ballast词源

ballast

ballast: [16] Originally, ballast appears to have meant literally ‘bare load’ – that is, a load carried by a ship simply for the sake of its weight, and without any commercial value. English probably acquired it, via Low German, from a Scandinavian language; Old Swedish and Old Danish had not only ballast but also barlast, which appears to betray the word’s component parts: bar, related to English bare, and last ‘burden’ (Old English had hlæst ‘burden’, related to lade, which survived into the 20th century as a measure of weight for various commodities).=> bare, lade

ballast (n.)

\"heavy material used to steady a ship,\" 1520s, from Middle English bar \"bare\" (see bare; in this case \"mere\") + last \"a load, burden,\" or borrowed from identical terms in North Sea Germanic and Scandinavian (compare Old Danish barlast, 14c.). \"Mere\" because not carried for commercial purposes. Dutch balg-last \"ballast,\" literally \"belly-load,\" is a folk-etymology corruption.
