köken: From Middle High German bar, from Old High German bar, from Proto-West Germanic *baʀ, from Proto-Germanic *bazaz (“bare, naked”), from Proto-Indo-European *bʰosós, from *bʰos- (“bare, barefoot”). Hence the meanings "without something" (as in bar jeder Einsicht "from every point of view") and "evident to the naked eye" (attested in Middle High German bar in reference to money).

The former is corroborated by subsequent phonetic data; the later, by the alternative obsolete form kézi pénz.
