Costa Rican Sign Language, also known New Costa Rican Sign Language or Modern Costa Rican Sign Language, is the national sign language of Costa Rica's Deaf community. It is used primarily by people born after 1960, and is about 60% cognate with American Sign Language (Woodward 1991, 1992). It is unrelated to two known village sign languages of Costa Rica, Bribri Sign Language and Brunca Sign Language.
