1400–1450: From the late Middle English, the construct being fish + tail.  Fish the noun (strictly a vertebrate which has gills and fins adapting it for living in the water but the word came to be more widely applied, zoologically) was from the Middle English fisch, from the Old English fisċ (fish), from the Proto-West Germanic fisk, from the Proto-Germanic fiskaz (fish) (source also of the Old Saxon, the Old Frisian & the Old High German fisc, the Old Norse fiskr, the Middle Dutch visc, the Dutch vis, the German Fisch & the Gothic fisks) and related to the West Frisian fisk, the Danish, Norwegian & Swedish fisk, the Irish iasc & the Latin piscis; Root probably either the primitive Indo-European peysḱ- (fish) or pisk (a fish) but at least one etymologist, on phonetic grounds, has suggested it might be a northwestern Europe substratum word.  Fish the verb is from the Old English fiscian (to fish, to catch or try to catch fish), and was cognate with the Old Norse fiska, the Old High German fiscon, the German fischen & the Gothic fiskon, all derived from the noun.  In popular use, since Old English, fish has been used to apply to "any animal that lives entirely in the water," hence shellfish & starfish although, in English there’s an early fifteenth century document which describes fishes bestiales as "water animals other than fishes").  Today, aquatic mammals like dolphins are presumed fish by some.  The plural is fishes, but in a collective sense, or in reference to fish meat as food, the singular fish is commonly used as a plural so, except for the pedants, that battle is lost.  Regarding the heavens, the constellation Pisces is from the late fourteenth century.  The hyphenated form fish-tail is common.  Fishtail is a noun & verb and fishtailing & fishtailed are verbs; the noun plural is fishtails.  Presumably, were one to be employed to chop the tails off fish, one would be called a "fishtailer" but the term seems never to have been used.

Tail was from the Middle English tail, tayl & teil (hindmost part of an animal), from the Old English tægl & tægel (tail), from the Proto-Germanic taglaz & taglą (hair, fiber; hair of a tail) (source also of the Old High German zagal, the German Zagel (tail), the dialectal German Zagel (penis), the Old Norse tagl (horse's tail) and the Gothic tagl (hair), from the primitive Indo-European doklos, from a suffixed form of the roots dok & dek- (something long and thin (referring to such things as fringe, lock of hair, horsetail & to tear, fray, shred)), source also of the Old Irish dual (lock of hair) and the Sanskrit dasah (fringe, wick).  It was cognate with the Scots tail (tail), the Dutch teil (tail, haulm, blade), the Low German Tagel (twisted scourge, whip of thongs and ropes; end of a rope), the dialectal Danish tavl (hair of the tail), the Swedish tagel (hair of the tail, horsehair), the Norwegian tagl (tail), the Icelandic tagl (tail, horsetail, ponytail), and the Gothic tagl (hair). In some senses, development appears to have been by a generalization of the usual opposition between head and tail.  The OED (Oxford English Dictionary) suggested the primary sense, at least among the Germanic tongues, seems to have been "hairy tail," or just "tuft of hair," but already in Old English the word was applied to the hairless "tails" of worms, bees etc.  The alternative suggestion is that the notion common to all is that of the "long, slender shape."  It served as an adjective from the 1670s.  A long obsolete Old English word for tail was steort.

An unmistakable look, the “fishtail tip” polarizes opinion; it really is a “love it or hate it” fitting but they retain great popularity in the Harley Davidson community, a crew as devoted to their machines as any.  There are many modern takes on the design; while all feature the characteristic vertical, narrow flare in the distinctive shape, many are upswept and some protrude from the back more than others.  As well as the look, fishtails often are advertised on the basis of their sound (loud) and internally, are tuned to create different resonances, the ears of Harley Davidson riders as sensitive to the variations as are collectors of Stradivarii.

1937 Norton Model 30 International with Brooklands Can (technically the Brooklands Silencer) (left) and 1934 MG Magnette 'K3' Specification Supercharged Roadster (right).

One of the world’s first dedicated venues for motorsports and aviation, England’s Brooklands motor racing circuit was built in 1907, predating the IndianapolisMotor Speedway by two years.  Located in what had until then been the quiet little hamlet of Weybridge in the county of Surrey, some 20 miles (12 km) south-west of London, it sits 9 miles (14.5 km) south of Heathrow Airport and a portion of the original outer circuit (originally 2.75 miles (4.4 km) in length with the banking in places rising almost 30 feet (9.1 m) high) still exists.  Then, as now, Motorsport was a very noisy business and as the sport boomed in popularity after World War I (1914-1918), the tolerance of the inhabitants of Weybridge must have been tested because there’s a record of complaints about the noise (especially on Sundays and during the 24 hour events sometimes run) and eventually, in September 1924, a group commenced in the High Court an action in the tort of nuisance.  By July 2025 (reasonably brisk by the standards of the legal system), a settlement was agreed which included a permanent injunction limiting the days and hours of operation and the creation of the novel “Brooklands Can”, a design of muffler which could be adapted to both cars and motorcycles.  Were it created today, it'd likely be dubbed the “Brooklands Nimby” (not in my backyard).

What the High Court’s injunction required was even on those days when racing was allowed, noise levels had to be reduced and the obvious solution was a muffler (in England then known optimistically as “silencers”) and the case turned out to be influential as the century progressed, often cited as the way a court might balance technological progress, any public nuisance created and the right of individuals to the “quiet enjoyment” of life in their homes.  Interestingly, the French (silencieux) and Italians (silenziatore) followed the English practice while the more practical Germans adhered to the realistic literalness of the Americans with Schalldämpfer (sound damper).  All Brooklands cans had two distinguishing characteristics: a rhomboidal receptacle located close to the engines header pipes which emerge from the exhaust manifold and a fishtail tip (although those used on some smaller capacity cars did terminated in a straight “dump pipe” and depending on the displacement (and thus the volume of exhaust gasses), the dimensions of the apparatus varied.  The “silencer” didn’t make the machines “quiet” in the accepted sense of the word; just less noisy.

Tilly Shilling on her Norton N30 500, Brooklands, July 1935.  Note the fishtail Brooklands Silencer.

Ms Beatrice “Tilly” Shilling (1909-1990) was a pre-modern rarity, a female engineer and amateur racing driver.  Even before gaining a MSc (Master of Science) in mechanical engineering, Ms Shilling had been building and racing motorcycles and it was on her modified (at one point even fitting a supercharger) 490 cm³ Norton M30, she lapped the Brooklands track at 106 mph (171 km/h), a feat for which she was awarded the BMRC (British Motorcycle Racing Club) Brookland Gold Star; she remains only one of three women to have lapped the famous banked circuit “at the ton” before it was closed in 1939.  With the coming of war, she returned the Norton to road use, riding in this form until 1953.

Battle of Britain (1940) era Hawker Hurricane Mk IIA (upper) and Supermarine Spitfire Mk II (lower).

In 1940, while employed as an engineer at the RAE (Royal Aircraft Establishment) at Farnborough, Ms Shilling worked on the "fuel delivery problem" reported by RAF (Royal Air Force) Fighter Command pilots, the Rolls-Royce Merlin V12s in their Hurricanes and Spitfires "cutting out" for as long as 1½ seconds during a "negative G-force maneuver" (pitching the nose hard down), the fuel being 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.  While 1½ seconds doesn't sound long, in combat at altitude, travelling at hundreds of mph, inches and seconds can be critical: the difference between life and death.  The complete solution for fuel starvation was a pressurized fuel system such as the direct injection used by Daimler-Benz 600-series inverted V12s as used in the German fighters but such a development would take months to design, test, manufacture and install.

RAE Anti "G" carburetor restrictor plate instruction sheet.

As a stop-gap measure, Ms Shilling 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 the same Norton N30 500 on which she'd once lapped Brooklands at 100 mph, 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 nicknames for her invention but, reportedly regarded it as something typical of minds of men, rolled her eyes 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.

1933 Napier-Railton.

Driven by John Cobb (1899–1952), this car in 1935 set the Brooklands lap record for the Outer Circuit at 143.44 mph (230.84 km/h) a mark which will stand for all time because after being appropriated in 1939 for military purposes, the facility never re-opened.  The Napier-Railton was powered by a W12 (the so-called “broad arrow”) aero engine of 24 litres (1,461 cubic inch) and because the configuration had the cylinders in three banks of four, three of the Brooklands Cans had to be fitted and, with each bank displacing some 8 litres (487 cubic inch), each system was among the largest ever built.  Away from the delicate ears and aspidistras of Surrey's respectable residents, the machine sometimes ran “unsilenced”, including on the Bonneville Salt Flats where it ran with nothing more open stack exhausts, setting a world 24 hour record at an average speed of 158.6 mph (242 km/h).

The sense in common law of tail (limitation of ownership) which endures mostly in the law of real property began as a legal term in English in the early fourteenth century (late thirteenth in Anglo-French & Anglo-Latin); in almost all cases it was a shortened form of entail.  The verb tail dates from the 1520s and was derived from the noun, the sense originally "attach to the tail", the meaning "move or extend in a way suggestive of a tail" dating from 1781.  The meaning “secretly to follow" is a US colloquial creation from 1907, borrowed from the earlier sense of "follow or drive cattle”.  The saying "tail off” (diminish) was noted in 1854.  The tail of a coin (reverse side; opposite the side with the head, hence “heads or tails”) appears to have been first described that was in the 1680s.  The more predictable "backside of a person, buttocks" is recorded from circa 1300, the slang sense of "pudenda" is from the mid-fourteenth century and as a term to refer to an “act of copulation with a prostitute”, it was first noted in 1846.  From circa 1933 it was applied to mean "woman as sex object" is from 1933.  In printing and typography, tail was the technical term to describe the descending strokes of letters from the 1590s.  As “tails”, the formal dress for men (coat with tails), the first advertisements appeared in 1857.  The tail-race, the part of a mill race below the wheel is from 1776.  The phrase “to turn tail” (take flight) dates from the 1580s and was originally from falconry, later to be adopted by the Admiralty and the army.  The image of the “tail wagging the dog” (a minor or secondary part of something which is controlling or dominating the whole or the main part) is from 1907 and was part of the jargon of political science.

Among the most photographed “fish tails” are those of whales, once hunted for their meat and oil, they’re now charismatic creatures and among nature’s most prolific content providers, their tails “fluking” (appearing above the surface just as a deep dive is about to begin) long an Instagram staple.  Whales are however not fish, all being mammals, they’re thus within the zoological class Mammalia, not Pisces.  The “whale tail” spoiler first appeared on Porsches in 1974 and is best remembered for its use on the 911 Turbo (930, 1974-1989), a vehicle which gained the nickname “widow-maker” because, in unskilled hands, the quirky handling (the 930 wasn’t exactly a “250 horsepower VW Beetle” but the layout was the same and the inherent characteristics thus exaggerated although (up to a point), well-tamed) could lead to “fishtailing” and worse.  The “whale tail” later evolved into the “tea tray” although the original nickname remains more widely used, even of later variants.

The event's “dress code” for 2026 was “fashion is art” though at the Met Gala it's more “suggested theme” than enforced code and designers have always interpreted things liberally.  That liberality sometimes has assumed such a level of abstraction that Met Gala outfits have defied attempts to see a link with the code but Ms Delevinge’s fishtail gown with delicate appliqués was a tribute to the art of the seamstress.  Quite when a “fishtail” becomes a “train” may be in the eye of the beholder but a photographer staging shots on the Met’s staircase could arrange the fabric in ways to produce either effect.

Fish appears often in idiomatic use.  The figurative sense of “fish out of water” (a person in an unfamiliar and awkward situation) is attested from the 1610s, the use extended from circa 1750, usually with a modifier (strange fish, queer fish, cold fish) but from at least 1722 it was used in reference to a person considered desirable to “catch”, a sense preserved in the phrase “plenty more fish in the sea”, a form picked up by one dating site.  To “drink like a fish” (one with a habitually high consumption of alcohol) is from 1744 and the “fishy story” (an incredible or extravagant narration) was first noted in 1819, a US colloquial form based on the tendency of anglers to exaggerate the size of “the one that got away”.  Having “other fish to fry” (having other things which demand one’s attention) is from the 1650s.  In optics, the fish-eye lens was patented in 1959.  Fish-and-chips seem first to have been advertised in 1876 and fish-fingers were first sold in 1962.

A fitted bodycon construction, the distinguishing feature of the fishtail dress is the flowing, scalloped hemline, often longer at the back and tending to flare from around the knee-line.  Because a successful implementation of the style depends most on length and volume, most fishtail dresses are floor length, many better described as gowns although some have tried shorter variations.  The bodice can vary but fitted waists are the most frequently seen.  The design was originally called the "fishtail train" and the early versions, first seen in the 1870s, all featured the asymmetric extension at the back and it wasn’t until the turn of the century the flaring lowered from mid-thigh to the knee.  Prior to the Victorian era, trains were not unknown but they were then worn only as evening gowns and were really an addition to existing garments.

Some in the industry refer to the “fishtail” as the “trumpet” or the more charming mermaid and there are those who insist on distinguishing between the three, based usually from the point at which the flare begins but the distinction escapes the many who use the terms interchangeably, regarding all as variations on a theme.  However described, the great advantage of the lines is that they create, on a suitable frame, an hourglass figure and one with a range of definition, all determined by the point at which the flare begins and the volume of material chosen for the fishtail; done properly it can render a feminine and flawless silhouette, perhaps the most persuasive reason it’s chosen by so many brides.  Some however are probably too easily persuaded, the fishtail really not suited to those either too short or too wide.  Successfully to wear a fishtail, it’s not necessary to be truly statuesque or actually thin but beneath a certain height, one starts to look like part of a condiment set; one must be realistic about what shapewear can achieve.  The recommendation is that the style can be worn by those of at least average height and it works best on those who are slim with small or medium size hips.  A good seamstress can adapt things to better suit other shapes but there’s a law of diminishing returns the more one is removed from the ideal; a deep but narrow cut can disguise only so much.

Fishtail braid in blonde.

The fishtail braid is a variation of the French braid, both with a smoothly woven appearance, the fishtail dividing the hair into two sections instead of the French three.  The technique essentially is that a small piece of each section is passed over to the other, the process repeated until the braid assumes its shape; in the nineteenth century this was known as the "Grecian braid".  The fishtail braid appears intricate because it's built with small strands but hairdressers say it's a simple, and essentially repetitive, nine-step process.  On great advantage of the fishtail is it lends itself well to a looser braid, one which over a couple of days will tend usually (and gradually) to deconstruct into a deliberately messy look, the attraction is technical as well as aesthetic: the messy fishtail is uniquely suited to act as a framework for hair extensions.

(1) Split the hair into two equal strands

(2) Pick up a small section of hair on the right side of the right strand

(3) Cross the small section over and add it to the left strand

(4) Pick up a small section of hair on the left side of the left strand

(5) Cross the small section over and add it to the right strand

(6) Pick up a small section of hair on the right side of the right strand

(7) Cross the small section over and add it to the left strand

(8) Pick up a small section of hair on the left side of the left strand

(9) Cross the small section over and add it to the right strand

(10) Repeat steps 2-9 until the end is reached.

Students and their mannequins, Pints & Ponytails, London, March 2026.  Presumably, there would be some inverse correlation between symmetry of braids and consumption of pints of beer.  As a quirk of English, while one doing the braiding is a braider, there is no companion word braidee for the one being braided; the same convention applies to plait.

Braiding and platting of hair has for some time been political because certain styles are claimed to have specific cultural or religious connections so anyone not of the background adopting those looks risk being accused of a gamut of offences ranging from microaggression to cultural appropriation.  Recently, the braid has also entered the “toxic masculinity” debate after self-proclaimed misogynist Andrew Tate (b 1986 and dubbed by some the “high priest of toxic masculinity”) disapprovingly shared a video from a “Pints and Ponytails” event in London.  The novel P&Ps are conducted to train men in the art of creating their daughters’ braids, plaits and pony-tails, something which to most probably doesn’t look challenging until they make an attempt and find out it’s something of an art, the tresses just one component in a process which extends also to the mysteries of pins, brushes, detangler spray, leave-in conditioner and hair-ties.

A recent victim of inexpert braiding: More practice required.

To hairdressers, braids and plaits are a “basic style” taught to entry-level apprentices, but even for those familiar with tasks such as stranding cables, early results are likely to be disappointing; to assure those concerned, no daughter was damaged by the neophyte stylists, the P&P sessions conducted using the same mannequins salons use in their training.  The courses have proved popular with men as might be expected of any event including pints of beer but the serious rationale was an attempt to improve bonding between fathers and daughters as well as increasing the participation of men in child-raising chores.  As the organizers expected, the sessions also provided a time and place in which men could discuss the problems and challenges of fatherhood, the unique environment of drinking beer while learning to plait tending to encourage conversation on topics probably not often raised in situations where men gather; in other words, the sort of discussions familiar to young mothers.  Cultural critic Andrew Tate cast aspersions on the masculinity of the men taking part although one might have thought he’d see benefits in women being relieved of responsibility for the daily pony tail(s), thereby leaving them more time for cooking & cleaning.

Tenebrous

Tenebrous (pronounced ten-uh-bruhs)

Dark; gloomy; obscure.

1375-1425: From the late Middle English tenebrose (full of darkness, gloomy), from the Anglo-Norman tenebrous (the earlier spelling was tenebrus), from the eleventh century Old French tenebros (dark, gloomy) (which endures in modern French as ténébreux), from the Latin tenebrōsus (dark), from tenebrae (darkness, shadows).  The Latin forms may have been dissimilated from the earlier temebrai, from the primitive Indo-European root temsro- (dark), an adjective from temos- (darkness).  The adjective tenebrous indicates a high degree of darkness but not an absolute absence of light, the comparative is thus more tenebrous and the superlative most tenebrous.  Tenebrous is now a literary word valued by poets because of the relative novelty of the rhyming and is used also figuratively (as early as the 1670s it was deployed to suggest someone was “morally or mentally dark”.  Tenebrous, tenebricose & tenebrific are adjectives, tenebrity, tenebrousness & tenebrosity are nouns and tenebrously is an adverb; the noun plural is tenebrosities.  The alternative spelling is tenebrious and except in literary use, the verb tenebrize is now obsolete.

Salomè con testa del Battista (Salome with the Head of John the Baptist, circa 1608), oil on canvas by Caravaggio (Michelangelo Merisi da Caravaggio; 1571–1610), National Gallery, London.

Tenebrosity (darkness, gloom, obscurity) was from the early fifteenth century, tenebrious (pertaining to darkness, of a dark nature) dates from the 1590s, tenebrity (quality of being dark) was in use by at least 1792 while tenebrific (producing darkness), dating from the late 1760s, was implied in the earlier tenebrificating, recorded in 1743.  In 1818, it was reported in a London publication there was a theory darkness was not simply the absence of light, but that certain heavenly bodies (called Tenebrific Stars), emitted rays of positive darkness, which produced what commonly was called “night”.  This is how science evolves, theories existing to compete as explanations for this and that until disproved.  The early fifteenth century Tenebrer (bearer of darkness) was an epithet of Satan.  One variant which didn’t endure was recorded in the mid-seventeenth century was tenebrion (one that will not be seen by day, a lurker, a night-thief (also a “night-spirit” and “hobgoblin”)).  In Christianity, the Tenebrae is a religious service celebrated by the Western Church on the evening before or early morning of Maundy Thursday, Good Friday, and Holy Saturday, involving the gradual extinguishing of candles while a series of readings and psalms are chanted or recited.  In fine art, the related tenebrism describes a style of painting using very pronounced chiaroscuro, with darkness a dominating feature of the image and a tenebrist is an artist applying the method.  Works in the genre are said to be tenebristic and in the late nineteenth century those painting in this manner (described usually as “in the style of Caravaggio” were called the tenebrosi; by 1959 the preferred term among art historians was tenebrism.

The MOGAI

MOGAI stands for “Marginalized Orientations, Gender Alignments and Intersex” and is something of an omnibus term, acting as an umbrella term for sexual orientations, gender identities and intersex traits not considered “mainstream” although the very notion of “mainstream” is now a morass of cross-cutting claims, some factions demanding inclusion, others insisting on their separateness.  Whatever has been the track of MOGAI since its emergence in 2015, the original intent seems to have been one of “inclusiveness” and in that sense it’s both a logical extension of the LGBTQ+ concept and a recognition that so many categories could be identified the “extended model” (ie LGBTQQIAAOP and such) was becoming unmanageable.  Even “LGBTQ+” was in a sense counter-productive because in relegating certain letters (and thereby individuals or groups) to the “+”, there was an act of marginalization which, in the modern construct could be deemed a microaggression.  What advocates emphasize is that MOGAI exists for marginalized identities and it’s also as a kind of clearing house for novel or less recognized gender labels.  

DSM-5-TR (Text revision (2022) of DSM-5 (2013)).

In the narrow technical sense, MOGAI is a classification system but its focus on non-binary and other gender identities that are not cisgender seems to have acted to encourage the growth in the creation of categories and while some have “filled a gap”, there’s also clearly been linguistic adventurism in the same way some have been beyond imaginative in the coining of long German compound nouns and others have describe phobia despite there being no evidence of the particular fear ever having been defined as a clinical condition or even reported, a phenomenon the marvellously comprehensive Phobiapedia cheerfully acknowledges.  Whereas the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM) exists to codify mental health conditions including phobias, MOGAI is just one of many list of gender identities but one which commands interest simply on the basis of numbers: it has spawned literally hundreds of entries and while some are “variations on a theme”, the breadth is striking.

The DSM contains two obviously tenebricose conditions, Social Anxiety Disorder and Seasonal Affective Disorder (a mood disorder characterized by recurrent depressive episodes that occur at particular times of the year, usually in winter), tenebrous used of the former figuratively, of the latter literally.  In a decision which may have been an agenda item on one of the editorial committee's meeting, it was decided the acronym “SAD” would be applied to Seasonal Affective Disorder (presumably on the basis it described the sadness associated with dark, wintery conditions); Social Anxiety Disorder typically is abbreviated as SoAD and the differentiation makes sense because while sadness can be associated with SoAD, it's the prime dynamic of SAD.  Multiple uses of acronyms is of course common but within the one publication it could confuse for the editors made a wise choice.  First described in 1984, SAD was included in the revision to the third edition (DSM-III-R (1987)) as a “seasonal pattern”, a modifier applied to recurrent forms of mood disorders, rather than as an independent entity.  In the DSM-IV (1994), its status as a standalone condition was changed, no longer classified as a unique mood disorder but instead a specifier (called “with seasonal pattern”) for the “recurrent major depressive disorder that occurs at a specific time of the year and fully remits otherwise”.  In the DSM-5 (2013), although there were detail changes in terminology, the disorder was again identified as a type of depression (Major Depressive Disorder with Seasonal Pattern).  The symptoms of SAD often overlap with the behaviors & mood changes noted in clinical depression, the novelty being the condition manifesting usually during the fall (autumn) & winter when temperatures and lower and the hours of sunlight fewer, the symptoms tending to diminish with the onset of spring.

A gathering of high tech, robotic lawnmowers: Four Stihl iMows of the apocalypse.

Suggested collective nouns for lawnmowers have included “graze”, “scythe”, “lawn” & “swathe” but the most evocative was the (presumably Australian) “startyafuquer” (pronounced stahrt-yuh-fuhk-ah).  Most “high tech” lawnmowers are controlled using a cell phone app but some include the feature of a user being able to create their own voice-activation command set so “startyafuquer” could be recorded as the “start command”, the obvious companion phrase being “stopyafuquer”.

While notably less common, there are those who experience SAD during the summer and in either case it’s seen more frequently in women; SAD appears to be possible at any age but is most typically suffered in the age range 18-30.  In the US, the dynamic of the condition is illustrated by the diagnosis of SAD ranging from 1.4% of the population in sunny Florida to 9.9% in often gloomy Alaska and, after some initial scepticism, the condition was accepted as legitimate by most of the profession although there has been some contradictory research.  Although in a sense SAD has for centuries been documented in the works of poets and artists, it wasn’t until the mid-twentieth century that structured research began and it has been linked to a biochemical imbalance in the brain prompted by exposure to reduced hours of daylight and a reduction in sunlight.  It’s thought that as the seasons go by, some experience a shift in their internal “biological clock” (circadian rhythm) which induces the mechanism to become asynchronous with their daily schedule.  Predictably, SAD appears more prevalent among those living far from the equator where the conditions in winter are exaggerated.  Seemingly paradoxically, clinicians treating SAD do in some cases recommend “outdoor activities” on the basis (1) of “confronting the problem” as is sometimes done for fears (heights, spiders etc) and (2) its frequent effectiveness in countering depression.  One popular activity suggested is gardening and while many have reported it as therapeutic, those suffering from Sponeopapaaughprosebeeanthropopcacareophobia (the phobia describing the “fear of high tech lawn mowers”) would need to be cautious in their choice and handling of equipment.   

Gender lists are however not “peer reviewed” in the traditional sense (controversial as that model of academic publishing has become) so in a sense all the categorization systems are of equal validity with users free to determine which works best for them.  That’s democratic and how a classic marketplace of ideas operates but does mean it’s a field in which most are left to make of it what they will.  It would be interesting to compare a “comprehensive list” curated by academics in the now well-populated discipline of “gender studies” with the hundreds of entries which the MOGAI community hosts.  In the most recent edition of the DSM (DSM-5-TR, 2022), while there are five sub-types of specific phobias: (1) animals, (2) the natural environment, (3) blood, injections, medical procedures and such, (4) situational types (airplanes, elevators, enclosed spaces etc) and (5) other types, officially, terms like nomophobia, coulrophobia, globophobia, arachibutyrophobia etc) are no longer accepted clinical terms used in psychiatry and instances are grouped to be diagnosed as “Specific Phobia, other type”.  Remarkably, given the frequency of use of xxx-phobia in general use, only two explicitly are mentioned in the DSM and they are not unrelated: Agoraphobia (an extreme or irrational fear of entering open or crowded places or leaving one's home) and Social Anxiety Disorder (SoAD or Social anxiety).

The MOGAI community's lists of gender types are an invaluable resource but can be challenging for those suffering Albumistaphobia (the phobia describing the “fear of lists”).

Still, even if many of MOGAI’s entries might not survive an academic cull, there would be gender theorists or activists who might acknowledge the entire set because a syndrome need not be widespread to be defined as such: a single case can establish the diagnosis.  Word nerds too must have been impressed by the diversity and intricacy (if not always the grammar and spelling) because MOGAI definitions can also be mapped onto specific systems or sets of labels, such as the Celestial Gender System (based on celestial bodies) or the Restaurant System (based on restaurants and eateries).  What that has meant is that as well as serious contributions, the MOGAI community has seen the creation of new labels of dubious practical validity which, like some alleged phobias, clearly exist just because their creation was possible and fun.  Those schooled in labelling theory might also be interested because, once created and vested with the “validity” of appearing in a “gender list” on the internet, a label can gain some gravitational pull and convince readers they’ve just discovered their “true gender” identity or identities.  As patients can create the diagnosis, so the diagnosis can create the patient.

Xenogender

A xenogender identity is one in which a person's gender is connected to an aesthetic or sensory experience.  It is non-binary and applies concepts beyond traditional male, female or androgynous categories to describe a gender that cannot be contained by traditional human understandings of gender.  Xenogender claims to be all-encompassing and is this positioned as an umbrella term for identities related to abstract sources like animals, plants, concepts and imaginary or inanimate objects; the linkages need not in any way be literal or concrete and can be simply a device people use to best articulate how their gender “feels” (or “appears” for those who view themselves from beyond their own physical body) to them.  Some xenogenders are used by the neurodivergent community but the essence of xenogenderism is they cannot be exclusive and thus cannot be used in an exclusionary way.

Hallowgender

Hallowgender (or Halloweengender) is an aesthetigender in which one's gender is tied closely to “the silly part of Halloween and the Halloween aesthetic” (ie it focuses on the fun rather than the dark and scary).  The first known use of hallowgender was by Tumblr user asukazepplinsoryu in 2014.

TFS: The Tenebrous Gender System

A fork of the MOGAI community, the TGS (Tenebrous Gender System) was said to have been created by Tumblr user Hallowgender who on 12 September 2020 published a codified version; under TGS, all sub-types are in some way and to some degree connected to “darkness and gloominess”.  All are related also to other things or concepts and that some of those might stand in stark contradiction to darkness and gloominess was noted without further comment.  In a sign of the times, TGS, with seven categories, is said to be “one of the smallest gender systems” and that reflects the recent proliferation from something which for millennia usually was represented as a binary.  Each TGS category has a flag:

Tenebrariarumian: A gender that is dark, enveloping, and colorful.  It is gloomy, calming and cold.  Exemplar: Billie Eilish (b 2001).

Tenebrasian: A gender that is dark, separating, and sullen.  It is gloomy, tumultuous and warm.  Exemplar: Lindsay Lohan (b 1986).

Tenebellariumian: A gender that is flamboyant, dark, cool, and wintry. It is gloomy, calming, and freezing as well but may tend also to fluidity and can be similar to Burlesgender.  Exemplar: Kim Kardashian (b 1980).

Tenebrationisian: A gender that is masculine, toasty, calming, and similar to the sea at night.  It is gloomy, calming, and connected to anchors, boats, and summer.  Exemplar: Alexandria Ocasio-Cortez (AOC, b 1989).

Tenebricosumian: A gender that is cautious, wintry, dark and comforting.  It is small, fluid, and flux.  Exemplar: Bernie Sanders (b 1941).

Tenebricumian: A gender that is icy, soft, watery and comforting. It is large, fluid, and flux.  Exemplar: Sydney Sweeney (b 1997).

Tenebrosumian: A gender that is icy, soft, electric and powerful.  It is large, fluid and flux as well.  It can be connected to lights in a city at night, blankets and snowy afternoons.  Exemplar: Jessica Simpson (b 1980).

Aesthetigender

Aesthetigender was said to have been coined in 2014 by Tumblr user curiosityismysin and the original description read: “a gender experience that is derived from, or the embodiment of, an aesthetic”; from that came the mission creep which saw the term evolve from a “standalone gender” to being an entire sub-category of MOGAI genders to the point where it is one of the largest.  The nature of the beast is such that within the rubric of aesthetigender it’s an irrelevance to try to determine where one ends and another begins and the extent of proliferation anyway made overlap inevitable.  As might be imagined, a category in which the imperative is “a gender which in some ways relates to an aesthetic” is so broad that probably all MOGAI genders could be made to fit under the umbrella, including terms that aren't obviously “aesthetically linked” because just as “everything is text”, in a sense, “everything has an aesthetic”.  That has to be right because the root of aesthetigender ultimately can be traced back to a rejection of gender as a binary and the nonbinary activist movement really began as something aesthetic before a conceptual framework was built.  The MOGAI community now lists over 600 known aesthetigenders and while some (like many entries in the phobia lists) are variants, jocular coinings or exercises in novelty, such is the breadth, there must be something for just about everyone; some illustrative examples are:

Abandoe: a gender similar to that of an abandoned house; could be dead, genderless or of themes being empty and intimidating.

Adorbian: a xenic alignment to cuteness or cute things.

Aesthetigxrl: a girl or woman who is also aesthetifluid.  Your aesthetigenders act as an overlay, affecting pronouns and desired presentation.  If the aesthetic is heavily aligned with a different gender, your gender might be obscured until the aestheticgender changes. Comes under the genderfluid umbrella. (Gxrl can be substituted with your main gender (bxy, boy, girl, xen, enby ect).
