Filipino (English: FIL-ə-PEE-noh; Wikang Filipino, [ˈwikɐŋ filiˈpino̞]) is the national language (Wikang pambansa / Pambansang wika) of the Philippines, the main lingua franca (Karaniwang wika), and one of the two official languages (Wikang opisyal/Opisyal na wika) of the country, along with English. It is only a de facto and not a de jure standardized form of the Tagalog language, as spoken and written in Metro Manila, the National Capital Region, and in other urban centers of the archipelago. The 1987 Constitution mandates that Filipino be further enriched and developed by the other languages of the Philippines.

Filipino, like other Austronesian languages, commonly uses verb-subject-object order, but can also use subject-verb-object order. Filipino follows the trigger system of morphosyntactic alignment that is common among Philippine languages. It has head-initial directionality. It is an agglutinative language but can also display inflection. It is not a tonal language and can be considered a pitch-accent language and a syllable-timed language. It has nine basic parts of speech.
