O.E.
beor of much-disputed and ambiguous origin, but prob. a 6c. W.Ger. monastic borrowing of V.L.
biber "a drink, beverage" (from L. infinitive
bibere "to drink;" see
imbibe). Another suggestion is that it comes from P.Gmc.
*beuwoz-, from
*beuwo- "barley." The native Gmc. word for the beverage was cognate with
ale (q.v.).
Small beer was originally "weak beer," used figuratively of small things.
"Beer was a common drink among most of the European peoples, as well as in Egypt and Mesopotamia, but was known to the Greeks and Romans only as an exotic product." [Buck]
Gk.
brytos, used in reference to Thracian or Phrygian brews, was related to O.E.
breowan "brew;" L.
zythum is from Gk.
zythos, first used of Egyptian beer and treated as an Egyptian word but perhaps truly Gk. and related to
zyme "leaven." Sp.
cerveza is from L.
cervesia, perhaps related to L.
cremor "thick broth." O.C.S.
pivo, source of the general Slavic word for "beer," is originally "a drink" (cf. O.C.S.
piti "drink").
