ragyoudaoicibaDictYouDict[rag 词源字典]
rag: English has four separate words rag, none of them with very well-documented histories. The origins of the oldest, ‘rough building stone’ [13], are completely unknown. Rag ‘piece of cloth’ [14] is probably a back-formation from ragged [13], which was adapted from Old Norse roggvathr ‘tufted’. This in turn was derived from rogg ‘tuft of fur’, but no one knows where that came from. Rag ‘taunt, piece of fun’ [18] is completely mysterious, although some connection with Danish dialect rag ‘grudge’ has been suggested. And finally rag ‘syncopated jazz’ [19] is short for ragtime, which is probably an alteration of ragged time.
[rag etymology, rag origin, 英语词源]
gallivant (v.)youdaoicibaDictYouDict
"gad about, spend time in frivolous pleasure-seeking, especially with the opposite sex," 1809, of uncertain origin, perhaps a playful elaboration of gallant in an obsolete verbal sense of "play the gallant, flirt, gad about." Related: Gallivanted; gallivanting.
Young Lobski said to his ugly wife,
"I'm off till to-morrow to fish, my life;"
Says Mrs. Lobski, "I'm sure you a'nt",
But you brute you are going to gallivant."

What Mrs. Lobski said was right,
Gay Mr. Lobski was out all night.
He ne'er went to fish, 'tis known very well
But where he went I shall not tell.

indisposed (adj.)youdaoicibaDictYouDict
c. 1400, "unprepared;" early 15c., "not in order," from in- (1) "not" + disposed; or else from Late Latin indispositus "without order, confused." Mid-15c. as "diseased;" modern sense of "not very well" is from 1590s. A verb indispose is attested from 1650s but is perhaps a back-formation of this.
intermission (n.)youdaoicibaDictYouDict
early 15c., from Latin intermissionem (nominative intermissio) "interruption," noun of action from past participle stem of intermittere "to leave off," from inter- "between" (see inter-) + mittere "let go, send" (see mission).
Intermission is used in U.S. for what we call an interval (in a musical or dramatic performance). Under the influence of LOVE OF THE LONG WORD, it is beginning to infiltrate here and should be repelled; our own word does very well. [H.W. Fowler, "Modern English Usage," 1926]
poker (n.2)youdaoicibaDictYouDict
card game, 1834, American English, of unknown origin, perhaps from the first element of German Pochspiel, name of a card game similar to poker, from pochen "to brag as a bluff," literally "to knock, rap" (see poke (v.)). A popular alternative theory traces the word to French poque, also said to have been a card game resembling poker. "[B]ut without documentation these explanations are mere speculation" [Barnhart]. The earlier version of the game in English was called brag. Slang poker face (n.) "deadpan" is from 1874.
A good player is cautious or bold by turns, according to his estimate of the capacities of his adversaries, and to the impression he wants to make on them. 7. It follows that the possession of a good poker face is an advantage. No one who has any pretensions to good play will betray the value of his hand by gesture, change of countenance, or any other symptom. ["Cavendish," "Round Games at Cards," dated 1875]



To any one not very well up in these games, some parts of the book are at first sight rather puzzling. "It follows," we read in one passage, "that the possession of a good poker face" (the italics are the author's) "is an advantage." If this had been said by a Liverpool rough of his wife, the meaning would have been clear to every one. Cavendish, however, does not seem to be writing especially for Lancashire.

smog (n.)youdaoicibaDictYouDict
1905, blend of smoke and fog, formed "after Lewis Carrol's example" [Klein; see portmanteau]. Reputedly coined in reference to London, and first attested there in a paper read by Dr. H.A. des Voeux, treasurer of the Coal Smoke Abatement Society, though he seems not to have claimed credit for coining it.
At a recent health congress in London, a member used a new term to indicate a frequent London condition, the black fog, which is not unknown in other large cities and which has been the cause of a great deal of bad language in the past. The word thus coined is a contraction of smoke fog "smog" -- and its introduction was received with applause as being eminently expressive and appropriate. It is not exactly a pretty word, but it fits very well the thing it represents, and it has only to become known to be popular. ["Journal of the American Medical Association," Aug. 26, 1905]
Smaze (with haze (n.)) is from 1953.
wail (v.)youdaoicibaDictYouDict
c. 1300 (intransitive); mid-14c. (transitive), from Old Norse væla "to lament," from "woe" (see woe). Of jazz musicians, "to play very well," attested from 1955, American English slang (wailing "excellent" is attested from 1954). Related: Wailed; wailer.
