, which developed in Paris. The number of current speakers is not attested.


Wittmann (1991)[2] posits that LSL is a language isolate (a 'prototype' sign language).

Wittmann further suspects that LSL gave rise to Belgian Sign Language, of which today the two dialects, Flemish Sign Language and French Belgian Sign Language, are treated separately.
