Ecuadorian Sign Language
Ecuadorian Sign Language is the deaf sign language of Ecuador. Classification
Clark notes that Peruvian, Bolivian, Ecuadorian and Colombian sign languages "have significant lexical similarities to each other" and "contain a certain degree of lexical influence from ASL" as well, at least going by the forms in national dictionaries. Chilean and Argentinian share these traits, though to a lesser extent. References
