Tijuana Sign Language is a deaf sign language of Mexico, but one unintelligible with, and apparently unrelated to, Mexican Sign Language.


Wittmann (1991)[1] posits that TSL is a language isolate (a 'prototype' sign language), though one developed through stimulus diffusion from an existing sign language, likely of the French Sign Language family.
