be-
word-forming element of verbs and nouns from verbs, with a wide range of meaning: "about, around; thoroughly, completely; to make, cause, seem; to provide with; at, on, to, for;" from Old English be- "about, around, on all sides" (the unstressed form of bi "by;" see by (prep.)). The form has remained by- in stressed positions and in some more modern formations (bylaw, bygones, bystander).
The Old English prefix also was used to make transitive verbs and as a privative prefix (as in behead). The sense "on all sides, all about" naturally grew to include intensive uses (as in bespatter "spatter about," therefore "spatter very much," besprinkle, etc.). Be- also can be causative, or have just about any sense required. The prefix was productive 16c.-17c. in forming useful words, many of which have not survived, such as bethwack "to thrash soundly" (1550s) and betongue "to assail in speech, to scold" (1630s).
sot n.
late Old English sott "stupid person, fool," a sense now obsolete, from Old French sot, from Gallo-Roman *sott- (probably related to Medieval Latin sottus), a word of uncertain origin, with cognates from Portugal to Germany. The surviving English meaning "one who is stupefied with drink, one who commonly drinks to excess" is attested by 1590s. As a verb, it is attested from c. 1200, but this is usually besot.
