Hobnail

Hobnail (pronouned hob-neyl)

(1) A large-headed nail for protecting the soles of heavy boots and shoes, thus, when used as a modifier: hobnail boots.

(2) A small allover pattern consisting of small tufts, as on fabrics, or of small studs, as on glass.

(3) A rustic (obsolete).

(4) In medicine, a Slang term used by clinicians to describe the appearance of the organ in those suffering cirrhosis of the liver.

(5) In medicine, cellular morphology pathognomonic for clear cell adenocarcinoma of the ovary.

1585-1595: The construct is hob + nail.  Hob is related to hub, but the ultimate origin of both words is so obscure few etymologists have attempt to disentangle.  Nail in the sense of that which grows from the ends of digits is pre 900 from the Middle English nail & nayl, from the Old English negel (tapering metal) & nægl (fingernail (handnægl)).  It was cognate with the Old Frisian neil, the Old Saxon & Old High German nagal, the Dutch nagel & German Nagel and the Old Norse nagl (fingernail), all from the unattested Germanic naglaz; akin as derivative to the Lithuanian nãgas & nagà (hoof), the Old Prussian nage (foot) and the Old Church Slavonic noga (leg, foot). Nail in the sense used in "hobnail" is from the Middle English naylen, from the Old English næġlan, again, words with long, tortured histories.  The original sense was of the “short, thick nail with a large head", the construction using the element hob probably as an identification with the "rounded peg or pin used as a mark or target in games", that form of unknown origin and dating from the 1580s.  Because they were used to make heavy boots and shoes, the word was used figuratively from the seventeenth century for a "rustic person or simpleton", John Milton (1608–1674) in Colasterion (1645) writing “…the word Politician is not us'd to his maw, and therupon he plays the most notorious hobbihors, jesting and frisking in the luxury of his non-sense with such poor fetches to cog a laughter from us, that no antic hobnaile at a Morris, but is more hansomly facetious”.

From fireplace to fashion

Dating from 1505–1515, hub was a variant of obsolete hub hob (in a fireplace) and related to the obsolete hubbe from the 1510s and an etymology unrelated to the thirteenth century use as an affectionate diminutive for Robert or Robin.  Hob as a word to describe the side (the flat projection or iron shelf at the side of a fire grate, where things are put to be kept warm) of a fireplace was common by 1670s and in some English-speaking countries is used still to refer to the top cooking surface on a cooker or stove (the cooktop typically comprising several (often four) cooking elements also known as “rings” or elements”).  Etymologists are divided on whether the use of hob to describe a "clown, prankster" is a equating of such people with the yokels to whom it had long been applied or, a shortening for hobgoblin (the phrase “to play (the) hob" is documented in 1834 as meaning “to make mischief").  In quoits, a hob is a rounded peg used as a target.  In machine tools, it’s a kind of cutting tool, used to cut the teeth of a gear and can be used to refer to the hub or a wheel.  In zoology, a hub is a male ferret.

The long established meanings (1) the thin, horny plate at the ends of fingers and toes on humans and some other animals and (2) a spike-shaped metal fastener used for joining wood or similar materials ran in parallel.  It also one referred to a round pedestal on which merchants conducted business and a (now archaic) English unit of (usually cloth) measure length equivalent to 1 twentieth of an ell or one sixteenth of a yard (2 ¼ inches (57.15mm)).  The sense "fingernail" seems to have been the original.

The hobnailed boot (known as tackety boots in Scotland) has been used since antiquity, both by workmen and the military and for the same reasons: durability and traction.  In the army of Ancient Rome, they were called caligae and remained common in military formations until well into the twentieth century, supplanted only as techniques with rubber and synthetic materials improved.  Before the development of crampons, they were widely used in mountaineering.

Fracture

Fracture (pronounced frak-cher)

(1) The breaking of a bone, cartilage, or the like, or the resulting condition.

(2) The act of breaking; state of being broken.

(3) A division, break, breach, or split.

(4) The characteristic manner or appearance of breaking.

(5) In mineralogy, the characteristic appearance of the surface of a freshly broken mineral or rock; the way in which a mineral or rock naturally breaks

(6) To cause or to suffer a fracture in (a bone, etc).

(7) As Fraktur, a typeface of German origin.

Early 1400s: From the Middle English fracture (a breaking of a bone), from the fourteenth century Old French fracture, from the Latin fractūra (a breach, fracture, cleft), from fractus, past participle of frangere (to break), from the primitive Indo-European bhreg (to break) and a doublet of fraktur.  The sense of "a broken surface" dates from 1794.  As a transitive verb meaning “cause a fracture in”, use appears to have begun in the 1610s (implied in fractured) and the intransitive meaning "become fractured" is from 1830.  Fracture & fracturer are nouns, fractured & fracturing (used with an object) are verbs, fracturable, fractured & fractural are adjectives.

The Dürers Fraktur typeface.

The noun fraktur (German black-lettering) dates from 1886 from the German Fraktur (black-letter, Gothic type), also "a fracture, a break", again from the Latin fractūra and so- called because of the styles angular (ie “broken") letters.  Fraktur became a common style in German printing from circa 1540 and was later exported to the Pennsylvania German arts that incorporate the lettering.  Scholars consider Fraktur a fusion of the Textur and Schwabacher letter-forms, the characteristics of Textur evident in the Fraktyr minuscules.  Schwabacher, another black-letter form, was widely used in early German print typefaces and was still in use until the mid twentieth century by which time use was entirely supplanted by Fraktur, an extensive variety of these fonts carved.  The first Fraktur typeface was designed when Maximilian I (1459–1519; King of the Romans 1486-1519 & Holy Roman Emperor 1508-1519) commissioned a series of books and ordered a new typeface created specifically for this publication; this first iteration of Fraktur was designed by Hieronymus Andreae (circa 1490-1556), a craftsman noted also for his woodcuts.  

Fonts in transition: Nazi Party poster advertising a “Freedoms Rally” (the irony not apparent at the time), Schneidemuhl, Germany, (now Pila, Poland) in 1931 (left), Edict issued by Martin Bormann (1900–1945) banning the future use of Judenlettern (Jewish fonts) like Fraktur (the irony of the letterhead being in the now banned typeface presumably didn’t disturb the author) (centre) and (in modern Roman script), an announcement in occupied that 100 Polish hostages had been executed as a reprisal for death of two Germans in Warsaw, 1944 (right).

Sometimes, the message was the typeface itself; it imparted values that were separate from the specific meaning in the text.  The Nazi regime (1933-1945) in Germany was always conscious of spectacle and although in matters of such as architecture customs there was a surprising tolerance of regional difference, in some things it demanded uniformity and one of those was the appearance of official documents.  Early in his rule their rule, Adolf Hitler (1889-1945; Führer (leader), German head of government 1933-1945 & head of state 1934-1945) decreed that “German Black Letter” should be used for all official purposes (and it was used in the cover art of most early editions of Mein Kampf); Hitler, who to the end thought himself an “artist”, liked the heavy, angular form for its encapsulation of the Germanic.  Fraktur is probably the best known of these although it’s but one of a number of variations of the typeface and such was the extend of the state support for the font that the party was critical of newspapers, publishers & magazines which used more modern (and easier to read) forms (and they were used by the German military and civil service when legibility was important), a frequent criticism being the “Roman characters” somehow represented a “Jewish influence”.  In one of the ironies of history however, when it became apparent that when used in letters and notices distributed to enforce rule in the occupied territories the use of the font was counter-productive because it was so hard to read, the Nazis suddenly declared that Fraktur had become contaminated wand was thus proscribed as Judenlettern (Jewish letters), official documents thereafter rendered in modern Roman type.  Martin Bormann's edict was issued thus:

I announce the following, by order of the Führer:

It is false to regard the so-called Gothic typeface as a German typeface. In reality, the so-called Gothic typeface consists of Schwabacher-Jewish letters. Just as they later came to own the newspapers, the Jews living in Germany also owned the printing presses… and thus came about the common use in Germany of Schwabacher-Jewish letters.

Today the Führer… decided that Antiqua type is to be regarded as the standard typeface. Over time, all printed matter should be converted to this standard typeface. This will occur as soon as possible in regard to school textbooks, only the standard script will be taught in village and primary schools. The use of Schwabacher-Jewish letters by authorities will in future cease. Certificates of appointment for officials, street signs and the like will in future only be produced in standard lettering…

Broken bones, fractured bones

There’s a widespread perception among lay-people that when it comes to broken bones, there’s a difference between a fracture and a break, a fracture being a kind of crack which doesn’t result in a clear separation whereas in a break, there’s a visible gap between the two broken pieces.  However, to physicians, the two mean the same thing, the only difference being that “fracture” is the preferred medical jargon, whereas a “break” is just a term sometimes used casually with customers (whom they prefer to call patients).  Anatomists list fourteen distinguishing characteristics of fractures, adding that injuries may result in some overlap in the categorization and (at least) a duplication of terminology in any description.

(1) Avulsion fracture: A muscle or ligament pulls on the bone, fracturing it.

(2) Comminuted fracture: An impact shatters the bone into many pieces.

(3) Compression, or crush, fracture: This generally occurs in the spongy bone in the spine. For example, the front portion of a vertebra in the spine may collapse due to osteoporosis.

(4) Fracture dislocation: This occurs when a joint dislocates, and one of the bones of the joint fractures.

(5) Greenstick fracture: The bone partly fractures on one side but does not break completely, because the rest of the bone can bend.

(6) Hairline fracture: This is a thin, partial fracture of the bone.

(7) Impacted fracture: When a bone fractures, a piece of the bone may impact another bone.

(8) Intra-articular fracture: This occurs when a fracture extends into the surface of a joint.

(9) Longitudinal fracture: This is when the fracture extends along the length of the bone.

(10) Oblique fracture: An oblique fracture is one that occurs opposite to a bone’s long axis.

(11) Pathological fracture: This occurs when an underlying condition weakens the bone and causes a fracture.

(12) Spiral fracture: Here, at least one part of the bone twists during a break.

(13) Stress fracture: Repeated stress and strain can fracture a bone. This is common among athletes.

(14) Transverse fracture: This is a straight break across the bone.

Bones are (substantially) rigid organs that support and protect many organs as well as producing red and white blood cells and storing minerals.  While there are variations, a typical adult human has 206 separate bones which, although tough and sometimes slightly flexible to absorb stress, if the pressure sustained is beyond a certain point, the bone will fracture.  In casual use, this is called a “broken bone” but to physicians it’s always a fracture which means simply there’s a break in the continuity of the bone. Symptoms vary, including pain, bones protruding through the skin, swelling, distortion in the appearance of body parts (especially limbs & digits) and loss of function.  Generally, bone fractures are either traumatic or pathological.  A traumatic fracture is where blunt force trauma has been applied such as the impact injuries sustained by falling or hitting something hard.  Pathological fractures are those which are the result of diseases such as Osteoporosis, chronic kidney or liver conditions, rickettes and hypovitaminosis D.

Fractures are sub-classified by anatomical location (skull fracture, rib fracture etc (an in casual use broken arm, broken leg etc)).  Physicians further refine their descriptions by mapping on an orthopaedic schematic in which fractures are defined by their state such as open fracture (bone is visible and the skin ripped), closed fracture (skin is intact), compression fractures, incomplete fracture, linear fracture etc.  Bone fractures are now most often diagnosed through imaging, most commonly with X-rays and treatment consists of pain management, keeping bones intact with splints or screws (or surgery depending on severity).  In extreme cases, amputation may be required if an infection can’t be controlled.

Break was from the Middle English breken, from the Old English brecan (to divide solid matter violently into parts or fragments; to injure, violate (a promise, etc), destroy, curtail; to break into, rush into; to burst forth, spring out; to subdue or tame), from the Proto-West Germanic brekan, from the Proto-Germanic brekaną & brekanan (to break), from the primitive Indo-European bhreg- (to break) and a doublet of bray.  Etymologists list the brecan as a (class IV) strong verb; past tense bræc, past participle brocen), the Proto-Germanic brekanan source also of the Old Frisian breka, the Dutch breken, the Old High German brehhan, the German brechen and the Gothic brikan), all ultimately from the primitive Indo-European root bhreg- (to break).

It was related closely to the nouns breach, brake & brick. The old past tense brake is obsolete or archaic and while still sometimes erroneously used, it’s long been an irregular form.  The past participle is broken but the shortened form broke is attested from the fourteenth century and the Oxford English Dictionary reported it was "exceedingly common" in the seventeenth & eighteenth century.  The meaning in the Old English applied to bones but formerly had been used also of also of cloth, paper and other fabrics, the meaning "escape by breaking an enclosure" dating from the late fourteenth century whereas the intransitive sense "be or become separated into fragments or parts under action of some force" was known by the late twelfth and the sense of "lessen, impair" was noted in the late fifteenth.  

Forks in the meaning emerged continuously: "make a first and partial disclosure" is from early 1200s and "destroy continuity or completeness" in any way is from 1741.  As applied to physical legal tender (coins or bills), break was being used to describe “converting a larger unit into smaller units of currency" by 1882 although the oral tradition may have long predated this.  That favorite of authors and poets, the “break her heart” is an intransitive verb from the fourteenth century.  To break bread (share food with someone) is from the late 1300s while to break ground (to dig or plough) was noted first in 1674 while the now rare figurative sense "begin to execute a plan" is from 1709.  To break the ice in the sense of "overcome the feeling of restraint in a new acquaintanceship" is from circa 1600, the reference an allusion to the "coldness" found sometimes in encounters with strangers.  To break wind was first attested in the 1550s although it may have been long used as one of the many way of describing this ancient practice.  To break (something) out is though probably is an image from dock work, of freeing cargo before unloading it and it is documented from the 1890s.

While the ironic theatrical good luck formula “break a leg” appears not to have been documented until 1948, it’s thought to have been in use since at least the 1920s and has a parallels in the German Hals- und Beinbruch (break your neck and leg) and the similar Italian in bocca al lupo. (into the wolf's mouth), the standard response to which is crepi il lupo! (may the wolf die), truncate usually as simply crepi! (may it die) although, in a sign of the times, the animal welfare lobby has suggested viva il lupo! (may the wolf live) but this is said not to have caught on with the thespians.  According to one dictionary of etymology, the expression “break a leg” was in the seventeenth century used euphemistically, of a woman, "to have a bastard" although whether this had any relationship to the traditions of theatre isn’t noted.

The noun break (act of breaking, forcible disruption or separation) was derived from the verb circa 1300 and the break of day "first appearance of light in the morning" dates from the 1580s, that senses extended by 1725 to mean any "sudden, marked transition from one course, place, or state to another".  The sense of a "short interval between spells of work" applied originally between lessons at school and was from 1861, enduring to this day in concepts such as the notorious “spring breaks”.  The “lucky break” meaning "stroke of good luck" is attested by 1911, thought to be drawn from the game of billiards (where the break that scatters the ordered balls and starts the game is attested from 1865). The now archaic meaning "stroke of mercy" is from 1914 and the use in Jazz music to describe an "improvised passage, solo" is from 1920s.  Broadcasting adopted the term in 1941 and applied it variously to handle the intervals between programmes although it was later augmented by the “sting”, a short piece of music to cover any break.  The "mini-break" is a (UK) colloquial term for a short "holiday" of 2-3 days; it was popularized in Helen Fielding's (b 1958) 1996 novel Bridget Jones's Diary and is used sometimes as a euphemism for a dirty weekend.

Eurodollar

Eurodollar (pronounced yoor-oh-dol-er)

A US dollar deposited in or credited to an offshore (originally a European) bank.

1958: A compound word, Euro + dollar.  Euro is a contraction of Europe, from the Ancient Greek Εὐρώπη (Eurṓpē), now used often as Europa; the Eurodollar concept has no relationship to the latter-day (eurozone) currency.  Dollar is attested since circa 1500, from the early Dutch daler or daalder, from German Taler & Thaler, from the Sankt Joachimsthaler (literally “of Joachimstal”) the name for coins minted in German Sankt Joachimsthal (St. Joachim's Valley, now Jáchymov in the Czech Republic); the construct being Joachim + tal (valley) and cognate with the Danish daler.  Initially (in 1957) Eurodollars were known as “Eurbank dollars”, so named after the telex address of one of the first banks involved in the sanction-busting transactions (in the days of tightly regulated capital and forex (foreign exchange) markets, many thing were possible (even with notionally non-convertible currencies) but only a few had access to the mechanisms).  Eurodollar is a noun; the noun plural is Eurodollars (it's not uncommon for it to be used without the initial capital).

Eurodollars

Eurodollars are US dollars on deposit at banks outside the United States.  They’re thus a part of the US money supply not under the jurisdiction of the Federal Reserve (the Fed, the US central bank) and, because of the special role of the US dollar as the world’s reserve currency, are interesting in that they’re subject to oversight by a number of central banks which are national and not international institutions.  The term was originally coined for US dollars in European banks but soon came to refer to all offshore deposits.  Eurodollar is entirely a technical term of the money markets and has no connection with the latter-day currency of the Eurozone although, in the general population, there was some early confusion in the early days of the physical Euro, some mistakenly describing the new paper as Eurodollars.  Within the specialized world of the currency traders, the euro-prefix is sometimes used to refer to any currency held offshore so there’s also the Euroyen, the Europound and even the Euroeuro which, in a charming linguistic paradox, can exist anywhere except within the Eurozone.

In the years immediately following World War II (1939-1945), there was a worldwide shortage of US dollars, the quantity of which outside the US began significantly to increase only as Marshall Plan money began to recapitalize European economies and imports rose in the US, soon to become the largest consumer market of the post-war years.  Another important factor driving the deposits of US dollars into European banks were the pre-emptive moves by the major communist powers, the USSR and the PRC (communist China) to shift their assets from US banks to avoid Washington’s sanctions.  Peking acted in 1949 at the start of the Korean War (1950-1953); Moscow in 1956 after their "invasion" of Hungary.

Eurodollars grew in volume also as offshore banks began to offer higher yields on deposits than were available from US institutions; by the early 1970s some US$400 billion (when a billion dollars really was a lot of money) was booked offshore in both short and long-term deposits.  It’s now measured in multiples of trillions (at least for now, a trillion dollars is still a lot of money) but the most important development in the Eurodollar world came in 1981 with the introduction of Eurodollar futures contracts.  Eurodollar futures are an interest rate product, unlike currency futures where contracts are built around actual buying and selling of the commodity; they’re thus a derivative instrument where players bet on interest rate movements and are thus treated by traders as a form of gambling; back the right horse and one wins, back the wrong horse and one loses.  Beginning in 1981, during the early days of the neo-liberal de-regulation project, they were the first of the products which took advantage of the rules of casinos being applied to capital markets and none of the market crashes since 1987 would have been possible without derivatives.  That instability is inherent to the operation of a neo-liberal economy and not an unintended consequence; Ronald Reagan (1911-2004; US president 1981-1989) & Margaret Thatcher (1925–2013; UK prime-minister 1979-1990) understood that in a dynamic economy there would be winners and losers and viewed that as an indication of the healthy competition of free-market capitalism.  Their (publicly un-stated) argument was that the existence of a "social safety net" which would (at least temporarily) support the losers in a state just above starvation would be sufficient to guarantee social stability (ie stop the peasants revolting).    

Eurodollar futures traders who use the market to track short-term US interest rate expectations have for some time been pricing in a rate hike by the Fed by Q3 2022, quite an acceleration on what their earlier charts suggested but increasing uncertainty about the Fed’s reaction to US inflation numbers has seen some traders expect a tightening even earlier.  Some traders have had their Eurodollar fingers burnt before, watching the Fed maintain their existing position and sticking to their long-standing mantra that the US economy needs to achieve certain employment and inflation marks before interest rates will move but the view is now hardening that inflation numbers will force the issue.

The Fed’s position seems to belong to the pre-Omicron world which feels now such a distant memory.  The futures are a bet on the direction of the short-term London interbank offered rate (LIBOR), one of the most widely used interest rate benchmarks in global financial markets.  Investors hedge interest rate risk in the Eurodollar market and in early December 2020, the September 2023 Eurodollar futures contract showed an implied yield of 0.50%, suggesting traders were expecting the Fed to deliver a 25 basis-point hike by then.  Since then the world has changed so much that predictions for the inflation outcome seem enough for the Fed to reconsider the “Greenspan put” (named after Dr Alan Greenspan (b 1926; Chair of the US Federal Reserve 1987-2006) and the actions he took in ensuring sufficient liquidity remained in the US system for business to continue as close to "normal" as possible; now often called the "Fed put"), in place (off and on) for over thirty years, despite recent declines in US stocks and other risk assets, the tech-heavy Nasdaq having fallen over 10%.  That’s how much the specter of inflation can spook central bankers and the Eurodollar futures suggest the traders have priced-in a quarter-point rate rise for March and perhaps a full percentage point by the end of calendar year 2022.  Despite that, traders still are not writing an obituary for the Greenspan put, noting it has been debatably the most influential tool in the Fed’s century-long history and, as an essentially reactive institution, it’s revival to deal with even a few local difficulties will not be unexpected.

Umbra

Umbra (pronounced uhm-bruh)

(1) Shade; shadow, now restricted mostly to literary use.

(2) The invariable or characteristic accompaniment or companion of a person or thing.

(3) In astronomy, the complete or perfect shadow of an opaque body, as a planet, where the direct light from the source of illumination is completely cut off.

(4) In astronomy, the dark central portion of a sunspot.

(5) A phantom or shadowy apparition, as of someone or something not physically present; ghost; spectral image.

(6) An uninvited guest brought along by one who was invited (archaic).

(7) The fully shaded inner region of a shadow cast by an opaque object.

(8) One of the family Umbridae of mudminnows; a sciaenoid fish, the umbrine.

(9) In typography, a sans-serif display typeface released in 1935 as a variation of the earlier Tempo.  Similar to many contemporary art deco designs, it's constructed with a shadow effect, the letter shapes built as negative space and defined by a black dimensional shadow.

1590s: From the Latin umbra (literally “shade”; shadow), a doublet of umber and of uncertain origin.  If it was from the Old Latin omra, source may have been the primitive Indo-European hzmrup-, related to the Ancient Greek ἀμαυρός (amaurós) (dark) and “rot” & “rotten” in the Luwian hieroglyphic.  Etymologists also note the Hittite Maraššantiya (their name for the Kızılırmak River), and this Indo-European source is said to be a possible borrowing from a Semitic root ḥ-m-r (be red), linked to the Arabic ح م ر‎ (ḥ m r).  All agree there is a connection with the Lithuanian unksna.  The adjectives are umbral & umbrageous and the noun plurals are umbras & umbrae.

The early meaning was that of a “phantom or ghost," a figurative use drawn from the Latin umbra (shade, shadow), which gave rise to the later umbrage (A feeling of anger or annoyance caused by something offensive or (now rarely) a feeling of doubt, from the Middle French ombrage (umbrage), from the Old French ombrage, from the Latin umbrāticus (in the shade), from umbra (shadow, shade)).  The astronomical sense of a "shadow cast by the earth or moon during an eclipse" was first used during the 1670s.  The meaning "an uninvited guest accompanying an invited one" is from 1690s and was an invention in English, from a secondary sense used in Ancient Rome.

The related noun umber (brown earthy pigment) is from the 1560s, from the French ombre (in terre d'ombre), or the Italian ombra (in terra di ombra), both from the Latin umbra (shade, shadow) or otherwise from Umbra, the feminine form of Umber "of or belonging to Umbria, the region in central Italy from where the coloring material was first discovered.  Burnt umber, specially prepared and redder in color, is attested from circa 1650 and distinguished from raw umber, both well-known to artists of the era.

It’s the cosmic coincidence of the relationship between the diameter of the Moon and its distance from the Sun which makes solar eclipses such a spectacular sight from planet earth.  On other planets, where the relationship is different, solar eclipses may not be as enchanting.  A solar eclipse happens sometimes as the Moon moves between the Sun and Earth, the Moon blocking the light of the Sun from reaching Earth.  Astronomers classify solar eclipses into three types:

(1) A total solar eclipse which is visible from a small area on Earth.  Those who see a total eclipse are those standing in the center of the Moon's shadow when it hits Earth. The sky becomes very dark, as if it were night. A total eclipse occurs only when the Sun, Moon and Earth are in a direct line.

(2) A partial solar eclipse happens when the Sun, Moon and Earth are not exactly aligned, the sun appearing to have a dark shadow on a small part of its surface.

(3) In an annular solar eclipse, the Moon seems further because the annular happens when the Moon is farthest from Earth and thus does not block the entire view of the Sun, instead looking like a dark disk on top of a larger Sun-colored disk.

A solar total eclipse.

Solar eclipses are not rare, visible around every eighteen months somewhere on Earth although the viewing spot is always relatively small.  Unlike lunar eclipses, solar eclipses last only a few minutes.  The umbra is the darkest part of a shadow, especially the cone-shaped region of full shadow cast by Earth, the Moon, or another body during an eclipse. In a full lunar eclipse, which generally lasts for one or two hours, the entire disk of the Moon is darkened as it passes through the umbra. During this period the Moon takes on a faint reddish glow due to illumination by a small amount of sunlight that is refracted through the Earth's atmosphere and bent toward the darkened Moon; the reddish tint is caused by the filtering out of blue wavelengths as the sunlight passes through the Earth's atmosphere, leaving only the longer wavelengths on the red end of the spectrum.

The umbra is the innermost and darkest part of a shadow, the area in which the light source is entirely obscured by the occluding body and if standing in this space, the viewer will experience a total eclipse.  Viewed in the abstract, the Sun, Moon & Earth all being (almost) spherical, umbra forms a right circular cone and, if viewed from the cone's apex, the two bodies will seem the same size.  The penumbra, from the Latin paene (almost, nearly) is the region in which only some of the light source is obscured by the occluding body so the viewer standing in the experiences a partial eclipse.  The antumbra, from the Latin ante (before) is the region from which the occluding body appears entirely within the disc of the light source.  The viewer standing in this apace experiences an annular eclipse, which manifests as a bright ring visible around the eclipsing body.  If the viewer is able to move closer to the light source, the apparent size of the occluding body increases until it causes a full umbra.

An umbraphile (shadow lover) is a person with much interest in eclipses, often making extraordinary efforts to travel to see them.  The construct is umbra +‎ phile.  Phile is from the Latin -phila, from the Ancient Greek φίλος (phílos) (dear, beloved) and from the same source is -phil, a word-forming element meaning "one that loves, likes, or is attracted to," via the French -phile and the Medieval Latin -philus in this sense, from the Ancient Greek -philos, a common suffix in personal names (such as Theophilos), from philos (loving, friendly, dear; related, own) and related to philein (to love) which is of unknown origin.  One authoritative etymologist suggests the original meaning was "own; accompanying" rather than "beloved."

Umbraphilia emerged as a niche in nineteenth century high-end tourism, gentlemen scientists and society figures sailing around the world to observe and sometimes report their findings.  The longest known observation of a solar eclipse was that undertaken on 30 June 1973 when a group travelled on board the Concorde, enjoying seventy-four minutes of totality.

Leftover

Leftover (pronounced left-oh-ver)

(1) Usually as leftovers; food remaining uneaten at the end of a meal, especially when saved for later use.

(2) Anything left or remaining from a larger amount; remainder.

(3) A casual (and disparaging) term used in the People's Republic of China to describe women still un-married after the age of twenty-six. 

1878: A compound word left + over; the construct being a noun use of verb phrase left over.  The meaning is always in the sense of left (“remaining, abandoned”) + over (“excess”).  Left is from the Middle English left, luft, leoft, lift & lyft, from the Old English left & lyft (air, atmosphere) from the Proto-Germanic luft with which may be compared the compared the Scots left (left), the North Frisian lefts, left & leefts (left), the West Frisian lofts (left), the dialectal Dutch loof (weak, worthless), and the Low German lucht (left).  Over is from the Middle English over from the Old English ofer from the Proto-Germanic uber (over), from the primitive Indo-European upér, a comparative form of upo; akin to the Dutch over, the German ober & über, the Danish over, the Norwegian over, the Swedish över, the Icelandic yfir, the Faroese yvir, the Gothic ufar, the Latin super, the Ancient Greek ὑπέρ (hupér), the Albanian upri (group of peasants) and the Sanskrit उपरि (upári).  The hyphenated left-over (remaining, not used up) is from 1890 as a noun meaning "something left over" is from 1891.  The sense of (the almost always plural) leftovers “excess food after a meal" (especially if re-served later) dates from 1878.  In this sense, Old English had metelaf.

Leftover women

Sheng nu (剩女; shèngnǚ), most often translated as "leftover women" is a phrase (usually considered derogatory), which describes Chinese women who remain unmarried by their late twenties.  First promulgated by the All-China Women's Federation (ACWF) as a promotion of government programmes, it’s been used in other countries but remains most associated with People's Republic of China (PRC).  As a demographic phenomenon, it was once unexpected because the conjunction of the PRC's one-child policy and the disproportionate abortion of female foetuses had led to a distortion in the historic gender balance.  Births in China since the one-child policy was introduced in 1979 have averaged 120 males for every 100 females compared to a global ratio of 103:107.

The term appears to have entered common-use in 2005-2006 and seems first to have appeared in the Chinese edition of Cosmopolitan.  Unlike most of Cosmopolitan’s editorial content, the Chinese Communist Party (CCP) took it seriously and instructed the ACWF (a kind of cross between the CWA (Country Women’s Association) and the PLA (People’s Liberation Army) to publish articles stigmatizing women still unwed by their late twenties.  Borrowing from Maoist tradition (if not theory), the ACWF provided a useful analysis of the problem, concluding that while “pretty girls” didn’t need much education to find a rich partner, “average or ugly” ones who seek higher degrees thinking it will “increase their competitiveness” in the marriage market are delusional; all that happens is they become old “…like yellowed pearls."  The rhetorical flourishes aside, they had a point.  As the numbers of highly educated women rose, the numbers of potential husbands they found acceptable did not.  What the distorted gender balance created by the one-child policy and the selective-sex abortion preferences had produced was an increasingly educated and middle-class female minority not impressed by a less schooled and more rural male majority.

“Leftover women” seemed the choice in print but on the internet, the punchier 3S or 3SW (Single, Seventies (referring to the then prominent 1970s birth cohort) and Stuck) was also used instead of sheng nu.  There is an equivalent term for men, guang gun (bare branches (ie men who do not marry and thus do not add branches to the family tree)); shengnan (leftover men) does exist but is rare.

CCP demographers had expressed concerns about the social and economic implications of the one-child policy as early as the 1990s.  In the new century, the policy was first selectively relaxed, then revised to permit additional children for those selected by the CCP as desirable breeders and, on 31 May 2021, at a meeting of the of the CCP Politburo, the three-child policy (三孩政策) was announced.  The session, chaired by Xi Jinping (b 1953; CCP general secretary 2012- & PRC president 2013-), followed the release of the findings of the seventh national population census which showed the number of births in mainland China in 2020, at twelve million, would be the lowest since 1960, an indication of the demographic trend causing the ageing of the population.  The Xinhua state news agency then announced the three child policy would be accompanied by supportive measures to “maintain China's advantage in human resources” but surveys suggested the section of the population the CCP would like to see produce three children per household were generally unwilling to have even two, the reason overwhelmingly the high cost of living in Chinese cities.  The announcement on 26 July 2021 permitting Chinese couples to have any number of children was thus greeted by most with restrained enthusiasm.

The problem of re-production is not restricted to the PRC, the birth rate in South Korea now down to around .8 per woman while a rate around 2.1 is necessary if the population is to be sustained.  What exacerbates the problem in the PRC is the simple lack of women of child-bearing age, caused by the distorted male/female live-birth rates in the decades following the imposition of the one-child policy and any vague hope the long stretches of lock-downs may have encouraged procreation were not realized.  Despite that disappointment, the CCP wasn't discouraged and embarked on a new propaganda campaign making it clear to young women that having babies was part of their patriotic duty to the motherland: pregnancy was now compulsory.  In the West, the decline in the birth rate has for some time been thought a problem, largely because of the impending acceleration in the distortion between those of working age (paying into the system) and those not generating income (extracting from the system).  Of late however, influenced by the un-anticipated rapidity in the advances in artificial intelligence (AI) and robotics, theorists are re-visiting the models and pondering the implications.
