Word Origin and History for beaker

"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.
