Cuyonon is a language spoken on the coast of Palawan, and the Cuyo Islands in the Philippines. Cuyonon had been the lingua franca (language used for communication) of the province of Palawan until recently when migration flow rapidly increased. 43% of the total population of Palawan during the late ‘80s spoke and used Cuyonon as a language. But later studies show a significant decrease in the number of Cuyonon speakers. The Cuyonon language is classified by the Summer Institute of Linguistics as belonging to the Central Philippine, West Bisayan, Kuyan subgroup. The biggest number of speakers lives in the Cuyo Group of Islands, which is located between Northern Palawan and Panay Island.
