About Filipino
Filipino is the national language of the Philippines and, along with English, is an official language designated in the 1987 Philippine Constitution. Filipino is an Austronesian language that is based on existing native languages in the Philippines; the most significant influence is the Tagalog language. A large number of Spanish and English loanwords also exist in the vocabulary. The Filipino language remains in evolution, development, and further enrichment on the basis of existing languages of the Philippines and other languages. It is the first language of Filipinos living in Metro Manila and the second language of most Filipinos.

Sometimes the term "Filipino" is incorrectly used as the generic name for all the languages of the Philippines. Also, because of its similarity to the language on which it is based, it is still sometimes identified with Tagalog.
