verbdialect, archaic, rare British, Midlands English, Scottish
To decay, rot; to crumble or moulder away.
Early 17th century; earliest use found in John Smith (bap. 1580, d. 1631), soldier and colonial governor. Probably from an unattested noun, representing the reflex of a borrowing from early Scandinavian, cognate with Middle Dutch mosch marsh, moss (probably from the same Indo-European base as classical Latin muscus) + -er.
