"of or pertaining to a midwife or midwifery," 1742, from Modern Latin obstetricus "pertaining to a midwife," from obstetrix (genitive obstetricis) "midwife," literally "one who stands opposite (the woman giving birth)," from obstare "stand opposite to" (see obstacle). The true adjective would be obstetricic, "but only pedantry would take exception to obstetric at this stage of its career" [Fowler]. Related: Obstetrical.
also résumé, 1804, "a summary, summing up, recapitulation," from French résumé, noun use of past participle of resumer "to sum up," from Latin resumere "take again, take up again" (see resume (v.)). Meaning "biographical summary of a person's career" is 1940s.
late 15c., "lasciviousness," from French lubricité or directly from Medieval Latin lubricitatem (nominative lubricitas) "slipperiness," from Latin lubricus "slippery; easily moved, sliding, gliding;" figuratively "uncertain, hazardous, dangerous; seductive" (from suffixed form of PIE root *sleubh- "to slip, slide"). Sense of "oiliness, smoothness" in English is from 1540s; figurative sense of "shiftiness" is from 1610s.
The priests had excellent cause to forbid us lechery: this injunction, by reserving to them acquaintance with and absolution for these private sins, gave them an incredible ascendancy over women, and opened up to them a career of lubricity whose scope knew no limits. [Marquis de Sade, "Philosophy in the Bedroom"]
"to discredit a candidate for some position by savaging his or her career and beliefs," 1987, from name of U.S. jurist Robert H. Bork, whose Supreme Court nomination in 1987 was rejected after an intense counter-campaign. Similar instances had happened before:
[John Quincy Adams's] printed assault upon Jonathan Russell—who had been so ill-advised as to cast doubts upon the patriotism of Adams's conduct at Ghent—was so deadly that for many years afterwards the vocabulary of America was increased, though not enriched, by the transitive verb "to Jonathan-Russell," meaning to pulverize an opponent. [George Dangerfield, "The Era of Good Feeling," 1953]
"servile black man," 1922, somewhat inaccurately in reference to the humble, pious, but strong-willed main character in Harriet Beecher Stowe's novel, "Uncle Tom's Cabin" (1852). The image implied in the insult perhaps is more traceable to the late 19c. minstel show versions of the story, which reached a far wider audience than the book.
I don't recall anyone in the 1920s using the term 'Uncle Tom' as an epithet. But what's amazing is how fast it caught on (in the 1930s). Black scholars picked up (the term) and just started throwing it at each other. [Ernest Allen, quoted in Hamilton, Kendra, "The Strange Career of Uncle Tom," Black Issues in Higher Education, June 2002]
As a verb, attested from 1937.
1610s, of persons, "controlled by conscience, governed by the known rules of right and wrong;" of conduct, etc., "regulated by conscience," 1630s, from French conscientieux (16c.; Modern French consciencieux), from Medieval Latin conscientiosus, from Latin conscientia "sense of right, moral sense" (see conscience). Related: Conscientiously; conscientiousness.
Conscientious objector is from 1896, in reference to those with religious scruples about mandatory vaccination. Military sense predominated from World War I.
After a chequered career full of startling episodes and reversals, the Vaccination Bill becomes virtually the Vaccination Act. In Parliament the hottest of the contest centred round the conscientious objector. [The Lancet, Aug. 13, 1898]
Slang shortening conchy is attested from 1917.
1867, "calf or yearling found without an owner's brand," a word from the great cattle ranches of the American West, so called for Samuel A. Maverick (1803-1870), Texas cattle owner who was notoriously negligent in branding his calves.
All neat stock found running at large in this State, without a mother, and upon which there is neither mark nor brand, shall be deemed a maverick, and shall be sold to the highest bidder for cash, at such time and place, and under such rules and regulations, as the round-up commissioners of the district shall prescribe. [act to amend the General Statutes of the State of Colorado, approved April 8, 1885]
The family name is an old one in Boston, and a different Samuel Maverick was killed in the Boston Massacre. The sense of "individualist, unconventional person" is said to be attested by 1886, via the notion of "masterless," but its modern popularity seems to date to the late 1930s and the career of Maury Maverick (1895-1954) of Texas, grandson of Samuel the rancher and a Democratic congressman 1935-1939 famous for his liberal independent streak, who also coined gobbledygook.
"The Crisis" (April 1939) wrote that "During his stormy career in Washington Maverick became known as the one dependable liberal among the southerners. He recognized the broad problems of our nation, refusing to allow his vision to be limited by sectional prejudices, or racial or economic bugaboos. He was the only southern congressman to vote for the Gavagan federal anti-lynching bill. Not only did he vote for it, but he made a speech on the floor of the House in support of it."
