Peruvian Sign Language is the deaf sign language of Peru. It is used primarily outside the classroom.
Classification
Wittmann (1991)[1] posits that ESL is a language isolate (a 'prototype' sign language), though one developed through stimulus diffusion from an existing sign language, likely French Sign Language.

^a Sign-language names reflect the region of origin. Natural sign languages are not related to the spoken language used in the same region. For example, French Sign Language originated in France, but is not related to French. Conversely, ASL and BSL both originated in English-speaking countries but are not related to each other; ASL however is related to French Sign Language.
^b Denotes the number (if known) of languages within the family. No further information is given on these languages.
