mid-12c., "the exercise of authority in vindication of right by assigning reward or punishment;" also "quality of being fair and just; moral soundness and conformity to truth," from Old French justice "justice, legal rights, jurisdiction" (11c.), from Latin iustitia "righteousness, equity," from iustus "upright, just" (see just (adj.)).

Justice is the end of government. It is the end of civil society. It ever has been and ever will be pursued until it be obtained, or until liberty be lost in the pursuit. ["The Federalist," No. 51]

Meaning "right order, equity, the rewarding to everyone of that which is his due" in English is from late 14c. The Old French word had widespread senses including also "uprightness, equity, vindication of right, court of justice, judge." To the Greek philosophers (Plato, Aristotle) the notion was of each thing in its proper sphere or serving its proper purpose; inequality of aptitudes and outcomes was implied.

In English c. 1400-1700 sometimes also with a vindictive sense "infliction of punishment, legal vengeance." As a title for a judicial officer, c. 1200. Justice of the peace is attested from early 14c. To do justice to (someone or something) "deal with as is right or fitting" is from 1670s. In the Mercian hymns, Latin iustitia is glossed by Old English rehtwisnisse.

mid-12c., "authorized representative of the Pope," from Old French legat and directly from Latin legatus "ambassador, envoy," originally "provided with a commission," past participle of legare "send as a deputy, send with a commission, charge, bequeath," possibly literally "engage by contract" and related to lex (genitive legis) "contract, law," from PIE root *leg- (1) "to collect, gather." General sense of "ambassador, delegate, messenger of a state or authority" is from late 14c. in English. Related: Legator; legatee; legatine.

"to be pleased, desire" (intransitive), a sense now archaic, mid-12c., lusten, listen "to please, desire," from Old English lystan "to please, cause pleasure or desire, provoke longing," from Proto-Germanic *lustjan (source also of Old Saxon lustian, Dutch lusten "to like, fancy," Old High German lusten, German lüsten, Old Norse lysta "desire, wish, have a fancy"), from *lustuz-, from PIE root *las- "to be eager, wanton, or unruly" (see lust (n.)). Related: Listed; listing.

"the Roman god Mercury," herald and ambassador of his father, Jupiter, mid-12c., Mercurie, from Latin Mercurius "Mercury," originally a god of tradesmen and thieves, from merx "merchandise" (see market (n.)); or perhaps [Klein, Tucker] from Etruscan and influenced by merx. De Vaan thinks it possible the whole stem *merk- was borrowed and the god-name with it.

Mercury later was identified with Greek Hermes and still later with Germanic Woden. From his role as a messenger and conveyor of information, since mid-17c. Mercury has been a common name for a newspaper. 

The planet closest to the sun was so called in classical Latin (c. 1300 in English). A hypothetical inhabitant of the planet was a Mercurean (1855) or a Mercurian (1755). For the metallic element, see mercury.

In U.S. numismatics, the Mercury-head dime (so called by 1941) was in circulation from 1916; properly it is the female head of Liberty, in her characteristic cap, here winged to symbolize freedom of thought. But the resemblance to Mercury was noted in coin circles at once, and the coin design sometimes was popularly mistaken as the head of Mercury, Roman god of making money and thieving, in his winged hat. It was so-called in 1933 in newspaper articles calling attention to the fasces on the reverse. The coin is more correctly the Winged Liberty-head dime (simple Liberty-head dime being a designation of the previous design). The design was replaced in 1946, which made it necessary for it to have an agreed-upon specifying name.

There's the four-year-old who counted out 20 cents with the remark: "A boy dime and a girl dime."

Translated, this means a Roosevelt dime and one classified by coin books as the "new Mercury head" dime.

mid-12c., "a wondrous work of God," from Old French miracle (11c.) "miracle, story of a miracle, miracle play," from Latin miraculum "object of wonder" (in Church Latin, "marvelous event caused by God"), from mirari "to wonder at, marvel, be astonished," figuratively "to regard, esteem," from mirus "wonderful, astonishing, amazing," earlier *smeiros, from PIE *smei- "to smile, laugh" (source also of Sanskrit smerah "smiling," Greek meidan "to smile," Old Church Slavonic smejo "to laugh;" see smile (v.)). The Latin word is the source of Spanish milagro, Italian miracolo. 

From mid-13c. as "something that excites wonder or astonishment, extraordinary or remarkable feat," without regard to divinity or supernatural power. It replaced Old English wundortacen, wundorweorc. The Greek words rendered as miracle in the English bibles were semeion "sign," teras "wonder," and dynamis "power," which in the Vulgate were translated respectively as signum, prodigium, and virtus.

Miracle-drug is by 1939 (in reference to sulfanilamide). Miracle-worker "a thaumaturge" is from 1560s (Middle English had mircleour, early 15c.). Miracle-play "medieval dramatic representation of the life of Christ or a saint or other sacred subjects" is by 1744 (miraclis pleynge is from c. 1400). The condiment Miracle Whip was introduced 1933 by Kraft Foods; apparently the name was first given to the patented machine that made it.

mid-12c., multeplien, "to cause to become many, cause to increase in number or quantity," from Old French multiplier, mouteplier (12c.) "increase, get bigger; flourish; breed; extend, enrich," from Latin multiplicare "to increase," from multiplex (genitive multiplicis) "having many folds, many times as great in number," from combining form of multus "much, many" (see multi-) + -plex "-fold," from PIE root *plek- "to plait."

Intransitive sense of "grow or increase in number or extent" (especially "to have children, produce offspring") is from mid-14c. Mathematical sense "perform the process of multiplication" is attested from late 14c. Related: Multiplied; multiplying.

mid-12c., non "midday," in exact use, "12 o'clock p.m.," also "midday meal," from Old English non "3 o'clock p.m., the ninth hour from sunrise," also "the canonical hour of nones," from Latin nona hora "ninth hour" of daylight, by Roman and ecclesiastical reckoning about 3 p.m., from nona, fem. singular of nonus "ninth," contracted from *novenos, from novem "nine" (see nine).

The sense shift from "3 p.m." to "12 p.m." began during 12c., and various reasons are given for it, such as unreliability of medieval time-keeping devices and the seasonal elasticity of the hours of daylight in northern regions. In monasteries and on holy days, fasting ended at nones, which perhaps offered another incentive to nudge it up the clock. Or perhaps the sense shift was based on an advance in the customary time of the (secular) midday meal. Whatever the cause, the meaning change from "ninth hour" to "sixth hour" seems to have been complete by 14c. (the same evolution is in Dutch noen).

From 17c. to 19c., noon sometimes also meant "midnight" (the noon of the night).

surname, literally "the keeper of a park," mid-12c.; see park (n.).  

mid-12c., pes, "freedom from civil disorder, internal peace of a nation," from Anglo-French pes, Old French pais "peace, reconciliation, silence, permission" (11c., Modern French paix), from Latin pacem (nominative pax) "compact, agreement, treaty of peace, tranquility, absence of war" (source of Provençal patz, Spanish paz, Italian pace), from PIE root *pag- "to fasten" (which is the source also of Latin pacisci "to covenant or agree;" see pact), perhaps on the notion of "a binding together" by treaty or agreement.

It replaced Old English frið, also sibb, which also meant "happiness." The modern spelling is from 1500s, reflecting vowel shift.

It is attested from mid-13c. as "friendly relations between people." The sense of "spiritual peace of the heart, soul or conscience, freedom from disturbance by the passions" (as in peace of mind) is from c. 1200. The sense of "state of quiet or tranquility" is by 1300, as is the meaning "absence or cessation of war or hostility." Specifically as "treaty or agreement made between conflicting parties to refrain from further hostilities," c. 1400.

Used in various greetings from c. 1300, from Biblical Latin pax, Greek eirēnē, which translators took to render Hebrew shalom, properly "safety, welfare, prosperity." As a type of hybrid tea rose (developed 1939 in France by François Meilland), so called from 1944.

The Native American peace pipe, supposedly smoked as the accompaniment of a treaty, is recorded by 1760. Peace-officer "civil officer whose duty it is to preserve public peace" is attested from 1714. Peace offering "offering that procures peace or reconciliation, satisfaction offered to an offended person" is from 1530s. Phrase peace with honor dates to 1607 (in "Coriolanus"). The U.S. Peace Corps was set up March 1, 1962. Peace sign, in reference to both the hand gesture and the graphic, is attested from 1968.

mid-12c., pekking, "the pecking of birds," verbal noun from peck (v.). As a description of a pattern of behavior among hens, pecking order (1928) translates German hackliste (T.J. Schjelderuo-Ebbe, 1922); the transferred sense of "human hierarchy based on rank or status" is by 1955.
