beaker: [14] The immediate source of beaker was Old Norse bikarr. It is widespread in the West Germanic languages (German has becher, for instance), and it seems likely that Old Norse acquired it from Old Saxon bikeri. But it was borrowed into prehistoric West Germanic from medieval Latin bicarius, which in turn goes back to Greek bikos ‘earthenware jug’ (ultimate source of English pitcher [13]). => pitcher
beaker (n.)
"open large-mouthed vessel," mid-14c., from Old Norse bikarr or Middle Dutch beker "goblet," probably (with Old Saxon bikeri, Old High German behhari, German Becher) from Medieval Latin bicarium, which itself is probably a diminutive of Greek bikos "earthenware jug, wine jar" (said to be an oriental word, perhaps a borrowing from Syrian buqa "a two-handed vase or jug"). Form assimilated in English to beak.
