Gaddang, also Gadang or Ga’dang is derived from ga meaning heat or fire and dang meaning burn. This term means burned by heat. The name probably alludes to the skin color of gadding, a people found in Northern Nueva Vizcaya, especially Bayombong, Solano, and Bagabag on the Western bank of Magat River, and Santiago, Angadanan, Cauayan, and Reina Mercedes on the Cagayan River for Christianized groups; and western Isabela for non-Christianized communities (Philippine Almanac,1986)
The Gadang Literary materials of the Christian and non Christian Gaddabd include riddles, proverbs, poems, legends, and the epic of Biuag and Malana (Lumicao-Lora, 1984)
