Didactic

Didactic (pronounced dahy-dak-tik)

(1) Something intended for instruction; instructive:

(2) Inclined to teach or lecture others too much.

(3) In art or literature, containing a political or moral message to which aesthetic considerations are subordinated.

(4) The art and science of teaching (if used with a singular verb).

(5) In medical education, of or relating to teaching by lectures or textbooks as distinguished from clinical demonstration with patients.

1635-1645: From the French didactique (fitted or intended for instruction; pertaining to instruction), a Latinized adaptation of the Ancient Greek διδακτικός (didaktikós) (skilled in teaching), from διδακτός (didaktós) (taught, learnt), past participle of didaskein (teach), from διδάσκω (didáskō) (I teach, educate), from the primitive Indo-European dens (to learn), source also of the Sanskrit dasra (effecting miracles).  The adjective autodidactic (self-taught) is from 1838, from the Greek autodidaktikos (self-taught) the construct being autos (self) + didaktos (taught).  The adjective didactic (fitted or intended for instruction; pertaining to instruction) has been in use since the 1650s while the noun didactics (the science of teaching) dates from 1836, the noun didacticism (practice of conveying instruction; tendency to be didactic in style) is attested from 1841.

In the original Greek, didacticism was a description of educational technique or content that emphasized instructional and informative qualities in literature and other types of art.  In the Hellenic tradition, the didactic signified learning in a fascinating and intriguing manner, supposed both to entertain and to instruct.  Didactic plays, of which the Greeks wrote many, were intended to convey a moral theme or other truth to the audience so the word was thus either neutral or positive.  In English, during the nineteenth century, the meaning shifted and didactic came be used as a criticism for work felt to be overburdened with instructive, factual, or other educational information, to the detriment of the enjoyment of the reader.  The use has persisted to this day and the word seems now seldom to appear without an adjective (needlessly didactic, excessively didactic, pedantically didactic, academically didactic etc).

The King's English (1997) by Sir Kingsley Amis (1922–1995), Penguin Classics, ISBN: 9780141194318, 272 pp.  Recommended to read, much fun, though not all his prescriptions should be followed.

Edgar Allan Poe (1809-1849) in his essay The Poetic Principle (1850) called didacticism “the worst of heresies”.  Kingsley Amis in The King’s English wasn’t as emphatic but was inclined to the view an author unable to succeed in their didactic purposes without boring the reader, just wasn’t a good writer.  One does wonder if he had in mind the works of his son and he was more acerbic when commenting on one of Martin Amis's interviews in which he'd said readers should really read his novels twice fully to understand them.  "That means the little shit has failed doesn't it?" observed the father.

Sabotage

Sabotage (pronounced sab-uh-tahzh (U) or sab-oh-tahzh (non-U))

(1) Any underhand interference with production, work etc, in a plant, factory etc, as by enemy agents during wartime or by employees during a trade dispute; any similar action or behavior.

(2) In military use, an act or acts with intent to injure, interfere with, or obstruct the national defense of a country by willfully injuring or destroying, or attempting to injure or destroy, any national defense or war materiel, premises, or utilities, to include human and natural resources.

(3) Any undermining of a cause.

(4) To injure or attack by sabotage.

1907: From the French sabotage from saboter (to botch; to spoil through clumsiness (originally, to strike, shake up, harry and literally “to clatter in sabots (clog-like wooden soled shoes)”).

The noun sabotage is said to have been absorbed by English in 1907, having been used as a French borrowing since at least 1903.  The sense of the French usage was “malicious damaging or destruction of an employer's property by workmen", a development from the original idea of mere deliberate bungling and inefficiency as a form of ad-hoc industrial action.  Contemporary commentators in England noted "malicious mischief" was likely the “nearest explicit definition” of sabotage before point out “this new force in industry and morals” was definitely something associated with the continent.  As the meaning quickly shifted from mere lethargy in the means to physically damaging the tools of production, the story began to circulate that the origin of the word was related to instances of disgruntled strikers (something the English were apt to ascribe as habitual to French labour) tactic of throwing their sabots (clog-like wooden-soled shoes) into machinery.  There is no evidence this ever happened although it was such a vivid image that the tale spread widely and even enjoyed some currency as actual etymology but it was fake news.  Instead it was in the tradition of the French use in a variety of "bungling" senses including the poor delivery of a speech or a poorly played piece of music, the idea of a job botched or a discordant sound, like the clatter of many sabots on as a group walked on a hardwood floor.  The noun savate (a French method of fighting with the feet) from French savate (literally "a kind of shoe") is attested from 1862 and although linked to footwear, is unrelated to sabotage.

What sabotage was depended also from where it was viewed.  In industry it was thought to be a substitute for striking in which the workers stayed in his place but proceeded to do his work slowly and badly, the aim being ultimately to displease his employer's customers and cause loss to his employer.  To the still embryonic unions seeking to organize labour, it was a reciprocal act of industrial democracy, going slow about the means of production and distribution in response to organized capital going slow in the matter of wages.  The extension by the military to describe the damage inflicted (especially clandestinely) to disrupt in some way the economy by damaging military or civilian infrastructure emerged during World War I (1914-1918).  The verb sabotage (to ruin or disable deliberately and maliciously) dates from 1912 and the noun saboteur (one who commits sabotage) was also first noted in the same year (although it had been used in English since 1909 as a French word); it was from the French agent noun from saboter and the feminine form was saboteuse.

The word exists in many European languages including Catalan (sabotatge), Czech (sabotáž), Danish (sabotage), Dutch (sabotage), Galician (sabotaxe), German (Sabotage), Hungarian (szabotázs), Italian (sabotaggio), Polish (sabotaż), Portuguese (sabotagem), Russian (сабота́ж) (sabotáž), Spanish (sabotaje), Swedish (sabotage) & Turkish (sabotaj).  Sabotage is so specific that it has no direct single-word synonym although, depending on context, related words include destruction, disruption, subversion, treachery, treason, vandalism, cripple, destroy, disrupt, hamper, hinder, obstruct, subvert, torpedo, undermine, vandalize, wreck, demolition, impairment, injury & disable.  Sabotage is a noun & verb, sabotaged is a verb & adjective, saboteur is a noun, sabotaging is a verb and sabotagable is an adjectival conjecture; some sources maintain there is no plural of sabotage and the correct form is “acts of sabotage” while others list the third-person singular simple present indicative form as sabotages.

Franz von Papen.

Although his activities as German Military Attaché for Washington DC during 1914-1915 would be overshadowed by his later adventures, Franz von Papen’s (1879–1969) inept attempts at sabotaging the Allied war effort would help introduce the word to the military vocabulary.  He attempted to disrupt the supply of arms to the British, even setting up a munitions factory with the intension of buying up scare commodities to deny their use by the Allies, only to find the enemy had contracted ample quantities so his expensive activities had no appreciable effect on the shipments.  Then his closest aide, after falling asleep on a train, left behind a briefcase full of letters compromising Papen for his activities on behalf of the central powers.  Within days, a New York newspaper published details of Papen’s amateurish cloak & dagger operations including his attempt to induce workers of Austrian & German descent employed in plants engaged in war production for the Allies to slow down their output or damage the goods.  Also in the briefcase were copies of letters he sent revealing shipping movements.

Even this wasn’t enough for the US to expel him so he expanded his operations, setting up a spy network to conduct a sabotage and bombing campaign against businesses in New York owned by citizens from the Allied nations.  That absorbed much money for little benefit but, undeterred, he became involved with Indian nationalists living in the US, arranging with them for arms to be shipped to India where he hoped a revolt against the Raj might be fermented, a strategy he pursued also with the Irish nationalists.  Thinking big, he planned an invasion of Canada and tried to enlist Mexico as an ally of the Central Powers in the event of the US entering the war with the promise California and Arizona would be returned.  More practically, early in 1915 he hired agents to blow up the Vanceboro international rail bridge which linked the US and Canada between New Brunswick and Maine.  That wasn’t a success but of greater impact was that Papen had departed from the usual practices of espionage by paying the bombers by cheque.  It was only his diplomatic immunity which protected him from arrest but British intelligence had been monitoring his activities and provided a file to the US State Department which in December 1915 declared him persona non grata and expelled him.  Upon his arrival in Berlin, he was awarded the Iron Cross.

Hopelessly ineffective though his efforts had proved, by the time Papen left the US, the words sabotage and saboteur had come into common use including in warning posters and other propaganda.  Papen went on greater things, serving briefly as chancellor and even Hitler’s deputy, quite an illustrious career for one described as “uniquely, taken seriously by neither his opponents nor his supporters”.  When one of the Weimar Republic's many scheming king-makers suggested Papen as chancellor, others thought the noting absurd, pointing out: "Papen has no head for politics."  The response was: "He doesn't need a head, his job is to be a hat".  Despite his known limitations, he proved one of the Third Reich’s great survivors, escaping purges and assassination and, despite being held in contempt by Hitler, served the regime to the end.  Even its coda he survived, being one of the few defendants at the main Nuremberg trial (1945-1946) to be acquitted (to be fair he was one of the few Nazis with the odd redeeming feature and his sins were those of cynical opportunism rather than evil intent) although the German courts did briefly imprison him, albeit under rather pleasant conditions.

The Simple Sabotage Field Manual (SSFM) was published in 1944 by the US Office of Strategic Services (OSS), the predecessor of the Central Intelligence Agency (CIA).  Its original purpose was as a resource for OSS field agents to use in motivating or recruiting potential foreign saboteurs and permission was granted permission to print and disseminate portions of the document as needed.  The idea was to provide tools and instructions so just about any member of society could inflict some degree of damage of a society and its economy, the rationale being that of a “death of a thousand cuts”.  In contrast, the more dramatic and violent acts of sabotage (high-risk activities like killings or blowing stuff up) were only ever practiced by a handful of citizens.  The SSFM was aimed at US sympathizers keen to disrupt war efforts against the allies during World War II (1939-1945) in ways that were barely detectable but, in cumulative effect, measurable and thus contains instructions for destabilizing or reducing progress and productivity by non-violent means. The booklet is separated into headings that correspond to specific audiences, including: Managers and Supervisors, Employees, Organizations and Conferences, Communications, Transportation (Railways, Automotive, and Water), General Devices for Lowering Morale and Creating Confusion & Electric Power.  The simplicity of approach was later adopted by the CIA when it distributed its Book of Dirty Tricks.

Of great amusement to students (amateur and professional) of corporate organizational behavior was that a number of the tactics the SSFM lists as being disruptive and tending to reduce efficiency are exactly those familiar to anyone working in a modern Western corporation.

Middle Management

(1) Insist on doing everything through “channels.” Never permit short-cuts to be taken in order to expedite decisions.

(2) Make “speeches.” Talk as frequently as possible and at great length. Illustrate your “points” by long anecdotes and accounts of personal experiences.

(3) When possible, refer all matters to committees, for “further study and consideration.” Attempt to make the committee as large as possible — never less than five.

(4) Bring up irrelevant issues as frequently as possible.

(5) Haggle over precise wordings of communications, minutes, resolutions.

(6) Refer back to matters decided upon at the last meeting and attempt to re-open the question of the advisability of that decision.

(7) Advocate “caution.” Be “reasonable” and urge your fellow-conferees to be “reasonable” and avoid haste which might result in embarrassments or difficulties later on.

Senior Management

(8) In making work assignments, always sign out the unimportant jobs first. See that important jobs are assigned to inefficient workers.

(9) Insist on perfect work in relatively unimportant products; send back for refinishing those which have the least flaw.

(10) To lower morale and with it, production, be pleasant to inefficient workers; give them undeserved promotions.

(11) Hold conferences when there is more critical work to be done.

(12) Multiply the procedures and clearances involved in issuing instructions, pay checks, and so on. See that three people have to approve everything where one would do.

Employees

(13) Work slowly.

(14) Contrive as many interruptions to your work as you can.

(15) Do your work poorly and blame it on bad tools, machinery, or equipment. Complain that these things are preventing you from doing your job right.

(16) Never pass on your skill and experience to a new or less skillful worker.

Lotus

Lotus (pronounced loh-tuhs)

(1) In Greek mythology, a plant believed to be a jujube or elm, referred to as yielding a fruit that induced a state of forgetfulness and a dreamy languor in those who ate it.

(2) Any aquatic plant of the genus, Nelumbo nucifera, of the water lily family, having shield-like leaves and showy, solitary flowers usually projecting above the water.

(3) Any of several water lilies of the genus Nymphaea.

(4) A decorative motif derived from such a plant and used widely in ancient art, as on the capitals of Egyptian columns.

(5) Any shrubby plant of the genus Lotus, of the legume family, having red, pink, yellow, or white flowers.

(6) An English manufacturer of lightweight sports and racing cars, best known for its successes in Formula One between 1962-1978.

1530–1540:  From the Classical Latin, lōtus or lōtos, perfect passive participle of lavō (wash), from the Ancient Greek λωτός (lōtós) (the lotus plant), the origin of which is unknown but thought probably related to Semitic plant names such as Hebrew לוט‎ (lōt) (myrrh).  The feminine was lōta, the neuter lōtum.  The circa 1500 lote was an Englished form of lotus and it survives as Lote-tree.  The yogic sense is attested from 1848.

From the 1540s, the name was, rather casually, bestowed on many plants, some related, some not even alike and that had been the pattern of the Greek lōtós which was applied to several plants before it came exclusively to mean Egyptian white lotus (a sense attested in English from 1580s), a plant prominent part in the mythology of India, Egypt, China.  The Homeric lotus later was held to be a North African shrub, from which "a kind of wine" can be made and historians conclude that was a reference to the effects rather than the taste.  The name has also been given to several species of water-lilies and a bean that grows in water.   The noun lotion is from the circa 1400 Middle English loscion (liquid preparation for application to the skin), from the fourteenth century Old French lotion, from the Latin lotionem (nominative lotio) (a washing), a noun of action from lotus (varied contraction of lavatus (a popular form of lautus, past participle of lavere (to wash) from the primitive Indo-European root leue- (to wash)).

The circa 1600 noun lotophagi (literally “lotus-eaters”) was from the Greek lotophagoi (plural), the construct being lotos + -phagos (eating), from the primitive Indo-European root bhag- (to share out, apportion; to get a share), the more common literary form of which was lotophagous.  The lotus was believed to induce a dreamy forgetfulness, hence the mention of the lotus-eater as "one who finds pleasure in a listless life" (1812) from the Greek lotophagoi, mentioned in book IX of Homer’s Odyssey.  Odysseus had to force his lethargic sailors back on board after the lotus-eaters had shared with them the narcotic fruit.  It’s one of the earliest warnings against drug use.

Of the plural

The use of plural forms in English is not consistent, though the wise attempt always to append just s or es as required.  This linguistic pragmatism (or Anglo-Saxon laziness if you prefer) simplifies things and plurals like stadia and referenda, while not extinct, are probably now archaic.  That said, plurals can sometimes need to end in an i, aux or a, often more for elegance than sticking to the rules.  Rare plurals persist because they’re useful within niche communities; scientists and statisticians being punctilious in the use of datum, the rest of us calling all such stuff, singular or plural, data.  Patterns of use in English, if of sufficient longevity (though not of necessity breadth of adoption), can re-define words borrowed from other languages.  The modern English agenda (from the Latin agenda (things that ought to be done)) is now singular, the plural being agendas and the individual components, items.  In the original, agenda was plural of agendum.  However, criterion is singular and criteria plural; any other use is a more recent lapse and remains wrong.  English is best evolving its own rules.  Lotuses isn’t pretty which is a good a reason as any for a word to vanish but under Latin rules the plural would be loti which is no better but anyway, lotus is of Greek origin.  So, because both lotos and lotus appear in the Latin texts and the plural in Greek was oi, not i, lotoi can exist in the same same documents.   That’s also why the persistent octopi is wrong and that’s a shame because it’s better than the standard English plural which is octopuses.  However, octopus comes from the Ancient Greek; the correct plural form is octopodes.

By 1968, the makers of the Lotus Formula One and sports cars responded to having their machinery called Loti and Lotaux by issuing a press release advising the company would henceforth adopt Lotus as both plural and possessive and hinted everyone should do the same.  Lotus thought all others, including the historically correct Lotuses, “horrible words”.  The press release had no effect.

The footnote: The Lotus 43

BRM H16 engine.

The change from the 1.5 litre (92 cubic inch) voiturette formula (1961-1965) to a 3.0 litre (183 cubic inch) displacement for the 1966 Formula One season meant not only would the teams need new engines but also bigger, stronger chassis.  Lotus had an advantage in solving the latter problem because it was able to modify the Lotus 38 which had won the 1965 Indianapolis 500 when fitted with a 4.2 litre (256 cubic inch Ford V8).  The 38 was a strong and adaptable design, many of the elements of which would be incorporated into the later Lotus 49 and many racing cars of the era were to some extent Lotus 38 clones.  For an engine, for a number of reasons, Lotus choose to use the BRM H16, a unit created by reconfiguring the successful 1.5 litre BRM V8 into a 180^o (flat) configuration and mounting one atop another, thereby creating a 3.0 litre H16 which had the advantage of a relatively short development cycle because so many existing components were able to be used but the drawbacks were weight, size and height.

BRM H16 in Lotus 43.

Although commendably short, the H16 was tall which meant a high centre of gravity, something exacerbated by having to mount the block high in the chassis to permit sufficient clearance for the exhaust systems of the lower banks of cylinders.  It was also wide, too wide to fit into a monocoque socket and thus was taken the decision to make the engine an integral, load-bearing element of the chassis.  There was no other choice but that aspect worked well.  Had the H16 had delivered the promised horsepower the Lotus 43 might have been a success but the numbers were never realized.  The early power output was higher than the opposition but it wasn’t enough to compensate for the drawbacks inherent in the design and, these being so fundamental they couldn’t be corrected, the only hope was even more power.  The path to power was followed and modest increases were gained but it was never enough and time ran out before the plan to go from 32 to 64 valves could come to fruition, an endeavor some suggested would merely have “compounded the existing error on an even grander scale.”  Additionally, with every increase in power and weight, the already high fuel consumption worsened.

Lotus 43, US Grand Prix, Watkins Glen, 1966.

In winning the 1966 US Grand Prix at Watkins Glen, the Lotus 43 delivered the H16 its sole victory, something BRM never managed when the engine was mounted in their chassis.  The 1.5 litre BRM V8 had enjoyed outstanding reliability but of the forty times the H16 started a race, twenty-seven ended prematurely.  The irony of the tale is that in the two seasons BRM ran the 400 horsepower H16 with its sixteen cylinders, two crankshafts, eight camshafts and thirty-two valves, the championship in both years was won by the Repco-Brabham, its engine with 320 horsepower, eight cylinders, one crankshaft, two camshafts and sixteen valves.  Adding insult to the exquisitely bespoke H16’s injury, the Repco engine was based on an old Oldsmobile block which General Motors had abandoned several year earlier (the engine blocks used by Brabham could be purchased by any customer for around US$20, a number which must have astonished outfits like Scuderia Ferrari).  After two seasons the H16 venture was retired, replaced by a conventional V12; Lotus sold the two 43s to a privateer who installed 4.7 liter (289 cubic inch) Ford (Windsor) V8s and campaigned them in Formula 5000 events.  The new Lotus 49 used the 3.0 litre Ford Cosworth (DFV) V8, a combination which enjoyed, remarkably, three successful seasons.

Orifice

Orifice (pronounced awr-uh-fis or or-uh-fis)

A mouth, opening or aperture, as of a tube or pipe; a mouth-like opening or hole; mouth; vent (mostly technical or medical use).

1535–1545: From the Middle English orifice (an opening, a mouth or aperture), from the Old French & Middle French orifice (the opening of a wound), from the Late Latin ōrificium (an opening (literally "the making of a mouth")), the construct being Latin ōr- (stem of ōs (genitive oris)) (mouth (and related to "oral")) + fic- (combining form of facere; facio) (to make, to do) + -ium (the noun suffix).  The root of facere was the primitive Indo-European dhe- (to set, put).  The rare adjectival form is orificial; neither orificish or orificesque apparently exist.

Miss Schilling’s Orifice

Rolls-Royce Merlin V12.

Fuel to early versions of the twenty-seven litre (1648 cubic inch) Rolls-Royce Merlin V12 engine was supplied with a carburetor, putting the pilots in the Merlin-powered Spitfires and Hurricanes at a disadvantage against the German Messerschmitt BF109 fighters which used a fuel-injected Daimler-Benz DB601 inverted V12.  In the British planes, during a negative G-force maneuver (pitching the nose hard down), fuel was forced upwards to the top of the carburetor's float chamber rather than into the combustion chamber, leading to a loss of power. If the negative G continued, the fuel would collect in the top of the float chamber, forcing the float to the bottom. This in turn would open the needle valve to maximum, flooding the carburetor with fuel, drowning the supercharger with an over-rich mixture which would shut down the engine, a serious matter in aerial combat.

Battle of Britain era Hawker Hurricane Mk IIA and Supermarine Spitfire Mk II.

Ms Beatrice “Tilly” Shilling (1909-1990) was a pre-modern rarity, a female engineer and amateur racing driver.  While employed as an engineer at the Royal Aircraft Establishment (RAE) at Farnborough she worked on the fuel delivery problem, concluding quickly the only complete solution for fuel starvation was a pressurized fuel system such as the direct injection on the Daimler-Benz V12s but that such a development would take months to design, test, manufacture and install.  However, as a stop-gap measure, she designed a flow restrictor: a small metal disc with a central orifice, looking much like a plain metal washer.  The restrictor orifice was sized to accommodate just the fuel flow needed for maximum engine power, the setting usually used during dogfights and it solved the immediate, critical, problem of the engine shutdowns following flooding.  Officially named the RAE Restrictor or RAE Anti “G” Carburetor, the device proved popular with pilots, who much preferred to call it Miss Shilling's orifice or the Tilly orifice.  The simple and elegant solution proved effective until pressurized carburetors (essentially throttle-body injection, a simplified version of the Daimler-Benz direct fuel injection) were developed which permitted even inverted flight.  With a backpack of RAE Restrictors, she toured RAF airfields on her motor-bike instructing and assisting the maintenance crews with the installation of the devices.

Ms Shilling was a serious engineer making an important contribution to the war effort and was not amused by the nick-names for her invention but reportedly regarded it as something typical of minds of men and carried on with her work.  The orifice was but a footnote in the history of the Merlin and the Allied war effort but did typify the improvisation and speed with which British industry developed "quick & dirty" solutions, especially in the early days of the war.

Demodex

Demodex (pronounced dem-ah-deks or dem-oh-deks)

A genus of parasitic, usually nonpathogenic, mites that invade the skin and are usually found in humans in the sebaceous glands of the face and hair follicles.

1839: First noted in the scientific literature in the publications of Richard Owen (1804–1892), a comparative anatomist and palaeontologist.  Name is said to be a construct of scientific Latin, from the ancient Greek δημός (dēmos) (fat) of unknown origin + the Byzantine Greek δήξ (dëx) (woodworm) of unknown origin.

Of the six dozen-odd known species, two live on human faces: Demodex folliculorum and Demodex brevis, both often referred to as eyelash mites.  A majority of humans are infested with Demodex, so it’s endemic but usually harmless except for a few where a range of skin diseases (called demodicosis) can eventuate.  Because most people asymptomatically co-exist with the creatures, some biologists once classified them an example of commensalism rather than parasitism but the modern scientific consensus is they must be considered parasitic.  

Demodex folliculorum was first described in 1842, Demodex brevis identified as distinct only in 1963, the former found in hair follicles, the latter in the sebaceous glands connected to these follicles, both inhabiting areas mostly near the nose, eyelashes, and eyebrows.  Adult mites are a tiny 0.3–0.4 mm (0.012–0.016 inch) long with Dempdex brevis slightly shorter than Demodex folliculorum.  Each has a semi-transparent, elongated body consisting of two fused segments with eight short, segmented legs attached to the upper part.  The body is covered with scales for anchoring in the hair follicle, and has pin-like mouthparts for eating skin cells and oils which accumulate in the follicles.  Preferring to avoid light, at night, they do move from the follicles, walking slowly across the skin, sometimes transferring between people through contact with hair, eyebrows, and the sebaceous glands of the face.

Females are larger and rounder than males, both sexes having a genital opening and fertilization is internal.  Mating is done in the follicle opening, eggs being laid inside the hair follicles or sebaceous glands.  The six-legged larvae hatch after three to four days and become adults in about seven days.  A typical lifespan is five-seven weeks.

In your face.  You’re never alone with a Demodex.

Hexakosioihexekontahexaphobia

Hexakosioihexekontahexaphobia (pronounced hex-ax-oh-gee-oh-e-eye-hex-en-gen-too-hex-a-pho-be-ah)

Fear of the number 666.

The number 666 is best known from the New Testament’s Book of Revelation (13:15–18) and is a symbol both of the Antichrist and the Devil and is applied to the second of two beasts mentioned in the Book of Revelation.  The construct was the Ancient Greek ἑξακόσιοι (hexakósioi) (six hundred) + ἑξήκοντα (hexḗkonta) (sixty) + ἕξ (héx) (six) +‎ -phobia.  The suffix -phobia (fear of a specific thing; hate, dislike, or repression of a specific thing) was from the New Latin, from the Classical Latin, from the Ancient Greek -φοβία (-phobía) and was used to form nouns meaning fear of a specific thing (the idea of a hatred came later).  For certain historians and biblical scholars for whom 616 is as suspect as 666 there's the companion phobia: Hexakosioihekkaidekaphobia.   The related forms are hexakosioihexekontahexaphobe & hexakosioihexekontahexaphobic.  For help when practicing pronunciation, go to:

The number of the beast

The origin is murky and there are other biblical references but not always as 666; 666 is the number of talents of gold Solomon collected each year and is the number of Adonikam's descendants who return to Jerusalem and Judah from the Babylonian exile and scholars suggest there are latent references in transliteration.   Nebuchadnezzar, the sixth-century BC king of Babylon, appears both as Nebuchadrezzar and Nebuchadrezzur and the number of each name can be calculated because in the Hebrew, letters double as numbers.  Nebuchadrezzar is 663, and Nebuchadrezzur, 669; midway between the two lies 666 and it was Nebuchadrezzar, who came (bidden by God) to crush God's people so may thus prefigure the end of times beast, the antagonistic creature which appears briefly about two-thirds into Revelation’s apocalyptic vision. Some manuscripts of the original Greek use the symbols χξϛ or χξϝ while other manuscripts spell out the number in words.  Using gematria (the method of calculating numbers from names), Nero Caesar transliterated from Greek into Hebrew produces the number 666 whereas the Latin spelling renders 616.  Thus, 666 may be a coded reference to Nero, although that notion does depend on the accepted Hebrew spelling of Caesar, a thing about which there’s some doubt. 

For two millennia there’s never been ecclesiastical or scholarly consensus about 666.  Although the second century Greek cleric Irenaeus affirmed 666, theologians then and since have expressed doubts because of the appearance of 616 in the Codex Ephraemi Rescriptus, one of the four great uncial codices, as well as in the Latin version of Tyconius and an ancient Armenian version.  Irenaeus knew about 616 but choose, for whatever reason, to correct the Vetus Latina, the existing Latin version of the New Testament.  The oldest known manuscript of Revelation, from Papyrus 115 in the Oxyrhynchus series, uses 616, as does the later Codex Ephraemi Rescriptus, even having 616 written in full: ἑξακόσιοι δέκα ἕξ, hexakosioi deka hex (six hundred and sixteen).  These documents are cited by some scholars who suggest 616 was the original, 666 substituted by analogy with 888, the Greek number for Jesus. 

More fun, and just as speculative, is the idea the writers of the time just liked numbers, 666 being more interesting than 616 because:

(1) 666 is a triangular number, the sum of the first 36 natural numbers (ie 1+2+3+4+5+6+...+36=666).  That of course makes 666 the sum total of the numbers on a roulette wheel.  Zero, so often of such significance, here has no effect. 

(2) 666 is the sum of squares of the first seven prime numbers.

(3) In Roman numerals 666 is DCLXVI which has exactly one occurrence of all symbols whose value is less than 1000 in decreasing order (D=500, C=100, L=50, X=10, V=5, I=1).

(4) In base 10, 666 is a repdigit (and therefore a palindromic number) and a Smith number.  A prime reciprocal magic square based on 1/149 in base 10 has a magic total of 666.

The Number of the Beast is 666 (circa 1805), pen and watercolor, by William Blake (1757-1827).

Thanks to popular culture, even beyond Christendom, the number 666 and its relationship with the Devil and the Antichrist is well known and it clearly affects a few.  When in 1989 Ronald Reagan (1911-2004 US president 1981-1989) retired to leafy rich Bel-Air in Los Angeles (a locality which maintained its prestige despite the indignity of the Chevrolet Bel Air between 1950-1972 being reduced from a premium to a basic designation), although happing with the house at 666 St Cloud Road, they soon had the address changed to 668.  Whether this was on advice from Nancy Reagan’s (1921-2016) clairvoyant isn’t recorded but some organs of the US state also chose not to take chances.  US Route 666 (dating from 1926), upon statistical analysis, proved unusually dangerous and after this became public knowledge it picked up the nickname the Devil’s Highway.  In 2003 it was renamed US Highway 491 and the accident rate has lowered although its thought this is due to improvements to the road and a reduction in the number of people stopping to steal road signs, Route 666 a popular destination for stoners to pose for photographs, a thing even in the pre-selfie era.  In more secular Finland, there was apparently little concern, Finair flight AY666 plying the CPH-HEL (Copenhagen-Helsinki) route between 2006-2017, AY666 retired and replaced by AY954 as part of a general restructuring.  AY666’s last flight was on a Friday the 13^th (for the 21^st time) and it landed safely, eight minutes ahead of schedule.

Names for many phobias have been coined and while some (relating to injections, spiders, heights etc) are of clinical significance in mental health, many have been created just for linguistic fun.  A surprising number relate to numbers, many of which reference popular culture (TV, video games etc) and a site exists which provides a précis of many.  The overarching condition is arithmophobia (also known as numerophobia), which is a fear of numbers or mathematics but among the specifics there are:

Just because a "phobia" appears in a list doesn't mean it "exists" in a clinical sence; there are doubtless many listed "phobias" which have never afflicted a single individual, their coining simply because someone decided to prove it was possible and an AI bot presumably could create many more.  Indeed, because of the infinite number of numbers, the number of potential "number phobias" is similarly infinite.  Some though may be real henophobia (fear of 1) is said to compels sufferer to avoid being associated with “doing something once”, being the “first in the group” etc) while eikosiheptaphobia (fear of 27) is a pop-culture thing which arose in the early 1970s when a number of rock stars died messy, drug-related deaths at 27).  Presentations of patients with tessarakontadyophobia (fear of 42) may have spiked in patients after the publication of Douglas Adams’ (1952–2001) Hitchhiker's Guide to the Galaxy (1979-1992) but enenekontenneaphobia (fear of 99) is thought unrelated to the Get Smart TV series of the 1960s.  Tetrakosioeikosiphobia (fear of 420) is a syndrome restricted presumably to weed-smokers in the US although it could also be a thing among those with a morbid dread of 4 February or 20 April (depending on where one lives) and although heftakosioitessarakontaheptaphobia (fear of 747) may have had something to do with the Jumbo Jet, with the withdrawal from passenger service of the tough, reliable (four engines and made of metal) Boeing 747 and its replacement by twin-engined machines made increasingly of composites and packed with lithium-ion batteries, a more common fear may be “not flying on a 747”).  Closer to earth, enniakosioihendecaphobia (fear of 911), in the US may be a co-morbidity with tetrakosioeikosiphobia or suffered by those with a bad experience with a pre-modern Porsche 911 which, in inexpert hands, could behave as one would expect of a very powerful Volkswagen Beetle.  The rare condition nongentiseptuagintatrestrillionsescentiquinquagintanovemmiliacentumtredecimdeciesoctingentivigintiquattuormiliatrecentiphobia (fear of 973,659,113,824,315) was almost certainly one of those coined as a linguistic exercise.  The marvellous Wiki Fandom site and The Phobia List are among the internet’s best curated collection of phobias.

Phobias can be coined ad-hoc.  In 2008, Time magazine pondered lindsayphobia.  

The only one which debatably can’t exist is neonumerophobia (fear of new numbers) because, given the nature of infinity, there can be no “new numbers” although, subjectively, a number could be “new” to an individual so there may be a need.  Sceptical though mathematicians are likely to be, the notion of the “new number” has (in various ways) been explored in fiction including by science fiction (SF or SciFi) author & engineer Robert A Heinlein (1907–1988) in The Number of the Beast (1980), written during his “later period”.  More challenging was Flatland: A Romance of Many Dimensions by English schoolmaster & Anglican priest Edwin Abbott Abbott (1838–1926) which was published under the pseudonym “A Square”, the layer of irony in that choice revealed as the protagonist begins to explore dimensions beyond his two-dimensional world (in Victorian England).  Feminists note also Ursula K Le Guin’s (1929–2018) The Left Hand of Darkness (1969) in which was created an entirely new numerical system of “genderless" numbers”.  That would induce fear in many.

The latest edition of the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR, March 2022) made few changes to the classification anxiety disorders and phobias which had been revised in DSM-5 (2013).  Phobias are categorized as anxiety disorders, with specific phobia (fear of something that poses little or no actual danger) being the most common anxiety disorder.  A specific phobia is said to manifest when a person experiences extreme anxiety when they anticipate exposure or are exposed to a feared stimulus and there are five general categories: (1) animal type (spiders, snakes, dogs etc), (2) the natural environment (tornadoes, heights, water, fire etc), (3) injections and related procedures (needles, medical procedures), (4) situational events (flying, enclosed spaces etc ) & (5) other types (ie phobias that do not fit into the previous four categories).  The fifth category interacts with the introduction of Generalized Anxiety Disorder (GAD) which is diagnosed when an individual experiences persistent worry about everyday challenges out of proportion to the perceived threat.  GAD extends to those aware their reaction is one of excessive fear about what can be a non-existent threat and no more than worrying about worrying too much.  Superstitions related to particular numbers are common in many cultures but of themselves these do not constitute a phobia which technically is a diagnosis of reaction to the point where the affect on a patient’s life is clinically significant.  Accordingly, while noting just about anything which has been styled a phobia could induce a case of GAD, few actually satisfy the APA’s diagnostic criteria and the DSM mentions just the handful which constitute the overwhelming majority of cases.
