Tagalog (pronunciation: [tɐˈgaːlog]) is one of the major languages of the Republic of the Philippines. It is the largest of the Philippine languages in terms of the number of speakers.
Tagalog, as its standardized counterpart, Filipino, is the principal language of the national media in the Philippines. It is the primary language of public education. It is, along with English, a co-official language and the sole national language. Tagalog is widely used as a lingua franca throughout the country, and in overseas Filipino communities. However, while Tagalog may be prevalent in those fields, English, to varying degrees of fluency, is more prevalent in the fields of government and business.
