San Juan Quiahije Chatino Sign Language (Spanish:Lengua de señas chatina de San Juan Quiahije, also known asCha'ya'[2]) is an emergingvillage sign language of the indigenousChatino villages ofSan Juan Quiahije andCieneguilla inOaxaca, Mexico, used by both the deaf and some of the hearing population.[3] It is apparently unrelated toMexican Sign Language. As of 2014, there is aNational Science Foundation-funded study and also aNational Institutes of Health-funded study of the development of this language.[4]
Non-signing hearing people in the village use various gestures for negation when speaking, and these are retained in Chatino Sign Language. The variability of these signs may be due to the small size of the deaf population in comparison to the number of hearing people who use them as co-speech gestures.[1]
