Cuyonon is a regional Bisayan language spoken on the coast of Palawan and the Cuyo Islands in the Philippines.
[2] Cuyonon had been the lingua franca (language used for communication) of the province of Palawan until recently[when?]
Forty-three percent of the total population of Palawan during the late 1980s spoke and used Cuyonon as a language.
Later studies showed a significant decrease in the number of speakers due to an increase of Tagalog-speaking immigrants from Luzon.
The Cuyonon language is classified by the Summer Institute of Linguistics as belonging to the Central Philippine, Western Bisayan, Kuyan subgroup.
