HODLing

Hodling (pronounced hodd-ling or hold-ing)

The continuing to hold one’s position in a market regardless of movements in that market.  Rationale is that value of that which one is holding will again rise again and selling will result only in actual or nominal (opportunity cost) losses.

2013: Word created on 18 December 2013 when a contributor to a Bitcoin forum, bitcointalk.org, apparently after enjoying most of a bottle of whisky, misspelled hold, a transposition probably not uncommon after too much drink given where the “o” and “l” keys sit on the qwerty keyboard.  Meme-makers soon decided hodl a backronym for hold on for dear life, a sentiment probably familiar to many who once held Bear Stearns or Lehman Brothers paper.  Most frequently used related form is hoddle and use appears restricted to the cryptocurrency community; preferred spelling is HODler.  Which of the pronunciations hodd-ling or hold-ing will emerge as a standard is unclear, as is whether hodl will even survive as a word.

Dictionaries cite dozens of definitions for hold so hodl is potentially a handy addition to English because its meaning is so specific, either in the context of cryptocurrencies or markets generally.  Whether use moves beyond its niche or even survives won’t for some time be clear.  The markets have managed with hold for some centuries and it may be that the trade in cryptocurrencies, however it evolves, may find hold adequate.  HODler manifestos have been published:

Rule 1: A True HODLer Does Not Sell Their Coin

HODler The first and most important rule of the HODLer Manifesto is to never sell your coin. A HODLer may spend their coin (see rule 5), but a HODLer does not sell. Only the weak sell, and they soon regret doing so.

Rule 2: A True HODLer Buys the Dip

If the fiat price of their coin drops, a HODLer will buy more, provided they have the means to do so. Under no circumstances would a HODLer panic sell because they see the price going down. The only case where a HODLer is not regularly buying the dips is when all their fiat is already invested.

Rule 3: A True HODLer Remains Steadfast In Spite of FUD

Whether there’s news that China is banning your coin again, or your favourite exchanged got hacked, you as a HODLer will continue to HODL. A HODLer stays the course regardless of who is sowing seeds of fear, uncertainty, and doubt. Disregard the news. Remember that the naysayers are usually those who have a lot to lose from your coin’s success, or those who resent HODLers for going to the moon.

Rule 4: A True HODLer Keeps Their Coins Off Exchanges and Online Wallets

Wallet No exchange or online wallet is immune from rogue employees, security mistakes, or simple negligence. A HODLer will keep their coins secure by using a paper or hardware wallet, instead of relying on any third parties for custody or safe keeping. A HODLer always controls their own private keys.

Rule 5: A True HODLer Buys Goods and Services With Their Coin

Should you decide to spend your coins, find vendors who accept your coins directly rather than selling or using fiat-based bridges (such as prepaid Visa cards). By spending your coins, you fuel the ecosystem of fellow HODLers. Do not become a spendthrift either, or you will soon find yourself without coin.

Rule 6: A True HODLer Spreads the Good Word

Sharing is Caring Do tell your friends and family about the goodness of your coin, but do not be pushy, or pressure others into buying your coin. They may not share the same values as you. Try to educate them without being patronizing, and stick to the facts rather than appealing to emotions (like FOMO). Refer them to good resources, and let them make up their own mind.

Rule 7: A True HODLer Does Not Get FOMO When Another Coin Rises

When you see other coins quickly rising in market cap rankings, you will not be distracted. They too will fall back from whence they came. Resist the temptation to dump your coin and pump another. This is usually a futile exercise, and is a quick way to make a big fortune into a small fortune. If you do, in spite of better sense, decide to purchase a new coin, weight your holdings by market cap to manage your risk.

Rule 8: A True HODLer Will Run Their Own Full Node

To ensure their coin remains healthy, and to participate in consensus, a HODLer runs their own full node if possible. There is truth in numbers, and a HODLer will always remain true to their coin. By participating in consensus a HODLer is in complete control of their own destiny, free from tyranny, censorship, and oppression.

Hotline

Hotline (pronounced hot-lahyn)

(1) In Canadian use, talkback radio; of or relating to a radio program that receives telephone calls from listeners while on-air.

(2) A direct telecommunications link, either as a telephone line, teletype circuit or other connection, enabling immediate communication between heads of state and intended for use in times of crisis.

(3) A telephone service enabling people confidentially to speak with someone about a personal problem or crisis.

(4) A telephone line providing customers or clients with direct access to a company or professional service.

1950-1955: Hot was from the Middle English hot & hat, from the Old English hāt (hot, fervent, fervid, fierce), from the Proto-Germanic haitaz (hot), from the primitive Indo-European kay- (hot; to heat).  It was cognate with the Scots hate & hait (hot), the North Frisian hiet (hot), the Saterland Frisian heet (hot), the West Frisian hjit (hot), the Dutch heet (hot), the Low German het (hot), the German & Low German heet (hot), the German heiß (hot), the Danish hed (hot), the Swedish het (hot) and the Icelandic heitur (hot).  Line was from the Middle English line & lyne, from the Old English līne (line, cable, rope, hawser, series, row, rule, direction), from the Proto-West Germanic līnā, from the Proto-Germanic līnǭ (line, rope, flaxen cord, thread), from the Proto-Germanic līną (flax, linen), from the primitive Indo-European līno- (flax).  The Middle English forms evolved under the influence of the Middle French ligne (line), from the Latin linea and the oldest sense of the word is "rope, cord, thread"; from this the senses "path" and "continuous mark" were derived.  That was also the source of the use in telecommunications, telephone traffic originally routed along physical lines, usually a pair of copper wires; the use of “cable” “telegraph” & “wire” to describe the messages sent across these means of transmission had a similar gestation.  The spelling variously is hotline, hot-line and hot line and inconsistencies in use are common.

The Moscow–Washington hotline

President Warren Harding with the first telephone installed in the Oval Office, 29 March 1929.

The Moscow–Washington hotline (technically the Washington–Moscow Direct Communications Link) was established in 1963 after the experience of the Cuban Missile Crisis suggested to US diplomats that had the channels of communication been able more quickly to deliver messages, it may have been possible to resolve matters before they reached to point of crisis.  The solution was felt to be a means of immediate, secure communication between the Kremlin and the White House so the leaders of the USSR and USA instantly could communicate in times of crisis, the imagery being two telephones connected by a long line between Moscow and Washington DC.  Unfortunately, although the classic image is of red analogue telephones (without a dialing mechanism) sitting on the two desks, telephones actually weren’t part of the system.  There has been a telephone on the president’s desk in the White House since 1929 but never a red one and although there have been many red-colored phones in both civilian and military service in the US, there was never one connected to the Moscow–Washington hotline.

The photograph of George W Bush was a fake although it circulated widely, complete with a doctored photo-frame in the background, containing a picture of then UK prime-minister Tony Blair. 

The classic hotline was between two callers but there's no reason why they can't be multi-node: Four-way call, Mean Girls (2004).

The reasons telephones weren’t thought suitable was that in moments of crisis in international relations, it’s vital there be no misunderstandings and a conversation between two people speaking different languages through translators, separated by thousands of miles over a phone line of sometimes variable quality, would be inherently error-prone.  Additionally, a certainty of historic record in important in diplomatic discourse so a device which committed everything to paper, in text, was required.  What was adopted was the technology which was at the time the most appropriate, something robust, reliable and suitable for technicians at both ends; in 1963, that was the teleprinter (also known as teletypewriter, teletype or TTY), an electromechanical device which had for decades been used in inter-continental communications, much of its popularity due to the ability to bolt it to a variety of communications channels.  Over the years, the technology has changed to take advantage of advances including an era (which began during the Reagan administration (1981-1989)) in which the hotline was facsimile (fax) based, something which sounds now archaic but which was at the time both fast and secure.  Satellite links have for years been used and there is now a secure fibre-optic link.   

Hotline Teleprinter, the Pentagon, circa 1966.

Before the term hotline came into use in the 1950s, there had actually been a “hotline” which really did use telephones: In 1943, the first use of a scrambler (an early, analogue form of voice-encryption) was the system installed between the White House Downing Street to render secure conversations between President Roosevelt and Prime-Minister Churchill and both the UK military and civil service had for years used hotlines (literally dedicated phone-lines) between departments.  The idea has spread and other countries have either installed hotlines or at least flirted with the idea although, the implementation has been patchy; some installed and never commissioned or switched off during periods of heightened tensions.  The usual suspects have been involved, China–USSR (and later Russia), China-India, China–United States, China-Japan, North Korea-South Korea and India–Pakistan.

A fake Hotline.

One linguistic quirk in the name of the Moscow–Washington hotline is misleading in that while the Russian end does terminate in Moscow, the US end is technically not in Washington DC but under military control in a secure facility in the Pentagon, located in Langley, Virginia where, twenty-four hours a day, a technician and translator attend the office.  Despite reality, in many fictional depictions of US-Soviet relations in the Cold War and beyond, literal, bright-red analogue telephones sometimes appeared, long after any such devices had been replaced, an example of the way in which verisimilitude in fiction is constructed sometimes by conforming to a popular perception of reality rather than reality itself.

Four-node hotline, Mean Girls (2004).

Corps

Corps (pronounced kore)

(1) A military body with a specific function (intelligence corps, medical corps etc).

(2) A military unit of ground combat forces consisting of two or more divisions and other troops.

(3) A group of persons associated or acting together (diplomatic corps; press corps et al).

(4) In printing, a continental designation that, preceded by a number, indicates size of type in Didot points of 0.0148 inches (3.8 mm).

(5) An alternative word for a corpse (obsolete).

(6) In classical ballet, as the corps de ballet, the group of dancers who are not soloists

1225-1275; Middle English corps and Middle French cors, both derived from Latin corpus (body) from the primitive Indo-European kwerp- (body, form, appearance).  Sense in English evolved from dead body (thirteenth century) to live body (fourteenth century) to body of citizens (fifteenth century).  The modern military sense (dating from 1704) is from French corps d'armée, picked up in English during Marlborough's campaigns, the use at the time not based on a specific number of troops but the more generalized "a part of an army expressly organized and having a head".  In English, pronunciation was corse at first and this persisted until the eighteenth century by which time it was archaic except for poetic use.

The field corps, a tactical unit of an army and which contained two or more divisions, was one of Napoleon’s structural innovations in military re-organization although such formations, ad-hoc or planned, had long been a known feature of battlefield tactics. The word was soon extended to other organized groups under a leader, as in corps de ballet (1826) or corps diplomatique (1796), although with the latter, the leader (dean of the diplomatic corps) is an appointment for ceremonial purposes, often, by convention, extended to the papal nuncio.  The special use Corpsman (enlisted medical auxiliary) was used first by the US military in 1941.

The corps in army organizational structures.

Standard of the Corps of Royal Engineers.  Specialized formations (intelligence corps, medical corps et al) exist in all branches of the military with no rules or consistency in the numbers of their establishment.  However, whereas the structures of navies (squadrons, flotillas, fleets etc) and air forces (flights, squadrons, wings, groups etc) are based on the number of vessels or airframes attached, the army (mostly) defines its organization by the number of personnel allocated, the numbers listed below generally indicative based on historic formations.  

Command Group   Size of Command

Army Group           400,000-2,000000

Army                     150,000-360,000

Corps                    45,000-90,000

Division                 10,000-30,000

Brigade                 1500-5000

Regiment              1500-3500

Battalion               500-1500

Company              175-250

Platoon                 12-60

Squad                   4-24

Most armies use all or a subset of the above although the numbers vary (greatly).  A division is made up of 3-4 brigades, a corps of 3-4 divisions and so on.  In western armies, the numbers listed above reflect the big-scale mass formations used during World War II; peacetime armies are a fraction of the size but the organizational framework is retained, most forces actively using only the smaller clusters.  During WWII, US army command groups tended to be up to twice the size of British units though within the same army, divisions often varied in size, an infantry division being usually larger than the armored.  A corps can be assembled from the armies of more than one nation, the Australian & New Zealand Army Corps (ANZAC) being formed in 1915 prior to deployment as part of the Dardanelles Campaign.  Other organizational tags such as squadron also exist but tend now either to be rare or, like battery, applied to specialized units based on function rather than size.  A special case is troop which is generally an alternative word for platoon but there are exceptions.

In twenty-first century wars, entire divisions are rarely committed operationally and brigade level engagements are regarded as large-scale.  In the world wars of the twentieth century, uniquely big, multi-theatre affairs, the standard battlefield unit tended to be the division of which the Soviet Union fielded nearly five-hundred.  The numbers in the world wars were certainly impressive but in a sense could be deceptive, the percentage of those listed on the establishment actually committed to combat sometimes surprisingly low (though this tended to apply less to those of the USSR).  One British prime-minister, pondering this, complained to the Chief of the Imperial General Staff (and the CIGS was a noted ornithologist) that the army reminded him “…of a peacock; all tail and very little bird”.  Dryly, the field marshal responded by pointing out “the peacock would be a very poorly balanced bird without its tail”.

Royal Flying Corps publicity photograph, 1917.

The Royal Flying Corps (RFC) was created in 1912 as the air arm of the British Army.  Late in the First World War, it was merged with Royal Naval Air Service (RNAS), the Royal Air Force (RAF) being formed on 1 April 1918.  Military aviation didn't however become exclusive to the RAF, the army retaining its own operations, mainly for communications, reconnaissance and meteorological services.  The Admiralty was never entirely happy about the merger and the Fleet Air Arm (FAA), though still an operational unit of the RAF, was formed in 1924, necessitated by the launching that year of the of the Royal Navy's first aircraft carrier.  By 1937, even the RAF was convinced naval aviation was different and in 1939 FAA reverted to the Admiralty, operating both from carriers and ground stations.

United States Army Air Corps Curtiss P-40, 1940.

Military aviation in the US was formalized in 1907 with the creation of the United States Army Air Corps (USAAC); the service renamed to United States Army Air Force (USAAF) in 1941.  It wasn't until 1947 when, as part of the National Security Act of that year that the US Air Force (USAF) was established as the fourth branch of the US military.  Remarkably, given it was the US which in the 1940s created the parameters for modern, carrier-based warfare, the admirals, still hankering for the great set-piece, high seas clash of the battleship fleets (which would never happen, largely because of aircraft), tried in 1919 to abolish naval aviation because there was “…no use the fleet will ever have for aviation."  The naval aviators (pilots work for the air force they say) however weren't forced to walk the plank and the navy received its first carrier in 1922 though the intra and inter service squabbles would continue for years.

Invasion

Invasion (pronounced in-vey-zhuhn)

(1) A military action consisting of armed forces of one (usually geopolitical) entity entering territory controlled by another such entity, generally with the objective of conquering territory & altering or overthrowing an established government.

(2) The entrance or advent of anything troublesome or harmful, as disease; the entry without consent of an individual, group or species into an area where they are not wanted.

(3) Entrance as if to take possession or overrun.

(4) Infringement by intrusion.

(5) In pathology, the spread of cancer from its point of origin into surrounding tissues.

(6) In Botany, the movement of plants to a new area or to an area to which they are not native.

(7) In surgery, the breaching of the skin barrier.

1400–1450: From the late Middle English, From the Middle French invasion from the Late Latin invāsiōnem, accusative of invāsiō, from invāsus, past participle of invādō, the construct being in- (in, into) +‎ vādō (I go, rush).  Invāsus was the past participle of invādere + -iōn-.  The noun was from the mid-fifteenth century Middle English invasioun (an assault, attack, act of entering a country or territory as an enemy), from the twelfth century Old French invasion (invasion, attack, assault), from the Late Latin invasionem (nominative invasio) (an attack, invasion), the noun of action from the past-participle stem of invadere (to go, come, or get into; enter violently, penetrate into as an enemy, assail, assault, make an attack on), the construct being in- (in) from the primitive Indo-European root en- (in)) + vadere (to go, to walk, go hastily) from the primitive Indo-European root wadh- (to go) (source also of the Old English wadan (to go) and the Latin vadum (ford).  Of the meanings in the extended senses, of diseases it referred to "a harmful incursion of any kind; with reference to rights etc, it was about "infringement by intrusion, encroachment by entering into or taking away what belongs to another".

The later noun incursion (hostile attack) dates from the early fifteenth century, from the fourteenth century Old French incursion (invasion, attack, assault) or directly from the Latin incursionem (nominative incursio) (a running against, hostile attack), the noun of action from past participle stem of incurrere (run into or against, rush at).  Although in practice often synonymous with invasion, “incursion” is often in a specifically military context used to distinguish a operation which is either a prelude to or a distinct part of an invasion.  It’s a practice of historians rather than a convention of use and is one of a number of words used to describe the mechanics of an invasion including: aggression, assault, breach, infiltration, infringement, intrusion, offensive, onslaught, raid, violation, entrenchment, foray, infraction, inroad, irruption, maraud, offense & transgression.

The (second) Italian invasion of Ethiopia

Italy’s invasion in of Abyssinia (Ethiopia) in 1935 was a curious business.  Conceived by the Duce (Benito Mussolini (1883-1945, prime-minister of Italy 1922-1943) as the means by which his country might acquire a colony of note, a rightful thing he thought denied by the ineptness of previous regimes in Rome and the unfairness of the treaty of Versailles from which Italy had gained so little from the spoils of victory to which she’d made a slight contribution.  In his mind too was the memory of the last Italian adventure in East Africa when in 1896 the Ethiopians had inflicted upon the would-be conquerors from Europe a brutal defeat on the battlefield at Adowa, seared in the memory of the Italian army as the headline “Ten-thousand dead and seventy-two cannon lost”.  Looking first at the map of the old Roman Empire, then the splendid possessions held by Britain and France and finally the few sparse deserts which made up “his” empire, the Duce decided on an African conquest.  Even in 1935 it was seen in other European capitals as an unfashionable venture, the idea of the conquest of other people’s lands no longer the respectable thing to do and there was an increasing awareness that nor was it any longer the profitable thing to do.  Mussolini however was convinced and embarked on what proved to be imperialism’s last great set-piece crusade.

David Low (1981-1963), 1936.

The world of 1935 however was a different place than that of the nineteenth century.  Not only was Ethiopia internationally recognized (including by Italy) as a sovereign, independent state but it was also a member of the League of Nations (1920-1946), the predecessor of the United Nations (UN), formed in an attempt to ensure there could never be another world war, the mechanisms of resolving conflict listed in its covenant. Central to the covenant was collective security and the settling of international disputes through negotiation and arbitration.  The League’s approach did not much commend itself the Mussolini who announced Ethiopia presented a military threat to the neighboring Italian possessions of Eritrea and Italian Somaliland and that anyway his historic destiny was to fulfil a civilizing mission which would “…help Africa to progress from its primitive state.”

David Low, 1936

Obviously the League of Nations could not countenance one of its members invading another and the Britain’s foreign secretary, Sir Samuel Hoare (later Viscount Templewood, 1880–1959; UK Foreign Secretary 1935), making what may have been the finest speech the unfortunate assemble ever heard, declared the UK was wholly committed to the principle of collective security and that acts of unprovoked aggression strenuously would be resisted.  Hoare’s principled stand lasted as long as the next cabinet meeting in London and as quickly it became clear that member nations of the League would not be imposing any economic or diplomatic sanctions which had any substantive effect, let alone threaten a military response, Mussolini invaded.  Able to deploy aircraft, chemical weapons, heavy artillery, tanks and other armored vehicles, the Italians slowly secured victory, culminating in the battle of Amba Aradam, the biggest and bloodiest battle of the imperial era.

David Low, 1936.

By then Hoare had been forced from office by the public outcry over his back-channel deal with the palindromic Pierre Laval (1883–1945, French prime minister 1935-1936 and later executed for his role in the Vichy administration (1940-1944)) which, although in the tradition of the League’s earlier acts of conciliation in the far east, is better remembered as a preview of the later techniques of appeasement which so failed to satisfy Hitler.  What Hoare and Laval had agreed was a deal under which two-thirds of Ethiopia would be ceded to Italy in exchange for the Ethiopians being granted a land-corridor to a nearby port.  Both the belligerents actually anyway rejected the deal and Hoare was the sacrificial scapegoat for a plan which had the cabinet’s support.

The affair revealed the European democracies as divided and the League of Nations as ineffectual and doomed.  Although the League would continue to talk, few now listened as Europe drifted to war and after hostilities began, the organization went into abeyance except for a skeleton administrative structure which ticked-over until the League was dissolved in 1946.  Of the many speeches made after the Italian invasion, the only one still remembered is that made in June 1936 the Emperor Haile Selassie I (1892–1975; Emperor of Ethiopia 1930-1974) in which he condemned the league for its inaction, prophesized war and warned the assembled delegates “It is us today.  It will be you tomorrow.”

Conglomerate & Agglomerate

Conglomerate (pronounced kuhn-glom-er-it or kuhng-glom-er-it (noun & adjective) and kuhn-glom-uh-reyt or kuhng-glom-uh-reyt (verb))

(1) Anything composed of heterogeneous materials or elements; mass.

(2) A corporation consisting of a number of subsidiary companies or divisions in a variety of unrelated industries, usually as a result of merger or acquisition.

(3) A coarse-grained sedimentary rock consisting of round rock fragments cemented together by hardened silt, clay, calcium carbonate, or a similar material. The fragments (clasts) have a diameter of at least 2 mm (0.08 inches), vary in composition and origin, and may include pebbles, cobbles, boulders, or fossilized seashells. Conglomerates often form through the transportation and deposition of sediments by streams, alluvial fans, and glaciers.

(4) Gathered into a rounded mass; consisting of parts so gathered; clustered.

(5) Consisting of heterogeneous parts or elements.

(6) Of or relating to a corporate conglomerate.

(7) In geology, of the nature of a conglomerate.

(8) To bring together into a cohering mass.

(9) To gather into a ball or rounded mass.

1565–1575: From the Latin conglomerātus, past participle of conglomerāre (to roll-up), from glomerāre (to wind into a ball), the construct being con- + glomer- (stem of glomus) (ball of yarn or thread) + -ātus (-ate).  The prefix con- was from the Middle English con-, from the Latin con-, from the preposition cum (with), from the Old Latin com, from the Proto-Italic kom, from the primitive Indo- European ḱóm (next to, at, with, along).  It was cognate with the Proto-Germanic ga- (co-), the Proto-Slavic sъ(n) (with) and the Proto-Germanic hansō.  It was used with certain words to add a notion similar to those conveyed by with, together, or jointly or with certain words to intensify their meaning and, later, to indicate being made from or bringing together of several objects.  The suffix -ate was a word-forming element used in forming nouns from Latin words ending in -ātus, -āta, & -ātum (such as estate, primate & senate).  Those that came to English via French often began with -at, but an -e was added in the fifteenth century or later to indicate the long vowel.  It can also mark adjectives formed from Latin perfect passive participle suffixes of first conjugation verbs -ātus, -āta, & -ātum (such as desolate, moderate & separate).  Again, often they were adopted in Middle English with an –at suffix, the -e appended after circa 1400; a doublet of –ee.  Related forms include conglomeratic, conglomeritic, conglomerated, conglomerating, conglomerateur, conglomeration & conglomeratize.

Agglomerate (pronounced uh-glom-uh-reyt (adjective & noun) and uh-glom-er-it (noun))

(1) To collect or gather into a cluster or mass.

(2) Gathered together into a cluster or mass.

(3) In botany, crowded into a dense cluster, but not cohering.

(4) In geology, a mass of angular volcanic fragments united by heat; distinguished from conglomerate.

(5) In meteorology, an ice-cover of floe formed by the freezing together of various forms of ice.

1675-1685: From the Latin agglomerātus, past participle of agglomerāre, the construct being ad- (to) + -glomerāre (to wind or add into a ball), from glomus (a ball; a mass), from globus (genitive glomeris), (a ball of yarn) of uncertain origin.  Related forms are the adjective agglomerative, the nouns agglomerator & agglomeration and the verbs (used with or without object), agglomerated & agglomerating.  The intransitive sense "grow into a mass" dates from 1730.

Conglomerate rocks are those compose of mostly rounded, gravel-size clasts, a matrix of finer grained sediments, such as sand, silt or compressed clay filling the gaps between the clasts, the form held together with calcium carbonate, iron oxide, silica, or hardened clay which acts as a natural cement.

Agglomerate rocks are large, coarse fragments associated with the lava flow ejected during explosive volcanic eruptions.  Although they resemble sedimentary conglomerates, agglomerates consist almost wholly of angular or rounded lava fragments of varying size and shape. Fragments are usually poorly sorted in a matrix, or appear in a mix of volcanic dust or ash that has turned to stone.

Sonder

Sonder (pronounced sonn-duh)

The realization that each random passerby is living a life as vivid and complex as one’s own. 

2012: Coined by John Koenig and thus entered English.  From the Middle French sonder, from the Old French sonder (to plumb), from sonde (sounding line), from the Old English sund ((sounding), as in sundġierd (sounding-rod)), sundlīne (sounding-line, lead) & sundrāp (sounding-rope, lead), from sund (ocean, sea), from the Proto-Germanic sundą (a swim, body of water, sound), from the primitive Indo-European swem (to be unsteady, swim) and cognate with the Old Norse sund (swimming; strait, sound).  The words which most obviously capture the meaning are probably the modern German sonder (special) and the modern French sonder (to probe).

The Dictionary of Obscure Sorrows

The Dictionary of Obscure Sorrows (Simon & Schuster (2021) pp 288, ISBN13: 9781501153648) is a multi-media project by John Koenig, encompassing a website, YouTube channel and, since 2021, a printed book.  Koenig’s purpose is to coin and define neologisms for emotions which, in English, do not have a single encapsulating word or brief phrase, the entries listed on the website and the companion volume with paragraph-length descriptions while the YouTube channel includes illustrative clips.  Koenig does not use free-form construction; not arbitrary, his words are crafted in a way not dissimilar to the manner in which English has for more than a thousand years created or absorbed words as they proved useful, his research exploring etymologies, prefixes, suffixes, and word roots.  Some may endure and some not, just how English has always evolved; for better or worse, not all tongues enjoy such linguistic promiscuity.

#freckles Opia: Looking into the eyes of Lindsay Lohan.

So there’s nothing unusual about the creation of words although in English, they’ve tended to be invented to describe new things (eg motherboard), fantastical imaginings (eg Lewis Carroll’s (1835—1898) Jabberwocky (1871)) or for literary purposes such as the whole lexicon created by Anthony Burgess (1917–1993) for A Clockwork Orange (1962).  It differs too from English’s traditional borrowing of foreign words if they do a more elegant job than that which in English demands a phrase and thus borrowed are zeitgeist (spirit of the age), schadenfreude (pleasure in the suffering of others) and fuselage (main body of an airframe).  Koenig decided to create the dictionary because, as a poet, he found the words needed to suit the rhythm of his verse simply didn’t exist.  In engineering or many other fields his approach would be uncontroversial but there may be poets (there certainly will be critics) who disapprove and suggest it’s cheating for one to create new words just because one can’t think a way to use one of the hundreds of thousands English already has.  In a similar vein, JRR Tolkien (1892–1973) criticized CS Lewis’ (1898–1963) The Lion, The Witch and The Wardrobe, the first of the seven volumes of The Chronicles of Narnia (1950–1956).  On more substantive grounds he’d issued a critique of the heavy-handed way Lewis interpolated Christian themes but his letters also reveal he rather looked down of what he thought was cheating or at least literary laziness: Tolkien took years to construct his geography; Lewis just said there was a door in the back of a wardrobe.

Shibboleth

Shibboleth (pronounced shib-uh-lith or shib-uh-leth)

(1) A belief, principle, or practice which is commonly adhered to but which is thought by some people to be inappropriate or out of date.

(2) A custom, phrase, or use of language that acts as a test of belonging to, or as a stumbling block to becoming a member of, a particular social class, profession etc.

(3) A slogan; catchword.

Circa 1300s: From the Hebrew שִׁבֹּלֶת (shibbólet) (ear of grain (the part of a plant containing grain, such as the head of a stalk of wheat or rye) (and more rarely "stream, flood or torrent")).  The word was used as a password by the Gileadites as a test to detect the fleeing Ephraimites, who could not pronounce the sound sh (Judges 12:4–6).  From this emerged by the 1630s the figurative sense of "watchword", the additional meaning "outmoded slogan still adhered to" noted by 1862.

The Ephraimites and the Gileadites

The story behind the word is in the Old Testament’s Book of Judges (12:1-15).  In ancient Hebrew, shibboleth translated literally as “ear of grain” (stream, flood or torrent in some translations), some groups pronouncing it with a "sh" sound, but speakers of related dialects pronounced it with a hard s.

In the story, two Semitic tribes, the Ephraimites and the Gileadites, fight a great battle.  The Gileadites defeat the Ephraimites, and set up a blockade across the Jordan River to catch the fleeing Ephraimites who were trying to get back to their territory.  The sentries asked each person who wanted to cross the river to say the word shibboleth. The Ephraimites, who had no "sh" sound in their language, pronounced the word with a hard s and were thereby unmasked as the enemy and slaughtered.

12:4 Then Jephthah gathered together all the men of Gilead, and fought with Ephraim: and the men of Gilead smote Ephraim, because they said, Ye Gileadites are fugitives of Ephraim among the Ephraimites, and among the Manassites.

12:5 And the Gileadites took the passages of Jordan before the Ephraimites: and it was so, that when those Ephraimites which were escaped said, Let me go over; that the men of Gilead said unto him, art thou an Ephraimite? If he say Nay;

12:6 Then said they unto him, Say now Shibboleth: and he said Sibboleth: for he could not frame to pronounce it right. Then they took him, and slew him at the passages of Jordan: and there fell at that time of the Ephraimites forty and two thousand.

As a technique to identify foreigners, the use may have predated  the biblical tale of the Gileadites and Ephraimites and there are many instances in history.  The Italians used the test-word cicera (chick pease) to identify the French during the massacre called the Sicilian Vespers (1282).

During WWII, while conducting training exercises on Pavuvu and Guadalcanal, the Marines improved battlefield security not with a password, but by an identification procedure described as "sign and countersign", the technique being sequentially to interrogate an unknown friend or foe with the name of an automobile which required the "L" sound in vocalization.  The response was required to be a cognomen for another automobile uttered in the same manner and in an accent definitely American; those who answered call out "Chryswer" or "Cadiwac" likely to be shot.

The ancient use of a shibboleth to allow the detection of enemies within was revived in 2022 during the Russian invasion of Ukraine.  Ukrainians, if suspecting someone might be a Russian, challenge them to say the word “palyanitsa”, a soft wheat bread with a crispy crust, natives of the two nations pronouncing it differently and it's said to be difficult for Russians to master the Ukrainian form.
