In 2010, the US Census bureau reported (based on data collected in 2007) that in the United States it was the fourth most-spoken language at home with almost 1.5 million speakers, behind Spanish or Spanish Creole, French (including Patois, Cajun, Creole), and Chinese.Tagalog ranked as the third most spoken language in metropolitan statistical areas, behind Spanish and Chinese but ahead of French.After study and deliberation, the National Language Institute, a committee composed of seven members who represented various regions in the Philippines, chose Tagalog as the basis for the evolution and adoption of the national language of the Philippines. Quezon then, on December 30, 1937, proclaimed the selection of the Tagalog language to be used as the basis for the evolution and adoption of the national language of the Philippines.The 1973 constitution designated the Tagalog-based "Pilipino", along with English, as an official language and mandated the development and formal adoption of a common national language to be known as Filipino.Batangas Tagalog boasts the most distinctive accent in Tagalog compared to the more Hispanized northern accents of the language.
In addition, Tagalog is used as a second language across the Philippines. Without proper rendering support, you may see question marks, boxes, or other symbols instead of Unicode characters.The Tagalog language also boasts accentations unique to some parts of Tagalog-speaking regions.For example, in some parts of Manila, a strong pronunciation of i exists and vowel-switching of o and u exists so words like "gising" (to wake) is pronounced as "giseng" with a strong 'e' and the word "tagu-taguan" (hide-and-go-seek) is pronounced as "tago-tagoan" with a mild 'o'.It is related to other Philippine languages, such as the Bikol languages, Ilocano, the Visayan languages, Kapampangan, and Pangasinan, and more distantly to other Austronesian languages, such as the Formosan languages of Taiwan, Malay (Malaysian and Indonesian), Hawaiian, Māori, and Malagasy. Robert Blust speculate that the Tagalogs and other Central Philippine ethno-linguistic groups originated in Northeastern Mindanao or the Eastern Visayas.The word Tagalog is derived from the endonym taga-log ("river dweller"), composed of tagá- ("native of" or "from") and ilog ("river"). The first written record of Tagalog is the Laguna Copperplate Inscription, which dates to 900 CE and exhibits fragments of the language along with Sanskrit, Old Malay, Javanese and Old Tagalog.
