    "Identical with earlier Du. krappe ‘carptus, carptura, res decerpta, frustum decerptum siue abscissum, pars abrasa siue abscissa; pars carnis abscissa; crustum; offella, offula; placenta; pulpamentum’ (Kilian, 1599), connected with krappen to pluck off, cut off, separate. Cf. also F. crape, OF. crappe siftings, also ‘the grain trodden under feet in the barn, and mingled with the straw and dust’ (M. L. Delisle in Godef.), med.L. crappa in Du Cange. (Cf. also crapinum the smaller chaff.) In mod.F. the word has taken the sense of ‘dirt, filth’, and ‘grease of a millstone’. It is doubtful whether all the senses here placed belong to one word, though a common notion of ‘rejected or left matter, residue, dregs, dust’ runs through them."
