An excerpt from the article 24 facts about Philippines

Filipino is an adapted form of Tagalog (Tagalog - one of the most important languages in the Philippines), enriched with vocabulary from other Filipino languages. It is the native language of much of the population in the central regions of the Philippines, with some 25 million people using it.

The Constitution also designates regional languages such as Bikol, Cebuano, Ilocano, Hiligainon, Pampango, Pangasinense, Tagalog, and Samareño as auxiliary official languages. Spanish (there are currently about 400.000 Spanish speakers) and Arabic are also used voluntarily.
