Molotov — monomaniac (n.)

Molotov

name taken by Vyacheslav Mikhailovich Skriabin (1890-1986), Soviet minister of foreign affairs 1939-1949, from Russian molot "hammer," cognate with Latin malleus, from PIE root *mele- "to crush, grind." Molotov cocktail "glass bottle filled with flammable liquid and a means of ignition" (1940) is a term from Russo-Finnish War (used and satirically named by the Finns).

molt (v.)

also moult, c. 1400, mouten, of feathers, hair, etc., "to be shed, fall out," from Old English *mutian "to change" (in bemutian "to exchange"), from Latin mutare "to change" (from PIE root *mei- (1) "to change"). Transitive sense, "to shed or cast (feathers, fur, skin)" is by mid-15c. With unetymological -l-, late 16c., on model of fault, etc. Related: Molted, moulted; molting, moulting. As a noun, "act or process of shedding an outer structure or appendage," from 1815.

molten (adj.)

"melted, in a state of solution," c. 1300, from archaic strong past participle of Old English meltian, a class III strong verb (see melt (v.)).

Moluccas

island group of Indonesia, the Spice Islands, attested in French by 1520s as Moluques, from Malay Maluku "main (islands)," from molok "main, chief," perhaps so called for their central location in the archipelago.

molybdenum (n.)

silvery-white metallic element, 1816, from molybdena (1690s), a name used generally for lead-like minerals, from Latinized form of Greek molybdos "lead," also "black graphite," probably borrowed from an Anatolian language. The element was so called because of its resemblance to lead ore. Related: Molybdenous; molybdic.

mom (n.)

"mother," 1867, American English, perhaps a shortening of mommy; also see mamma. Adjectival phrase mom and pop to indicate a small shop or other business run by a married couple is by 1946.

mome (n.)

"buffoon, fool, stupid person," 1550s, from Old French mome "a mask. Related" Momish. The adjective introduced by "Lewis Carroll" is an unrelated nonsense word.

moment (n.)

late 14c., "very brief portion of time, instant," in moment of time, from Old French moment (12c.) "moment, minute; importance, weight, value" and directly from Latin momentum "movement, motion; moving power; alteration, change;" also "short time, instant" (also source of Spanish, Italian momento), contraction of *movimentum, from movere "to move" (from PIE root *meue- "to push away").

Some (but not OED) explain the sense evolution of the Latin word by notion of a particle so small it would just "move" the pointer of a scale, which led to the transferred sense of "minute time division."

In careful use, a moment has duration, an instant does not. The sense of "notable importance, 'weight,' value, consequence" is attested in English from 1520s. Meaning "opportunity" (as in seize the moment) is from 1781.

In for the moment "temporarily, so far as the near future is concerned" (1883) it means "the present time." Phrase never a dull moment is attested by 1885 (Jerome K. Jerome, "On the Stage - and Off"). Phrase moment of truth first recorded 1932 in Hemingway's "Death in the Afternoon," from Spanish el momento de la verdad, the final sword-thrust in a bull-fight.

momentous (adj.)

"of moment or consequence, critical, of surpassing importance," 1650s, from moment + -ous to carry the sense of "important" while momentary kept the meaning "of an instant of time." Related: Momentously; momentousness.

momently (adv.)

1670s, "from moment to moment, every moment," from moment + -ly (2). Meaning "at any moment" is attested from 1775.

momzer (n.)

"contemptible person, moocher," 1560s, from Hebrew, literally "bastard" (used as such in Vulgate), but the modern word (by 1914) is a separate borrowing from Yiddish.

1610s, "unity, arithmetical unit," 1610s, from Late Latin monas (genitive monadis), from Greek monas "unit," from monos "alone" (from PIE root *men- (4) "small, isolated"). In Leibnitz's philosophy, "an ultimate unit of being, a unit of the universal substance" (1748); he apparently adopted the word from Giordano Bruno's 16c. metaphysics, where it referred to a hypothetical primary indivisible substance at once material and spiritual. Related: Monadic; monadism.

Mona Lisa

by 1827 as the name of Leonardo's painting or its subject, Lisa, wife of Francesco del Giocondo (see Gioconda). Mona is said to be a contraction of madonna as a polite form of address to a woman, so, "Madam Lisa." Mona Lisa smile in reference to an appealing but enigmatic expression is by 1899.

Meaning "form of government in which supreme power is in the hands of a monarch" is from early 15c.

monarchist (n.)

"advocate for or believer in monarchy," 1640s, from monarchy + -ist. Related: Monarchistic.

monastic (adj.)

"pertaining to or characteristic of a religious recluse," mid-15c., monastik, from Old French monastique "monkish, monastic" and directly from Medieval Latin monasticus, from Ecclesiastical Greek monastikos "solitary, pertaining to a monk," from Greek monazein "to live alone" (see monastery).

monasticism (n.)

by 1795, "corporate life of communities under religious vows," from monastic + -ism.

Monday (n.)

second day of the week, Middle English monedai, from Old English mōndæg, contraction of mōnandæg "Monday," literally "day of the moon," from mona (genitive monan; see moon (n.)) + dæg (see day). A common Germanic name (compare Old Norse manandagr, Old Frisian monendei, Dutch maandag, German Montag). All are loan-translations of Late Latin Lunæ dies, which also is the source of the day name in Romance languages (French lundi, Italian lunedi, Spanish lunes), itself a loan-translation of Greek Selēnēs hēmera. The name for this day in Slavic tongues generally means "day after Sunday."

Phrase Monday morning quarterback is attested from 1932, Monday being the first day back at work after the weekend, where school and college football games played over the weekend were discussed. Black Monday (late 14c.) is the Monday after Easter day, though how it got its reputation for bad luck is a mystery (none of the usual explanation stories holds water). Saint Monday (1753) was "used with reference to the practice among workmen of being idle Monday, as a consequence of drunkenness on the Sunday" before [OED]. Clergymen, meanwhile, when indisposed complained of feeling Mondayish (1804) in reference to effects of Sunday's labors.

mondo (adj.)

"very much, extreme," 1979, from Italian mondo "world" (from Latin mundus; see mundane); specifically from "Mondo cane," title of a 1961 film, literally "world for a dog" (English title "A Dog's Life"), depicting eccentric human behavior. The word was abstracted from the title and taken as an intensifier.

money (n.)

mid-13c., monie, "funds, means, anything convertible into money;" c. 1300, "coinage, coin, metal currency," from Old French monoie "money, coin, currency; change" (Modern French monnaie), from Latin moneta "place for coining money, mint; coined money, money, coinage."

This is from Moneta, a title or surname of the Roman goddess Juno, near whose temple on the Capitoline Hill money was coined (and in which perhaps the precious metal was stored). The name is said to be from monere "advise, warn, admonish" (on the model of stative verbs in -ere; see monitor (n.)), by tradition with an etymological meaning "admonishing goddess," which is sensible, but the etymology is difficult. A doublet of mint (n.2)).

Extended by early 19c. to include paper recognized and accepted as a substitute for coin. The highwayman's threat your money or your life is attested by 1774. Phrase in the money (1902) originally referred to "one who finishes among the prize-winners" (in a horse race, etc.). The challenge to put (one's) money where (one's) mouth is is recorded by 1942 in African-American vernacular.

Money-grub for "avaricious person, one who is sordidly intent on amassing money" is from 1768; money-grubber is by 1835. The image of money burning a hole in someone's pocket is attested from 1520s (brennyd out the botom of hys purs).

Before that (1930s), it was used for the shaft on Oak Island, Nova Scotia, that supposedly leads to treasure buried by Capt. Kidd or some other pirate. "Whether that name refers to the treasure or the several million dollars spent trying to get the treasure out is unclear." [Popular Mechanics, Sept. 1976]

mong (prep.)

also 'mong, c. 1200 as a shortened form of among. Related: 'Mongst.

monger (n.)

Old English mangere "merchant, trader, broker," agent noun from mangian "to traffic, trade," from Proto-Germanic *mangojan (source also of Old Saxon mangon, Old Norse mangari "monger, higgler"), from Latin mango (genitive mangonis) "dealer, trader, slave-dealer," which is related to mangonium "displaying of wares."

Not in Watkins or de Vaan, but Buck (with Tucker) describes it as "one who adorns his wares to give them an appearance of greater value" and writes it is probably a loan-word based on Greek manganon "means of charming or bewitching."

Used in combinations in English at least since 12c. (fishmonger, cheesemonger, etc.); since 16c. chiefly with overtones of petty and disreputable (for example ballad-monger "inferior poet," 1590s; scandal-monger).

monger (v.)

"to traffic in, deal in," often implying a petty or disagreeable traffic, by 1897, from monger (n.). Not considered to be from Old English mangian. Related: Mongered; mongering (1846).

Mongol

1738 (n.) "one of a people of Mongolia and adjacent regions;" 1763 (adj.), from a native name, said to be from mong "brave." Related: Mongolia.

Mongolian

1738 (adj.) "pertaining to Mongols;" 1839 (n.) "the language of the Mongols," 1846 "a native of Mongolia;" from Mongol + -ian. As a racial classification for Asiatic peoples (including Chinese, Japanese, Turks, Vietnamese, Lapps, Eskimos, etc.) "belonging to the yellow-skinned straight-haired type of mankind" [OED] in J.F. Blumenbach's system, it is attested in English by 1825 in translations of his works.

Mongoloid

1868, adj. and noun, as a racial designation, literally "resembling the Mongols," from Mongol + -oid. Compare Mongolian. In reference to the genetic defect causing mental retardation (mongolism), by 1899, from the typical facial appearance of those who have it. See Down's Syndrome. Such people were called Mongolian from 1866.

mongoose (n.)

"snake-killing ichneumon of India," 1690s, perhaps via Portuguese, from an Indic language (such as Mahrathi mangus "mongoose"), probably ultimately from Dravidian (compare Telugu mangisu, Kanarese mungisi, Tamil mangus). The form of the English word has been altered by folk-etymology.

mongrel (n.)

mid-15c., "individual or breed of dog resulting from repeated crossings or mixture of several different varieties," from obsolete mong "mixture," from Old English gemong "mingling" (base of among), from Proto-Germanic *mangjan "to knead together" (source of mingle), from a nasalized form of PIE root *mag- "to knead, fashion, fit." With pejorative suffix -rel.

The distinction between a mongrel and a hybrid (a cross between two different breeds) is not always observed. Meaning "person not of pure race" is attested from 1540s. As an adjective, "of a mixed or impure breed," from 1570s.

-mony

suffix found in nouns of Latin origin (not an active word-forming element in English) forming nouns from adjectives, nouns, or verbs, from Latin -monia (source also of French -monie, Spanish -monia), from -monium, which was similarly used. The -mon- is related to the -men- of -mentum.

monicker (n.)

see moniker.

moniker (n.)

"person's name, especially a nickname or alias," 1849, said to be originally a hobo term (but monekeer is attested in London underclass from 1851), of uncertain origin; perhaps from monk (monks and nuns take new names with their vows, and early 19c. British tramps referred to themselves as "in the monkery"). Its origins seem always to have been obscure:

Watkins speculates from Old Irish ainm "name."

moniliform (adj.)

"resembling a string of beads," 1787, from Latin monile "collar, necklace," from PIE *mon- "neck, nape of the neck" + -form.

monism (n.)

a word used in philosophy and metaphysics of systems of thought which deduce all phenomena from a single principle (1832); also "the doctrine that only one being exists" (1862), from German Monism (by 1818) or directly from Modern Latin monismus, from Greek monos "alone" (from PIE root *men- (4) "small, isolated"); also see -ism. First used in German by German philosopher Baron Christian von Wolff (1679-1754), who applied it to those who deny the substantiality either of mind or matter. Fowler defines it as "any view of that makes the universe consist of mind with matter as a form of mind, or of matter with mind as a form of matter, or of a substance that in every part of it is neither mind nor matter but both," and writes that it is a contrast to dualism.

monist (n.)

"adherent of the metaphysical doctrine of monism" in any sense, 1836, from Greek monos "single" (from PIE root *men- (4) "small, isolated") + -ist. Also see monism. Related: Monistic.

monition (n.)

c. 1400, monicioun, "warning, instruction given by way of caution," from Old French monition (13c.) and directly from Latin monitionem (nominative monitio) "warning, admonition, reminding," noun of action from past-participle stem of monere "to admonish, warn, advise," from PIE *moneie- "to make think of, remind," suffixed (causative) form of root *men- (1) "to think." With specific meanings in civil and ecclesiastical law.

monitor (n.)

1540s, "senior pupil at a school charged with keeping order, etc.," from Latin monitor "one who reminds, admonishes, or checks," also "an overseer, instructor, guide, teacher," agent noun from monere "to remind, bring to (one's) recollection, tell (of); admonish, advise, warn, instruct, teach," from PIE *moneie- "to make think of, remind" (source also of Sanskrit manayati "to honor, respect," Old Avestan manaiia- "making think"), suffixed (causative) form of root *men- (1) "to think" (source also of Latin memini "I remember, I am mindful of," mens "mind") The notion is "one who or that which warns of faults or informs of duties."

The type of lizard (1826) was so called because it is fabled to give warning to man of Nile crocodiles. Meaning "squat, slow-moving type of ironclad warship" (1862) is from the name of the first vessel of this design, chosen by the inventor, Swedish-born U.S. engineer John Ericsson (1803-1889), because it was meant to "admonish" the Confederate leaders in the U.S. Civil War.

Broadcasting sense of "a device to continuously check on the technical quality of a transmission" (1931) led to special sense of "a TV screen displaying the picture from a particular camera."

monitor (v.)

1924, "to check for quality" (originally especially of radio signals), from monitor (n.). General sense of "observe, keep under review" is from 1944. Keats used it (1818) as "to guide." Related: Monitored; monitoring.

monitory (adj.)

"giving admonition, conveying a warning," late 15c., from Latin monitorius "admonishing," from monitus, past participle of monere "to admonish, warn, advise," from PIE *moneie- "to make think of, remind," suffixed (causative) form of root *men- (1) "to think."

monk (n.)

"member of a community or fraternity of men formed for the practice of religious devotions or duties and bound by certain vows," Old English munuc (used also of women), from Proto-Germanic *muniko- (source also of Old Frisian munek, Middle Dutch monic, Old High German munih, German Mönch), an early borrowing from Vulgar Latin *monicus (source of French moine, Spanish monje, Italian monaco), from Late Latin monachus "monk," originally "religious hermit," from Ecclesiastical Greek monakhos "monk," noun use of a classical Greek adjective meaning "solitary," from monos "alone" (from PIE root *men- (4) "small, isolated"). The original monks in Church history were men who retired from the world for religious meditation and the practice of religious duties in solitude. For substitution of -o- for -u-, see come.

monkey (n.)

1520s, also monkie, munkie, munkye, etc., not found in Middle English (where ape was the usual word); of uncertain origin, but likely from an unrecorded Middle Low German *moneke or Middle Dutch *monnekijn, a colloquial word for "monkey," originally a diminutive of some Romanic word, compare French monne (16c.); Middle Italian monnicchio, from Old Italian monna; Spanish mona "ape, monkey." In a 1498 Low German version of the popular medieval beast story Roman de Renart ("Reynard the Fox"), Moneke is the name given to the son of Martin the Ape; transmission of the word to English might have been via itinerant entertainers from the German states.

The Old French form of the name is Monequin (recorded as Monnekin in a 14c. version from Hainault), which could be a diminutive of some personal name, or it could be from the general Romanic word, which may be ultimately from Arabic maimun "monkey," literally "auspicious," a euphemistic usage because the sight of apes was held by the Arabs to be unlucky [Klein]. The word would have been influenced in Italian by folk etymology from monna "woman," a contraction of ma donna "my lady."

In general, any one of the primates except man and lemurs; in more restricted use, "an anthropoid ape or baboon;" but popularly used especially of the long-tailed species often kept as pets. Monkey has been used affectionately or in pretended disapproval of a child since c. 1600. As the name of a type of modern popular dance, it is attested from 1964.

Monkey suit is from 1876 as a type of child's suit; by 1918 as slang for "fancy dress clothes or uniform." To make a monkey of "make a fool of" is attested from 1851. To have a monkey on one's back "be addicted" is 1930s narcotics slang, though the same phrase in the 1860s meant "to be angry." There is a story in the Sinbad cycle about a tormenting ape-like creature that mounts a man's shoulders and won't get off, which may be the root of the term. In 1890s British slang, to have a monkey up the chimney meant "to have a mortgage on one's house." The Japanese three wise monkeys ("see no evil," etc.) are attested in English by 1891.

monkey (v.)

1859, "to mock, mimic" (as a monkey does), from monkey (n.). Meaning "play foolish tricks" is from 1881. To monkey (with) "act in an idle or meddlesome manner" is by 1884. Related: Monkeyed; monkeying.

monkey-bread (n.)

"fruit of the baobab tree," 1789, from monkey (n.) + bread (n.).

monkey-shines (n.)

also monkeyshines, "monkeyish behavior, tricks, pranks, antics," U.S. slang, 1832 (in the "Jim Crow" song), from monkey (n.) + shine (n.) "a caper, trick" (1835), from an American English slang sense perhaps related to the expression cut a shine "make a fine impression" (1819); see slang senses under shine (n.). For sense of the whole word, compare Old French singerie "disreputable behavior," from singe "monkey, ape."

Also compare monkey business "foolish or deceitful conduct," attested by 1858; one early source from England describes it as a "native Indian term," but the source might be that alluded to in, among other places, this contemporary account given by a professional strongman:

monkey-wrench (n.)

old style of wrench with a jaw adjustable by a screw mechanism on the handle, 1841, from monkey (n.) + wrench (n.). Monkey was used in 19c. especially by sailors, as a modifier for various types of small equipment made for specific work (monkey-block, monkey-boat, monkey-spar, etc.), and the same notion probably is behind the name of the tool. The figurative sense of "something that obstructs operations" is from the notion of one getting jammed in the gears of machinery (compare English spanner in the works).

monkish (adj.)

1540s, "pertaining to a monk;" 1570s, "resembling or characteristic of a monk," from monk (n.) + -ish. Related: Monkishly; monkishness.

monkshood (n.)

also monk's-hood, plant of the genus Aconitum, 1570s, from monk (n.) + hood (n.1). So called for the shape of the flowers.

The constellation below the Twins and the Crab is recorded by this name in English by 1797. Probably it owes its origin to Flemish cartographer Petrus Plancius in the 1590s.

monochrome (n.)

1660s, "painting or drawing done in different tints of a single color," from Latinized form of Greek monokhrōmos, also monokhrōmatos, "of a single color," from monos "single, alone" (from PIE root *men- (4) "small, isolated") + khrōma (genitive khrōmatos) "color, complexion, skin" (see chroma). As an adjective from 1849. Photographic sense is recorded from 1940.

monochromatic (adj.)

"of one color, consisting of light of one wavelength," 1807, from mono- + chromatic, or from monochrome. Perhaps based on French monochromatique or Greek monokhrōmatos "of one color." Related: Monochromatically (1784).
