wiktionary
From Middle English been, beene, bene(“gracious, generous, pleasant”), of unknown origin. Perhaps from Old Norse beinn(“straight, right, favourable, advantageous, convenient, friendly, fair, keen”), from Proto-Germanic *bainaz(“straight”), from Proto-Indo-European *bʰeyh₂-(“to hit, beat”).
Cognate with Scots bein, bien(“in good condition, pleasant, well-to-do, cosy, well-stocked, pleasant, keen”), Icelandic beinn(“straight, direct, hospitable”), Norwegian bein(“straight, direct, easy to deal with”). See also bain.
