oker

Etymology

Comes from Middle English oker, okur, okir, okyr, ocker, which traces back to Old Norse ókr ('usury'), from Proto-Germanic *wōkraz ('progeny, earnings, profit'), ultimately from Proto-Indo-European *h₂ewg- ('to add, increase'). It is cognate with Scots ocker ('usury'), Icelandic ókur ('usury'), Swedish ocker ('usury'), German Wucher ('usury'), Dutch woeker ('usury'), Old English wōcor ('increase, growth, fruit, usury'), Gothic ????? (wōkrs, 'interest, usury, tax'), and Latin augere ('to increase'). See also eke and wax.
