Anadrome

Anadrome (pronounced an-uh-drohm)

(1) A word which forms a different word when spelled backwards.

(2) In pre-modern medical jargon, the upward path of various elements (pain, blood etc) (obsolete).

Circa 1961 (in this context): The construct was ana- +‎ -drome.  Ana was from the Ancient Greek ἀνα- (ana-), from ἀνά (aná) (backward in direction, reversed) and drome was from the Ancient Greek δρόμος (dromos) (running; racetrack); the surface analysis of anadrome thus can be understood as “going backwards”.  Confusingly however, the Greek prefix aná was appended also to convey the notion of “up, above, upward”, (2) “again”, (3) “thoroughly”, (4) “against”, (5) “distal, away from” and (6) “to grow or change in place; functionally similar”.  So, a deconstruction alone would not be definitive and the meaning is established through context.  The longest accepted anadrome in English is believed to be the pair desserts/stressed but among the dozens which exist, it is god/dog which seems most to amuse students.  The coining of anadrome was credited to Martin Gardner (1914–2010) who is said to have added it in a 1961 re-publication of Oddities and Curiosities of Words and Literature (1875) by Charles C. Bombaugh (1828-1906) but the word doesn't appear in at least some of the 1961 editions and at least the spike in use may better be attributed to the reclusive and eccentric Dmitri Borgmann (1927–1985) a German-American author regarded still as something of the “high priest of recreational linguistics”.  In his introduction, Mr Gardner does pay tribute to Mr Borgmann as one of the “outstanding creators of word puzzles”.  Anadrome & anadromy are nouns and anadromous & anadromic are adjectives; the noun plural is anadromes.

An young anadromous Atlantic salmon, still resident in the freshwater in which it was born.  The young salmon are called smolts after they gain a silvery hue and migrate to the ocean.

The adjectival form is used in ichthyology, the term “anadromous fish” describing those species born in freshwater rivers or streams that migrate to the ocean to mature and forage, subsequently returning to freshwater to spawn.  First appearing in scientific papers in 1753, the construct of anadromous was ana- (used here in the sense of “up, above, upward”) + dromos (a running), from dramein (to run).  Though the usual natural processes, anadromous fish have evolved with an environmental adaptation called osmoregulation which enables them seamlessly to adapt to changing salinities; that’s what makes it possible for them to live in both aquatic habitats (salt & freshwater).  The process is dynamic as it must be because while some notional freshwater species might move into a sea or ocean only for weeks, others can stay there for years because that’s where they undergo most of their growing cycle.  Remarkably, and using a mechanism not wholly understood (use of the Earth’s magnetic field an intriguing theory), after perhaps years the fish return to their exact natal streams to reproduce.  For freshwater ecosystems, the behaviour is not a mere zoological curiosity because as schools return from their time in saltwater, they bring with them marine-derived phosphorus & nitrogen, “topping up” the elements on which the health of the spawning grounds depends.  Anadromous fish are thus listed as keystone species, some salmon the best known examples.  An anadromic fish swimming to or from the ocean could be said to be proceeding anadromically but the adverb is non-standard.

A catadromous freshwater American eel, slithering out of a pipe, possibly heading back to the ocean, catadromically (again, a non standard adverb).

The companion term is “catadromous fish”, describing species born in salt water that mature in fresh water and return to the sea to spawn, certain eels the best known.  The mysterious European eel exerted a particular fascination upon the natural scientists of Antiquity, Aristotle (384-322 BC) writing the earliest known study although the findings truly were speculative, his novel idea being the creatures were born of “earth worms” which, he suggested, were formed of mud, growing from the “guts of wet soil”.  In the absence of any better theory or observational data, the notion for some time held sway and not for centuries was spontaneous generation disproven.  It wasn’t until the eighteenth century researchers perfected their techniques of dissection and confirmed eels really are fish although, while in recent years it has been possible to effect breeding of eels in captivity, because of the difficulty of replicating at scale the multi-aquatic environment needed for the life-cycle, it’s unlikely any time soon to become commercially viable.  Largely because of demand from the Far East (especially Japan) the European freshwater glass eel has become threatened with smuggling rife, the decline in availability encouraging a trade in the American eel, something which has created problems because of the involvement of transnational crime groups.

Although in a sense belonging to the discipline of structural linguistics, the word anadrome (in this context) seems to have been coined only in the mid twentieth century and it emerged not from academia but recreational wordplay: it was a “fun word” which migrated to reference books when editors and compliers noticed it appearing in published word games, logology and puzzle culture.  While it has no place in formal linguistic theory, it is used as a teaching aid, apparently on the basis it “trains the mind to be flexible”.  The model is believed to be the better known “palindrome” (a word, line, verse, number, sentence, etc reading the same backward as forward).in used since the 1630s.  In logology (recreational linguistics, puzzle and word-game writing etc), there is a great satisfaction in having a coined word “succeed” in the sense of even a limited, specialized acceptance which is why the community has come up with synonyms including: (1) semordnilap (“palindromes” spelled backwards) (2) levidrome (the “Levi” element from the given name of the coiner), (3) reversgram and (4) heteropalindrome (the hetro- prefix a learned borrowing from Ancient Greek τερος (héteros) (other, another, different).  There was a suggestion such words should be called "a volta" (from the Italian volta (to turn)) but the idea never caught on. 

Google Ngram

Google Ngram (a quantitative and not qualitative measure): Because of the way Google harvests data for their Ngrams, they’re not literally a tracking of the use of a word in society but can be usefully indicative of certain trends, (although one is never quite sure which trend(s)), especially over decades.  As a record of actual aggregate use, Ngrams are not wholly reliable because: (1) the sub-set of texts Google uses is slanted towards the scientific & academic and (2) the technical limitations imposed by the use of OCR (optical character recognition) when handling older texts (typically a scanner might misread an “f” for a long “s” or a “u” for an “n”) of sometime dubious legibility (a process AI (artificial intelligence) should improve).  Where numbers bounce around, this may reflect either: (1) peaks and troughs in use for some reason or (2) some quirk in the data harvested.

As Google’s Ngram reports, “anadrome” was in use in the nineteenth century, the earliest citation dating from 1840, the use a classic illustration of “lexical overlap” a phenomenon which delights word nerds (an easily delighted lot).  In the mid-late 1800s, anadrome (often written as anadromé, reflecting both the Greek roots and the backgrounds of those using the word) was a technical term seen mostly in botanical and medical publications; it was direct borrowing of the Ancient Greek anadromē (ναδρομή) (“an ascent”; “running up”).  Medical dictionaries in the era weren’t new but revised editions were common because advances in observational technologies and techniques meant new entries constantly were required and anadrome seems first to have been used of a variety of “physiological ascents” including (1) Ascending Pain: physical pain starting in the lower limbs or torso and migrating upward, (2) The “upward determination of blood: A rush of blood toward the head or upper body and, best of all (3) Globus Hystericus: The “lump in the throat” sensation described at the time also as the “ascent of the womb”.  Although scientifically inaccurate it was memorable and dated from the era (which lasted well into the twentieth century) when the condition “hysteria” was part of the diagnostic toolkit for physicians assessing female patients.  In botanical use, the meaning was most analogous with the idea of blood flow, botanists describing “sap flow (the ascent of sap through a plant’s vascular system).  What the Ngram has in this case captured is a genuine heteronym (a word that looks the same but has a completely different meaning and subtly different lineage).

Between consenting players only: At least 11 points but don’t try insisting on it in competition or you’ll be blackballed; the Scrabble crew neither forgive nor forget.

The proliferation of synonyms of a word which is little more than a curiosity is an example of why the English language has so many words most are which are never or rarely used.  The estimates notoriously are vague because there exists no consensus on just what is the definition of a “real word” (which sounds silly but in language there’s no concept like the “real number” in mathematics and, at the margins, disputes are legion).  If one is most accommodating of the definitional spectrum, there may in English be as many as a million words but only 15-20% are thought to be in regular or occasional use.  However, although it has appeared in many lists (often of the strange or obscure) anadrome has not received the imprimatur of the major sanctioning bodies for the game of competitive Scrabble.  It never appeared in the Collins SOWPODS (an anagram of the two abbreviations OSPD (Official Scrabble Players Dictionary) & OSW (Official Scrabble Words)) or the replacement CSW (Collins Scrabble Words) and nor is it in the NASPA’s (North American Scrabble Players Association) NWL (NASPA Word List).  The NASPA Dictionary Committee does accept submissions so anadrome advocates can pursue that course but as a non-standard form, the adverb anadromically has no good prospects.  Why Collins drove the wonderful sounding SOWPODS to extinction remains a mystery. Those playing at home can of course accept a bit of linguistic promiscuity and, provided all players agree, if used, it’d be at least an 11 point score (before any double/triple letter or word bonuses).  For word nerd dissidents unhappy with the dictatorial ways of Scrabble’s ruling ancien régime, there is the scrabblesque (also not a “real word”) “Anadrome the Game” in which anadromes attract high scores.

A brunette era Lindsay Lohan wearing Nahol dress in a black and white rose print by Masai of Copenhagen, rendered as a line drawing by Vovsoft.  The anadrome of “Lohan” is “Nahol”.

Masai describes the Nahol as “a loose, oversized, and comfortable midi-dress, characterized by a V-neck, ¾-length length sleeves, side pockets and an elasticized hem creating a slight balloon effect.  That it has pockets may be enough of a selling point for women, many designers loath to include them in women’s clothing because any additional bulk might “spoil the line”.  Made with what the manufacturer describes as a “sustainable” (a word that has become the industry’s “new black”) mix of 15% polyamide blend & 85% viscose (said “often” to be FCS (Forest Stewardship Council) certified), the material had a “crinkled” finish in black or printed designs.  It does look comfortably accommodating and, on the move, would "swish" nicely.

Nahol as a proper noun (surname): Dalia Nahol.

While not a recognized word in English or other European languages, Nahol is a proper noun and the village of Nahol (bp) (नहोल (bp) is in the Shimla District of Himachal Pradesh State, India.  In the anthropological record, it seems most often mentioned as used a name in PNG (Papua New Guinea) and East Africa although many of those texts were derived from oral histories so what was recorded as a phonetic “Nahol” may in some cases have been variants.  Whether there’s any link in origin between the uses in PNG & East Africa isn’t known and as a relatively simple (five letter, two syllable) form, it is likely Nahol came independently to be used as a name in more than one place.  The best documented origin is from Ethiopia where the name Naol often was transliterated as Nahol, Nawol or Naoll; it’s a masculine form from Oromo culture meaning “one who brings the peace” or “peaceful”. 

Nahol as a proper noun (surname): Isaac Amu Nahol.

There is an ancient linkage between Jewish traditions and Ethiopia but there’s no evidence the surname Nahols (most prevalent in Eastern Europe, notably among Jewish communities in Poland and Ukraine) has any connection with the Oromo culture; the similar form Nahal (or Nahaul) from the Hebrew (נחל) (nahal) meaning “stream, brook, valley” (and, by extension, “inheritance” (the idea of an estate “flowing” to the descendants)).  Nahols may have been derived from a Yiddish or Hebrew personal name (on the model of English names such as Stevenson (ie the son of Steven)).  In Arabic, the cognate root yielded Nahel & Nahil which although often understood as “generous” or “successful”, is linked also to “bees & honey”, the latter perhaps accounting for why one Bangladeshi source cites the name Nahol meaning “the queen of bees”.

Palindrome

Palindrome (pronounced pal-in-drohm)

(1) A word, line, verse, number, sentence etc, reading the same backward as forward.

(2) In biochemistry, a region of DNA in which the sequence of nucleotides is identical with an inverted sequence in the complementary strand.

1638: From the Ancient Greek παλίνδρομος (palindromos) (running back again; recurring, literally “literally "a running back”) the construct being πάλιν (pálin) (again, back) + δρόμος (dromos) (direction, running, race, racecourse).  Pálin was from the primitive Indo-European kwle-i-, a suffixed form of the root kwel- (revolve, move round) (kw- becomes the Greek p- before some vowels.  The word palindrome was first published by Henry Peacham (1578-circa 1645) in The Truth of Our Times (1638).  Although derived from the Greek root palin + dromos, the Greek language uses καρκινικός (carcinic, literally “crab-like”) to refer to letter-by-letter reversible writing.  The related palinal (directed or moved backward, characterized by or involving backward motion) dates from 1888.  The noun palinode (poetical recantation, poem in which the poet retracts invective contained in a former satire) dates from the 1590s and was from either the sixteenth century French palinod or the Late Latin palinodia, from the Greek palinōidia (poetic retraction), again from pálin; the related form were palinodical & palinodial.  The word palinode was sometimes applied to the apologies artists and others in the Soviet Union were compelled to publish, often after being accused of formalism or something just as heinous.  Palindrome & palindromist are nouns, palindromically is an adverb and palindromic an adjective.

Pierre Laval (1883–1945; Prime Minister of France 1931-1932, 1935-1936 & de facto prime minister in the Vichy Government 1942-1944).

Even before he spent the final years of his political career as a senior official in the collaborationist regime of Vichy France under Marshal Philippe Pétain (1856-1951), the palindromic Laval was already notorious for his dubious financial dealings while in government and being a party to the Hoare–Laval Pact (1935), concocted with the then British Foreign Secretary Samuel “Slippery Sam” Hoare (1880-1959) with which the pair sought to end the tiresome Second Italo-Ethiopian War (the last of the colonial land-grabs in the era of European colonization) because it was “bad for business”.  Something of a precursor to the 1938 Munich Agreement in which the UK and France acquiesced to the Nazi’s dismemberment of Czechoslovakia in exchange for what, delusionally, they believed would be Adolf Hitler’s (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) final territorial claim in Europe, what the Hoare–Laval Pact offered was a partition of Abyssinia, something which in retrospect would have been merely the first step to Benito Mussolini (1883-1945; Duce (leader) & Prime-Minister of Italy 1922-1943) absorbing the whole country as a colony of Imperial Italy.  Even for the, by then jaded, people of France and the UK the cynicism was too blatant and the reaction when the details were made public ensured both ministers were dismissed.

Otto Abetz (1903-1958; de facto German ambassador to Paris 1940-1944, left) shaking hands with Marshal Pétain (right), Paris, November 1941.

Pétain had little faith in the arrangements his regime negotiated with the Germans honored, telling colleagues after one meeting: "It will take six weeks to work out all the details and six months for the Germans to forget all about them."  Because Berlin didn't formerly created diplomatic relations with France after the defeat in 1940, Otto Abetz was never properly credentialed as ambassador but wholly he discharged the duties.  His great nephew is Eric Abetz (b 1958; Liberal Party senator for Tasmania, Australia 1994-2022, Treasurer of Tasmania since 2024).

Hoare was an accomplished ice-skater and made a political comeback as did Laval who, sniffing the winds of French defeat in 1940, became a convinced fascist, serving in the Vichy regime between July 1940-August 1944 variously as vice-president of the Council of Ministers and head of government.  He fled to Spain after the Liberation of France but was extradited and put on trial for plotting against the security of the state and collaborating with the Nazis; found guilty, he was executed by firing squad in October 1945.  Old Marshal Pétain fared a little better.  Although also sentenced to death for his role during the occupation, Charles de Gaulle (1890-1970; President of France 1959-1969), then serving as Chairman of the Provisional Government of the French Republic, couldn’t bring himself to sign the death warrant for one of the country’s heroes of World War I and commuted the sentence to life imprisonment, officially on the grounds of “age”.

Perhaps surprisingly, the longest known palindromic word is not German despite their fondness for lengthy compounds.  According to the Guinness Book of World Records the record is held by the 19 character saippuakivikauppias which is Finnish for “a travelling salesman who sells lye (caustic soda)”.  It’s said not often to come up in conversation and seems to exist only a curiosity used in lists of long palindromes where it's the undisputed number one.  In English, palindromes of a few characters are common but examples with more than seven letters are rare.  Tattarrattat (the sound made by knocking on a door), as it’s usually spelled, has 12 characters but is a bit of a fudge because it’s also an onomatopoeia so some lexicographers insist it doesn’t count.  Also cheating but clever is the 11 letter aibohphobia meaning a fear of palindromes, the construct being the suffix -phobia + its reverse.  Adding to the charm is that it’s doubtless a non-existent condition, but it’s suspected there are anyway a few of those in the literature of psychiatry.  From India, there's kinnikinnik, a smoking mixture of bark & leaves (but no tobacco).  English’s longest “real” palindrome appears to be detartrated, the past participle of detartrate (to remove tartrates (salts of tartaric acid)), especially from fruit juices and wines, in order to reduce tartness or sourness).  Not only is it a real word but it describes a common process in the industrial production of foods and beverages.

Announced on an auspicious date.

On 2 February 2020, Lindsay Lohan (b 1986), in a now deleted Instagram post, for the first time publicly acknowledged her relationship with Bader Shammas (b 1987), a group photograph from Dubai, including the couple and her sister Aliana (b 1993), captioned: "@aliana lovely night with sister and my boyfriend bader💗".  The couple would later marry.  2 February 2020 (02-02-2020) was the twenty-first century’s only eight-digit global palindrome (ie it works with either the MM-DD-YYYY or DD-MM-YYYY convention).  The last eight-digit global palindrome happened 908 years earlier on the even more numerically symmetrical 11 November 1111 (11-11-1111) and the next one will be 908 years hence on 3 March 3030 (03-03-3030).  Six and seven digit palindromes are more common.

Palindromic sentences are often created and these are judged not by length but by their elegance.  Leigh Mercer (1893–1977) was a word nerd and recreational mathematician who devised the classic "A man, a plan, a canal: Panama!" and this approach was in the 1980s taken to its logical extreme in two novels, Satire: Veritas (1980, 58,795 letters) by David Stephens and Dr Awkward & Olson in Oslo (1986, 31,954 words) by Lawrence Levine, both said to be palindromically perfect and wholly nonsensical.  Shorter, but of admirable clarity, are the many baptismal fonts in Greece and Turkey which bear the circular 25-letter inscription NIYON ANOMHMATA MH MONAN OYIN (Wash (my) sins, not only (my) face).  This appears also in several English churches.

Sixteenth century German "oath skull" on which defendants swore their oaths in the Vehmic courts (the Vehmgericht, Holy Vehme or Vehm, the alternative spellings being Feme, Vehmegericht & Fehmgericht), a tribunal system established in Westphalia during the late Middle Ages.

Created essentially because of the inadequacies of the official justice system, they're now often referred to as "proto-vigilante" courts but for centuries they filled a niche before they came increasingly to be associated with injustice and corruption before finally being abolished in 1811, a half-decade after the dissolution of the Holy Roman Empire, the source of their original authority.

The pattern on the skull was based on a multi-directional palindromic grid created by some word nerds in Ancient Rome.  Later re-discovered etched onto a wall in the doomed city of Herculaneum, it reads Sator Arepo Tenet Opera Rotas (The sower, Arepo, makes the wheel work) and it works whether read vertically, horizontally, or in the diagonal.  These types of palindromic squares are called pentacles and the SATOR was the most commonly found in the Western Esotericism of late antiquity.  They were used by Kabbalists, Gnostics, alchemists and other pre-medieval mystics in the creation of magic spells, amulets, potions etc and were thus often seen in the shops of apothecaries.

sator: sower/planter
tenet: he/she/they/it holds/has/grasps/possesses
opera: work/exertion/service
rotās: wheels

There has been speculation about the the meaning of this pentacle, some a little fanciful, but the consensus is things were made up just to fit, rather as "the quick brown fox jumps over the lazy dog" was coined to use each letter in the alphabet and "DICK HOOD DID EXCEED" serves no purpose other than to appear the same if inverted and viewed in a mirror.  The truly palindromic never odd or even” spelled backwards remains “never odd or even”.
