applesauce (n.)youdaoicibaDictYouDict[applesauce 词源字典]
by 1739, American English, from apple + sauce. Slang meaning "nonsense" is attested from 1921 and was noted as a vogue word early 1920s. Mencken credits it to cartoonist T.A. ("Tad") Dorgan. DAS suggests the word was thus used because applesauce was cheap fare served in boardinghouses.[applesauce etymology, applesauce origin, 英语词源]
black (n.)youdaoicibaDictYouDict
Old English blæc "the color black," also "ink," from noun use of black (adj.). From late 14c. as "dark spot in the pupil of the eye." The meaning "black person, African" is from 1620s (perhaps late 13c., and blackamoor is from 1540s). To be in the black (1922) is from the accounting practice of recording credits and balances in black ink.
For years it has been a common practice to use red ink instead of black in showing a loss or deficit on corporate books, but not until the heavy losses of 1921 did the contrast in colors come to have a widely understood meaning. ["Saturday Evening Post," July 22, 1922]
egotism (n.)youdaoicibaDictYouDict
1714, "too frequent use of 'I'," from ego + -ism. First used by Joseph Addison, who credits the term to "Port-Royalists" who used it in reference to obtrusive use of first person singular pronoun in writing, hence "talking too much about oneself." Meaning "self-conceit, selfishness" is from 1800. The -t- is abnormal, perhaps by influence of dogmatism.
ink (n.)youdaoicibaDictYouDict
"the black liquor with which men write" [Johnson], mid-13c., from Old French encre, formerly enque "dark writing fluid" (11c.), originally enca, from Late Latin encaustum, from Greek enkauston "purple or red ink," used by the Roman emperors to sign documents, originally a neuter adjective form of enkaustos "burned in," from stem of enkaiein "to burn in," from en- "in" (see en- (1)) + kaiein "to burn" (see caustic). The word is from a Greek method of applying colored wax and fixing it with heat. The Old English word for it was simply blæc, literally "black." The -r- in the Latin word is excrescent. Donkin credits a Greek pronunciation, with the accent at the front of the word, for the French evolution; the same Latin word became inchiostro in Italian, encausto in Spanish. Ink-blot test attested from 1928.
Ionian (adj.)youdaoicibaDictYouDict
"of Ionia," the districts of ancient Greece inhabited by the Ionians (including Attica and the north coast of the Peloponnesus, but especially the coastal strip of Asia Minor, including the islands of Samos and Chios). The name (which Herodotus credits to an ancestral Ion, son of Apollo and Creusa) probably is pre-Greek, perhaps related to Sanskrit yoni "womb, vulva," and a reference to goddess-worshipping people.

Also used of the sea that lies between Italy and the northern Peloponnesus (1630s). The musical Ionian mode (1844) corresponds to our basic major scale but was characterized by the Greeks as soft and effeminate, as were the Ionians generally.
The Ionians delighted in wanton dances and songs more than the rest of the Greeks ... and wanton gestures were proverbially termed Ionic motions. [Thomas Robinson, "Archæologica Græca," 1807]
jamboree (n.)youdaoicibaDictYouDict
1866, represented as typical of American English, perhaps from jam (n.) on pattern of shivaree [Barnhart]. For the second element, Weekley suggests French bourree, a kind of rustic dance. Klein thinks the whole thing is of Hindu origin (but he credits its introduction to English, mistakenly, to Kipling). Boy Scouts use is from 1920. Noted earlier as a term in cribbage:
Jamboree signifies the combination of the five highest cards, as, for example, the two Bowers [jacks], Ace, King, and Queen of trumps in one hand, which entitles the holder to count sixteen points. The holder of such a hand, simply announces the fact, as no play is necessary; but should he play the hand as a Jambone, he can count only eight points, whereas he could count sixteen if he played it, or announced it as a Jamboree. ["The American Hoyle," New York, 1864]
lost (adj.)youdaoicibaDictYouDict
"defeated," c. 1300; "wasted, spent in vain," c. 1500; also "no longer to be found" (1520s), from past participle of lose. Lost Cause in reference to the Southern U.S. bid for independence is from the title of E.A. Pollard's history of the CSA and the rebellion (1866). Lost Generation in reference to the period 1914-18 first attested 1926 in Hemingway's "The Sun Also Rises," where he credits it to Gertrude Stein. Lost-and-found as the name of a department where misplaced articles are brought or sought is by 1907.
minor (n.)youdaoicibaDictYouDict
early 14c., "a Franciscan," from Latin Fratres Minores "lesser brethren," name chosen by St. Francis, who founded the order, for the sake of humility; see minor (adj.). From c. 1400 as "minor premise of a syllogism." From 1610s as "person under legal age" (Latin used minores (plural) for "the young"). Musical sense is from 1797. Meaning "secondary subject of study, subject of study with fewer credits than a major" is from 1890; as a verb in this sense from 1934.
peacock (n.)youdaoicibaDictYouDict
c. 1300, poucock, from Middle English po "peacock" + coc (see cock (n.)).

Po is from Old English pawa "peafowl" (cock or hen), from Latin pavo (genitive pavonis), which, with Greek taos said to be ultimately from Tamil tokei (but perhaps is imitative; Latin represented the peacock's sound as paupulo).

The Latin word also is the source of Old High German pfawo, German Pfau, Dutch pauw, Old Church Slavonic pavu. Used as the type of a vainglorious person from late 14c. Its flesh superstitiously was believed to be incorruptible (even St. Augustine credits this). "When he sees his feet, he screams wildly, thinking that they are not in keeping with the rest of his body." [Epiphanus]
quiz (n.)youdaoicibaDictYouDict
"brief examination of a student on some subject," 1852, perhaps from quiz (v.), or from slang quiz "odd person" (1782, perhaps originally university slang), via the notion of "schoolboy prank or joke played at the expense of a person deemed a quiz" (a noun sense attested frequently 1840s).
A Quiz, in the common acceptation of the word, signifies one who thinks, speaks, or acts differently from the rest of the world in general. But, as manners and opinions are as various as mankind, it will be difficult to say who shall be termed a Quiz, and who shall not: each person indiscriminately applying the name of Quiz to every one who differs from himself .... ["The London Magazine," November, 1783]
According to OED, the anecdote that credits this word to a bet by the Dublin theater-manager Daly or Daley that he could coin a word is regarded by authorities as "doubtful" and the first record of it appears to be in 1836 (in Smart's "Walker Remodelled"; the story is omitted in the edition of 1840).
The word Quiz is a sort of a kind of a word
That people apply to some being absurd;
One who seems, as t'were oddly your fancy to strike
In a sort of a fashion you somehow don't like
A mixture of odd, and of queer, and all that
Which one hates, just, you know, as some folks hate a cat;
A comical, whimsical, strange, droll -- that is,
You know what I mean; 'tis -- in short, -- 'tis a quiz!

[from "Etymology of Quiz," Charles Dibdin, 1842]
rapport (n.)youdaoicibaDictYouDict
1660s, "reference, relation, relationship," from French rapport "bearing, yield, produce; harmony, agreement, intercourse," back-formation from rapporter "bring back; refer to," from re- "again" (see re-) + apporter "to bring," from Latin apportare "to bring," from ad- "to" (see ad-) + portare "to carry" (see port (n.1)).

Psychological meaning "intense harmonious accord," as between therapist and patient, is first attested 1894, though the word had been used in a very similar sense with reference to mesmerism from 1845 (first recorded in Poe). See also report (n.). Johnson frowns on the word and credits its use in English to Sir William Temple, naturalizer of French terms, who did use it but was not the first to do so.
statement (n.)youdaoicibaDictYouDict
1775, "what is stated," from state (v.) + -ment. From 1789 as "action of stating;" 1885 in the commercial sense "document displaying debits and credits."
