album (n.)youdaoicibaDictYouDict[album 词源字典]
1650s, from Latin album "white color, whiteness," neuter of albus "white" (see alb). In classical times "a blank tablet on which the Pontifex Maximus registered the principal events of the year; a list of names." Revived 16c. by German scholars whose custom was to keep an album amicorum of colleagues' signatures; meaning then expanded into "book to collect souvenirs." According to Johnson, "a book in which foreigners have long been accustomed to insert autographs of celebrated people." Photographic albums first recorded 1859. Meaning "long-playing gramophone record" is by 1951, because the sleeves they came in resembled large albums.[album etymology, album origin, 英语词源]

alchemist (n.)youdaoicibaDictYouDict
1510s, from Middle French alquemiste, from Medieval Latin alchimista (see alchemy). Earlier forms were alchemister (late 14c.), alkanamyer (late 15c.).
alchemy (n.)youdaoicibaDictYouDict
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.
alcohol (n.)youdaoicibaDictYouDict
1540s (early 15c. as alcofol), "fine powder produced by sublimation," from Medieval Latin alcohol "powdered ore of antimony," from Arabic al-kuhul "kohl," the fine metallic powder used to darken the eyelids, from kahala "to stain, paint." The al- is the Arabic definite article, "the."

"Powdered cosmetic" was the earliest sense in English; definition broadened 1670s to "any sublimated substance, the pure spirit of anything," including liquids. Modern sense of "intoxicating ingredient in strong liquor" is first recorded 1753, short for alcohol of wine, which was extended to "the intoxicating element in fermented liquors." In organic chemistry, the word was extended 1850 to the class of compounds of the same type as this.
alcoholic (adj.)youdaoicibaDictYouDict
1790, "of or pertaining to alcohol;" see alcohol + -ic. Meaning "caused by drunkenness" is attested by 1872; meaning "habitually drunk" by 1910.

Alcoholics Anonymous founded 1935 in Akron, Ohio, U.S. Alky is first recorded 1844 as a slang shortening of "alcoholic liquor;" 1960 in the sense of "a drunkard."
alcoholism (n.)youdaoicibaDictYouDict
"disease of alcohol addiction," 1852, from alcohol + -ism, or else from Modern Latin alcoholismus, coined in 1852 by Swedish professor of medicine Magnus Huss (1807-1890) to mean what we now would call "alcohol poisoning." In earlier times, alcoholism would have been habitual drunkenness or some such term.

alder (n.)youdaoicibaDictYouDict
tree related to the birch, Old English alor "alder" (with intrusive -d- added 14c.; the historical form aller survived until 18c. in literary English and persists in dialects, such as Lancashire owler, which is partly from Norse), from Proto-Germanic *aliso (cognates: Old Norse ölr, Danish elle, Swedish al, Dutch els, German erle), from *el-, the ancient PIE name of the tree (cognates: Russian olicha, Polish olcha, Latin alnus, Lithuanian alksnis).
alderman (n.)youdaoicibaDictYouDict
Old English aldormonn (Mercian), ealdormann (West Saxon) "ruler, prince, chief; chief officer of a shire," from aldor, ealder "patriarch" (comparative of ald "old;" see old) + monn, mann "man" (see man (n.)). A relic of the days when the elders were automatically in charge of the clan or tribe, but already in Old English used for king's viceroys, regardless of age. The word yielded in Old English to eorl, and after the Norman Conquest to count (n.). Meaning "headman of a guild" (early 12c.) passed to "magistrate of a city" (c. 1200) as the guilds became identified with municipal government.

The device characteristic of Aldine books is a figure of a dolphin on an anchor.
