Named for English philosopher William of Ockham or Occam (c. 1285-c. 1349), who expressed it with Entia non sunt multiplicanda praeter ncccssitatem.
So called after William of Occam (died about 1349): but, as a historical fact, Occam does not make much use of this principle, which belongs rather to the contemporary nominalist William Durand de St. Pourçain (died 1332). [Century Dictionary]
octave (n.) Look up octave at Dictionary.com
c. 1300, utaves (plural, via Anglo-French from popular Old French form oitieve, otaves), reformed in early 15c., from Medieval Latin octava, from Latin octava dies "eighth day," fem. of octavus "eighth," from octo (see eight). Originally "period of eight days after a festival," also "eighth day after a festival" (counting both days, by inclusive reckoning, thus if the festival was on a Sunday, the octaves would be the following Sunday).

by c. 1200 as an emphatic form of Old English of (see of), employed in the adverbial use of that word. The prepositional meaning "away from" and the adjectival sense of "farther" were not firmly fixed in this variant until 17c., but once they were they left the original of with the transferred and weakened senses of the word. Meaning "not working" is from 1861. Off the cuff (1938) is from the notion of speaking from notes written in haste on one's shirt cuffs. Off the rack (adj.) is from 1963; off the record is from 1933; off the wall "crazy" is 1968, probably from the notion of a lunatic "bouncing off the walls" or else in reference to carom shots in squash, handball, etc.
vacation (n.) Look up vacation at Dictionary.com
late 14c., "freedom from obligations, leisure, release" (from some activity or occupation), from Old French vacacion "vacancy, vacant position" (14c.) and directly from Latin vacationem (nominative vacatio) "leisure, freedom, exemption, a being free from duty, immunity earned by service," noun of state from past participle stem of vacare "be empty, free, or at leisure" (see vain).

early 14c. (late 12c. in surnames), "brave, courageous, intrepid in danger," from Anglo-French vaylant, and Old French vaillant "stalwart, brave," present participle adjective from valoir "be worthy," originally "be strong," from Latin valere "be strong, be well, be worth, have power, be able, be in health," from PIE root *wal- "be strong" (source also of Old English wealdan "to rule," Old High German -walt, -wald "power" (in personal names), Old Norse valdr "ruler," Old Church Slavonic vlasti "to rule over," Lithuanian valdyti "to have power," Celtic *walos- "ruler," Old Irish flaith "dominion," Welsh gallu "to be able"). As a noun, "valiant person," from c. 1600. Related: Valiantly.
tar (n.1) Look up tar at Dictionary.com
a viscous liquid, Old English teoru, teru "tar, bitumen, resin, gum," literally "the pitch of (certain kinds of) trees," from Proto-Germanic *terwo- (source also of Old Norse tjara, Old Frisian tera, Middle Dutch tar, Dutch teer, German Teer), probably a derivation of *trewo-, from PIE *derw-, variant of root *deru-, *dreu- in its sense "wood, tree" (see tree (n.)).

Tar baby "a sticky problem," also a derogatory term for "black person," is from an 1881 "Uncle Remus" story by Joel Chandler Harris. Tarheel for "North Carolina resident" first recorded 1864, probably from the gummy resin of pine woods. Tar water, an infusion of tar in cold water, was popular as a remedy from c. 1740 through late 18c.
tan (v.) Look up tan at Dictionary.com
late Old English tannian "to convert hide into leather" (by steeping it in tannin), from Medieval Latin tannare "tan, dye a tawny color" (c.900), from tannum "crushed oak bark," used in tanning leather, probably from a Celtic source (such as Breton tann "oak tree"). The meaning "make brown by exposure to the sun" (as tanning does to hides) first recorded 1520s; intransitive sense also from 1520s. Of persons, not considered an attractive feature until 20c.; in Shakespeare, "to deprive of the freshness and beauty of youth" (Sonnet CXV). As an adjective from 1620s. To tan (someone's) hide in the figurative sense is from 1660s. Related: Tanned; tanning. German Tanne "fir tree" (as in Tannenbaum) might be a transferred meaning from the same Celtic source.
quarterstaff (n.) Look up quarterstaff at Dictionary.com
also quarter-staff, 1540s (quarter-stroke "stroke with a quarterstaff" is attested from early 15c.), stout pole, six to eight feet long (six-and-a-half sometimes is given as the standard length), tipped with iron, formerly a weapon used by the English peasantry. From staff (n.); the quarter is of uncertain signification. According to one theory, favored by fencing manuals, etc., it likely is in reference to operation of the weapon:
It was grasped by one hand in the middle, and by the other between the middle and the end. In the attack the latter hand shifted from one quarter of the staff to the other, giving the weapon a rapid circular motion, which brought the ends on the adversary at unexpected points. [Century Dictionary]
Linguists tend to prefer an explanation from woodcutting, perhaps a reference to a cut of lumber known as a quarter, but contemporary evidence is wanting for either conjecture.
quash (v.) Look up quash at Dictionary.com
"to make void, annul," early 14c., from Old French quasser, casser "to annul, declare void," and directly from Medieval Latin quassare, alteration of Late Latin cassare, from cassus "null, void, empty" (see caste (n.)).

Meaning "to break, crush," is early 14c., from Old French quasser, casser "to break, smash, injure, harm, weaken," from Latin quassare "to shatter," frequentative of quatere (past participle quassus) "to shake," from PIE root *kwet- "to shake" (source also of Greek passein "to sprinkle," Lithuanian kuteti "to shake up," Old Saxon skuddian "to move violently," German schütteln "to shake," Old English scudan "to hasten").

The words have influenced each other in form and sense since Medieval Latin and now are somewhat grown together. Related: Quashed; quashing.
pantheism (n.) Look up pantheism at Dictionary.com
"belief that God and the universe are identical," from pantheist (n.), which was coined (1705) by Irish deist John Toland (1670-1722), from Greek pan- "all" (see pan-) + theos "god" (see theo-).

Toland's word was borrowed into French, which from it formed panthéisme (1712) which returned to English as pantheism "the doctrine that all is god" in 1732 (no evidence that Toland used pantheism).

Greek pantheios meant "common to all gods" (see pantheon). Other words used at various times for similar notions include panentheism, "philosophy founded on the notion that all things are in God" (1874), from German (1828), coined by Karl Christian Friedrich Krause (1781-1832).
raspberry (n.) Look up raspberry at Dictionary.com
1620s, earlier raspis berry (1540s), possibly from raspise "a sweet rose-colored wine" (mid-15c.), from Anglo-Latin vinum raspeys, origin uncertain, as is the connection between this and Old French raspe, Medieval Latin raspecia, raspeium, also meaning "raspberry." One suggestion is via Old Walloon raspoie "thicket," of Germanic origin. Klein suggests it is via the French word, from a Germanic source akin to English rasp (v.), with an original sense of "rough berry," based on appearance.

A native plant of Europe and Asiatic Russia, the name was applied to a similar vine in North America. Meaning "rude sound" (1890) is shortening of raspberry tart, rhyming slang for fart.
razzle-dazzle (n.) Look up razzle-dazzle at Dictionary.com
1886, American English slang, varied reduplication of dazzle (q.v.).
My confrère, The Chevalier, last month gave a new name to the scarfs of disjointed pattern when he called them the razzle-dazzle. The name was evidently a hit of the most patent character, for in several avenue and Broadway stores the clerks have thrown out a display of broken figures before me and explained that the ruling style at present was the razzle-dazzle, and the word seems to have been equally effective with the public, for when it is quoted by the live salesman, the customer, I am told is at once interested and caught by it. ["Clothier and Furnisher" magazine, Jan. 1889]
Meaning "state of confusion" is from 1889.
veep (n.) Look up veep at Dictionary.com
1949, American English, apparently coined from V.P., abbreviation of vice president, perhaps modeled on jeep, which was then in vogue. Introduced by Alben W. Barkley (1877-1956), Harry Truman's vice president. According to the "Saturday Evening Post," "his grandchildren, finding Vice-President too long, call him that." The magazines quickly picked it up, especially when the 71-year-old Barkley married a 38-year-old widow (dubbed the Veepess).
Barkley says word "Veep" is not copyrighted, and any vice president who wants to can use it. But he hopes not many will. [U.S. Department of State wireless bulletin, 1949]
"Time," tongue in cheek, suggested the president should be Peep, the Secretary of State Steep, and the Secretary of Labor Sleep.
rage (n.) Look up rage at Dictionary.com
c. 1300, "madness, insanity; fit of frenzy; anger, wrath; fierceness in battle; violence of storm, fire, etc.," from Old French rage, raige "spirit, passion, rage, fury, madness" (11c.), from Medieval Latin rabia, from Latin rabies "madness, rage, fury," related to rabere "be mad, rave" (compare rabies, which originally had this sense), from PIE *rebh- "violent, impetuous" (source also of Old English rabbian "to rage"). Similarly, Welsh (cynddaredd) and Breton (kounnar) words for "rage, fury" originally meant "hydrophobia" and are compounds based on the word for "dog" (Welsh ci, plural cwn; Breton ki). In 15c.-16c. it also could mean "rabies." The rage "fashion, vogue" dates from 1785.
palace (n.) Look up palace at Dictionary.com
early 13c., "official residence of an emperor, king, archbishop, etc.," from Old French palais "palace, court," from Medieval Latin palacium "a palace" (source of Spanish palacio, Italian palazzo), from Latin palatium "the Palatine hill," in plural, "a palace," from Mons Palatinus "the Palatine Hill," one of the seven hills of ancient Rome, where Augustus Caesar's house stood (the original "palace"), later the site of the splendid residence built by Nero. In English, the general sense of "splendid dwelling place" is from late 14c.

The hill name probably is ultimately from palus "stake," on the notion of "enclosure." Another guess is that it is from Etruscan and connected with Pales, supposed name of an Italic goddess of shepherds and cattle.
gentry (n.) Look up gentry at Dictionary.com
c. 1300, "nobility of rank or birth;" mid-14c., "a fashion or custom of the nobility;" late 14c., "nobility of character," from Old French genterie, genterise, variant of gentelise "noble birth, aristocracy; courage, honor; kindness, gentleness," from gentil "high-born, noble, of good family" (see gentle). Meaning "noble persons, the class of well-born and well-bred people" is from 1520s in English, later often in England referring to the upper middle class, persons of means and leisure but below the nobility. Earlier in both senses was gentrice (c. 1200 as "nobility of character," late 14c. as "noble persons"), and gentry in early use also might have been regarded as a singular of that. In Anglo-Irish, gentry was a name for "the fairies" (1880), and gentle could mean "enchanted" (1823).
gerrymander (v.) Look up gerrymander at Dictionary.com
1812, "arrange political divisions in disregard of natural boundaries so as to give one party an advantage in elections," also from 1812 as a noun, American English, from name of Elbridge Gerry + (sala)mander. Gerry, governor of Massachusetts, was lampooned when his party redistricted the state in a blatant bid to preserve an Antifederalist majority. One sprawling Essex County district resembled a salamander, and a newspaper editor dubbed it the Gerrymander. Related: Gerrymandered; gerrymandering.
[T]he division of this county into districts has given an opportunity for a Caracatura stamped at Boston and freely circulated here called the Gerrymander. The towns as they lie are disposed as parts of a monster whose feet and claws are Salem and Marblehead. It is one of those political tricks which have success as far as they go. [William Bentley, diary, April 2, 1812]
jog (v.) Look up jog at Dictionary.com
1540s, "to shake up and down," perhaps altered from Middle English shoggen "to shake, jolt, move with a jerk" (late 14c.), a word of uncertain origin. Meanings "touch or push slightly," "stir up or stimulate by hint or push," and "walk or ride with a jolting pace" all are from 16c.

The modern sense in reference to running as training mostly dates from 1948; at first a regimen for athletes, it became a popular fad c. 1967. Perhaps this sense is extended from its use in horsemanship.
Jogging. The act of exercising, or working a horse to keep him in condition, or to prepare him for a race. There is no development in jogging, and it is wholly a preliminary exercise to bring the muscular organization to the point of sustained, determined action. [Samuel L. Boardman, "Handbook of the Turf," New York, 1910]
Related: Jogged; jogging.
josh (v.) Look up josh at Dictionary.com
"to make fun of, to banter," 1845 (intransitive), 1852 (transitive), American English; according to "Dictionary of American Slang," the earliest example is capitalized, hence it is probably from the familiar version of the proper name Joshua. Perhaps it was taken as a typical name of an old farmer.

If those dates are correct, the word was in use earlier than the career of U.S. humorist Josh Billings, pseudonym of Henry Wheeler Shaw (1818-1885), who did not begin to write and lecture until 1860; but his popularity after 1869 may have influence that of the word, or even re-coined it, as it does not seem to have been much in print before 1875.
About the most originality that any writer can hope to achieve honestly is to steal with good judgment. ["Josh Billings"]
Related: Joshed; joshing.
journal (n.) Look up journal at Dictionary.com
mid-14c., "book of church services," from Anglo-French jurnal, from Old French jornel, "a day; time; a day's travel or work" (12c., Modern French journal), properly "that which takes place daily," noun use of adjective meaning "daily, of the day," from Late Latin diurnalis "daily" (see diurnal).

The meaning "book for inventories and daily accounts" is from late 15c. in English (14c. in French); that of "personal diary" is c. 1600, also from a sense developed in French. Meaning "daily publication" is from 1728. Classical Latin used diurnus for "of the day, by day," and also as a noun, "account-book, day-book."

Initial -d- in Latin usually remains in French, but according to Brachet, when it is followed by an -iu-, the -i- becomes consonantized as a -j- "and eventually ejects the d." He also cites jusque from de-usque.
judge (v.) Look up judge at Dictionary.com
c. 1200, iugen, "examine, appraise, make a diagnosis;" c. 1300, "to form an opinion about; inflict penalty upon, punish; try (someone) and pronounce sentence," also intransitive, "make a decision, decide, think, suppose;" from Anglo-French juger, Old French jugier "to judge, pronounce judgment; pass an opinion on" (10c., Modern French juger), from Latin iudicare "to judge, to examine officially; form an opinion upon; pronounce judgment," from iudicem (nominative iudex) "a judge," a compound of ius "right, law" (see just (adj.)) + root of dicere "to say" (see diction).

Related: Judged; judging. Spelling with -dg- emerged mid-15c. The Old English word was deman (see doom (n.)). The Latin word also is the source of Spanish juzgar, Italian giudicare.
junior (adj.) Look up junior at Dictionary.com
late 13c., "younger, not as old as another," from Latin iunior "younger, more young," comparative of iuvenis "young; a young man," from PIE root *yeu- "vital force, youthful vigor" (see young (adj.)). Used after a person's name to mean "the younger of two" from late 13c. Abbreviation Jr. is attested from 1620s. Meaning "of lesser standing, more recent" is from 1766. That of "meant for younger people, of smaller size" is from 1860. Junior miss "young teenage girl" is from 1907. In U.S. colleges, "pertaining to the third-year." Junior college first attested 1896; junior high school is from 1909.
The junior high school is rapidly becoming the people's high school. The percentage of pupils completing the ninth year is constantly rising where junior high schools have been established. [Anne Laura McGregor, "Supervised Study in English for Junior High School Grades," New York, 1921]
juniper (n.) Look up juniper at Dictionary.com
coniferous evergreen shrub of northern regions, late 14c., gynypre, etc. (later altered to conform to Latin), from Latin iuniperus "the juniper tree" (source of Old French genevre, French genièvre, Spanish enebro, Portuguese zimbro, Italian ginepro, and, via Old French, Middle Dutch genever), a word of uncertain origin.

Perhaps it is related to iunco "reed," but there are phonetic difficulties. Watkins has it from PIE *yoini-paros "bearing juniper berries," from *yoi-ni- "juniper berry," perhaps from a non-IE language, + *-paro "producing." Applied to various North American species from 1748. In the English Bible (late 14c.), it renders Hebrew rethem, the name of a white-flowered shrub unrelated to the European evergreen, as the Latin word does in the Vulgate.
hat (n.) Look up hat at Dictionary.com
Old English hæt "hat, head covering" (variously glossing Latin pileus, galerus, mitra, tiara), from Proto-Germanic *hattuz "hood, cowl" (source also of Frisian hat, Old Norse hattr, höttr "a hood or cowl"), from PIE root *kadh- "cover, protect" (source also of Lithuanian kudas "tuft or crest of a bird," Latin cassis "helmet"). To throw one's hat in the ring was originally (1847) to take up a challenge in prize-fighting. To eat one's hat (1770), expressing what one will do if something he considers a sure thing turns out not to be, is said to have been originally eat Old Rowley's [Charles II's] hat.
hazard (n.) Look up hazard at Dictionary.com
c. 1300, name of a game at dice, from Old French hasard, hasart "game of chance played with dice," also "a throw of six in dice" (12c.), of uncertain origin. Possibly from Spanish azar "an unfortunate card or throw at dice," which is said to be from Arabic az-zahr (for al-zahr) "the die." But this is doubtful because of the absence of zahr in classical Arabic dictionaries. Klein suggests Arabic yasara "he played at dice;" Arabic -s- regularly becomes Spanish -z-. The -d was added in French through confusion with the native suffix -ard. Sense evolved in French to "chances in gambling," then "chances in life." In English, sense of "chance of loss or harm, risk" first recorded 1540s.
hearse (n.) Look up hearse at Dictionary.com
c. 1300 (late 13c. in Anglo-Latin), "flat framework for candles, hung over a coffin," from Old French herse, formerly herce "large rake for breaking up soil, harrow; portcullis," also "large chandelier in a church," from Medieval Latin hercia, from Latin hirpicem (nominative hirpex) "harrow," a rustic word, from Oscan hirpus "wolf," supposedly in allusion to its teeth. Or the Oscan word may be related to Latin hirsutus "shaggy, bristly."

The funeral display is so called because it resembled a harrow (hearse in its sense of "portcullis" is not attested in English before 15c.). Sense extended to other temporary frameworks built over dead people, then to "vehicle for carrying a dead person to the grave," a sense first recorded 1640s. For spelling, see head (n.).
heaven (n.) Look up heaven at Dictionary.com
Old English heofon "home of God," earlier "the visible sky, firmament," probably from Proto-Germanic *hibin-, dissimilated from *himin- (cognates Low German heben, Old Norse himinn, Gothic himins, Old Frisian himul, Dutch hemel, German Himmel "heaven, sky"), which is of uncertain origin. Perhaps literally "a covering," from a PIE root *kem- "to cover" (also proposed as the source of chemise). Watkins derives it elaborately from PIE *ak- "sharp" via *akman- "stone, sharp stone," then "stony vault of heaven."

From late 14c. as "a heavenly place; a state of bliss." Plural use in sense of "sky" probably is from Ptolemaic theory of space as composed of many spheres, but it also formerly was used in the same sense as the singular in Biblical language, as a translation of Hebrew plural shamayim. Heaven-sent (adj.) attested from 1640s.
demi-monde (n.) Look up demi-monde at Dictionary.com
also demimonde, 1855, from French demi-monde "so-so society," literally "half-world," from demi- "half" + monde, from Latin mundus "world" (see mundane).

Popularized by its use as title of a comedy by Alexandre Dumas fils (1824-1895). Dumas' Demi-Monde "is the link between good and bad society ... the world of compromised women, a social limbo, the inmates of which ... are perpetually struggling to emerge into the paradise of honest and respectable ladies" ["Fraser's Magazine," 1855]. Not properly used of courtesans. Compare 18th-century English demi-rep (1749, the second element short for reputation), defined as "a woman that intrigues with every man she likes, under the name and appearance of virtue ... in short, whom every body knows to be what no body calls her" [Fielding].
lavender (n.) Look up lavender at Dictionary.com
"fragrant plant of the mint family," c. 1300, from Anglo-French lavendre, Old French lavendre "the lavender plant," from Medieval Latin lavendula "lavender" (10c.), perhaps from Latin lividus "bluish, livid." If so, it probably was associated with French lavande, Italian lavanda "a washing" (from Latin lavare "to wash;" see lave) because it was used to scent washed fabrics and as a bath perfume.

The adjective meaning "of a pale purple color, of the color of lavender flowers" is from 1840; as a noun in the color sense from 1882. An identical Middle English word meant "laundress, washerwoman;" also, apparently, "prostitute, whore; camp follower" and is attested as a surname from early 13c.
lax (adj.) Look up lax at Dictionary.com
c. 1400, "loose" (in reference to bowels), from Latin laxus "wide, spacious, roomy," figuratively "loose, free, wide" (also used of indulgent rule and low prices), from PIE *lag-so-, suffixed form of root *(s)lēg- "to be slack, be languid" (source also of Greek legein "to leave off, stop," lagos "hare," literally "with drooping ears," lagnos "lustful, lascivious," lagaros "slack, hollow, shrunken;" Latin languere "to be faint, weary," languidis "faint, weak, dull, sluggish, languid").

In English, of rules, discipline, etc., from mid-15c. Related: Laxly; laxness. A transposed Vulgar Latin form yielded Old French lasche, French lâche. The laxists, though they formed no avowed school, were nonetheless condemned by Innocent XI in 1679.
infernal (adj.) Look up infernal at Dictionary.com
late 14c., "of or pertaining to the underworld," (ancient Tartarus, the sunless abode of the dead, or the Christian Hell), from Old French enfernal, infernal "of Hell, hellish" (12c.), from Late Latin infernalis "of or belonging to the lower regions," from infernus "hell" (Ambrose), in classical Latin "the lower (world)," noun use of infernus "lower, lying beneath, underground, of the lower regions," from infra "below" (see infra-).

Pluto was infernus rex, and Latin inferi meant "the inhabitants of the infernal regions, the dead." Association of the word with fire and heat is via the Christian conception of Hell. Meaning "devilish, hateful" is from early 15c.; meaning "suitable for or appropriate to Hell" is from c. 1600. As a name of Hell, or a word for things which resemble it, the Italian form inferno has been used in English since 1834, via Dante. Related: Infernally.
incarceration (n.) Look up incarceration at Dictionary.com
"fact of being imprisoned," 1530s, from Medieval Latin incarcerationem (nominative incarceratio), noun of action from past participle stem of incarcerare "to imprison," from in- "in" (see in- (2)) + carcer "prison, an enclosed space," from Proto-Italic *kar-kr(o)-, of uncertain origin.
It seems best to connect carcer with other IE words for 'circle, round object', such as [Latin] curvus, [Greek] κιρκος 'ring', [Old Norse] hringr, although not all of these have a good IE etymology. The reduplication in Latin carcer could be iconic; thus, the original meaning would have been 'enclosure'. [de Vaan]
The word appears earlier in English in an obsolete medical sense of "retention of pus" (early 15c.).
glasnost (n.) Look up glasnost at Dictionary.com
1972 (in reference to a letter of 1969 by Solzhenitsyn), from Russian glasnost "openness to public scrutiny," literally "publicity, fact of being public," ultimately from Old Church Slavonic glasu "voice," from PIE *gal-so-, from root *gal- (2) "to call, shout" (see call (v.)). First used in a socio-political sense by Lenin; popularized in English after Mikhail Gorbachev used it prominently in a speech of March 11, 1985, accepting the post of general secretary of the CPSU.
The Soviets, it seems, have rediscovered the value of Lenin's dictum that "glasnost," the Russian word for openness or publicity, is a desirable form of conduct. [New York Times news service article, March 1981]
harbinger (n.) Look up harbinger at Dictionary.com
late 15c., herbengar "one sent ahead to arrange lodgings" (for a monarch, an army, etc.), alteration of Middle English herberger "provider of shelter, innkeeper" (late 12c.), from Old French herbergeor "one who offers lodging, innkeeper," agent noun from herbergier "provide lodging," from herber "lodging, shelter," from Frankish *heriberga "lodging, inn" (cognate with Old Saxon, Old High German heriberga "army shelter"), from Germanic compound *harja-bergaz "shelter, lodgings," which is also the source of harbor (n.). Sense of "forerunner, that which precedes and gives notice of the coming of another" is mid-16c. Intrusive -n- is 15c. (see messenger). As a verb, from 1640s (harbinge "to lodge" is late 15c.).
harness (n.) Look up harness at Dictionary.com
c. 1300, "personal fighting equipment, body armor," also "armor or trappings of a war-horse," from Old French harnois, a noun of broad meaning: "arms, equipment; harness; male genitalia; tackle; household equipment" (12c.), of uncertain origin, perhaps from Old Norse *hernest "provisions for an army," from herr "army" (see harry (v.)) + nest "provisions" (see nostalgia). Non-military sense of "fittings for a beast of burden" is from early 14c. German Harnisch "harness, armor" is the French word, borrowed into Middle High German. The Celtic words are believed to be also from French, as are Spanish arnes, Portuguese arnez, Italian arnese. Prive harness (late 14c.) was a Middle English term for "sex organs."
