Filipino is constitutionally designated as the national language of the Philippines and, along with English, one of two official languages. In 1959, the language became known as Pilipino in an effort to dissociate it from the Tagalog ethnic group. Later, the 1973 Constitution provided for a separate national language to replace Pilipino, a language which it termed Filipino. Filipino was simply Tagalog in syntax and grammar, with as yet no grammatical element or lexicon coming from Ilocano, Cebuano, Hiligaynon, or any of the other Philippine languages. Filipino is the formal name of Tagalog, or even a synonym of it. It is sometimes described as "Tagalog-based", part of a political fiction that the national language is based on an amalgam of Philippine languages rather than on Tagalog alone.
