Munchkin (n.)youdaoicibaDictYouDict
1900, coined by U.S. author L. Frank Baum (1856-1919) in "The Wonderful Wizard of Oz." He never explained how he got the word. The word most like it is perhaps mutchkin, an old Scottish measure of capacity for liquids, which was used by Scott. (It comes from Middle Dutch mutseken, originally "a little cap," from mutse "cap," earlier almutse "amice, hood, headdress," from Latin amictus "mantle, cloak," noun use of past participle of amicire "to wrap, throw around," a compound from ambi- (see ambi-) + iacere (see jet (v.).)

Latin mundus also was used of a woman's "ornaments, dress," and is related to the adjective mundus "clean, elegant" (used of women's dress, etc.). Related: Mundanely.

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"]
municipal (adj.)youdaoicibaDictYouDict
1540s, from Middle French municipal, from Latin municipalis "of a citizen of a free town, of a free town," also "of a petty town, provincial," from municipium "free town, city whose citizens have the privileges of Roman citizens but are governed by their own laws," from municeps "citizen, inhabitant of a free town." Second element is root of capere "assume, take" (see capable). First element is from munus (plural munia) "service performed for the community, duty, work," also "public spectacle paid for by the magistrate, (gladiatorial) entertainment, gift," from Old Latin moenus "service, duty, burden," from PIE *moi-n-es-, generally taken as a suffixed form of root *mei- (1) "to change, go, move" (Watkins; see mutable); but Tucker says "more probably" from the other PIE root *mei- meaning "bind," so that munia = "obligations" and communis = "bound together."

mural (n.)youdaoicibaDictYouDict
painting on a wall, 1921, short for mural painting (1850), from mural (adj.) "pertaining to walls" (mid-15c.), from Latin muralis "of a wall," from murus "wall" (Old Latin moiros, moerus), from PIE *mei- "to fix; to build fences or fortifications" (cognates: Old English mære "boundary, border, landmark;" Old Norse -mæri "boundary, border-land;" Latin munire "to fortify, protect").
murder (n.)youdaoicibaDictYouDict
c. 1300, murdre, from Old English morðor (plural morþras) "secret killing of a person, unlawful killing," also "mortal sin, crime; punishment, torment, misery," from Proto-Germanic *murthra- (cognates: Goth maurþr, and, from a variant form of the same root, Old Saxon morth, Old Frisian morth, Old Norse morð, Middle Dutch moort, Dutch moord, German Mord "murder"), from PIE *mrtro-, from root *mer- "to die" (see mortal (adj.)). The spelling with -d- probably reflects influence of Anglo-French murdre, from Old French mordre, from Medieval Latin murdrum, from the Germanic root.

Viking custom, typical of Germanic, distinguished morð (Old Norse) "secret slaughter," from vig (Old Norse) "slaying." The former involved concealment, or slaying a man by night or when asleep, and was a heinous crime. The latter was not a disgrace, if the killer acknowledged his deed, but he was subject to vengeance or demand for compensation.
Mordre wol out that se we day by day. [Chaucer, "Nun's Priest's Tale," c. 1386]
Weakened sense of "very unpleasant situation" is from 1878.
