 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.
