Latin, literally "wonderful to relate," from neuter of mirabilis "wonderful, marvelous, extraordinary; strange, singular" (see marvel (n.)) + ablative supine of dicere "to say, speak" (from PIE root *deik- "to show," also "pronounce solemnly"). The expression is found in Virgil. Mirable "wonderful, marvelous" was used in English 15c.
(1755-1793), queen consort of Louis XVI; as the name for a decorative style of France in that period, by 1887. She likely did not say "let them eat cake" (see cake (n.)). The city of Marietta, Ohio, U.S., founded in 1788, was named for her in honor of Louis XVI's financial support of the American Revolution.
an English notion of a stereotypical French oath, 1869, from French sacré bleu, literally "holy blue," a euphemism for sacré Dieu (1768), "holy God." From Old French sacrer, from Latin sacrare "to make or declare sacred" (see sacred). Such things are never idiomatic. In an old French-language comic set in the U.S. Wild West, the angry cowboys say "Bloody Hell!"
"the order being changed," c. 1600, Latin, from vice, ablative of vicis "a change, alternation, alternate order" (from PIE root *weik- (2) "to bend, to wind") + versa, feminine ablative singular of versus, past participle of vertere "to turn, turn about" (from PIE root *wer- (2) "to turn, bend"). "The phrase has the complete force of a proposition, being as much as to say that upon a transposition of antecedents the consequents are also transposed" [Century Dictionary].
in the sports sense, 1879, originally in cricket, "taking three wickets on three consecutive deliveries;" extended to other sports c. 1909, especially ice hockey ("In an earlier contest we had handed Army a 6-2 defeat at West Point as Billy Sloane performed hockey's spectacular 'hat trick' by scoring three goals" ["Princeton Alumni Weekly," Feb. 10, 1941]). So called allegedly because it entitled the bowler to receive a hat from his club commemorating the feat (or entitled him to pass the hat for a cash collection), but the term probably has been influenced by the image of a conjurer pulling objects from his hat (an act attested by 1876). The term was used earlier for a different sort of magic trick:
Place a glass of liquor on the table, put a hat over it, and say, "I will engage to drink every drop of that liquor, and yet I'll not touch the hat." You then get under the table; and after giving three knocks, you make a noise with your mouth, as if you were swallowing the liquor. Then, getting from under the table, say "Now, gentlemen, be pleased to look." Some one, eager to see if you have drunk the liquor, will raise the hat; when you instantly take the glass and swallow the contents, saying, "Gentlemen I have fulfilled my promise: you are all witnesses that I did not touch the hat." ["Wit and Wisdom," London, 1860]
"statement in passing," a judge's expression of opinion not regarded as binding or decisive, Latin, literally "something said incidentally;" from obiter "by the way" + dictum in the legal sense "a judge's expression of opinion which is not the formal resolution of a case or determination of the court."
Obiter dicta, legal dicta ... uttered by the way (obiter), not upon the point or question pending, as if turning aside for the time from the main topic of the case to collateral subjects. [Century Dictionary]
Latin obiter is from ob "in front of, toward" (see ob-) + iter "journey" (from PIE root *ei- "to go"). Klein's sources, however, say it is ob with the suffix -iter on analogy of circiter "about" from circa. Also see obituary.
