Rufino José Cuervo Urisarri (Bogotá, Colombia), was a Colombian writer, linguist, and philologist. He studied Latin and Greek, but the main part of his work was dedicated to the study of the dialectal variations of Spanish spoken in Colombia. About this topic, he wrote his book Apuntaciones críticas sobre lenguaje bogotano (Critical Notes About Bogotan Language, 1867), which is still an important reference in the study of the American Spanish language.
