köken: From Middle High German verwitewet, from Old High German firwituwēt. Originally the past participle of obsolete verwitwen. By surface analysis, ver- + Witwe + -t.
köken: From Latin viduus (“widowed”), probably modeled on the feminine form viuda, which predated it. It may have been altered from an Old Spanish form vidu (itself a learned borrowing from Latin) due to influence from the feminine; a naturally inherited form would be viso, which was attested once in isolation.
