Origin of bonanza

An Americanism first recorded in 1835–45; from Spanish: literally, “smooth sea” (hence, “good luck, rich vein of ore”), nasalized variant of Medieval Latin bonacia, equivalent to Latin bon(us) “good” + (mal)acia “calm sea,” from Greek malakía “softness” (malak(ós) “soft” + -ia -ia)
