Etymology: Spumous is a fairly transparent English word: it comes from Middle English "spumous", borrowed from the Latin "spūmōsus", meaning "foamy" or "frothy". The Latin adjective is built from "spūma", "foam", with the suffix "-ōsus", which Latin used to form adjectives meaning "full of" the base noun, so the word literally means "full of foam." English has many of these pairs, such as "mucous" from "mucus" or "vinous" from "vinum." The noun "spūma" reaches back to a Proto-Indo-European root that also produced words for spitting and blowing, which fits the way foam forms when liquid is agitated and sprays. The Latin noun itself passed into English largely as "spume," so "spumous" and "spume" are close relatives, the adjective and noun sharing a single stem.
