Sechuran
Sechuran was a language isolate once spoken in Peru.
An isolate: no relationship to any other known language has been demonstrated.
The Sechura language, also known as Sec, is an extinct language spoken in the Department of Piura of Peru, near the port of Sechura. It appears to have become extinct by the beginning of the 20th century. The only documentation is that of an 1863 word list by Richard Spruce, as well as a word list by Bishop Martínez Compañón (1782–1790).
