 Tagalog is closely 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.The word "Tagalog" is derived from the endonym "taga-ilog" ("river dweller"), composed of "tagá-" ("native of" or "from") and "ilog" ("river").Linguists such as Dr. David Zorc and Dr. Robert Blust speculate that the Tagalogs and other Central Philippine ethno-linguistic groups originated in Northeastern Mindanao or the Eastern Visayas.
