Origin of the Word Pasaman: A Gradual Investigation from Deadlock Toward the Pa-asam-an Hypothesis

This paper is a report on the investigation into the origin of the word Pasaman. The author begins from dissatisfaction with the explanations in circulation, then searches for the closest word to Pasaman in the Minangkabau and Old Malay languages. The closest word found is pa-asam-an. At that stage, however, the author did not yet understand why pa-asam-an became Pasaman, nor what pa-asam-an itself meant. The investigation was then continued into the uses of the word asam in Minangkabau and Old Malay. The phrase ma-asam Sako was found as an example of use. At first, ma-asam was understood literally as sprinkling with acid or preserving with acid. That understanding collapsed after it was realised that Sako is a non-material heirloom that cannot possibly be acid-treated, so ma-asam in that phrase must be a metaphor. The author then still had not found the true meaning of ma-asam beyond metaphor. A breakthrough came only after the author traced the ma-limau-i ritual for the heirloom objects of Puti Sangka Bulan using the ancestral soap made from kanikie fruit (Sapindus rarak), the mandi balimau ritual, and the process of cleaning gold with kanikie by pandai ameh (goldsmiths). From there, the meaning of ma-asam as the process of purifying, processing, repairing, and polishing gold began to emerge. The author then examined in depth the geographical position of Nagari Pasaman on the bank of a river connecting the upstream area where gold was mined and the estuary where a port exported finished gold, and identified Kapa as a candidate for an ancient port at the mouth of that river. The toponym Kapa is highly supportive, but the author stresses that for Kapa there is as yet no empirical evidence. What exists so far is only causal relations and geographical position that strengthen it. This paper therefore stands as a hypothesis open to testing, not a final conclusion.
