originFrom French furibond (“furious”) and Middle English furybound, furybounde, both borrowed from Latin furibundus (“frantic, frenzied; maddened, raving; inspired”), from furō (“to rave, rage”) + -bundus (suffix forming adjectives with an active or transitive meaning). The further etymology of furō is uncertain; a derivation from Proto-Indo-European *dʰewh₂- (“smoke; haze, mist”) has been suggested.
