Lyons Sign Language is a sign language of the Lyons region of France that has a long history. It is not intelligible with and is apparently not related to French Sign Language, which developed in Paris. The number of current speakers is not attested, and it is not even known if it is still spoken.[2]


Wittmann (1991)[3] 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.
