Igorots.—With the name Ygolot the first chroniclers characterized the warlike heathen who now inhabit Benguet, therefore the pure Igorots. Later, the name extended to all the head-hunters of northern Luzon; still later it was made to cover the Philippine islanders collectively, and to-day the title is so comprehensive that the name Igorot is synonymous with wild. According to Hans Meyer, the name applies only to the Igorots of Lepanto and Benguet, who speak the dialects Inibaloi, Cancanai, Cataoan, and a fourth (Suflin?), that of the Berpe Data.
Variant: Ygolot, Ygulut.
