Penthouse

Penthouse (pronounced pent-hous)

(1) An apartment or dwelling on the roof of a building, usually set back from the outer walls.

(2) Any specially designed apartment on an upper floor, especially the top floor, of a building.

(3) A structure on a roof for housing elevator machinery, a water tank etc.

(4) Any roof-like shelter or overhanging part.

(5) In real tennis, a corridor having a slanted roof and projecting from three walls of the court.

(6) As mechanical penthouse, a floor, usually directly under a flat-roof, used to house mechanical plant & equipment.

(7) A special-interest magazine, aimed at a mostly male audience and published in several editions by a variety of owners between 1965-2023.

1520–1530: Despite the appearance penthouse is not a portmanteau (pent + house) word.  Penthouse is an alteration (by folk etymology) of the Middle English pentis, pentiz & pendize (and other spellings), from the Old French apentiz & apentis (appendage, attached building), the construct being apent (past participle of apendre (to hang against)) + -iz (the French -is ) from the unattested Vulgar Latin –ātīcium (noun use of neuter of the unattested –ātīcius, the construct being the Latin -āt(us) (past participle suffix) + -īcius (the adjectival suffix)).  Old French picked up apentis from the Medieval Latin appendicium (from the Classical Latin appendo (to hang) & appendere (to hang from).  A less common alternative variant to describe a shed with a sloping roof projecting from a wall or the side of a building was pentice.  Penthouse is a noun & verb, penthousing is a verb and penthoused & penthouslike are adjective; the noun plural is penthouses.  The adjectives penthouseish & penthousesque are non-standard.

Penthouse magazine, December 1993.

First published in 1965, Penthouse magazine was one of many ventures (in many fields) which proved unwilling or unable to adapt to the changes wrought by the internet and the atomization of the delivery of content; its last print edition (after a few stuttering years) appeared in 2023 although there must remain some perception of value in the name because of the decades-long prominence of the title and it's not impossible there will be a revival, even if it's unlikely to re-appear in the glossy magazine format of old.  In Australia, for students of the print industry the comparison between the “men’s magazines” Penthouse and Playboy (first published in 1953, on-line since 2020 and a print “annual edition” appeared in 2025) was something like that between the “women’s magazines” Cosmopolitan (since 1965 in its current niche) and Cleo (1972-2016) in that the two pairings were superficially similar but different in emphasis.  Not too much should be made of that because although identifiably there were “Cosmo women” & “Cleo women” (presumably with some overlap at the margins), between Penthouse and Playboy there were probably more similarities than variations.  Structuralists explained the difference between the two genres: “men’s magazines” were bought by men so they could look at pictures of women not wearing clothes while “women’s magazines” were bought by women so they could look at pictures of women wearing clothes.

When the lovely Ms Schiffer appeared on the cover of the December 1993 edition of Penthouse, the editors may not have been aware of the beast which was coming to consume them but it was in April 1993 CERN (in 1953 the Conseil Européen pour la Recherche Nucléaire (European Council for Nuclear Research) but the following year re-named Organisation européenne pour la recherche nucléaire (European Organization for Nuclear Research) with the acronym retained because it was both more mnemonic and pronounceable than OERN) released into the public domain details of technology which would allow the free development of applications using the www (world wide web) which ran atop the internet, making indexed content more easily accessible and distributable.  When in April 1993 the NCSA (National Center for Supercomputing Applications) released version 1.0 of its Mosaic web browser, it triggered a social and industrial revolution which (variously on TikTok, X (formerly known as Twitter), FoxNews and such) continues to unfold.  Mosaic wasn’t the first web browser but it was the first to gain a critical mass and the applications which superseded it claimed many victims including Penthouse magazine.

Iso, the Grifo and the Penthouse

1965 Iso Grifo Bizzarini A3/C, Le Mans, 1965.

One of the most admired of the trans-Atlantic hybrids of the post-war years (1945-1973) which combined elegant coachwork, (hopefully) high standards of craftsmanship and the effortless, low-cost power of large-displacement American V8 engines, the Iso Grifo was produced between 1965-1974 by the Italian manufacturer Iso Autoveicoli.  Styled by Bertone’s Giorgetto Giugiaro (b 1938) with engineering handled by the gifted Giotto Bizzarrini (1926-2023), the Grifo initially used a 327 cubic inch (5.3 litre) version of the small-block Chevrolet V8, coupled with the equally ubiquitous Borg-Warner (four & five speed) manual gearbox or robust General Motors (GM) Turbo-Hydramatic automatics.  Later, after some had been built with the big-block Chevrolet V8, GM began to insist on being paid up-front for hardware so Iso negotiated with the more accommodating Ford Motor Company (FoMoCo) and switched to 351 cubic inch (5.8 litre) versions of their 335 (Cleveland) engine.

1955 Iso Isetta.

Iso was already familiar with the mechanical configuration, production of their Rivolta coupe, equipped also with the Chevrolet 327, having begun in 1962.  The Rivolta, let alone the Grifo was quite a change of direction for Iso which until then had produced a variety of appliances, scooters & moto-cycles, it’s most famous product the Isetta, one of the generation of “bubble cars” which played such a part in putting Europeans back on (three or four) wheels during the re-construction of the early post-war years.  Surprisingly, despite the prominence of the Isetta name and the Italian association, barely a thousand were actually manufactured by Iso, the overwhelming majority produced in many countries by BMW and others to which a license was granted.  The bubble cars were a product of the economic circumstances of post-war Europe and the ones produced in England even used the single rear wheel which had been abandoned by Iso because of the inherent instability; UK taxation laws made three-wheelers significantly cheaper and only a motor-cycle license was required to drive one.  Powered by tiny two and four-stroke engines, their popularity waned as “real” cars such as the Fiat 500 (1955-1975) and later the BMC (British Motor Corporation) Mini (1959-2000) emerged; although costing little more than the bubble cars, they offered more space, performance and practicality.  By the early 1960s, the bubble cars were almost extinct but, as a tiny specialized niche, they never completely vanished and the Isetta is enjoying a twenty-first century revival as model urban transportation, including the option of (Greta Thunberg (b 2003) approved) electric propulsion.  Once dismissed as dated and even absurd, their bug-eyed look is now thought to have "retro-charm".

1968 Iso Rivolta.

The Rivolta was thus quite a jump up-market and, while the engine wasn't the bespoke thoroughbred found in a Ferrari or Aston-Martin, the rest of the specification justified the high price.  Unlike some of the British interpretations using American V8s, Iso insisted on modernity, the platform probably the best of the era with a body welded to a pressed-steel chassis, a combination which proved both light and stiff.  Just as importantly, given the high rate of corporate failure among those attracted to this potentially lucrative market, it was cost-effective to manufacture, reliable and easy to service.  Probably the feature which let it rank with the most accomplished of the era was the sophisticated de Dion rear suspension which, combined with four wheel disc brakes, lent it a rare competence (surprising some Maserati and Ferrari drivers, their cars with rear suspension designs dating from the horse & buggy era).  The de Dion design was not an independent arrangement but certainly behaved as if it was and, despite what Mercedes-Benz claimed of their beloved swing-axles, was superior to many of the independent setups on offer.  A noted benefit of the de Dion system is it ensures the rear wheels remain always parallel, quite an important feature in an axle which has to transmit to the road the high torque output of a big V8, a lesson Swiss constructor Peter Monteverdi (1934–1998) applied later in the decade when he went into production using even bigger engines.  Iso, with a solid base in accounting and production-line economics, ran an efficient and profitable operation not beset by the recurrent financial crises which afflicted so many and the elegant Rivolta was a success, remaining available until 1970.  Some eight hundred were sold.

1967 Iso Grifo Series One.

The Rivolta’s platform proved adaptable.  In 1965, Iso released the Grifo coupé which was more overtly oriented to outright performance and strictly a two-seater.  With lovely lines and a modified version of the Rivolta’s fine chassis, the Grifo was another product of the fertile imaginations of Giugiaro & Bizzarrini but, in something not untypical in Italian industry of the time, the relationship between the latter and Iso’s founder Renzo Rivolta (1908–1966) soon became strained and was sundered.  Bizzarrini would go on to do remarkable things and Iso’s engineers assumed complete control of the Grifo after the first few dozen had been completed.  Bizzarrini had pursued a twin-stream development, a competition version called the A3/C with a lower, lightweight aluminum body as well as the road-going A3/L and when he decamped, he took with him the A3/C, to be released also under his name while Iso devoted its attentions to the A3/L, again using engine-transmission combinations borrowed from the Chevrolet Corvette.

1964 Iso Grifo A3/L Spider prototype by Bertone.

The Grifo weighed a relatively svelte 1430 kg (3153 lbs) in what must have been a reasonably slippery shape because the reports at the time confirmed some 240 km/h (150 mph) was easily attained, an increase on that managed by the C2 Corvette (1962-1967 and which turned out to be not aerodynamically efficient as it looked) and, when configured with the taller gearing the factory offered, the factory claimed 260 km/h (162 mph), was possible.  A test in the UK in 1966 almost matched that with a verified 161 mph (259 km/h) recorded and two years later, the US publication Car & Driver 1968 tested a 327 Grifo but didn't to a top-speed run, instead estimating 157 mph (253 km/h) should be possible given enough road.  There were surprisingly few variations, fewer than two-dozen made with a targa-style removable roof panel and a single, achingly lovely roadster was displayed on Bertone's stand at the 1964 Geneva Motor Show; it remained a one-off although a couple of coupés privately have been converted.  What made the Bertone prototype special however was it was a companion to the original A3/L prototype coupé with which it shared a number of distinctive features including (1) a side exhaust rakishly snaking through the passenger side of the cowl and under the rocker panel trim with its an almost matte finish, (2) frontal styling with the then fashionable “twin-nostril” fascia and (3) angled vents in the rear fenders.  Although visually similar to the series production Grifos, almost every line on the pair of A3/L prototypes was in some subtle way different.

Although well-known in the collector community for its large stocks of rusty and wrecked Porsches, Mercedes-Benz and other notable vehicles from the post-war years, the Californian “junkyard” belonging to Rudi Klein (1936-2001) attracted world-wide interest when details were published of the gems which had for decades been secreted in the site's large and secure shed.  Mr Klein was a German butcher who in the late 1950s emigrated to the US to work at his trade but quickly discovered a more enjoyable and lucrative living could be had dealing in damaged or wrecked European cars, sometimes selling the whole vehicles and sometimes the parts (“parting out” in junkyard parlance).  His Porsche Foreign Auto business had operated for some time before he received a C&D (cease & desist) letter from the German manufacturer’s US attorneys, the result being the name change in 1967 to Porche (sic) Foreign Auto.  Unlike many collectors, Mr Klein amassed his collection unobtrusively and, astonishingly to many, apparently with little interest in turning a profit on the rarest, despite some of them coming to be worth millions.  After Mr Klein died in 2001, his two sons preserved the collection untouched until, in October 2024,the auction house Sotheby’s began a series of rolling sales, one to go under the hammer the one-off Grifo spider.  At some point there was an accident which damaged the nose so a standard Grifo facia was installed and in this form Mr Klein ran it for a while as a road car before parking it in the shed among its illustrious companions.  Remarkably original except for the nose, it sold for US$1,875,000 and the expectation is it will be fully restored (including a fabricated replica of the original nose) before appearing on the show circuit.  In the decades to come, it will likely spend its time in collections with the occasional outings to auction houses.

1970 Iso Grifo Targa (left) Series Two and 1971 Iso Grifo Can-Am (454) Targa.  Only four Series II Can-Ams were built with the targa roof.

The bodywork was revised in 1970, subsequent cars listed as Series Two models.  The revisions included detail changes to the interior, improvements to the increasingly popular air-conditioning system and some alterations to the body structure, the hydraulics and electrical system, some necessitated by new regulatory requirements in Europe but required mostly in an attempt to remain compliant with the more onerous US legislation.  The most obvious change was to the nose, the headlamps now partially concealed by flaps which raised automatically when the lights were activated.  Presumably the smoother nose delivered improved aerodynamics but the factory made no specific claims, either about performance or the drag co-efficient (CD) number.

1972 Iso Lele & 1972 Iso Fidia.

In 1972, an unexpected change in the power-train was announced.  After almost a decade exclusively using Chevrolet engines, Iso issued a press release confirming that henceforth, the Series Two Grifo would be powered by Ford’s Boss 351 cubic inch (5.8 litre) 335 series (Cleveland) V8.  In the state of tune (close to that fellow Italian specialist De Tomaso were using in their mid-engined Pantera) chosen, the Ford engine was similar in size, weight to the small-block Chevrolet and delivered similar power and torque characteristics so the driving experience differed little although there were 22 high-performance Leles using a tuned 351, all with a ZF five-speed manual gearbox.  The other improvement in performance was presumably Iso’s balance sheet.  The switch had been made because internal policy changes at GM meant they were now insisting on being paid up-front for their product whereas Ford was still prepared to mail an invoice with a payment term.  The change extended to the other models in the range, the Lele coupé and Fidia saloon and while the Chevrolet/Ford split in the Lele was 125/157, the circumstances of the time meant that of the 192 Fidias made, only 35 were fitted with the 351.

1969 Iso Grifo 7 Litre (427).

One of the trends which made machines of the 1960s so memorable was a tendency never to do in moderation what could be done in excess.  In 1968, Iso announced the Grifo 7 Litre, built following the example of the US manufacturers who had with little more than a pencil and the back of an envelope worked out the economics of simple seven litre engines were more compelling than adding expensive components like overhead camshafts and fuel-injection to five litre engines; in the US, gas (petrol) was then relatively cheap and and assumed by most to be limitless.  Gas wasn’t as cheap in Italy or the rest of Europe but Iso’s target market for the Grifo was those who either could afford the running costs or (increasingly) paid their bills with OPM (other people’s money) so in those circles fuel consumption wasn’t something often considered or much discussed.  The new version used a 427 cubic inch (7.0 litre) version of the big-block Chevrolet V8, bigger and heavier than the 327 so the driving characteristics of the nose-heavy machine were changed but contemporary reports praised the competence of the chassis, the de Dion rear-end notably superior in behavior compared with the Corvette’s independent rear suspension although some did note it took skill (which meant often using some restraint) effectively to use the prodigious power.  Tellingly, the most receptive market for the Grifos, small and big-block, was the  FRG (Bundesrepublik Deutschland (Federal Republic of Germany; the old West Germany) 1949-1990) with its network of highways without the tiresome speed limits elsewhere imposed and (even in Italy), often enforced.  The Autobahn really was the Grifo's native environment.

1971 Iso Grifo Can Am (454).

Faster it certainly was although the factory’s claim of a top speed of 186 mph (a convenient 300 km/h) did seem optimistic to anyone with a slide-rule and there appears not to be any record of anyone verifying the number although one published test did claim to have seen well over 255 km/h (150 mph) with the Grifo still "strongly accelerating" before “running out of road”.  It had by then become a genuine problem.  Gone were the happy times when testers still did their work on public roads; increased traffic volumes by the late 1960s meant the often deserted stretches of highway (in 1956 an English journalist had taken a Mercedes-Benz 300SLR Coupé to 183 mph (294 km/h) on the autobahn) were now rare but whatever the terminal velocity, nobody seemed to suggest the 7 litre Grifo lacked power.  In 1970, after Iso’s stock of the by-then out-of-production triple carburetor 427 were exhausted, the big-block car was re-named Can-Am and equipped instead with a 454 cubic inch (7.5 litre) version, the name an allusion to the unlimited displacement Group 7 sports car racing series run in North America in which the big-block Chevrolets were long the dominant engine.

Despite the increased displacement, power actually dropped a little because the 454 was detuned a little to meet the then still modest anti-emission regulations.  Officially, the 454 was rated at 395 HP (gross horsepower) but the numbers in that era were often at best indicative: The Boss 429 Mustang was said to produce 375 HP whereas the 500 cubic inch (8.2 litre) V8 in the FWD! (front-wheel-drive) Cadillac Eldorado was rated at 400; a comparison of their performance belies the numbers and the difference is not all accounted for by the Eldorado's weight and power-sapping accessories.  As early as the the mid-1960s Detroit had begun understating the output of many of their high-performance engines and as politicians and insurance companies (for their own reasons) became interested, the trend continued.    

1971 Iso Grifo Can Am (454).

Unlike the 427 which breathed through three two barrel carburetors, the 454 was equipped with less intricate induction, a single four barrel and while with output (officially) dropping from 435 to 395 HP, performance was s little blunted although it's probable few owners often went fast enough to tell the difference.  What didn’t change between the 7 Litre and the Can Am was its most distinctive feature, the modification to the hood (bonnet) made to ensure the additional height of the 427's induction system could be accommodated.  The raised central section, the factory dubbed "the penthouse".

Penthouse on 1969 Iso Grifo 7 Litre (427).

Not everyone admired the stark simplicity, supposing, not unreasonably, Giugiaro might have done something more in sympathy with its surroundingsCritics more stern would have preferred a curvaceous scoop, blister or bulge and thought the penthouse amateurish, an angular discordance bolted unhappily atop Giugiaro’s flowing lines  but for those brought up in the tradition of brutalist functionalism, it seemed an admirable tribute to what lay beneath.  The days of the big-block Grifo were however numbered.  In 1972, with Chevrolet no longer willing to extent credit and Ford’s big-block (429 & 460) engines re-tuned as low-emission (for the time) units suitable for pickup trucks and luxury cars, the Can-Am was retired.  So the small-block 351 Grifo became the sole model in the range but it too fell victim to changing times, production lasting not long beyond the first oil shock (triggered by the OAPEC (Organization of Arab Petroleum Exporting Countries) on 17 October 1973 imposing an embargo on crude oil exports to certain countries) which made gas suddenly not only much more expensive but sometimes also scarce and the whole ecosystem of the thirsty trans-Atlantic hybrids became threatened; in little more than a year, Iso was one of the many dinosaurs driven extinct.  Decades later, the survivors of the 414 sold are highly desirable; fine examples of the small-block Grifos attract over US$500,000, the few dozen penthouse have sold for close to a million and the rare early A3/Cs for even more.

From the lost, tactile days of buttons and toggle switches: 1966 Iso Grifo, one of 31 built in RHD (right hand drive).

Not fans of brutalist functionalism were the Lancia-loving types at Road & Track (R&T) magazine in the US.  Late in 1974, R&T published their 1975 buyer’s guide for imported and domestically-built smaller cars (R&T neither approving of nor understanding why anyone would wish to buy a big American car) and surprisingly, there were reviews of the Grifo, Lele and Fidia although the last of these sold in the US some two years earlier had been titled as 1973 models, the company having never sought to certification to continue sales although, given nothing had been done to modify them to meet the new safety regulations, that would likely have been pointless unless the strategy was to seek a "low volume" exemption, something improbable by 1975.

A tale of two penthouses: Paradoxically, as installed in the Grifo the induction system of the big-block Chevrolet V8 sat a little lower than that of the small-block Ford (a not unusual anomaly in the small-block vs big-block world) so the Ford-engined Grifos (right) used a taller penthouse than those fitted with the Chevrolet unit.     

The distributors had however indicated to the press all three would return to the US market in 1975, supplying publicity photographs which included a Series II "penthouse" Grifo.  A further complication was that during 1974, Ford had discontinued in the US production of the high-performance 351 (the "Cleveland" 335 series which was exiled to Australia) V8 so it wasn't clear what power-train would have been used.  Others had the same problem, De Tomaso (which withdrew from the US market in 1974) switching to use tuned versions of the Australian-built 351s but for Iso, the whole issue became irrelevant as the factory was closed late in 1974.  R&T's last thoughts on the penthouse appeared in the buyer's guide: "However, the clean lines of the original Grifo have been spoiled by that terrible looking outgrowth on the hood used for air cleaner clearance.  For US$28,500 (around US$155,000 in 2025 US$ although direct translation of value is difficult to calculate because of the influence of exchange rates and other variables), a better solution to this problem should have been found."

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).
