nearly extinct
Campbell, Lyle and Lee, Nala Huiying and Okura, Eve and Simpson, Sean and Ueki, Kaori 2022
Original Costa Rican Sign Language (7006) = Critically Endangered (60 percent certain, based on the evidence available) ("Hasta donde sabemos, la variedad OLESCO, la lengua autóctona creada por las personas sordas en Costa Rica, ha venido retrocediendo desde hace varias décadas, sin que haya sido descrita ni documentada, de modo que se podría catalogar como en grave peligro." [As far as we know, Original Costa Rican Sign Language, the indigenous language created by deaf people in Costa Rica, has been declining for several decades, without being documented or described, such that it should be classified as very endangered.])
