Etymology

Origin of bonanza

An Americanism first recorded in 1835–45; from Spanish: “calm sea, prosperity, abundance of minerals,” nasalized variant of Medieval Latin bonacia, alteration (with influence from Latin bonus “good,” possibly to avoid confusion with malus “bad”) of Latin malacia “calm sea,” from Greek malakía “softness” ( malak(ós) “soft” + -ia -ia )
