Ambiguous

Ambiguous (pronounced am-big-yoo-uhs)

(1) Open to or having several possible meanings or interpretations; equivocal.

(2) In linguistics, of an expression exhibiting constructional homonymity; having two or more structural descriptions.

(3) Of doubtful or uncertain nature; difficult to comprehend, distinguish, or classify.

1528: From the late Middle English ambiguous (of doubtful or uncertain nature, open to various interpretations) Latin ambiguus (moving from side to side, of doubtful or uncertain nature, open to various interpretations), from ambigere (to dispute about (figuratively "to hesitate, waver; be in doubt" and literally “to wander; go about; go around”) the present active infinitive of ambigō from ambi (around) +‎ agō or agere (I drive, move).  The first known citation in English is in the writings of Sir Thomas More (1478-1535) in 1528 but most scholars maintain the noun ambiguity had been in use since circa 1400 in the sense of "uncertainty, doubt, indecision, hesitation", from the Old French ambiguite and directly from Latin ambiguitatem (nominative ambiguitas) (double meaning, equivocalness, double sense), the noun of state from ambiguus (having double meaning, doubtful),  The meaning "obscurity in description" emerged in the early fifteenth century.  The adjective unambiguous dated from the 1630s while the noun disambiguation (removal of ambiguity) is documented since 1827.  Ambiguous is an adjective, ambiguate is a verb and ambiguity, ambiguation & ambiguousness are nouns; the most common noun plural is ambiguities. 

Structural ambiguity, syntactic ambiguity & lexical ambiguity

Lindsay Lohan in pink orchid veavage swimsuit next to potted pink orchid, Phuket, Thailand, December, 2017.  It was during this holiday the wire services reported “Lindsay Lohan bitten by snake on holiday in Thailand”; almost instantly, the grammar Nazis tweeted on X (then known as Twitter) demanding proof the snake really was on holiday; standards had fallen since sub-editors went extinct.  Ms Lohan made a full-recovery; there was no word on the fate of the (presumably not venomous) serpent.

One of the core concepts in structural linguistics is that the meaning of many combination or words (ie a compound, sentence or phrase) is derived not merely from the meanings of the individual words but also from the way in which they’re combined.  It’s a simple idea which academics have managed to make sound complex, calling the process “compositionality” (that meaning is a construct of word meanings plus morphosyntactic structures).  So, because a structure can contribute to meaning, it follows that changing the order of the words can lead to a different meaning even if the same words are used.  When a word, phrase, or sentence has more than one meaning, it is ambiguous and “ambiguous” has a specific meaning in structural linguistics because it doesn’t mean simply that a meaning is vague or unclear: It means two or more distinct meanings are available and this is called structural ambiguity or syntactic ambiguity (as distinct from when a word has more than one distinct meaning which is known as lexical ambiguity.  Sometimes, the intended meaning can be unclear but often context can be used to assist the deconstruction and although technically ambiguous, most readers probably understood what happened in the "Lindsay Lohan snake incident".

China, the renegade province of Taiwan and strategic ambiguity

Taiwan (aka Formosa) is an island off the coast of China which separated, politically, from the mainland in 1949.  The Chinese government regards Taiwan as “a renegade province”; the island’s administration maintains a position of structural autonomy without actually declaring independence.  Since 1950, the US has maintained a security guarantee for the de facto independence of Taiwan which has been sometimes explicit, sometimes vague, the latter paradigm known as a policy of strategic ambiguity.

The origins of the guarantee lie in the Korean War.  In 1950, Dean Acheson (1893–1971; US secretary of state 1949-1953) delineated the US security perimeter in Asia and included neither Taiwan nor South Korea.  Chinese leader Chairman Mao (Mao Zedong 1893–1976; chairman of the Chinese Communist Party (CCP) 1949-1976) and Kim Il-sung (Kim I, 1912–1994; Great Leader of DPRK (North Korea) 1948-1994), in an interpretation endorsed by their senior partner, Comrade Stalin (1878-1953; Soviet leader 1924-1953), concluded Washington would not defend either country.  The DPRK acted first, invading South Korea in June 1950 which shocked the US into assembling a military response under the flag of the UN and, fearing further Communist incursions in Asia, sent the Seventh Fleet to deter any attempt by Peking to invade Taiwan.

In 1954, China probed US policy by shelling some Taiwanese islands in what came to be known as the First Taiwan Strait Crisis; the US responded by entering into defense treaties with both Taiwan and South Korea.  The probing continued, notably with the second crisis in 1958 and in the 1960 presidential campaign, both candidates, Richard Nixon (1913-1994; US president 1969-1974) and John Kennedy (JFK, 1917–1963; US president 1961-1963), pledged to defend Taiwan against Chinese aggression.  During the 1960s, in a kind of military choreography, US-China standoffs continued.  By 1972, things had changed.  The US sought China’s assistance, both to extricate themselves from the quagmire of the Vietnam War and to become something of a strategic partner against the USSR, Peking having long split from Moscow.  In a communique issued from Shanghai, Washington affirmed Peking’s “one China” principle that Taiwan is part of China saying it was a matter for China and Taiwan to work out the relationship peacefully. 

The nine dash line.

Despite that, the US-Taiwan Treaty remained but it needed now to be viewed in the context of Richard Nixon's Guam Doctrine, issued in 1969, in which the president noted "…the US would assist in the defense… of allies and friends" but would not "undertake all the defense of the free nations of the world."  For Taiwan, and presumably everyone else, strategic ambiguity thus began.  Seven years after the Shanghai statement, later, the Carter administration recognized the People’s Republic of China (PRC, the old Red China), severed formal diplomatic relations with Taiwan and terminated the treaty.  Strategic ambiguity has shrouded Washington’s position on Taiwan ever since.  US presidents have on occasion suggested both something more robust and something less so it appears to remain the position that the US might defend Taiwan were China to invade but it might not.  It would depend on the circumstances.  For seventy-odd years, the US position has been enough to deter China from exercising the military option to restore the renegade province to the motherland but a multi-dimensional chess game will play-out over the next decade in the South China Sea.

Twelvemonth & Year

Twelvemonth (pronounced twelve-month)

Twelve months (one year).

Pre 1050: From the Middle English twelmonth, twelfmonthe, twelfmonþe or twelv′munth, from the Old English twelfmōnþ or twelfmōnaþ.  The construct was twelve +‎ month. Twelve was from the Middle English twelve, from the Old English twelf (twelve), from the Proto-Germanic twalif, an old compound of twa- (two) + -lif (left over (in the sense of the two left over after having already counted to ten)) from the primitive Indo-European leyp- (leave, remain). It was cognate with the Saterland Frisian tweelf, tweelif & tweelich (twelve), the West Frisian tolve (twelve), the Dutch twaalf (twelve), the German & Low German twalf & twalv (twelve), the German zwölf (twelve), the Danish, Swedish and Norwegian tolv (twelve) and the Icelandic tólf (twelve).  Month was from the Middle English month & moneth, from the Old English mōnaþ (month), from the Proto-Germanic mēnōþs (month), from the primitive Indo-European mḗhins (moon, month), probably from meh- (to measure), a reference to the moon's phases as the measure of time, the construct understood as moon +‎ -th.  It was cognate with the Scots moneth (month), the North Frisian muunt (month), the Saterland Frisian mound (month), the Dutch maand (month), the Low German Maand & Monat (month), the German Monat (month), the Danish and Norwegian Bokmål måned (month), the Norwegian Nynorsk & Swedish månad (month), the Icelandic mánuði (month), the Latin mēnsis (month), the Ancient Greek μήν (mḗn), the Armenian ամիս (amis), the Old Irish mí and the Old Church Slavonic мѣсѧць (měsęcĭ).  Twelvemonth is a noun; the noun plural is twelvemonths.

The adverb was twelvemonthly which is not the same as twelve-monthly, another ill-defined construction which originally meant one thing annually done but was used by some in the sense of something done every month of the year.  It’s now regarded as an archaic or dialect word for year and seen only in historic texts or as a literary device. In the mid-twentieth century there was movement among some to offer it as a way offering more precision in language, the notion being that year would describe a calendar year (eg 1999) whereas September 1998-August 1999 would be a twelvemonth.  The idea never caught on.

Year (pronounced yeer)

(1) A period of 365 or 366 days, in the Gregorian calendar, divided into twelve calendar months, now reckoned as beginning 1 January and ending 32 December (the calendar or civil year).  The 366 day leap year happens (with a few exceptions) every four years; 29 February being the quadrennial addition.  The leap year (mostly) fixes the calendar and maintains it at the same length, mechanics of adjustments described in Medieval Latin as saltus lunae (omission of one day in the lunar calendar every 19 years) which in the Old English was monan hlyp. 

(2) A period of approximately the same length in other calendars; The traditional Chinese calendar, which determines the date of the Lunar New Year, is lunisolar (based on the cycle of the moon as well as on Earth's course around the sun).  A month on this Chinese calendar is 28 days long, and a normal year lasts between 353-355 days.  Other methods of calculation include from Tishiri 1 to Elul 29 in the Jewish calendar, and from Muharram 1 to Dhu al-Hijjah 29 or 30 in the Islamic.

(3) A period of 12 calendar months calculated from any point.

(4) In astronomy, also called the lunar year, a division of time equal to twelve lunar months and equal to 354.3671 days

(5) In astronomy, as tropical year (also known as a solar or astronomical year), the time the Sun takes to return to the same position in the cycle of seasons, as seen from Earth and equal to 365.242 (eg the time from vernal equinox to vernal equinox, or from summer solstice to summer solstice).

(6) In astronomy, as sidereal year, the time taken by the Earth to orbit the Sun once with respect to the fixed stars (equal to 365.256).  Hence, it is also the time taken for the Sun to return to the same position with respect to the fixed stars after apparently travelling once around the ecliptic; the time in which any planet completes a revolution round the Sun (eg the Martian year).

(7) With various modifiers (fiscal year, liturgical year, academic year etc), a period out of every twelve months, devoted to a certain pursuit, activity, or the like.

(8) A group of students entering school or college, graduating, or expecting to graduate in the same year (as in class of 2020).

(9) In English common law as legal year, a measure equal to a year and a day, the period fixed to ensure the completion of a full year. It was used in admiralty law to determine the time within which wrecks had to be claimed and in the criminal law to determine liability in murder cases; if the victim of an assault lived a year and a day from the assault, the perpetrator could not be charged with murder, even were the victim subsequently to die from his injuries.  The rule was translated to statute law in some jurisdiction and was repealed only because of advances in medical care and technology.

Pre 900: From the Middle English yeer, from the Old English gēar, gearlic & gear (yearly, of the year, annual).  It was related to the Gothic jēr, the Old Saxon & Old High German jār, the Old Norse ār (year), the Polish jar (springtime), the Latin hōrnus (of this year), the Dutch jaar, the German Jahr, the Gothic jēr and the Greek hôros (hṓrā) (year, season, part of a day, hour).  The alternative spellings were yeare, yeer, yeere & yere, all long obsolete.  Year & yearling are nouns and yearly is a noun, adjective & adverb; the common noun plural is years.

Twelvemonth does still get the odd use, usually as a novelty or deliberate anachronism.

Year-long (also yearlong) dates from 1813, year-round from 1917 and as an adverb from 1948.  The light-year (also lightyear), the distance light travels in one year (circa 5.87 trillion miles (944 trillion km)) was first defined in 1888.  Yearling (an animal a year old or in its second year) is attested from the mid-fifteenth century, the noun year-old in this sense being from the 1530s.  Yearbook (also year-book) dates from the 1580s as (book of reports of cases in law-courts for that year), the sense extended to other books of “accumulated events and statistics of the previous year" by 1710.  The first used in the sense of a “graduating class album" is attested from 1926, an invention of American English.  The Dutch schrikkeljaar (leap year) is from the Middle Dutch schricken (leap forward) which translates literally as "be startled, be in fear" and the 29 February is schrikkeldag.  The Danish skudaar & Swedish skottår translate literally as "shoot-year”; The German schaltjahr is from schalten (insert, intercalate) and the Late Latin phrase was annus bissextilis, source of the Romanic words.  One quirk in modern commerce is that payrolls tend to be administered in weekly or multiples of weekly cycles and for most purposes there are 52 weeks in a year.  However, the year (to four decimal places) is actually about 52.1775 weeks long so, every thirteen years-odd, accountants often have to ensure provision has been made for an additional payroll period; modern software has solved the problem for most.

Many rules have been suggested to avoid any ambiguity when writing the year in text but the best method is simply to write if out in full (1999-2002).  There have been publications with rules which differ under different circumstances but any technical need to limit the number of characters used has long gone and the simple form avoids any ambiguity.  Should the need arise of to write using the tags BD and AD, it also important to choose a style that avoids ambiguity.  AD (anno domini (Latin: in the year of the lord), refers to the birth of Jesus Christ, the year 1 AD (somewhat inaccurately but notionally) being his year of birth, and anything tagged BC (before Christ) being the years prior, counted backwards and starting at 1 BC, there being no year zero (which is a nuisance because it means not all the twentieth century consists of years numbered 19xx, the last year of the century being 2000; 1 January 2001 being the first day of the new century and millennium).  Classically, the convention in English was to place the letters BC after the year and AD before.  That was so the written word would pay tribute to the spoken, the common expression in formal and ecclesiastical use being "in the year of our Lord 2021".  That’s now rare and it may be preferable to use the suffixed (55 BC, 2021 AD) for both.  The alternatives to BC &AD are BCE (before common era) & CE (common era), the years exactly aligned and, although there seems no accepted convention about where the letters are placed, use should be consistent.

Rorschach

Rorschach (pronounced raw-shack)

(1) A canton and town in Switzerland.

(2) A personality test using ink-blots

1927: The ink-blot based personality analysis was first published in codified form in 1927, the genesis of which was a 1921 paper by Swiss psychiatrist Hermann Rorschach (1885-1922).  Rorschach (Wahlkreis) is a constituency of the canton of Saint Gallen, Switzerland and Rorschach is its largest town.  The town lies on the Swiss side of Lake Constance, the construct of the name an early form of the German Röhr (reeds) + Schachen (lakeside).

The Rorschach test was for some time a standard clinical diagnostic tool in psychology & psychiatry.  It was a collection of ten “ink blots”, five rendered in grey scale, two in grey & red and three in color, all printed on separate cards and presented to the subjects who were asked (1) What might this mean? & (2) What parts of the card made you say that?  The usual protocol was to provide a pencil and have the subject write their responses in the space underneath the image although, depending on the circumstances, a clinician might engage with the subject and obtain more of their thoughts or the tests could immediately be taken for analysis.  Fond of jargon, the profession even took the opportunity to coin a word to describe specific responses, a subject thought to be especially demonstrative in their response to a Rorschach ink blot said to be exhibiting "extratensive" tendencies.  As an adjective it was thus a synonym of "extroverted" and is occasionally seen outside of psychology where it probably adds little but confusion.  It served also as a noun, the relevant subjects being labelled "extratensives".

Lindsay Lohan in Rorschach Ink-Blot Test inspired gold beaded cocktail dress at the Source Code premiere, Crosby Street Hotel, New York City, March 2011.  The dress was paired with black patent ankle strap platform pumps shoes and matching opaque tights.

The idea of using indeterminate and ambiguous shapes as a way of assessing an individual's personality had been around for centuries before Dr Rorschach began his research and in the nineteenth century there were even popular parlor games which used the idea although they were designed to amuse rather than analyze.  What made Dr Rorschach’s work different was the sheer quantity of the data with with he worked, his research encompassing some 300 patients in mental institutions (with a control group of 100 “normal” subjects) to whom to he exposed over 400 ink-blots before selecting the ten which had proved to be of the greatest diagnostic utility.  Although the method was not greatly different from the games, the Rorschach test was genuinely scientific in its design and the systematic approach linking impressionistic responses to ambiguous shapes, this producing evidence of certain tendencies.  Within the still embryonic psychiatric profession, his approach was thought novel and initially received little support.  His book (a 174-page monograph Psychodiagnostik (Psychodiagnostics)), when eventually published in 1921 contained the structure of the ink-blot tests and the results of the 300 patient survey yet it attracted more interest from intrigued literary reviewers than the medical journals and he died little more than a year after its release.  Even the appearance of reviews in the odd literary magazine however did little to stimulate appeal because the book was very much a work by a scientist for other scientists and Dr Rorschach had made no attempt to make his findings accessible to a general audience.  It wasn’t until the work was republished and others began to refine the methodology that others saw potential, especially after professional mathematicians added rigor to the statistical models used to generate the scores from which conclusions were drawn.

The Rorschach cards.

However, those who inherited the work also shifted the goal posts.  While Dr Rorschach had always intended the ink-blots to be only a helpful tool in the diagnosis of schizophrenia, such was the expansion of the profession in the inter-war years that many became interested and, by 1938, the test had been adapted and was being promoted as a kind of “personality testing kit”.  It was quite a departure from Dr Rorschach’s original vision which had been designed deliberately to maintain some ambiguity in the images, his belief that the diagnosis of schizophrenia lay in the margins between the possible responses whereas when used as a personality testing tool, the answers took on the character of a parameter which, when collectively assessed with the provided statistical tool, placed patients in categories.  The test in that form proved highly successful, its proliferation assisted by the demands of wartime and the military’s need for psychological testing, the Rorschach kit easily produced, more popular with subjects than many other methods and, as a piece of mathematics, able easily to be collated into the big data sets electronic machines were beginning to make possible.  It had that those qualities the military so adore: Speed, standardization and simplicity.  It was therefore by the mid 1940s a standard part of psychological testing, used in everything from job applications to assessing an inmate’s eligibility for parole so it was perhaps inevitable it would be applied to the defendants in the Nuremberg trial (1945-1946).  Even before the International Military Tribunal (IMT; which would conduct the trial) assembled, the authorities in charge of the Nazis in custody insisted on psychiatrists and psychologists being available as soon as the prisoners had been assembled.  There were a number of reasons for this, notably that they wanted to ensure the prisoners had the support necessary to dissuade them from attempting suicide and there was the need also to ensure all were mentally competent to stand trial.  Additionally, there was genuine curiosity about the Nazis because never had there been such an opportunity to subject to tests two-dozen odd who were responsible for what was becoming clear were the greatest crimes in history.  The question then, as now was: Are “normal ordinary people” able to be drawn to commit evil acts or are some people evil.

The famous astrophotograph of The Pillars of Creation in the Eagle Nebula of the Serpens constellation (taken by the Hubble Space Telescope on 1 April 1995) imagined as four Rorschach ink-blot cards.  The original is at the top, below is a rendering in greyscale and the lower two have different filters applied.

In 2022, the JWST (James Webb Space Telescope) was used to obtain a more detailed image of what was happening there some 7000 years ago and while the consensus among cosmologists was comething like “not much has appears to have changed in 27 years”, because the JWST captures in infrared, it was able to penetrate the dense dust, revealing embedded stars and internal structures Hubble (which captured only visible light) couldn’t see.  So much more detailed was the later image that the sharper edges of the clouds could be studied, providing insights into the interplay between the gas and stellar winds.

There is significance in some Rorschach inkblot plates including color while others are black-and-white and the use of color was a deliberate design choice by Hermann Rorschach as part of the “interpretative tool-set” used to assess a subject's responses.  Of the ten plate, cards 1, 4, 5, 6 & 7 are black & white, cards 2 & 3 include red & black while cards 8, 9 & 10 feature multiple colors, including pastels.  The notion was that color introduces emotional and affective complexity and it must be remembered that in this context, “black” & “white” also are “colors”.  According to Dr Rorschach, (1) black & white blots tend to elicit more structured, form-based, and cognitive responses, (2) red is often interpreted as a prompt for more emotional, aggressive, or stimulus-bound reactions and (3) the multi-colored blots test the subject's ability to integrate complex stimuli, including emotional nuance, conflict, or ambiguity.  The theory thus was color could be used to help assess (1) emotional responses, (2) impulsivity, (3) affective regulation and (4) cognitive integration.  What all that of course implied is that were the plates to be rendered in black (and thus rely on shape alone), outcomes and the validity of the test would be affected, most obviously because of the removal of stimuli which would make responses more form-focused, diminishing the utility of the test in differentiating certain traits, notably the interpretation of ambiguous affective signals.  This has been tested and researchers reported results became less rich and less diagnostic when color was removed.

PapaLeoArts take on the Rorschach in water colors.  This array should probably be thought a montage but there might be critics who would find definitional reasons why it's a collage.

In the ink-blots, Dr Rorschach used color selectively with some plates wholly black shapes on a white background, the allocation as critical to the integrity of the process as the shapes but once the test became well known, the ink-blots became pop-culture artefacts, reproduced on posters, T-Shirts, coffee mugs and anything else which might be packaged for sale.  Sometimes the color mix was retained in the original while others applied just about everything from the motifs of psychedelia to polka-dots.     

The Rorschach tests were of course only one of the tools the clinicians assigned to Nuremberg used and the conclusion drawn was that all defendants were sane in the sense they were "legally" sane and thus mentally competent to stand trial even if they were depressed psychopaths (that seemed to be the most common phrase).  Quite what part the tests played in this isn’t clear but the test results themselves assumed a life independent of the trial because of a dispute between the two clinicians most involved in the testing and it wasn’t until the 1990s they were (almost) all published.  This psychological time capsule proved irresistibly tempting for one of the US’s foremost Rorschach experts who over the years had assembled records which could be used as an extraordinarily diverse control group which included (in the hundreds) medical students, Unitarian ministers, psychology students, criminals, business executives and random patients from private practice.  From this were selected the clerics and psychiatric outpatients, the purpose of a comparison with the Nuremberg Nazis being a critique of a recently published analysis of the test results which had concluded the defendants (as individuals and a representatives of the whole Nazi hierarchy) were “cursed beyond redemption” and thus profoundly of “the other”.  Their work was not entirely conventional by accepted scientific standards and they tacitly acknowledged some of the long acknowledged limitations of the test but never wavered from their finding “…the Nazis were not psychologically normal or healthy individuals”.

Defendants in the dock, Palace of Justice, Nuremberg, 1945-1946.  The defendant in the front row at the far right of the photograph was Horace Greeley Hjalmar Schacht (1877–1970; president of the Reichsbank 1923-1930 & 1933-1939, general plenipotentiary for war economy 1935–1937 and Reichsminister without portfolio 1937-1943) and he secured an acquittal, which might seem surprising given the extent of his complicity in the Nazi re-armament programme but it did reflect the historic difficulties in securing the convictions of enablers of crime (accountants, lawyers, financiers etc) who are a step or more removed from the act(s) being prosecuted, a phenomenon which manifests still in many jurisdictions.  Of the accused, Dr Schacht was the only confessed Freemason but there's never been anything to suggest any of the IMT's eight judges had any connection with the cult.

The notion  “…the Nazis were not psychologically normal or healthy individuals” was as controversial a view in the 1990s as it had been fifty years earlier and if a blind test could not distinguish of the Nazi’s data from the two control groups, at least some doubt would be cast.  Accordingly, ten Rorschach experts were assembled and asked to assemble them into three groups.  All that did was identify the high, medium and low-functioning of each group but there was nothing in them which separated the Nazis.  That was interesting but what was probably definitive was that even when told the nature of the data, the experts were unable to discern any difference between the responses which would enable the Nazis to be identified.  Perhaps sadly, the Nazis may have been as ordinary as they appeared in the dock, the implication being we're all capable of evil, given the right temptation, a nod to an earlier memorable phrase spoken of them: "The banality of evil".  

As that might indicate, like many tests in psychology, the Rorschach is probably useful if its limitations are recognized and the interpretations thought valid decades ago are no longer treated as proven science.  For example there may be something which can be deduced from a subject assessing the whole image in their response which is different for one who picks just a section or who finds something different in different parts but whether there’s anything substantive in the difference between seeing moth and a butterfly may be dubious.  The test is still widely used although many have abandoned it though it’s famously a cult in Japan where it’s one of the profession’s standard tools.  Elsewhere use is mixed.  Interestingly, while the fourth edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-IV (1994) did not endorse or recommend the use of any particular projective test, it did note many were used in clinical practice but cautioned that the validity and reliability of these tests had not been firmly established, urging caution.  Neither the DSM-5 (2013) nor DSM-5-TR (2022) make any reference to the Rorschach test.

Only

Only (pronounced ohn-lee)

(1) Without others or anything further; alone; solely; exclusively.

(2) No more than; merely; just.

(3) As recently as.

(4) In the final outcome or decision.

(5) Being the single one or the relatively few of the kind.

(6) Having no sibling or (less common) no sibling of the same sex (also a noun in this context).

(7) Mere (obsolete).

(8) Single in superiority or distinction; unique; the best.

(9) But (introducing a single restriction, restraining circumstance, or the like).

(10) Except (frowned upon by some).

Pre 900: From the Middle English oonly, onli, onlych, onelich & anely, from the Old English ānlich, ānlīc & ǣnlich (like; similar; equal; unique, solitary, literally "one-like”), from the Proto-Germanic ainalīkaz (one + -ly).  It was cognate with the Old Frisian einlik, the obsolete Dutch eenlijk, the German ähnlich (similar), the Old Norse álíkr, the Old High German einlih, the Danish einlig and the Swedish enlig (unified).  Synonyms include solitary & lone in one context and peerless & exclusive in the other.  Only is a noun, adjective, adverb & conjunction, onliness, onlyer & onlier are nouns and onliest & onlest are adjectives ; the noun plural is either onlys or onlies (both rarely used).

Only’s use as an adverb (alone, no other or others than; in but one manner; for but one purpose) and a conjunction (but, except) developed in Middle English.  In English, the familiar distinction of only and alone (now usually in reference to emotional states) is unusual; in many languages the same word serves for both although Modern German has the distinction in allein/einzig.  The mid fifteenth century phrase "only-begotten" is biblical, translating Latin unigenitus and Greek monogenes; the Old English word was ancenned. The term "only child" has been in use since at least the early eighteenth century.  The derived forms were once in more frequent use than now.  Someone who only adheres to the particular thing mentioned, excluding any alternatives. Onlyism (definitely non-standard) used to be quite a thing in Christianity in matters where there were different versions of documents and among Church of England congregations (often in the same parish) some were once adamant that only a certain edition of the Book of Common Prayer was acceptable and the others represented revisionism, heresy or, worse of all, smelled of popery.  Thus there were 1549-onlyiers, 1559-onlyiers, 1562-onlyiers etc.  The same factionalism of course continues to exist in many religions (and in secular movements and institutions too) but onlier has faded from use.  The adjectives onliest & onlest (a superlative form of only used almost exclusively in the US) are now rare and onlest is used mostly in African American Vernacular English (AAVE).  

No ambiguity intended: Lindsay Lohan in sweatshirt from the I ONLY SPEAK LILOHAN range.  Lilohan is a non-geographically specific dialect of English, the name a contraction derived from that of its creator.  It appears to use a conventional US English vocabulary but is delivered, with an occasionally halting delivery, in an accent vaguely Russian or Eastern European.  Pedants would of course have preferred the text to be: "I SPEAK ONLY LILOHAN".

The construct of the Old English ānlīc being ān (one) + -līc (-ly), only is thus understood in Modern English as on(e) + -ly.  One was from the Middle English oon, on, oan & an, from the Old English ān (one), from the Proto-West Germanic ain, from the Proto-Germanic ainaz (one), from the primitive Indo-European óynos (single, one).  It was cognate with the Scots ae, ane, wan & yin (one); the North Frisian ån (one), the Saterland Frisian aan (one), the West Frisian ien (one), the Dutch een & één (one), the German Low German een; the German ein & eins (one), the Swedish en (one), the Norwegian Nynorsk ein (one), the Icelandic einn (one), the Latin ūnus (one) & Old Latin oinos and the Russian оди́н (odín); doublet of Uno.  The –ly prefix was from the Middle English -ly, -li, -lik & -lich, from the Old English -līċ, from the Proto-West Germanic -līk, from the Proto-Germanic -līkaz (having the body or form of), from līką (body) (from whence Modern German gained lich); in form, it was probably influenced by the Old Norse -ligr (-ly) and was cognate with the Dutch -lijk, the German -lich and the Swedish -lig.  It was used (1) to form adjectives from nouns, the adjectives having the sense of "behaving like, having a likeness or having a nature typical of what is denoted by the noun" and (2) to form adjectives from nouns specifying time intervals, the adjectives having the sense of "occurring at such intervals".

The different phonological development of only and one was part of the evolution of English.  One was originally pronounced in the way which endures in only, atone and alone, a use which to this day persists in various dialectal forms (good 'un, young 'un, big 'un etc), the long standard pronunciation "wun" emerging around the fourteenth century in southwest and west England.  William Tyndale (circa 1494–1536), who grew up in Gloucester, used the spelling “won” in his translations of the Bible which were first published between 1525-1526 and the form slowly spread until it was more or less universal by the mid-eighteenth century.  The later use as indefinite pronoun was influenced by the unrelated French on and Latin homo.

The bishops in England probably neither much noticed nor cared about Tyndale’s phonological choice but they certainly objected to his choice of words in translation (church became “congregation” and priest became “elder”) which appeared to threaten both the institution of the Church and the centrality to Christianity of the clerical hierarchy.  Tried for heresy in 1536, he was pronounced guilty and condemned to be burned at the stake although, for reasons not documented, he was, after a ceremonial defrocking, strangled until dead while tied to the stake, his corpse then burned.

Although transgressions are something the grammar Nazis rush to correct with more than their usual relish, the placement of “only” as a modifier matters only if putting it one place or the other would hinder clarity; there’s never been an absolute grammatical rule and, as long as the meaning is clear, it’s probably better to adopt whatever is the usual conversational style.  In his authoritative A Dictionary of Modern English Usage (1926), the not always tolerant Henry Fowler (1858–1933) cited the report of a man who "only died a week ago" and while acknowledging the error defended the use on the basis the placement represented "the order that most people have always used and still use", adding "any risk of of misunderstanding was chimerical".  Strictly speaking, although “We only fuck vegans” means a life consisting of nothing else, most would understand it as the view of one prepared to contemplate intimacy only with vegans.  The best compromise to adopt is probably that recommended for handling the split infinitive: Use the more exact “We fuck only vegans” in formal use (such as in writing) and the more natural, conversational “We only fuck vegans” otherwise.  Note that a PSA on a sign held aloft at a protest, although obviously “in writing” is not an example of formal use; it’s just part of the conversation.  Care though must be taken to avoid ambiguity, especially in writing because the intonations of speech and other visual clues are not there to assist in the conveying of meaning.  Were one to say “She only fucks vegans after midnight”, quite what is meant isn’t clear and the sentence is better rendered either as “she fucks only vegans after midnight" (ie carnivores will be accommodated only before midnight) or “she fucks vegans only after midnight” (ie vegans must wait for "the stroke of the midnight hour").  In informal English, “only” is a common sentence connector but again, this should be avoided in formal writing where “only” should be placed directly before the word or words that it modifies.

Front door of a Salvation Army store.

Like language, signs exist in context and the nuances are examples of one of the ways the famous “everything is text” works.  Tash Peterson's signs are written language but operate as speech, their form denoting "shouting".  A static sign on a door is different.  If that sign reads “SERVICE ANIMALS ONLY”, literally that means only such creatures are allowed in (ie no humans) and obviously that's not what's intended.  Also, that the text is in upper case does not imply “shouting” as it would in an e-mail or a social media post because the message remains conversational.  Traditionally the term "service animals" was limited to the “seeing eye” dogs used by the visually impaired but in some jurisdictions, there’s been a bit of mission-creep in the category with a menagerie of “support animals” now added to the lists though the dogs are still the most numerous.  It’s doubtful any humans have ever read the sign and departed disappointed, thinking themselves not wanted, but just in case, one Salvation Army store included some small print: “For the safety of our customers and team we kindly ask that all other pets are kept outside the store.”  Perhaps “For the safety of our customers and team, kindly we ask other pets are kept outside the store” would have been more elegant but Henry Fowler would have called that “linguistic pettifogging”.  Even if unnecessary in this case, clarifying small print appended to a sign on a door can be helpful but on one of Tash Peterson’s protest banners, it would be absurd.

Duplicity

Duplicity (pronounced doo-plis-i-tee or dyoo-plis-i-tee)

(1) Deceitfulness in speech or conduct, as by speaking or acting in two different ways to different people concerning the same matter; double-dealing.

(2) An act or instance of such deceitfulness.

(3) In law, the act or fact of including two or more offenses in one count, or charge, as part of an indictment, thus violating the requirement that each count contain only a single offense.

1400–1450: From the Late Middle English, from the Old French duplicite, from the Late Latin duplicitatem (nominative duplicitas (doubleness)).  Technically, the word wa borrowed from Latin duplicāre (double), present active infinitive of duplicō and the Medieval Latin duplicitās differed with ite replacing itās.  The notion is of being "double" in one's conduct ultimately is derived from the Ancient Greek diploos (treacherous, double-minded) which translates literally as "twofold, double".  Related in Medieval Latin was ambiguity, noun of quality from duplex, genitive (duplicis (two-fold)).

Duplicity good and bad

Because such conduct is inherent to human interaction, there are many words either similar in meaning or a synonym of duplicity.  Duplicity is the form of deceitfulness that leads one to give two impressions, either or both of which may be false.  Deceit is the quality that prompts intentional concealment or perversion of truth for the purpose of misleading.  The quality of guile leads to craftiness in the use of deceit; one uses guile and trickery to attain one's ends. Hypocrisy is the pretence of possessing virtuous qualities such as sincerity, goodness or devotion.  Fraud refers usually to the practice of subtle deceit or duplicity by which one may derive benefit at another's expense.  Trickery is the quality that leads to the use of tricks and habitual deception.  In modern English usage, the most common sense of duplicity is “deceitfulness.”  The roots of this meaning are in the initial dupl from the Latin duplex (twofold, or double).  We do seem a duplicitous lot.

Alexander Haig (1924–2010; US Secretary of State 1981-1982) & Ronald Reagan (1911–2004; US President 1981-1989) (left) and Lord Carrington (1919–2018; UK Foreign Secretary 1979-1982) & Margaret Thatcher (1925–2013; UK Prime Minister 1979-1990) (right).

To accuse someone duplicity is usually to allege or suggest something negative, the idea that someone has acted in a manner perhaps not dishonest but certainly misleading or dishonorable.  However there are fields of endeavor where the successfully duplicitous are often admired and the most Machiavellian can be held in awe.  In international relations, it’s true in the upper reaches of diplomacy.

Duplicity, art and science: Haig and Carrington, the White House, 26 February 1981.

More than General Colin Powell (b 1937; US Secretary of State 2001-2005) and more even than General Dwight Eisenhower (1890–1969; US President 1953-1961), General Alexander Haig (1924-2010) was an exemplar of that uniquely Washington DC creature, the political soldier, whose career shuttled between the military, diplomacy and politics.  After a meeting in 1981, Haig was heard to remark the UK Foreign Secretary, Lord Carrington, was a "duplicitous bastard".  Beyond the beltway, that would be a disparaging comment, but, in the world of international diplomacy, it’s more an expression of admiration of professional skill.
