Etymology From Middle English manken, from Old English *mancian, bemancian (“to maim, mutilate”), of obscure origin. Cognate with Middle Low German mank (“lame, defective”), Dutch mank (“lame, defective”), and Middle High German manc (“lack, defect”). Perhaps from Latin mancus (“maimed, crippled, frail, incomplete”), from Proto-Indo-European *mank-, *menk- (“maimed, mutilation, torment”).
