Etymology: "Coumarous" is the plural of "coumarou," a word borrowed from French and originally from Old Tupi "kumaru," a name for the tonka bean, the seed of a South American tree. The adjective describes things resembling coumarin, the sweet-smelling compound first isolated from tonka beans, which takes its name from the same source.
