climate [climate 词源字典]: climate: [14] The notion underlying climate is of ‘sloping’ or ‘leaning’. It comes, via Old French climat or late Latin clīma (whence English clime [16]), from Greek klīma ‘sloping surface of the earth’, which came ultimately from the same source (the Indo-European base *kli-) as produced English lean. Greek geographers assigned the earth’s surface to various zones according to the angle which their ‘slope’ made with the rays of the sun (originally there were seven of these, ranging from 17 degrees of latitude North to 48 degrees, but later the system was elaborated so that each hemisphere was divided into 24 bands or ‘climates’ of latitude).

This was the sense in which the word passed into Latin, where it broadened out into simply ‘region’, and hence ‘weather associated with a particular area’.
=> ladder, lean[climate etymology, climate origin, 英语词源]
obtuse: obtuse: [16] The etymological meaning of obtuse is ‘beaten down, blunted’. It comes from Latin obtūsus, the past participle of obtundere, a compound verb formed from the prefix ob- ‘against’ and tundere ‘beat’ (source of English contusion and related to toil). The notion of being ‘dulled’ or ‘blunted’ led to its being used for ‘having dulled wits, stupid’, and the idea of bluntness also lies behind its geometrical use for an angle of more than 90 degrees (as contrasted with the ‘sharp’ acute angle).
=> contusion, toil
absolute zero (n.): the idea dates back to 1702 and its general value was guessed to within a few degrees soon thereafter, but not precisely discovered until Lord Kelvin's work in 1848. It was known by many names, such as infinite cold, absolute cold, natural zero of temperature; the term absolute zero was among them by 1806.
anaesthesiology (n.): 1908, from anaesthesia + -ology.
Anesthesiology. This is the new term adopted by the University of Illinois defining "the science that treats of the means and methods of producing in man or animal various degrees of insensibility with or without hypnosis." ["Medical Herald," January, 1912]
Arctic Circle: 1550s, in reference to a celestial circle, a line around the sky which, in any location, bounds the stars which are ever-visible from that latitude (in the Northern Hemisphere, this is focused on the celestial north pole); the concept goes back to the ancient Greeks, for whom this set of constellations included most prominently the two bears (arktoi), hence the name for the circle (see arctic). Of Earth, the circle 66 degrees 32 minutes north of the equator, marking the southern extremity of the polar day, it is recorded from 1620s.
brilliance (n.): 1755, from brilliant + -ance. Figurative sense (of wit, intelligence, etc.) is from 1779. Distinguished from brilliancy in that the latter usually is applied to things measurable in degrees.
cucumber (n.): late 14c., from Old French cocombre (13c., Modern French concombre), from Latin cucumerem (nominative cucumis), perhaps from a pre-Italic Mediterranean language. The Latin word also is the source of Italian cocomero, Spanish cohombro, Portuguese cogombro. Replaced Old English eorþæppla (plural), literally "earth-apples."

Cowcumber was common form 17c.-18c., and that pronunciation lingered into 19c. Planted as a garden vegetable by 1609 by Jamestown colonists. Phrase cool as a cucumber (c. 1732) embodies ancient folk knowledge confirmed by science in 1970: inside of a field cucumber on a warm day is 20 degrees cooler than the air temperature.
degree (n.): early 13c., from Old French degré (12c.) "a step (of a stair), pace, degree (of relationship), academic degree; rank, status, position," said to be from Vulgar Latin *degradus "a step," from Late Latin degredare, from Latin de- "down" (see de-) + gradus "step" (see grade (n.)).

Most modern senses date from Middle English, from notion of a hierarchy of steps. Meaning "a grade of crime" is 1670s; that of "a unit of temperature" is from 1727. The division of the circle into 360 degrees was known in Babylon and Egypt. It is perhaps from the daily motion of the sun through the zodiac in the course of a year.

It is well known that society in the island [Guernsey] is, or perhaps we ought to say, for many years was, divided into two sets, called respectively the Sixties and the Forties, the former composed of the old families and those allied to them, the latter of families of newly-acquired wealth and position. ["The Dublin Review," October 1877]
Roaring Forties are rough parts of the ocean between 40 and 50 degrees latitude.
gradate (v.): "pass by imperceptible degrees," 1753, back-formation from gradation. Related: Gradated; gradating.

in-law (n.): 1894, "anyone of a relationship not natural," abstracted from father-in-law, etc.
The position of the 'in-laws' (a happy phrase which is attributed ... to her Majesty, than whom no one can be better acquainted with the article) is often not very apt to promote happiness. ["Blackwood's Magazine," 1894]
The earliest recorded use of the phrase is in brother-in-law (13c.); the law is Canon Law, which defines degrees of relationship within which marriage is prohibited.
L.L.: contraction of Latin legum "of laws, in degrees;" as in L.L.D., which stands for Legum Doctor "Doctor of Laws." Plural abbreviations in Latin were formed by doubling the letter.
middle (adj.): Old English middel, from West Germanic *middila (cognates: Old Frisian middel, Old Saxon middil, Middle Low German, Dutch middel, Old High German mittil, German mittel), from Proto-Germanic *medjaz (see mid). Middle name attested from 1815; as "one's outstanding characteristic," colloquial, from 1911, American English.
According to Mr. H.A. Hamilton, in his "Quarter Sessions from Queen Elizabeth," the practice of giving children two Christian names was unknown in England before the period of the Stuarts, was rarely adopted down to the time of the Revolution, and never became common until after the Hanoverian family was seated on the throne. "In looking through so many volumes of county records," he says, "I have, of course, seen many thousands and tens of thousands of proper names, belonging to men of all ranks and degrees,--to noblemen, justices, jurymen, witnesses, sureties, innkeepers, hawkers, paupers, vagrants, criminals, and others,--and in no single instance, down to the end of the reign of Anne, have I noticed any person bearing more than one Christian name ...." [Walsh]
Middle school attested from 1838, originally "middle-class school, school for middle-class children;" the sense in reference to a school for grades between elementary and high school is from 1960. Middle management is 1957. Middle-of-the-road in the figurative sense is attested from 1894; edges of a dirt road can be washed out and thus less safe. Middle finger so called from c. 1000.
misprision (n.): "wrong action, a failure on the part of authority," early 15c., from Anglo-French mesprisioun "mistake, error, wrong action or speech," from Old French mesprision "mistake, wrongdoing, fault, blame, crime," from mespris, past participle of mesprendre "to mistake, act wrongly, trespass, transgress, break a law," from mes- "wrongly" (see mis- (2)) + prendre "take," from Latin prendere, contracted from prehendere "seize" (see prehensile).

In 16c., misprision of treason was used for lesser degrees of guilt (those not subject to capital punishment), especially for knowing of treasonable actions or plots but not informing the authorities. This led to the common supposition in legal writers that the word means "failure to denounce" a crime.
octave (n.): 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). Verse sense of "stanza of eight lines" is from 1580s; musical sense of "note eight diatonic degrees above (or below) a given note" is first recorded 1650s, from Latin octava (pars) "eighth part."

Three musketeers translates French les trois mousquetaires, title of the 1844 novel by Alexandre Dumas père.
tropic (n.): late 14c., "either of the two circles in the celestial sphere which describe the northernmost and southernmost points of the ecliptic," from Late Latin tropicus "of or pertaining to the solstice" (as a noun, "one of the tropics"), from Latin tropicus "pertaining to a turn," from Greek tropikos "of or pertaining to a turn or change; of or pertaining to the solstice" (as a noun, "the solstice," short for tropikos kyklos), from trope "a turning" (see trope).

Old English under hand meant "in subjection, in (one's) control or power."
wait (v.): c. 1200, "to watch with hostile intent, lie in wait for, plot against," from Anglo-French and Old North French waitier "to watch" (Old French gaitier "defend, watch out, be on one's guard; lie in wait for;" Modern French guetter), from Frankish *wahton or another Germanic source, from Proto-Germanic *waht- (cognates: Dutch wacht "a watching," Old High German wahten, German wachten "to watch, to guard;" Old High German wahhon "to watch, be awake," Old English wacian "to be awake;" see wake (v.)).

When speed, not stoutness, is the best of a horse, quite a contrary system is practised. With such a horse, the jockey plays a waiting game; that is, he carefully nurses him through the race, so as not to distress him by overpacing him; as the finish approaches, he creeps up to his horses by degrees, but does not quit them to go in front till he sees that the pace has made them "safe," -- when he lets loose and wins. [James Christie Whyte, "History of the British Turf," London, 1840]
wit (n.): "mental capacity," Old English wit, witt, more commonly gewit "understanding, intellect, sense; knowledge, consciousness, conscience," from Proto-Germanic *wit- (cognates: Old Saxon wit, Old Norse vit, Danish vid, Swedish vett, Old Frisian wit, Old High German wizzi "knowledge, understanding, intelligence, mind," German Witz "wit, witticism, joke," Gothic unwiti "ignorance"), from PIE *weid- "to see," metaphorically "to know" (see vision).

Witjar was old slang (18c.) for "head, skull." Witling (1690s) was "a pretender to wit."
nonagesimal: " Astronomy and Astrology . The point of the ecliptic which is highest above the horizon at any given time, being 90 degrees round the ecliptic from the point at which it intersects the horizon", Early 18th cent.; earliest use found in John Harris (c1666–1719), writer and lecturer on science.
