Of Unknown origin. Suggestions have included Proto-Indo-European *bekione (“double, partner”), Latin *bissōne (“double”), and a a pre-Roman *bikione related to Basque biki (“twin”), biko (“pair”), and bikun (“double”). Compare also Occitan besson, from the same Old Occitan root.
Probably from a semantic variation of ametlla bessona (“conjoined almond”).
