The name Philippines (Filipino: Pilipinas [pɪlɪˈpinɐs]; Spanish: Filipinas) derives from that of the 16th-century Spanish king Philip II, and is a truncated form of Philippine Islands. During the expedition of Ruy López de Villalobos to the region, the Spanish sailor Bernardo de la Torre bestowed the name Las Islas Filipinas on the islands of Leyte and Samar, in honor of the then Prince of Asturias (heir to the Spanish throne).[1][2] Despite the existence of other names, Filipinas ("Philippines") was eventually adopted as the name of the entire archipelago.
