The word Tagalog derived from tagailog, from tagá- meaning "native of" and ílog meaning "river." Thus, it means "river dweller." Very little is known about the history of the language. However, according to linguists such as Dr. David Zorc and Dr. Robert Blust, the Tagalogs originated, along with their Central Philippine cousins, from Northeastern Mindanao or Eastern Visayas.[5][6]
The first written record of Tagalog is in the Laguna Copperplate Inscription, written in the year 900 and uses fragments of the language along with Sanskrit, Malay, and Javanese. Meanwhile, the first known book to be written in Tagalog is the Doctrina Cristiana (Christian Doctrine) of 1593. It was written in Spanish and two versions of Tagalog; one written in the Baybayin script and the other in the Latin alphabet. Throughout the 333 years of Spanish occupation, there were grammar and dictionaries written by Spanish clergymen such as Vocabulario de la Lengua Tagala by Pedro de San Buenaventura (Pila, Laguna, 1613), Vocabulario de la lengua tagala (1835) and Arte de la lengua tagala y manual tagalog para la administración de los Santos Sacramentos (1850). Poet Francisco Baltazar (1788–1862) is regarded as the foremost Tagalog writer. His most famous work is the early 19th-century Florante at Laura.
In 1937, Tagalog was selected as the basis of the national language of the Philippines by the National Language Institute. In 1939, Manuel L. Quezon named the national language "Wikang Pambansâ" ("National Language").[7] Twenty years later, in 1959, it was renamed by then Secretary of Education, José Romero, as Pilipino to give it a national rather than ethnic label and connotation. The changing of the name did not, however, result in acceptance among non-Tagalogs, especially Cebuanos who had not accepted the selection.[8].
