bonanza [bonanza 词源字典]: bonanza: [19] Bonanza entered the language via American English from Spanish, where bonanza means ‘prosperity’, or literally ‘good weather’. It came from an unrecorded general Romance *bonacia, a derivative of Latin bonus ‘good’. (Other English words acquired ultimately from bonus – a descendant of Old Latin duenos – include bonbon [19], bonus [18], boon [14] (as in ‘boon companion’), bounty [13] (from Latin bonitas ‘goodness’), and perhaps bonny [15].) It appears to have been formed on the analogy of Latin malacia, as if this meant ‘bad weather’, from malus ‘bad’, although it in fact originally meant ‘calm at sea’, from Greek malakós.
