Batangas — Possible Austronesian Root of the Name

Among the folkloric etymologies of the name Batangas is that this was supposed to have been from the by-now archaic Tagalog batang, meaning “logs.” The word “folkloric” is used inasmuch as most sources over the Internet, including the official site¹ of the City of Batangas, do not cite sources.

Hence, for the purposes of this article, the convenient presumption is that the etymology is derived from oral tradition. According to this tradition, the name was given because the native settlers near the Calumpang River, which runs through what is now the City of Batangas, called their settlement “Batangan” from the batang or numerous logs floating on the river².

Since in Tagalog, the suffix -an can loosely mean “a/the place where something abounds or can be found or is located," then batangan would have meant, to translate loosely into English, “the place of many logs.”

In the present day, of course, hardly anyone — if at all — uses the word batang, which has been superseded by troso to mean “log.” The latter is obviously a loan word from the Spanish trozo, although in its strict sense, a trozo means a piece or part of a tree trunk that has been cut.

The slight change from Batangan to Batangas is outside the scope of this article, so we will continue to stay with the batang etymology. While the story, in the absence of scholarly documentation, is probably folkloric, venturing into Austronesian linguistics gives this etymology credence and plausibility.

The Austronesians, to put things succinctly, were a seafaring people who went on seaborne migrations from southeastern China and later Taiwan between 3000 and 1500 BCE to reach as far east as Easter Island in the Pacific Ocean and as far west as Madagascar³. This migration is often referred to in the present day in scholarly circles as the “Out of Taiwan” model, a theory which explains how the Philippines, Southeast Asia, and the Pacific islands and Madagascar were populated⁴.

The primary proponents of this theory were the archeologist Peter Bellwood and the linguist Robert Blust. It is the linguistic angle that we shall now begin to explore with regards to the word batang.

The word is not merely archaic or old Tagalog but can be traced back to Proto-Austronesian, the reconstructed ancestor of the Austronesian languages⁵.

In this reconstructed language, the word batang is spelled as “bataŋ.” The ŋ symbol represents what is called the “voice velar nasal, also known as eng,” the same sound as ng in English or Tagalog⁶. In other words, batang sounds exactly the same as “bataŋ.”

In “The Austronesian Comparative Dictionary,” with content primarily contributed by the linguist Blust, bataŋ’s meaning is, indeed, given as “tree trunk, fallen tree, log, stem of a plant.” Other meanings include body, corpse, self, the bridge of the nose, the most important or preeminent thing, main course of a river, and mushroom or bracket fungus that grows on tree trunks or decaying logs⁷.

Moreover, “bataŋ” is not merely old Tagalog but has cognates — words that sound and mean the same in different languages — in Cebuano, Hanunoo (a Mangyan language), Batak (Palawan), Binukid (Northern Mindanao), Manobo (Western Mindanao), Tausug (Sulu Archipelago), and others⁸.

The word also has cognates as well in non-Philippine languages such as Lundayeh, Bintulu, and Kenyah (Borneo), Gayo (Indonesia), Berawan (Malaysia), and others⁹.

Its variants include bitáŋ (Agta, Cagayan), bótóŋ (Tboli), wata (Uma language, Sulawesi) and wataŋ (Maranao)¹⁰.

In the absence of credible documentation about the supposed presence of logs along the Calumpang River, which would have been referred to by natives as Batangan, this story will naturally continue to remain under the blanket term folklore. However, that the story exists at all and that the name batang is linguistically verifiable to mean logs does give the story a fairly high degree of plausibility.
