pessimismyoudaoicibaDictYouDict[pessimism 词源字典]
pessimism: [18] The first English writer on record as using pessimism was the poet Coleridge, in the 1790s. But he employed it for the ‘worst possible state’. The modern sense ‘expecting the worst’ did not emerge until the early 19th century. The word was probably coined first in French, and was based on Latin pessimus ‘worst’.

bear (n.)youdaoicibaDictYouDict
Old English bera "bear," from Proto-Germanic *beron, literally "the brown (one)" (cognates: Old Norse björn, Middle Dutch bere, Dutch beer, Old High German bero, German Bär), from PIE *bher- (3) "bright, brown" (see brown (adj.)).

Greek arktos and Latin ursus retain the PIE root word for "bear" (*rtko; see Arctic), but it is believed to have been ritually replaced in the northern branches because of hunters' taboo on names of wild animals (compare the Irish equivalent "the good calf," Welsh "honey-pig," Lithuanian "the licker," Russian medved "honey-eater"). Others connect the Germanic word with Latin ferus "wild," as if it meant "the wild animal (par excellence) of the northern woods."

Symbolic of Russia since 1794. Used of uncouth persons since 1570s. Stock market meaning "speculator for a fall" is 1709 shortening of bearskin jobber (from the proverb sell the bearskin before one has caught the bear); i.e. "one who sells stock for future delivery, expecting that meanwhile prices will fall." Paired with bull from c. 1720. Bear claw as a type of large pastry is from 1942, originally chiefly western U.S.
birthmark (n.)youdaoicibaDictYouDict
also birth-mark, by 1805, from birth (n.) + mark (n.1). Birth marks in 17c. could be longing marks; supposedly they showed the image of something longed for by the mother while expecting. Related: Birthmarked.
expect (v.)youdaoicibaDictYouDict
1550s, "wait, defer action," from Latin expectare/exspectare "await, look out for; desire, hope, long for, anticipate; look for with anticipation," from ex- "thoroughly" (see ex-) + spectare "to look," frequentative of specere "to look at" (see scope (n.1)).

Figurative sense of "anticipate, look forward to" developed in Latin and is attested in English from c. 1600. Also from c. 1600 as "regard as about to happen." Meaning "count upon (to do something), trust or rely on" is from 1630s. Used since 1817 as a euphemism for "be pregnant." In the sense "suppose, reckon, suspect," it is attested from 1640s but was regarded as a New England provincialism. Related: Expected; expecting.
MunichyoudaoicibaDictYouDict
Bavarian capital, German München, from root of Mönch "monk" (see monk); founded 1158 as a market town by Benedictine monks. In allusions to "appeasement" it is from the meeting of German, British, French and Italian representatives there in Sept. 29, 1938, which resulted in the cession of Sudetenland to Germany in exchange for Hitler's pledges.
During the flight Daladier sat silent and morose, worried about the reception he would receive at Le Bourget, about how the French would react to his having betrayed Czechoslovakia and France's promises. As the plane circled for landing, he and others saw a massive crowd awaiting them. Expecting jeers, hisses, rotten fruit, and maybe worse, Daladier declared stolidly: 'They are going to mob me, I suppose. ... I appreciate their feelings,' and insisted on absorbing their wrath by being the first off the plane. But as he stood dumbfounded on the gangplank, thousands surged forward carrying flags and flowers, shouting 'Hurrah for France! Hurrah for England! Hurrah for peace!' Daladier turned back to Léger and cursed, 'The God-damned fools!' [Benjamin F. Martin, "France in 1938"]
pregnant (adj.1)youdaoicibaDictYouDict
"with child," early 15c., from Latin praegnantem (nominative praegnans, originally praegnas) "with child," literally "before birth," probably from prae- "before" (see pre-) + root of gnasci "be born" (see genus).

Retained its status as a taboo word until c. 1950; modern euphemisms include anticipating, enceinte, expecting, in a family way, in a delicate (or interesting) condition. Old English terms included mid-bearne, literally "with child;" bearn-eaca, literally "child-adding" or "child-increasing;" and geacnod "increased." Among c. 1800 slang terms for "pregnant" was poisoned (in reference to the swelling).
