History

The word Tagalog is possibly derived from the endonym taga-ilog ("river dweller"), composed of tagá- ("native of" or "from") and ilog ("river"), or alternatively, taga-alog deriving from alog ("pool of water in the lowlands"; "rice or vegetable plantation"). Linguists such as David Zorc and Robert Blust speculate that the Tagalogs and other Central Philippine ethno-linguistic groups originated in Northeastern Mindanao or the Eastern Visayas.

Possible words of Old Tagalog origin are attested in the Laguna Copperplate Inscription from the tenth century, which is largely written in Old Malay. The first known complete book to be written in Tagalog is the Doctrina Christiana (Christian Doctrine), printed in 1593. The Doctrina was written in Spanish and two transcriptions of Tagalog; one in the ancient, then-current Baybayin script and the other in an early Spanish attempt at a Latin orthography for the language.

Throughout the 333 years of Spanish rule, various grammars and dictionaries were written by Spanish clergymen. In 1610, the Dominican priest Francisco Blancas de San José published the Arte y reglas de la lengua tagala (which was subsequently revised with two editions in 1752 and 1832) in Bataan. In 1613, the Franciscan priest Pedro de San Buenaventura published the first Tagalog dictionary, his Vocabulario de la lengua tagala in Pila, Laguna.

The first substantial dictionary of the Tagalog language was written by the Czech Jesuit missionary Pablo Clain in the beginning of the 18th century. Clain spoke Tagalog and used it actively in several of his books. He prepared the dictionary, which he later passed over to Francisco Jansens and José Hernandez. Further compilation of his substantial work was prepared by P. Juan de Noceda and P. Pedro de Sanlucar and published as Vocabulario de la lengua tagala in Manila in 1754 and then repeatedly reedited, with the last edition being in 2013 in Manila.

Among others, Arte de la lengua tagala y manual tagalog para la administración de los Santos Sacramentos (1850) in addition to early studies of the language.

The indigenous poet Francisco Balagtas (1788–1862) is known as the foremost Tagalog writer, his most notable work being the 19th-century epic Florante at Laura.
