elixir [elixir 词源字典]: elixir: [14] Although nowadays we think of an elixir as liquid, it probably originated in the Greek word for ‘dry’, xērós (whence English xerox). From this was derived a term for a ‘dry’ powder for treating wounds, xérion, and it has been speculated that this was borrowed by Arabic as (with the definite article al) aliksīr. Medieval alchemists used this as a word for a substance which could change base metals into gold, and also for a substance (according to some the same substance) which could confer immortality (known more fully as the elixir of life).

googol: googol: [20] There are comparatively few ‘new’ words in the English language – that is, words which have not been made up from combinations of old words, or borrowed from other languages, but have sprung up as entirely new growths – but this is one of them. When in the 1930s the American mathematician Dr Edward Kasner was trying to think of a name for an unimaginably large number, ten to the power of a hundred, he asked his nine-year-old nephew Milton Serotta for a suggestion, and googol was what he got. It has never really caught on in technical use, although it has spawned a compound of its own – the googolplex, ten to the power of a googol.
Cheshire: 1086, Cestre Scire, from Chester + scir "district" (see shire). Cheshire cat and its proverbial grin are attested from 1770, but the signification is obscure.
I made a pun the other day, and palmed it upon Holcroft, who grinned like a Cheshire cat. (Why do cats grin in Cheshire?--Because it was once a county palatine, and the cats cannot help laughing whenever they think of it, though I see no great joke in it.) I said that Holcroft, on being asked who were the best dramatic writers of the day, replied, "HOOK AND I." Mr Hook is author of several pieces, Tekeli, &c. You know what hooks and eyes are, don't you? They are what little boys do up their breeches with. [Charles Lamb, letter to Thomas Manning, Feb. 26, 1808]

free (v.): Old English freogan "to free, liberate, manumit," also "to love, think of lovingly, honor;" also "to rid (of something)," from freo "not in bondage" (see free (adj.)).

memento (n.): c. 1400, "Psalm cxxxi in the Canon of the Mass" (which begins with the Latin word Memento and in which the dead are commemorated), from Latin memento "remember," imperative of meminisse "to remember, recollect, think of, bear in mind," a reduplicated form, related to mens "mind" (see mind (n.)). Meaning "reminder, object serving as a warning" is from 1580s; sense of "keepsake" is first recorded 1768.
nuanced (adj.): 1896, past participle adjective from verb nuance (q.v.).
The new co-operative history of English literature which the University of Cambridge is now publishing prints "genre" without italics. And it even permits one contributor--and a contributor who is discussing Shakespeare!--to say that something is delicately "nuanced." Is there now an English verb "to nuance"? It is terrible to think of the bad language the scholars of the venerable English university might have used if "nuanced" had been first discovered in the text of an American author. [Scribner's Magazine," January 1911]
