food [food 词源字典]: food: [OE] Food and its Germanic relatives, German futter ‘fodder’, Dutch voedsel ‘food’, and Swedish föda ‘food’, all go back ultimately to a prehistoric Indo-European base *pā-, *pī-, which also produced Latin pābulum ‘fodder’, Russian pisca ‘food’, and Czech pice ‘fodder’. The immediate source of all the Germanic forms was *fōth-, which had two important derivatives: *fōthram, which gave English fodder [OE] and (via Old French) forage [14] and foray [14] (etymologically probably a ‘search for food’); and *fōstrom, source of English foster.

quintessence: quintessence: [15] Just as modern particle physicists search for the ultimate constituent of matter, the common denominator of all known forces, so medieval alchemists tried to find a fifth primary essence, which together with earth, air, fire, and water formed the substance of all heaven and earth. This fifth essence, higher and more ethereal than the other four, was postulated by Aristotle, who called it aithēr ‘either’.

Another Greek term for it was pemptē ousíā ‘fifth essence’, which was translated into medieval Latin as quinta essentia – whence, via French, English quintessence. The metaphorical sense ‘most perfect or characteristic embodiment’ began to emerge in the second half of the 16th century. Other English words based on quintus ‘fifth’, the ordinal form of Latin quinque ‘five’, include quintet [19] and quintuple [16].
alchemy (n.): mid-14c., from Old French alchimie (14c.), alquemie (13c.), from Medieval Latin alkimia, from Arabic al-kimiya, from Greek khemeioa (found c.300 C.E. in a decree of Diocletian against "the old writings of the Egyptians"), all meaning "alchemy." Perhaps from an old name for Egypt (Khemia, literally "land of black earth," found in Plutarch), or from Greek khymatos "that which is poured out," from khein "to pour," related to khymos "juice, sap" [Klein, citing W. Muss-Arnolt, calls this folk etymology]. The word seems to have elements of both origins.
Mahn ... concludes, after an elaborate investigation, that Gr. khymeia was probably the original, being first applied to pharmaceutical chemistry, which was chiefly concerned with juices or infusions of plants; that the pursuits of the Alexandrian alchemists were a subsequent development of chemical study, and that the notoriety of these may have caused the name of the art to be popularly associated with the ancient name of Egypt. [OED]
The al- is the Arabic definite article, "the." The art and the name were adopted by the Arabs from Alexandrians and thence returned to Europe via Spain. Alchemy was the "chemistry" of the Middle Ages and early modern times; since c. 1600 the word has been applied distinctively to the pursuit of the transmutation of baser metals into gold, which, along with the search for the universal solvent and the panacea, were the chief occupations of early chemistry.
conquer (v.): c. 1200, cunquearen, from Old French conquerre "conquer, defeat, vanquish," from Vulgar Latin *conquaerere (for Latin conquirere) "to search for, procure by effort, win," from Latin com-, intensive prefix (see com-), + quaerere "to seek, gain" (see query (v.)). Related: Conquered; conquering.
initialism (n.): word formed from the first letters of other words or a phrase, 1957, from initial (n.) + -ism. The distinction from acronym is not universally agreed-upon; in general, words such as NATO, where the letters form a word, are regarded as acronyms, those such as FBI, where the letters sound as letters, are initialisms. The use of acronym in entries in this dictionary that are technically initialisms is a deliberate error, because many people only know to search for all such words under "acronym."
purchase (v.): c. 1300, "acquire, obtain; get, receive; procure, provide," also "accomplish or bring about; instigate; cause, contrive, plot; recruit, hire," from Anglo-French purchaser "go after," Old French porchacier "search for, procure; purchase; aim at, strive for, pursue eagerly" (11c., Modern French pourchasser), from pur- "forth" (possibly used here as an intensive prefix; see pur-) + Old French chacier "run after, to hunt, chase" (see chase (v.)).

Originally to obtain or receive as due in any way, including through merit or suffering; specific sense of "acquire for money, pay money for, buy" is from mid-14c., though the word continued to be used for "to get by conquest in war, obtain as booty" up to 17c. Related: Purchased; purchasing.
quest (n.): c. 1300, "an inquest;" early 14c., "a search for something" (especially of judicial inquiries or hounds seeking game), from Old French queste "search, quest, chase, hunt, pursuit; inquest, inquiry" (12c., Modern French quête), properly "the act of seeking," and directly from Medieval Latin questa "search, inquiry," alteration of Latin quaesitus (fem. quaesita) "sought-out, select," past participle of quaerere "seek, gain, ask" (see query (n.)). Romance sense of "adventure undertaken by a knight" (especially the search for the Grail) is attested from late 14c. Johnson's dictionary has questmonger "Starter of lawsuits or prosecutions."
seek (v.): Old English secan "inquire, search for; pursue; long for, wish for, desire; look for, expect from," influenced by Old Norse soekja, both from Proto-Germanic *sokjan (cognates: Old Saxon sokian, Old Frisian seka, Middle Dutch soekan, Old High German suohhan, German suchen, Gothic sokjan), from PIE *sag-yo-, from root *sag- "to track down, seek out" (cognates: Latin sagire "to perceive quickly or keenly," sagus "presaging, predicting," Old Irish saigim "seek"). The natural modern form of the Anglo-Saxon word as uninfluenced by Norse is in beseech. Related: Sought; seeking.
riff-raff: "Disreputable or undesirable people", Late 15th century (as riff and raff): from Old French rif et raf 'one and all, every bit', of Germanic origin. More rifle from Middle English:The Old French rifler meant both ‘to plunder’ and to ‘to scratch’. The plunder sense developed via ‘search for valuables’ into ‘to search thoroughly’ (mid 17th century). The word was then re-borrowed from French in the ‘scratch’ sense for the making of grooves in the barrel of a gun (mid 17th century). These rifled guns then became known as rifles (mid 18th century). Riff-raff (Middle English), formerly written as riff and raff, is probably also from rifler combined with raffler ‘to carry off’. The sense ‘disreputable person’ would have developed in much the same way as vulgar and hoi poloi.
