A parallel form of sheave, from a Proto-Germanic base which probably existed in Old English (though it is not attested before the Middle English period). Cognate with German Scheibe, late Old Norse skífa ("slice"), brauðskífa (whence Danish skive ("disc, slice")), Dutch schijf ("disc, slice").
From Middle English schyfe, schyffe, from Proto-Germanic *skibō-; cognate with German Schäbe, Dutch scheef, and Low German Schääv, all ‘fragment of the woody core of flax or hemp’.
