Word Origin & History
mid-14c., "big, clumsy, stupid fellow who lives in idleness," from lobre, earlier lobi "lazy lout," related to lob, and probably of Scandinavian origin. A sailors' word since 16c. (cf. landlubber), but earliest use was of lazy monks (cf. abbey-lubber). Cf. also lubberwort, the name of the mythical herb
that produces laziness (1540s); and Lubberland "imaginary land of plenty without work" (1590s).
