Gaddang language
The Gaddang language (also Cagayan) is spoken by up to 30,000 speakers (the Gaddang people) in the Philippines, particularly along the Magat and upper Cagayan rivers in the Region II provinces of Nueva Vizcaya and Isabela and by overseas migrants to countries in Asia, Australia, Canada, Europe, in the Middle East, United Kingdom and the United States. Most Gaddang speakers also speak Ilocano, the lingua franca of Northern Luzon, as well as Tagalog and English.
