witch

The noun is from Middle English wicche, from Old English wiċċe (“(female) witch; sorceress”) and wiċċa (“(male) witch; sorcerer; warlock”), deverbative from wiċċian (“to practice sorcery”), from Proto-Germanic *wikkōną (compare West Frisian wikje, wikke (“to foretell; to warn”), German Low German wicken (“to soothsay”), Dutch wikken, wichelen (“to dowse; to divine”)), from Proto-Indo-European *wik-néh₂-, derivation of *weyk- (“to consecrate; to separate”); akin to Latin victima (“sacrificial victim”), Lithuanian viẽkas (“life-force”), Sanskrit वि॒नक्ति॑ (vinákti, “to set apart; to separate out”). Possibly related to wicked; see that entry for more. The verb derives from the noun.

The mathematical curve derives from a translation by John Colson of the Italian versiera, from a confusion with versoria (“rope”) and avversaria (“witch”).

From Middle English wicchen, from Old English wiċċian, from Proto-Germanic *wikkōną, from Proto-Indo-European *wik-néh₂-, derivation of *weyk-. In the senses arising in Middle English and later probably aphetic from bewitch.
