Parsec

Parsec (pronounced pahr-sek)

A unit of astronomical length, based on the distance from Earth at which a star would have a parallax of one second of arc which is equivalent to 206,265 times the distance from the earth to the sun or 3.26 light-years.  Its lineal equivalent is about 19.1 trillion miles (30.8 trillion km).

1913: The construct was par + sec, derived from parallax + second.  Parallax is from the Middle French parallaxe, from the Ancient Greek παράλλαξις (parállaxis) (alteration) from παραλλάσσω (parallássō) (to cause to alternate) from λλάσσω (allássō) (to alter) from λλος (állos) (other).  Second, in the sense of time, is from the Middle English secunde & seconde, borrowed from the Old French seconde, from the Medieval Latin secunda, short for secunda pars minuta (second diminished part (of the hour)). Parsec is a noun; the noun plural is parsecs.

Distance in space

The parsec (pc) is a unit of length used to measure large distances to astronomical objects outside the Solar System.  A parsec is defined as the distance at which one astronomical unit subtends an angle of one arc second, which corresponds to 648000 astronomical units.  The nearest star to Earth, Proxima Centauri, is about 1.3 parsecs (4.2 light-years) from the Sun.

The parsec unit appears first to have been suggested in 1913 by the English astronomer Professor Herbert Hall Turner (1861-1930).  It was invented to permit calculations of astronomical distances using only raw observational data and is thus the default unit of measure in astronomy and astrophysics although the more-easily understood light-year is preferred by lay-persons.  While useful to describe the comparatively short distances within the Milky Way, multiples of parsecs are needed to map the wider universe including kiloparsecs (kpc) for objects immediately beyond the Milky Way and megaparsecs (Mpc) for more distant galaxies.  Gigaparsecs (Gpc) are used to measure the quasars and galaxies which exist at the extreme edge of the known universe; the particle horizon (the boundary of the observable universe) has a radius of about 14.0 Gpc (46 billion light-years).

Although in use for more than a century, the parsec wasn’t formally defined until August 2015 when the International Astronomical Union (IAU) which, as part of the definition of a standardized absolute and apparent bolometric magnitude scale, noted the existing explicit definition of the parsec as exactly 648000 astronomical units, or approximately 3.08567758149137×1016 metres.

Stratosphere

Stratosphere (pronounced strat-uh-sfeer)

(1) The region of the upper atmosphere extending between the tropopause and mesosphere to about 30 miles (50 kilometers) above the earth, characterized by little vertical change in temperature.

(2) In historic documents, all of the earth's atmosphere lying outside the troposphere (obsolete).

(3) Any great height or degree of anything, as the highest point of a graded scale.

(4) In geology, collectively, those layers of the Earth’s crust which primarily comprise stratified deposits (obsolete).

1908: From the French stratosphère, the construct being strato + sphère (literally "sphere of layers").  It was coined by French meteorologist Léon-Philippe Teisserenc de Bort (1855-1913).  Strato was an inflected form of strātus (a spreading out), the perfect passive participle of sternō (spread) and past participle stem of sternere (to spread out) from the primitive Indo-European root stere- (to spread).  Sphere was from the Middle English spere, from the Old French sphere, from the Medieval Latin sphēra, from the Classical Latin sphaera (ball, globe, celestial sphere), from the Ancient Greek σφαρα (sphaîra) (ball, globe) of unknown origin and despite the apparent similarity, not related to the Persian سپهر‎ (sepehr) (sky).  The earlier use of the word, attested in English 1908 and coined in German 1901, was a geological term for part of the Earth's crust and has long been wholly obsolete.  The second major layer of Earth's atmosphere, the stratosphere sits above the troposphere and below the mesosphere.  Itself stratified, the stratosphere’s cooler layers are closest to the Earth’s surface, the higher layers warmed by the absorption of the Sun's ultraviolet radiation in the ozone layer, a reversal of the process in the troposphere where temperature decreases with altitude.  Stratosphere is a noun, and stratospheric & stratospherical are adjectives; the noun plural is stratospheres.

Layers

It was once thought the first living things to enter the stratosphere were some fruit flies, sent there by the US Air Force aboard one of the V-2 rockets seized from the German's wartime missile programme.  Launched in February 1947 from the White Sands Missile Range in New Mexico, the purpose of the flight was to explore the effects of radiation exposure at these then novel high altitudes; the V2 attained a height of 68 miles (109 kilometres) and all fruit flies survived the trip.  It was soon appreciated however that some bacteria or viruses must have been present in or on the V2s launched by the Germans between 1944-1945 and many of these would, at least briefly, have entered the stratosphere but even these appear not to have been the first living (and viruses are in some sense “alive”) things there.

Although the tropopause (the uppermost layer of the troposphere) is thought a barrier to the upward movement of particles, volcanoes are an obvious means by which this could occur although such eruptions are rare.  Bacterial life does however survive in the stratosphere, making it technically, part of the biosphere and, in 2001, dust was collected at a height of 25 miles (41 kilometres) which, upon analysis, was found to contain bacteria of surprisingly large size.  The discovery excited speculation that such large bacterial masses may be incoming to Earth, the suggestion being that (1) the bacteria may have arrived in the stratosphere from space and (2) the possibility that the transfer of bacteria from the Earth to the highly mutagenic stratosphere may have played a role in bacterial evolution.  Among the scientific community, enthusiasm for these theories was restrained.

Lambeth

Lambeth (pronounced lam-bith)

(1) A south London suburb, the location of Lambeth Palace, the seat of the Archbishop of Canterbury.

(2) A slang term for the hierarchy of the Church of England.

The name Lambeth embodies hithe, a Middle English word for a landing on the river.  Lambeth Palace has for some eight-hundred years been the official London residence of the Archbishop of Canterbury.  It sits on the south bank of the Thames, a quarter mile (400m) south-east of the Palace of Westminster, which contains the houses of parliament, on the opposite bank.

Rowan Williams (b 1950; Archbishop of Canterbury 2002-2012) and Benedict XVI (1927–2022; pope 2005-2013, pope emeritus 2013-2022) chat at Lambeth Palace.

The Lambeth Conference

The Lambeth Conference is a (nominally) decennial assembly of bishops of the Anglican Communion convened by the Archbishop of Canterbury.  There have been fourteen Lambeth Conferences, the first in 1867.  The Anglican Communion is an international association of autonomous national and regional churches, not a governing body and the office of Archbishop of Canterbury is in no way analogous with the Roman Catholic Pope.  The conferences serve a collaborative and consultative function and are said to express “…the mind of the communion" on issues of the day. Resolutions passed at a Lambeth Conference are without legal effect, but can be influential.

Conferences were never the pure and high-minded discussions of ethics, morality and theology some now appear to believe characterized the pre-modern (in this context those held prior to 1968) events.  Agenda and communiqués from all conferences have always included the procedural, administrative and jurisdictional although in recent years, they’ve certainly reflected an increasingly factionalized communion rent with cross-cutting cleavages, first over the ordination of women and of late, homosexual clergy.  During the 1998 conference, Bishop Chukwuma (b 1954) of Nigeria attempted to exorcise "homosexual demons" from the soul of Nigerian-born Richard Kirker (b 1951), a British priest and general secretary of the Lesbian and Gay Christian Movement.  Recalling probably Ephesians 4:32 or perhaps the more cautionary Matthew 6:15, Kirker forgave him.

The spirit of Kirker notwithstanding, at this point, the disagreements seem insoluble.  The poisonous atmosphere at, and in the aftermath of, the last conference in 2008 did not enhance the image of the church and a typically Anglican solution to avoid a repetition in 2018 seemed to have emerged.  In 2014, in answer to the suggestion he had cancelled the 2018 conference, Archbishop Justin Welby (b 1956; 105th Archbishop of Canterbury 2013-), in a statement worthy of any of his predecessors, responded by stating, "As it hasn’t been called, it can’t have been cancelled."

A communiqué issued after the primates' meeting in January 2016, noted the bishops had accepted the archbishop’s proposal the fifteenth conference should be held in 2020.  However, because of the COVID-19 pandemic, it was in March 2020 decided to postpone the conference to the summer of 2021 but the virus proved elusive and by July, the delay had been extended to 2022.  The first epistle of Peter has been chosen as the biblical focus for the conference, the theme of which is said to be what it means to be “God’s Church for God’s World”.  The apostle Peter wrote this epistle to give comfort to Christians suffering persecution from non-believers, hoping to encourage them to live pure lives despite their vicissitudes.

Peter didn’t sugar-coat the message (1 Peter 4:12-19), making it clear that for Christians, suffering is actually a participation in the sufferings of Christ and is an occasion for rejoicing, helpfully adding that in the midst of the suffering, the Holy Spirit rests upon those who are suffering, this being a great consolation.  He further explains that God uses suffering to purify the Christian community, God's household.  God uses the abuse that pagans unjustly heap on Christians to prepare his people for the return of Christ and warns people not to be surprised at the fiery ordeal that will come upon them as followers of Jesus.  Actually, they should be both grateful and happy and thus glorify God, for if they share in Christ’s sufferings it means they will also share in his glory.

In a world beset by fire, flood, pestilence and plague, 1 Peter seems a good theme to loom over a Lambeth Conference.  Whether or not Christians beyond the Kent conference rooms will long note the message, it probably will resonate with Archbishop Welby’s predecessor, Rowan Williams (Baron Williams of Oystermouth, b 1950; 104th Archbishop of Canterbury, 2002-2012).  During his tenure at Lambeth, Dr Williams probably felt more ignored than persecuted by non-believers, finding the internecine squabbles of the believers in the Anglican factions rather more tiresome.  Declaring the problems in the church “insoluble” he seemed not unhappy to be leaving Lambeth to return to his study and write about Dostoevsky.  A generous spirit, he will have wished his successor well.

Cabotage

Cabotage (pronounced kab-uh-tij or kab-uh-tahzh)

(1) In seafaring, navigation or trade along the coast.

(2) In aviation, the legal restriction to domestic carriers of air transport between points within a country's borders (with certain exceptions).

(3) The transport of goods or passengers between two points in the same country; the exclusive right of a country to control such transport.

(4) In law, the right to engage in such transport.

1825–1835: A borrowing from the French cabotage (coasting trade) from the French caboter (to sail coastwise; to travel by the coast), a verbal derivative of the Middle French cabo & the Spanish cabo (headland; cape).  Ultimate root is the Latin caput (head).  Word was first used in sixteenth century France to reference the restrictions which permitted only French ships to trade or transport between French ports. Other countries adopted the concept, later extending it to land and air travel.  Cabotage is a noun; the noun plural is cabotages.

Rights

Example of a cabotage arrangement.

Originally a term applied exclusively to shipping along coastal routes, cabotage can now refer also to aviation and land transport.  It is the transport of passengers and/or goods between two places in one country, undertaken by vessels from a different country.  Cabotage rights are those which define the extent to which transport operators from one country can trade in another and many arrangements exist.  In aviation, it is the right to operate within the domestic borders of another country; most states don’t permit aviation cabotage, and strict sanctions exist, historically either for reasons of economic protectionism, national security, or public safety.  One exception is the European Union, the member states of which grant cross-vested rights to all others, cabotage rights remaining otherwise rare in passenger aviation.  The Chicago Convention on Civil Aviation prohibits member states from granting cabotage on an exclusive basis, which has meant it’s not been used in bilateral aviation negotiations and is not granted under most open skies agreements.  The Closer Economic Relations agreement between Australia and New Zealand permits Australian carriers to fly domestically and internationally from New Zealand and vice versa. Additionally, there are limited rights for the airlines to service domestic routes within both countries.

Hangry

Hangry (pronounced hang-gree)

Feeling irritable or irrationally angry because of hunger.

1915-1920: A portmanteau word, the construct being from h(ungry) + angry.  Hungry is from the Middle English hungry, from the Old English hungriġ & hungreġ (hungry; famishing; meager), from the Proto-Germanic hungragaz (hungry).  It was cognate with the Dutch hongerig, the German hungrig and the Swedish hungrig, all of which meant “hungry”.  Anger is from the Old Norse angr (affliction, sorrow).

Hungry (pre 950) was from the Middle English hungry & hungri, from the Old English hungriġ & hungreġ (hungry; famishing; meager) which existed also in the Common West Germanic and was from the Proto-Germanic hungragaz (hungry).  It was cognate with the German hungrig, the Old Frisian hungerig, the Dutch hongerig, the German hungrig and the Swedish hungrig, all of which meant “hungry”.  The use as a figurative form is noted from circa 1200.

Angry (1350-1400) in the sense of "hot-tempered, irascible; incensed, openly wrathful" is a construct of the earlier noun anger + -y,  The Old Norse adjective was ongrfullr (sorrowful) (the Old Norse angr meant “affliction, sorrow”), from the mid thirteenth century a Middle English form was angerful (anxious, eager).  The “angry young man” dates from 1941 but became a popular form only after John Osborne's (1929-1994) play Look Back in Anger was performed in 1956 although the exact phrase does appears nowhere in the text.  The rare related form is angriness.

The –y suffix is from the Middle English –y & -i, from the Old English - (-y, -ic), from the Proto-Germanic -īgaz (-y, -ic), from the primitive Indo-European -kos, -ikos, & -ios (-y, -ic).  It was cognate with the Scots -ie (-y), the West Frisian -ich (-y), the Dutch -ig (-y), the Low German -ig (-y), the German -ig (-y), the Swedish -ig (-y), the Latin -icus (-y, -ic) and the Ancient Greek -ικός (-ikós); a doublet of -ic.  The –y suffix was added to (1) nouns and adjectives to form adjectives meaning “having the quality of” and (2) verbs to form adjectives meaning "inclined to".

The cats Hillary & Bill: a question understandably frequent in some marriages.

Etymologists list hangry as a humorous invention in US English dating from circa 1915-1920 but use soon died out, not to be revived until 1956 when it was mentioned in the US psychoanalytic journal American Imago in a discussion about various kinds of deliberate and accidental wordplay.  Hangry, unlike some of contractions or elisions documented, survived (or was again revived) in the internet age, becoming popular from the mid-1990s and achieved sufficient linguistic critical-mass for the Oxford English Dictionary (OED) to accept it as a word in their 2018 update.  Even among those who dismiss hangry as slang, the usual rules of English should apply so the comparative is more hangry, the superlative most hangry, and the adjectives hangrier and hangriest.

Hangriness can lead to "diva-like behavior".  The Australian New Idea is a "women's magazine" offered still in a print edition as well as on-line.  Locally, the slang for the publication is "The No Idea".

Some dictionaries still resist, apparently not convinced it’s yet a proper word despite the usually authoritative imprimatur of the OED.  For those who side with the OED, of note is that hangry thus becomes only the third word in English to end in –gry, the other two being, predictably, angry and hungry.  There is the odd instance in the historic record of puggry (a light scarf wound around a hat or helmet to protect the head from the sun) but etymologists overwhelmingly say this is a mistake, a Raj-era corruption of the correct puggaree, from the Hindi, Urdu and Punjabi pagī (turban), related to the Punjabi pagg (turban) and Kashmiri pag (turban), all of unknown origin.  Angry, hungry & hangry are the only words in English ending in "gry".

Bacchanal

Bacchanal pronounced (bah-kuh-nahl, bak-uh-nal, bak-uh-nl (noun) or bak-uh-nl (adjective))

(1) A follower of Bacchus.

(2) A drunken reveler.

(3) An occasion of drunken revelry; orgy; riotous celebration.

(4) Of or pertaining to Bacchus; bacchanalian.

1530-1540: From the Latin Bacchānālis (having to do with Bacchus) & Bacchānālia (feast of Bacchus), plural of Bacchānal (a place devoted to Bacchus), from Bacchus (the god of wine), from the Ancient Greek Βάκχος (Bákkhos).  By extension, the meaning "riotous, drunken roistering or orgy" dates from 1711.  Bacchus, known also as Dionysus (Διόνυσος) (Dionysos) was in Greek Mythology the god of the grape harvest, winemaking and wine, of ritual madness, fertility, theatre and religious ecstasy.  In Antiquity, most attention focused on wine and given consumption was both high and enthusiastic, the worship of Bacchus became firmly established.  A quirk of Bacchus’ place in the pantheon of gods is that, uniquely, he was born of a mortal mother.  The Romans adopted the name bacchanal (a woman given to such things was a bacchante) and named the behavior of those who had taken too much strong drink: bakkheia.  Bacchanal is a noun & adjective, Bacchanalia is a noun; the noun plural is bacchanals.

Bacchus and Ariadne

Bacchus and Ariadne (1717) by Giovanni Antonio Pellegrini (1675-1741).

In Greek mythology, Ariadne was the clever, though perhaps naïve, daughter of King Minos of Crete and she aided the hero Theseus in his mission to slay the Minotaur.  To say naïve might be understating things: poor sweet Ariadne was an emo and a bit of a dill.  On the island of Crete, there was a great labyrinth that housed a fearsome beast, the Minotaur, half human, half bull.  King Minos, in retaliation for his son's death at the hands of an Athenian, required the people of Athens every nine years to send seven young men and seven young virgins to be sacrificed to the beast, the alternative the destruction of their city.  One year, Theseus volunteered to be sent to Crete as part of the awful pact, planning to kill the Minotaur and thereby release his people from their plight.  When he stepped ashore in Crete, Ariadne spotted him and at once fell in love, as emos often do; running to Theseus, she offered to help him defeat the monster if he would marry her.  Theseus naturally agreed so Ariadne gave him a sword and a ball of red thread with which to mark his path so he could find his way out of the labyrinth.  The plan worked to the extent that Theseus slayed the Minotaur but certainly had no intention of marrying Ariadne.  While the couple traveled to Athens, during a brief stop on the island of Naxos, he sailed away, abandoning her while she slumbered on the beach.  Ariadne may have been an emo but Theseus was a cad.  Distraught by being deserted by the one she loved, Ariadne was still sobbing on the shore Bacchus appeared with a procession of his followers.  They spoke a few words and within moments had fallen in love, soon to marry.  In some tellings of the myths, after their wedding, Bacchus placed Ariadne's sparkling diadem in the sky as the constellation Corona, thus making her immortal.

Inflammable & Flammable

Inflammable (pronounced in-flam-uh-buhl)

(1) Easily set on fire; combustible; incendiary, combustible, inflammable, burnable, ignitable (recommended only for figurative use).

(2) Easily aroused or excited, as to passion or anger; irascible; fiery; volatile, choleric.

1595–1605: From the Medieval Latin inflammābilis, the construct being the Classical Latin inflammā(re) (to set on fire) + -bilis (from the Proto-Italic -ðlis, from the primitive Indo-European i-stem form -dhli- of -dhlom (instrumental suffix).  Akin to –bulum, the suffix -bilis is added to a verb to form an adjectival noun of relationship to that verb (indicating a capacity or worth of being acted upon).  Construct of the Classical Latin inflammare (to set on fire) is -in (in, on) + flamma (flame).

Flammable (pronounced flam-uh-buhl)

Easily set on fire; combustible; incendiary, combustible, inflammable, burnable, ignitable

1805–1815: From the Classical Latin flammā(re) (to set on fire) + -ble (the Latin suffix forming adjectives and means “capable or worthy of”).

Need for standardization

Flammable and inflammable mean the same thing.  English, a mongrel vacuum-cleaner of a language, has many anomalies born of the haphazard adoption of words from other tongues but the interchangeability of flammable and inflammable is unfortunate because of the use in signs to warn people of potentially fatal danger.

In- is often used as a prefix with adjectives and nouns to indicate the opposite of the word it precedes (eg inaction, indecisive, inexpensive etc).  Given that, it’s reasonable to assume inflammable is the opposite of flammable and that objects and substances should be so-labeled.  The reason for the potentially deadly duplication is historic.  Inflammable actually pre-dates flammable, the word derived from the Latin verb inflammare (to set on fire), this verb also the origin of the modern meaning “to swell or to provoke angry feelings”, hence the link between setting something on fire and rousing strong feelings in someone.  So, at a time when Latin was more influential, inflammable made sense.  However, as the pull of Latin receded, words with in- (as a negative prefix) became a bigger part of the lexicon and the confusion was created.  By the early nineteenth century, flammable had become common usage, and by the twentieth was widespread.  The modern convention is to use flammable literally (to refer to things which catch fire) and inflammable figuratively (to describe the arousal of passions, the swelling of tissue etc.  Surprisingly, the rules applying to warning signs have yet to adopt this standardization.

Using flammable and inflammable to mean the same thing is confusing.  The preferred wording is flammable and non-flammable.  Borrowing from semiotics, danger should be indicated with red, safety with green.

Portmanteau

Portmanteau (pronounced pawrt-man-toh)

(1) A case or bag to carry clothing in while traveling, made usually from stiff leather, hinged at the back so as to open out into two compartments

(2) A word created by blending two or more existing words.

1580s (for the travelling case (flexible traveling case or bag for clothes and other necessaries)): From the Middle French portemanteau (travelling bag, literally "(it) carries (the) cloak").  The original meaning from the 1540s was “court official who carried a prince's mantle" from porte, (imperative of porter (to carry) + manteau (cloak)).  The correct plural is portmanteaux but in modern English use, portmanteaus (following the conventions for constructing plurals in English) is now more common.  In the nineteenth century, the word was sometimes Englished as portmantle, a use long extinct.  The notion of the portmanteau word (word blending the sound of two different words) was coined by Lewis Carroll (pen-name of Charles L. Dodgson; 1832-1898) in 1871 for the constructions he invented for Alice Through the Looking-Glass such as Jabberwocky, his poem about the fabulous beast the Jabberwock.  Portmanteau in this sense has existed as a noun since 1872.

Vintage Louis Vuitton Portmanteau, typically circa US$50-80,000 depending on condition.

A portmanteau word, a linguistic blend, differs from contractions and compounds.  Contractions are formed from words that would otherwise appear together in sequence, such as do + not to make don't, whereas a portmanteau word is joins two or more words that relate to the one contractual theme.  A compound word is merely the joining for words in their original form (eg under + statement) without any truncation of the blended words.  Portmanteau words (eg breakfast & lunch to create brunch) always modifies at least one of the original stems.

Lindsay Lohan's handy moniker Lilo (the construct being Li(ndsay) + Lo(han) and it's used sometimes as LiLo) is a portmanteau word.

The word portmanteau was first used in this sense by Lewis Carroll in Alice Through the Looking-Glass (1871) where the concept is helpfully explained by Humpty Dumpty.  Less erudite but just as amusing was the creation of refudiate by Sarah Palin when she got confused and conflated refute and repudiate although it’s unclear whether she knew the meaning of either.  Even those created or used by more literate folk are not always accepted.  Irregardless (portmanteau of regardless and irrespective) seems to stir strong feelings of antipathy in pedants who generally won’t accept it even as a non-standard form and insist it’s simply wrong.  Other languages also create blended forms as needed.  The title of Emile Habibi’s 1974 novel was translated from Arabic utashaʔim (pessimist) + mutafaʔil (optimist) into English as The Pessoptimist.  Arabic linguistic traditions however prefer acronyms and compounds which sometimes overlap.  The group known variously as ISIL or ISIS (although they came to prefer "caliphate" or "Islamic State" (IS)) first adopted the name ad-Dawlah al-Islāmiyah fī 'l-ʿIrāq wa-sh-Shām (Islamic State if Iraq and the Levant) which is usually written as Daesh or Da'ish.  IS think this derogatory as it resembles the Arabic words daes (one who tramples underfoot) and dāhis (those who sows discord).  IS threatened to punish those who use Daesh or Da'ish with a public flogging; repeat offenders promised the cutting out of the tongue.

In the manufacture of big words, English is unlikely ever to match the Germans.  Until changes in EU regulations rendered it obsolete, the longest word in the Fourth Reich was rindfleischetikettierungsueberwachungsaufgabenuebertragungsgesetz (law delegating beef label monitoring).  Currently, the longest word accepted by German dictionaries is kraftfahrzeughaftpflichtversicherung (automobile liability insurance), editors rejecting donaudampfschifffahrtsgesellschaftskapitaenswitwe (widow of a Danube steamboat company captain) because of rarity of use.

Podophilia

Podophilia (pronounced podd-ah-fil-ee-uh or pod-oh-fil=ee-uh)

A paraphilia describing the sexualized objectification of feet (and sometimes footwear), commonly called foot fetishism although the correct clinical description is now "foot partialism".

The construct was podo- + -philia.  Podo- (pertaining to a foot or a foot-like part) was from the Ancient Greek πούς (poús), from the primitive Indo-European pds.  It was cognate with the Mycenaean Greek po, the Latin pēs, the Sanskrit पद् (pad), the Old Armenian ոտն (otn) & հետ (het), the Gothic fōtus and the Old English fōt (from which Modern English gained foot).

The Greek poús was the ancient Greek and Byzantine unit of length originally based upon the length of a shod foot and the idea in Europe endured for centuries although until the seventeenth century there were little attempts at standardization, even within the one jurisdiction and although things were settled well before the twentieth century, in the legal sense it wasn't until 1959 that the US, Canada, New Zealand, South Africa, Australia and the UK signed the "International Yard and Pound Agreement" which codified avoirdupois weight and length then used in all those nations, a set (although largely supplanted by the metric system (except in the US)) which officially still defines both Imperial and US customary units.  This English phrase "length of the chancellor's foot" was an allusion to this history though not actually concerned with lineal measurement.  It was instead coined by the lawyer John Selden (1584–1654) to illustrate how the Court of Chancellery which administered the flexible, adaptable law of equity differed from the rigid, precedent-bound courts of common law.  Equity is a roguish thing; for law, we have a measure to know what to trust to. Equity is according to the conscience of him who is Chancellor: as it is larger or narrower so is equity. It’s all one as if they should make the standard for the measure, we call afoot to be the Chancellor’s foot.”  In other words, in the Court of Chancellery, equity was administered by the Lord Chancellor at his discretion.  That did mean the estimation of equity could vary from one Chancellor to next and thus the Court of Chancellery soon created its own contradictions and attracted its own critics.

The suffix –philia was from the From Ancient Greek φιλία (philía) (fraternal love), from φλέω (philéō) (to love), from the earlier Ionic Greek (where the meanings diverged somewhat over the years.  It was used to to form nouns meaning a fondness, liking or love of something and in pathology picked up the specific technical sense of abnormal liking or tendency such a paraphilia.  One with specific attraction to feet or footwear is a podophile and their predilections are described as podophilic.

Often focused on toe cleavage, many self-described foot fetishists provide curated content.

Although the psychiatric community has since the mid-twentieth century devoted some time to discussing, re-defining and pondering what is apparently the 1800-odd year history of foot fetishism, a glance at the literature does suggest it’s been thought usually an interesting quirk in the human condition rather than a condition, much less a mental disorder.  Before the American Psychiatric Association (APA) in 1987 published the revised third edition of the Diagnostic & Statistical Manual of Mental Disorders (DSM-III-R), fetishism was usually described as a persistent preferential sexual arousal in association with non-living objects or an over-inclusive focus on (typically non-sexualized) body parts (most famously feet) and body secretions.  With the DSM-III-R, the concept of partialism (an exclusive focus on part of the body) was separated from the historic category of fetishism and appended to the “Paraphilia Not Otherwise Specified” category.  Although one of the dustier corners of psychiatry, the field had always fascinated some and in the years since the DSM-III-R was published, a literature did emerge, most critics maintaining partialism and fetishism are related, can be co-associated, and are non-exclusive domains of sexual behavior.  There was a technical basis for this position because introduced in DSM-IV (1994) was a (since further elaborated) codification of the secondary clinical significance criterion for designating a psychiatric disorder, one the implications of which was that it appeared to suggest a diagnostic distinction between partialism and fetishism was no longer clinically meaningful or necessary.  The recommendation was that the prime diagnostic criterion for fetishism be modified to reflect the reintegration of partialism and that a fetishistic focus on non-sexual body parts be a specifier of Fetishism.

Fetish was from the Latin facere (to make) which begat factitious (made by art), from which the Portuguese feitico was derived (fetiche in the French), from which English gained fetish.  A fetish in this context was defined as "a thing irrationally revered; an object in which power or force was concentrated".  In English, use of fetish to indicate an object of desire in the sense of “someone who is aroused due to a body part, or an object belonging to a person who is the object of desire” dates from 1897 (although the condition is mentioned in thirteenth century medical documents), an era during which the language of modern psychiatry was being assembled.  However, the earliest known literary evidence of podophilia lies in dozens of brooding, obsessive love letters from the second century AD of uncertain authorship and addressed to both male and female youths.  That there are those to whom an object or body part has the power to captivate and enthral has presumably been part of the human condition from the start.

From the beginnings of modern psychiatry, such a focus was not in itself considered a disorder, unless accompanied by distress or impairment although it was noted by many that if even a nominally “harmless” fetish became an obsession, it certainly could impair healthy sexuality.  In DSM-5 (2013), the diagnosis was assigned to individuals who experience sexual arousal from objects or a specific part of the body which is not typically regarded as erotic and presumably any body part or object can be a fetish, the most frequently mentioned including underwear, shoes, stockings, gloves, hair and latex.   Fetishists may use the desired article for sexual gratification in the absence of a partner although it’s recorded this may involve nothing more than touching smelling the item and the condition appears to manifest almost exclusively in men, the literature suggesting a quarter of fetishistic men are homosexual but caution needs always to be attached to these numbers.  Because fetishism is something which many happily enjoy their whole adult lives, it never comes to the attention of doctors and a high proportion of the statistical material about fetishism is from patients self-reporting.  The statistics in a sense reflect thus not the whole cohort of the population with the condition but rather those who either want to talk about it or are responding to surveys.  That is of course true of other mental illnesses but is exaggerated with fetishism because so much lies with the spectrum of normal human behavior and the definitional limitations in the DSM-5 reflect this, including three criteria for Fetishistic Disorder and three specifiers:

Criterion 1: Over a six month period, the individual has experienced sexual urges focused on a non-genital body part, or inanimate object, or other stimulus, and has acted out urges, fantasies, or behaviors.

Criterion 2: The fantasies, urges, or behaviors cause distress, or impairment in functioning.

Criterion 3: The fetishized object is not an article of clothing employed in cross dressing, or a sexual stimulation device, such as a vibrator.

Specifiers for the diagnosis include the type of stimulus which is the focus of attention (1) the non-genital or erogenous areas of the body (famously feet) and this condition is known also as Partialism (a preoccupation with a part of the body rather than the whole person), (2) Non-living object(s) (such as shoes), (3) specific activities (such as smoking during sex).

Not AOC’s feet.

The foot particularists also do PSAs (public service announcements).  When an image of feet was posted to Instagram with a caption claiming they belonged to Alexandria Ocasio-Cortez (AOC, b 1989, US Representative (Democrat-New York) since 2019 and one of "the squad"), the alleged foot-selfie was lent a whiff of scandal by their owner being in the bath, holding a vape with a bottle of pumpkin-scented shampoo nearby.  The story quickly was debunked by the online foot fetishists at WikiFeet, the internet’s most comprehensive collection of pictures of women's feet.  In this case, Ms Alexandria Ocasio-Cortez’s Wikifeet page was used to compare and contrast and it wasn’t a difficult task for the Wikifeet experts because the toes in the image were mildly brachydactyly (an inherited trait whereby the bones of the digits are relatively short) whereas AOC’s are not so afflicted.  Wikifeet’s users rate AOC’s feet at “4 stars” (nice feet), based on the 78 images in her page (many in sandals but some daringly bare).  Further research by the Wikifeet particularists revealed the feet really belonged to Sydney Leathers (b 1991) who became even better known by parlaying the publicity she attracted for being the sexting partner of disgraced New York politician Anthony Weiner (b 1964) into an apparently brief career as an aspiring porn star.  Why that didn’t flourish isn’t clear because rarely has there been a better porn star name than "Sydney Leathers" and Australian fellmongers and fetishists alike missed a marketing opportunity there.

Noting the definitional model in the DSM-IV-TR (2000), despite the history in psychiatry’s world of paraphilias and a notable presence in popular culture, there were those who claimed the very notion of a foot fetish was false because of that critical phrase “non-living” which would seem to disqualify a foot (unless of course it was no longer alive but such an interest would be seriously weird and a different condition; although in this context there are deconstructionists who would make a distinction between a depiction of a live foot and the foot itself, clinicians probably regard them as interchangeable tools of the fetishist although the techniques of consumption would vary).  The critic noted many fetishes are extensions of the human body, such as articles of clothing or footwear but that did not extend to feet and that diagnostically, a sexual fascination with feet did correctly belong in the category of “Paraphilia Not Otherwise Specified,” and thus be regarded as partialism: Foot partialism.

It was Sigmund Freud (1856-1939) who admitted that, lawfulness aside, as animals, the only truly aberrant sexual behavior in humans could be said to be its absence (something which the modern asexual movement re-defines rather than disproves).  It seemed to be in that spirit the DSM-5 was revised to treat podophila and many other “harmless” behaviors as “normal” and thus within the purview of the manual only to the extent of being described, clinical intervention no longer required.  Whether all psychiatrists agree with the new permissiveness isn’t known but early reports suggest there’s nothing in the DSM-5-TR (2022) to suggest podophiles will soon again be labeled as deviants.
