also boot-leg, "upper part of the leg of a boot," 1630s, from boot (n.1) + leg (n.). As an adjective in reference to illegal liquor, 1889, American English slang, from the trick of concealing a flask of liquor down the leg of a high boot. Before that the bootleg was the place to secret knives and pistols. Extended to unauthorized music recordings, etc., by 1957.
"part of the human body where pelvis and thigh join," Old English hype "hip," from Proto-Germanic *hupiz (source also of Dutch heup, Old High German huf, German Hüfte, Swedish höft, Gothic hups "hip"), of uncertain origin. In architecture, "external angle at the junction of two sides of a roof," from late 17c. Hip-flask, one meant to fit in a hip pocket, is from 1923. Related: Hips.
"vessel used for holding liquids," late 14c., from Medieval Latin phiola, from Latin phiala, from Greek phialē "flat vessel, dish, flat bowl for drinking or sacrificing," a loan-word of unknown origin. It also came to Middle English via Old French fiole "flask, phial" (12c.), hence the diversity of Middle English spellings (fiole,phiole,phial,fial,viole,vial,viele) and modern vial.
"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 is probably a diminutive of Greek bikos "earthenware jug, wine jar, vase with handles," also a unit of measure, a word of uncertain origin.
It is sometimes said to be a Semitic word, perhaps a borrowing from Syrian buqa "a two-handed vase or jug," or from Egyptian b:k.t "oil flask." The form has been assimilated in English to beak. Originally a drinking vessel; attested by 1877 in reference to a similar glass vessel used in scientific laboratories.
O for a beaker full of the warm South,
Full of the true, the blushful Hippocrene,
With beaded bubbles winking at the brim,
And purple-stained mouth;
That I might drink, and leave the world unseen,
And with thee fade away into the forest dim:
[Keats, from "Ode to a Nightingale"]
