binolalangaw n. [Old Boie’nen]
A mutant coconut whose endosperm develops as a thick, gelatinous mass with little to no coconut water, equivalent to Tagalog makapuno.
Morphology: -in- (infix) + bolalangaw “rainbow”. Lit. “rainbow-fed” or “that which the rainbow has passed over”. The -in- infix marks a state resulting from an external agent.
Folk etiology: Early Boie’nen believed the nut’s water was drunk by a bolalangaw that came down to feed, leaving the meat unnaturally dense and sweet. Finding a binolalangaw was read as paligsek “omen” because the trait does not breed true — a single tree yields it only rarely.
Usage: “Binolalangaw adi, seksek pagki’ten a lokad.”
“This is binolalangaw, ita meat is full and densely packed.”
Scientific parallel: Caused by a recessive mutation that prevents normal liquid endosperm formation.
