Etymology: Rumbustious sounds like it was born in a Victorian pub brawl, and its origins are genuinely murky. The most likely source is "robustious," an older adjective meaning robust, large, noisy or violent, itself built from "robust" with the suffix "-ious." Rumbustious probably varies that word, with the sound of "rum" added at the front, but the change is not fully explained. A second possibility is that the word was built from "rum," a nonsense syllable of the sort that English speakers have long used to make boisterous words feel bigger and noisier, plus "bust" and "-ious." Neither explanation is proven, so the word's exact recipe remains uncertain. What is clear is the word's sense: it describes someone or something full of boisterous energy, the sort of exuberance that tips over into rowdiness at a party.
