Filipino and English are the official languages of the country. Filipino is a standardized version of Tagalog, spoken mainly in Metro Manila. Both Filipino and English are used in government, education, print, broadcast media, and business, with third local languages often being used at the same time. The Philippine constitution provides for the promotion of Spanish and Arabic on a voluntary and optional basis. Spanish, which was widely used as a lingua franca in the late nineteenth century, has since declined greatly in use, although Spanish loanwords are still present today in Philippine languages, while Arabic is mainly taught in Islamic schools in Mindanao.
