Exposome

Exposome (pronounced eks-poh-sohm)

(1) A concept describing (1) the environmental exposures an individual encounters throughout life and (2) how these factors impact an individual's biology and health.

(2) The collection of environmental factors (stress, diet, climate, health-care etc) to which an individual is exposed and which can have an effect on health outcomes.

2005: The construct was expos(e) +‎ -ome, the word coined by cancer epidemiologist Dr Christopher Wild, then director of the International Agency for Research on Cancer (IARC).  Expose (in the sense of “to lay open to danger, attack, harm etc”; “to lay open to something specified”) dates from the mid-fifteenth century and was from the late Middle English exposen, from the Middle French exposer (to lay open, set forth), from the Latin expōnō (set forth), with contamination from poser (to lay, place). The –ome suffix was an alteration of -oma, from the Ancient Greek -ωμα (-ōma).  It was only partially cognate to -some (body), from σῶμα (soma) (body), in that both share the case ending -μα (-ma), but the ω was unrelated.  The sense was of “a mass of something” and use is familiar in forms such as genome (in genetics the complete genetic information (DNA (deoxyribonucleic acid) or RNA (ribonucleic acid)) and phenome (the whole set of phenotypic entities in a cell, tissue, organ, organisms, and species). Exposome is a noun and exposomic is an adjective; the noun plural is exposomes.

The study and assessment of external and internal factors (chemical, physical, biological, social, climatic etc) factors that may influence human health is not new and evidence of interest in the topic(s) exist in the literature of physicians and philosophers (there was sometimes overlap) from the ancient civilizations of Greece, Rome, China, Persia and India.  One of the paradoxes of modernity in medicine was that simultaneously there developed an interest in (1) interdisciplinary and holistic approaches while (2) specialization become increasingly entrenched, the latter leading sometimes to a “siloing” in research and data accumulation.  What makes exposome a useful tool is it is a way of expressing the interplay between genetics and environmental factors in the development of diseases with a particular focus on chronic conditions and widely the concept has been applied in many fields of medicine beyond public health.  What it does is calculate the cumulative effect of multiple exposures, allowing researchers to “scope-down” to specific or general gene-environment interactions, producing data to permit a more accurate assessment of disease risk and thus the identification of useful modes of intervention.

Dr Wild’s coining of exposome came about because some word or phrase was needed to describe his innovation which was the application of a systematic approach to measuring environmental exposures to what was coming to be known about the human genome; in a sense it was an exercise in cause and effect, the three components being (1) the external exposome, (2) the internal exposome and (3) the biological response.  The external exposome included factors such as air pollution, diet and socioeconomic factors as well as specific external factors like chemicals and radiation.  The internal exposome included endogenous factors, such as hormones, inflammation, oxidative stress, and gut microbiota.  The biological response described the complex interactions between the external and internal exposome factors and their influence on an individual's physiology and health.

At its most comprehensive (and complex), the exposome is a cumulative measure of all environmental exposures to which an individual has been subject throughout their entire life.  While that’s something that can be modelled for an “imagined person”, in a real-world instance it will probably always be only partially complete, not least because in some cases critical environmental exposures may not be known for long after their effect has been exerted; indeed, some may be revealed only by an autopsy (post mortem).  Conceptually however, the process can be illustrated by example and one illustrative of the approach is to contrast the factors affecting the same individual living in three different places.  What that approach does is emphasize certain obvious differences between places but variations in an exposome don’t depend on the sample being taken in locations thousands of miles apart.  For a variety of reasons, the same individual might record a radically different outcome if (in theory) living their entire life in one suburb compared with one adjacent or even in one room in one dwelling compared with another perhaps only a few feet away.  Conditions can be similar across a wide geographical spread or different despite close proximity (even between people sitting within speaking distance), the phenomenon of “micro-climates” in open-plan offices well documented.  The number of variables which can be used usefully to calculate (estimate might be a better word) an individual’s (or a group’s) exposome is probably at least in the dozens but could easily be expanded well into three figures were one to itemize influences (such as chemicals or specifics types of pollutant matter) and such is the complexity of the process that the mere existence of some factors might be detrimental to some individuals yet neutral or even beneficial to others.  At this stage, although the implications of applying AI (artificial intelligence) to the interaction of large data sets with a individual’s genetic mix have intrigued some, the exposome remains an indicative conceptual model rather than a defined process.

As an example, consider the same individual living variously in New York City, Dubai or Los Angeles.  In each of those places, some factors will be universal within the locality while others will vary according to which part of place one inhabits and even at what elevation at the same address; the physical environment in a building’s ground floor greatly can vary from that which prevails on the 44^th floor:

(1) Air Quality and Pollution: Moderate to high levels of air pollution, especially from traffic (NO₂, PM2.5). Seasonal heating (oil and gas) contributes in winter.  Subway air has unique particulate matter exposure.

(2) Climate and UV Radiation: Humid continental climate—cold winters and hot summers. Seasonal variability affects respiratory and cardiovascular stressors.

(3) Diet and Food Environment: Diverse food options—high availability of ultra-processed foods but also global cuisines. Food deserts in poorer boroughs can reduce fresh produce access.

(4) Built Environment and Urban Design: Dense, walkable, vertical urban environment. High reliance on public transport; more noise pollution and crowding stress.  Lower car ownership can reduce personal emissions exposure.

(5) Cultural and Psychosocial Stressors: High-paced lifestyle, long working hours. High density increases social stress, noise, and mental health challenges.  Diversity can be enriching or alienating, depending on context.

(6) Economic and Occupational Exposures: Highly competitive job market. Occupational exposures vary widely—white-collar vs service industries. Union protections exist in some sectors.

(7) Healthcare Access and Public Policy: Robust healthcare infrastructure, but disparities remain by borough and income. Medicaid and public hospitals provide some safety net.

(1) Air Quality and Pollution: Frequently exposed to dust storms (fine desert dust), high PM10 levels, and air conditioning pollutants. Limited greenery means less natural air filtration.  Desalination plants and industrial expansion add further exposure.

(2) Climate and UV Radiation: Extreme desert heat (45°C+), intense UV exposure, little rain. Heat stress and dehydration risks are chronic, especially for outdoor workers.

(3) Diet and Food Environment: High import dependency. Abundant processed and fast foods, especially in malls. Dietary pattern skewed toward high sugar and fat content.  Cultural fasting (eg Ramadan) introduces cyclical dietary stressors.

(4) Built Environment and Urban Design: Car-centric city. Pedestrian-unfriendly in many areas due to heat and design. Heavy air conditioning use is a major indoor exposure pathway.

(5) Cultural and Psychosocial Stressors: Strict social codes and legal restrictions influence behavioral exposures. Expat life often means social disconnection and job insecurity for migrant workers.

(6) Economic and Occupational Exposures: Large migrant workforce faces occupational health risks, including long hours in extreme heat. Labor protections are inconsistent.

(7) Healthcare Access and Public Policy: Healthcare access stratified—good for citizens and wealthy expats, less so for low-wage migrants. Private sector dominates.

(1) Air Quality and Pollution: Known for smog due to vehicle emissions and topography (valley trap). Ozone levels high, especially in summer. Wildfire smoke increasingly common.

(2) Climate and UV Radiation: Mediterranean climate with mild, dry summers. High UV exposure, though moderated by coastal influence. Drought conditions affect water quality and stress.

(3) Diet and Food Environment: Strong health-food culture, organic and plant-based diets more common. Yet fast food and food deserts remain in less affluent areas.  Hispanic and Asian dietary influences prominent.

(4) Built Environment and Urban Design: Sprawling, suburban in many parts. High car dependence means more exposure to vehicle exhaust.  Outdoor activities more common in certain demographics (eg, beach culture).

(5) Cultural and Psychosocial Stressors: Cultural emphasis on appearance, wealth, and entertainment may increase psychosocial pressure.  Homelessness crisis also creates variable community stress exposures.

(6) Economic and Occupational Exposures: Gig economy widespread, leading to precarious employment. Hollywood and tech industries also introduce unique workplace stress patterns.

(7) Healthcare Access and Public Policy: California’s public health programs are progressive, but uninsured rates still high. Proximity to cutting-edge research centers can boost care quality for some.

So one's exposome is a product of what one wants or gets from life, mapped onto a risk analysis table.  In New York City, one copes with urban pollution and persistent subway dust in an increasingly variable climate marked by periods of high humidity, a dietary range determined by one's wealth, the advantage of a good (if not always pleasant) mass transit system and the possibility of a “walking distance” lifestyle, albeit it in usually crowded, fast-paced surroundings.  Employment conditions are mixed and access to quality health care is a product of one's insurance status or wealth.

In Dubai, one lives with frequent dust storms, months of intense heat and UV exposure, a dependence on food imports, the constant temptation of fast food (FSS; fat, salt, sugar).  The car-centric lifestyle has created a built environment described as “pedestrian-hostile” and there are sometimes severe legal limits on the personal freedom especially for migrant workers who are subject to heat exposure and limited labor rights (even those which exist often not enforced).  The health system distinctly is tiered (based on wealth) and almost exclusively privatized.

The air quality in Los Angeles greatly has improved since the 1970s but climate change has resulted in the more frequent intrusion of smoke from wildfires and the prevailing UV exposure tends to be high; the climate is not as “mild” as once it was rated.  While there are pockets in which walkability is good, Los Angeles mostly is a car-dependent culture and the coverage and frequency of mass-transit has in recent decades declined.  Although this is not unique to the city, there's heightened awareness of a sensitivity to specific cultural pressures based on appearances and perceptions of lifestyle while housing stress is increasing.  Economic pressures are being exacerbated by the growth of the gig economy and traditionally secure forms of employment are being displaced by AI (bots, robots and hybrids).  Although California's healthcare system is sometimes described as "progressive", on the ground, outcomes are patchy.

So each location shapes the exposome in distinctive ways and the potential exists for the process better to be modelled so public health interventions and policies can be adjusted.  Of course, some risks are global: anywhere on the planet there’s always the chance one might be murdered by the Freemasons but some things which might seem unlikely to be affected by location turn out also to be an exposome variable. Because planet Earth is (1) roughly spherical, (2) and travels through space (where concepts like up & down don’t apply) and (3) constantly is exposed to meteoroids (every day Earth receives tons of “space dust”), it would be reasonable to assume one is equally likely to be struck by a meteoroid wherever one may be.  However, according to NASA (the US National Aeronautics and Space Administration), strikes are not equally likely everywhere, some latitudes (and regions) being more prone, due to several factors:

(1) Because Earth’s rotation and orbital motion create a bias, meteoroids tend more often to approach from the direction of Earth’s orbital motion (the “apex direction”), meaning the leading hemisphere (the side facing Earth's motion, near the dawn terminator) sees more meteoroid entries than the trailing hemisphere.  On a global scale, the effect is small but is measurable with the risk increasing as one approaches the equatorial regions where rotational velocity is greatest.

(2) Because most meteoroids approach from near the plane of the Solar System (the ecliptic plane), there’s what NASA calls a “latitude distribution bias”: Earth’s equator being tilted only some 23.5° from the ecliptic, meteoroids are more likely to intersect Earth’s atmosphere near lower latitudes (the tropical & sub-tropical zones) than near the poles.  So, those wishing to lower their risk should try to live in the Arctic or Antarctic although those suffering chronic kosmikophobia (fear of cosmic phenomena) are likely already residents.

(3) Some 70% of the Earth’s surface area being the seas and oceans, statistically, most meteoroids land in the water rather than in land so the lesson is clear: avoid living at sea.  The calculated probability is of course just math; because sparsely populated deserts accumulate meteorites better because erosion is low, a large number have been found in places like the Sahara and outback Australia but those numbers reflect a preservation bias and don’t necessarily confirm a higher strike rate.  The lesson from the statisticians is: Don’t dismiss the notion of living in a desert because of a fear of being struck by a meteoroid.

(4) Gravitational focusing, although it does increase Earth’s meteoroid capture rates (disproportionately so for objects travelling more slowly), is a global effect so there is no known locational bias.  While there is at least one documented case of a person being struck by a meteoroid, the evidence does suggest the risk is too low to be statistically significant and should thus not be factored into the calculation of one’s exposome because one is anywhere at greater risk of being murdered by the Freemasons.

Ms Ann Hodges with bruise, Alabama, September. 1952.  Painful though it would have been, she did get  her “15 minutes of fame” and eventually sold the fragment for US$25 so there was that.

In the narrow technical sense, many people have been struck by objects from space (as estimated 40+ tons of the stuff arrives every day) but most fragments are dust particles, too small to be noticed.  The only scientifically verified injury a person has suffered was an impressively large bruise a meteorite (the part of a meteoroid that survives its fiery passage through the atmosphere to land on Earth’s surface) on 10 September 1954 inflicted on Ms Ann Hodges (1920-1972) of Sylacauga, Alabama in the US.  Weighing 7.9 lb (3.6 kg), the intruder crashed through the roof of her house and bounced off a radio, striking her while enjoying a nap on the sofa.  The meteoroid was called Sylacauga and, just as appropriately, the offending meteorite was named the Hodges Fragment.  Anatomically modern humans (AMH) have been walking the planet for perhaps 300,000 years and we’ve been (more or less) behaviorally modern (BMH) for maybe a quarter of that so it’s possible many more of us have been struck,  In the absence of records, while it’s impossible to be definitive, it’s likely more have been murdered by the Freemasons that have ever been killed by stuff falling from space although, as the history of species extinction illustrates, a direct hit on someone is not a prerequisite for dire consequences.

The cosmic intruder crashed through the roof of a house on 26 June, 2025 and although there were no injuries, Fox News reported the fragment left a hole in the floor “about the size of a large cherry tomato”.  Analysis determined the rock was from the asteroid belt between Mars and Jupiter and as well as the dramatic fireball many captured on their dashcams, it would briefly have broken the sound barrier as it entered Earth’s atmosphere.  It was also very old, dating from slightly before the formation of the Solar System’s rocky inner planets (one of which is Earth) some 4.56 billion years ago and such fragments are of interest to many branches of science because they represent a small part of the “basic building blocks” of those planets and can thus assist in understanding the processes active during the Solar System’s earliest days.  Curiously (to those not trained in such things), the cosmologists explained “such a small fragment didn’t present a threat to anyone” which seems strange given its impact left a small crater in a floor, one implication being one wouldn’t wish for such a thing to hit one’s skull.  That the impact happened in Georgia, a state adjacent to Alabama where a half-century earlier the unfortunate Ms Hodges was struck, may make some add “meteorite fragments” to their list of “exposome factors south of the Mason-Dixon Line” but the sample size is too small for conclusions to be drawn and the events are mere geographic coincidences.

Mural

Mural (pronounced myoor-uhl)

(1) A large picture painted or affixed directly on a wall or ceiling.

(2) A greatly enlarged photograph attached directly to a wall.

(3) A wallpaper pattern representing a landscape or the like, often with very widely spaced repeats so as to produce the effect of a mural painting on a wall of average size; sometimes created as a trompe l'oeil (“deceives the eye”).

(4) Of, relating to, or resembling a wall.

(5) Executed on or affixed to a wall.

(6) In early astronomy, pertaining to any of several astronomical instruments that were affixed to a wall aligned on the plane of a meridian; formerly used to measure the altitude of celestial bodies.

1400–1450: From the late Middle English mural, from the Latin mūrālis (of or pertaining to a wall), the construct being mūr(us) (wall) + ālis (the Latin suffix added to a noun or numeral to form an adjective of relationship; alternative forms were āris, ēlis, īlis & ūlis).  The Latin mūrālis was from the Old Latin moiros & moerus, from the primitive Indo-European root mei (to fix; to build fences or fortifications) from which Old English picked-up mære (boundary, border, landmark) and Old Norse gained mæri (boundary, border-land).  In the historic record, the most familiar Latin form was probably munire (to fortify, protect).  The sense of "a painting on a wall" seems to have emerged as late as 1915 as a clipping of "mural-painting" (a painting executed upon the wall of a building), a term in use since at least 1850 and derived from mural in its adjectival form.

The adjective intermural (between walls) dates from the 1650s, from the Latin intermuralis (situated between walls), the construct being from inter- (between) + muralis (pertaining to a wall) from mūrus (wall).  The adjective intramural (within the walls (of a city, building etc)) dates from 1846, the construct being intra- (within) + muralis (pertaining to a wall) from mūrus (wall); it was equivalent to Late Latin intramuranus and in English, was used originally in reference to burials of the dead.  It came first to be used in relation to university matters by Columbia in 1871.  Mural is a noun, verb & adjective; muraled is a verb & adjective, muralist & muralism are nouns and muraling is a verb; the noun plural is murals.  The adjectives murallike, muralish & muralesque are non-standard and the adverb murally is unrelated, murally a term from heraldry meaning “with a mural crown” and used mostly in the technical terms “murally crowned” & “murally gorged”.  A mural crown was a crown or headpiece representing city walls or towers and was used as a military decoration in Ancient Rome and later as a symbol in European heraldry; its most common representation was as a shape recalling the alternating merlons (raised structures extending the wall) atop a castle’s turret which provided defensive positions through which archers could fire.  The style remains familiar in some of the turrets which sometimes on the more extravagant McMansions and in the chess piece properly called the rook but also referred to as a castle.

Lindsay Lohan murals in the style of street art (graffiti): In hijab (al-amira) with kebab roll by an unknown street artist, Melbourne, Australia (left), the photograph the artist took as a template (centre) and in a green theme in Welcome to Venice mural by UK-born Californian street artist Jules Muck (b 1978) (right).  While a resident of Venice Beach, Ms Lohan lived next door to former special friend, DJ Samantha Ronson (b 1977).

In multi-cultural Australia, the kebab roll has become a fixture in the fast-food scene with variations extending from vegan to pure meat, the term “kebab” something of a generic term meaning what the vendor decides it means.  Cross-culturally the kebab roll also fills a niche as the standard 3 am snack enjoyed by those leaving night clubs, a place and time at which appetites are heightened.  After midnight, many kebab rolls are sold by street vendors from mobile carts and those in the Middle East will not be surprised to learn barbaric Australians sometimes add pineapple to their roll.  The photograph of Ms Lohan in hijab was taken during a “doorstop” (an informal press conference) after her visit in October 2016 to Gaziantep (known to locals as Antep), a city in the Republic of Türkiye’s south-eastern Anatolia Region.  The purpose of the visit was to meet with Syrian refugees being housed in Gaziantep’s Nizip district and the floral hijab was a gift from one of the residents who presumably assisted with the placement because there’s an art to a well-worn al-amira.  Ms Muck’s work was a gesture to welcome Ms Lohan moving from Hollywood to Venice Beach and the use of green is a theme in many of her works.  Unfortunately, Ms Lohan’s time in Venice Beach was brief because she was compelled to return to New York City after being stalked by the Freemasons.

Probably not long after the charcoal and ochre of the first cave paintings was seen by someone other than the artist, there emerged the calling of “art critic” and while the most common fork of that well-populated profession focuses on the aesthetic, art has also long been political.  The mural of course has much scope to be controversial because they tend to be (1) big and (2) installed in public spaces, both aspects making the things highly visible.  Unlike a conventionally sized painting which, even if large, a curator can hang in some obscure spot or put into storage, the mural is just where it is and often part of the built environment; there it will be seen.  In art history, few murals have more intriguing tales than Michelangelo’s (Michelangelo di Lodovico Buonarroti Simoni; 1475–1564) ceiling and frescos (1508-1512) in the Vatican’s Sistine Chapel but although there were at the time of the commissioning and completion few theological or political squabbles, there were the Vatican’s usual personal and institutional tensions, cardinals and bishops with their own agendas (some financial) peeking and poking into why Julius II (1443–1513; pope 1503-1513) had handed the juicy contract to someone thought primarily a sculptor rather than a painter.

Sistine Chapel, The Vatican, Rome.

The political stoush came later.  At the time, the nudity had been noted and while some voices were raised in opposition, there was no attempt to censor the work because during the High Renaissance, depictions of nudity (on canvas, in marble etc) were all around including in the Vatican but decades later, during the sittings of the Council of Trent (1545–1563), critiques of “nakedness” in art became more vocal.  That was especially the case after the Counter-Reformation (circa 1550–circa 1670) produced a more severe Church, a development with many repercussions, one of which was the “fig-leaf campaign” in which an artist was commissioned to paint over (especially male) genitalia, the traditional “fig leaf” the preferred device.  Perhaps curiously, despite the early appearance of the motif in the art of Christendom, for centuries the fig leaf wasn’t “obligatory” although they appear often enough that at times they must have been at least “desirable” and in other periods and places clearly “essential”.  The later infamous “Fig Leaf Campaign” was initiated by Pope Paul IV (1476–1559; pope 1555-1559) and continued by his successors although it was most associated with the ruling against “lasciviousness” in religious art made in 1563 by the Council of Trent.  It was something very much in the spirit of the Counter-Reformation and it was Pius IV (1499–1565; pope 1559-1565) who commissioned artist Daniele da Volterra (circa 1509–1566) to paint over the genitalia Michelangelo had depicted on his ceiling, extending his repertoire from strategically positioned leaves to artfully placed draperies or loincloths; Romans to his dying day nicknamed Volterra “Il Braghettone” (the breeches maker).  As late as the nineteenth century Greco-Roman statues from antiquity were still having their genitals covered with fig leaves (sometimes detachable, a trick the British Museum later adopted to protect Victoria’s (1819–1901; Queen of the UK 1837-1901) delicate sensibilities during her infrequent visits).  Another example of practical criticism was the edict by Pius IX (1792–1878; pope 1846-1878) that extant male genitalia on some of the classical statues adorning the Vatican should be “modified” and that involved stonemasons, sculptors and other artisans receiving commissions to “modify or cover” as required, some fig leaves at the time added.  It is however a myth popes sometimes would be seen atop a ladder, chisel in hand, hammering away for not only did they hire "the trades" to do their dirty work, what was done was almost always concealment rather than vandalism.

Then a work in progress, this is one of the few known photographs of Diego Rivera's mural in New York City's Rockefeller Center.  According to the Workers Age of 15 June, 1933, the image was "...taken surreptitiously by one of Rivera's aides..."  

Still, no pope ever ordered Michelangelo’s creation painted over but not all artists were so fortunate.  On 9 May 1933 (by coincidence a day when the Nazis publicly were burning books), New York’s very rich Rockefeller family ordered Mexican artist Diego Rivera (1886-1957) to cease work on his mural depicting "human intelligence in control of the forces of nature", then being painted in the great hall of the 70-storey Rockefeller Center in New York City.  Taking photographs of the mural was also prohibited.  What incurred the family’s wrath was the artist's addition of a depiction of Bolshevik revolutionary comrade Vladimir Lenin (1870–1924; head of government of Russia or Soviet Union 1917-1924) against a background of crowds of unemployed workers.  Comrade Lenin had not appeared in the conceptual sketch (entitled Man at the Crossroads Looking with Hope and High Vision to the Choosing of a New and Better Future) the artist had provided prior to the commission being granted.  Nelson Rockefeller (1908–1979; US vice president 1974-1977 and who earned immortality by having "died on the job") genuinely was a modern art fan-boy and attempted to negotiate a compromise but it was the nadir of the Great Depression, marked by plummeting industrial production, bank failures and an unemployment rate approaching 25%; other family members, knowing there was in the air talk of revolution (the Rockefeller family had much to lose), didn’t want unemployed getting ideas.  To them, Lenin was close to being the devil incarnate and "the devil makes work for idle hands".  The mural was covered by a canvas drape until February 1934 when, under cover of darkness, it was broken up and carted off to be dumped, the family dutifully having paid the artist his US$21,000 fee.

Snack

Snack (pronounced snak)

(1) A small portion of food or drink or a light meal, especially one eaten between regular meals.

(2) In the phrase “go snack”, to share profits or returns (mostly archaic).

(3) In slang, someone physically attractive and sexually desirable (regionally limited).

(4) To have a snack or light meal, especially between regular meals.

1300–1350: From the Middle English verb snacchen, snacche, snache & snak & noun snacche, snak & snakee (to snap at, bite, seize (as of dogs) and cognate with the Middle Dutch snacken (to snap (as of dogs), from snakken and a variant of snappen (to snap)) and the Norwegian dialect snaka (to snatch (as of animals)).  In many European languages, snack is used in the same sense though in Swedish technically it’s deverbal of snacka (to chat, to talk).  The pleasing recent noun snackette is either (1) A small shop or kiosk selling snacks or (2) smaller than usual snacks (the word often used by dieters to distinguish their snacks from the more indulgent choices of others).  The synonyms include morsel, refreshment, bite, eats, goodies, nibble, pickings & tidbit (often misused as "titbit").  Specific classes of snack include "halal snack" (one which would be approved by a ayatollah, mufti, mullah etc as conforming to the strictures of Islam) and kosher snack (one which would be approved by a rabbi (or other rabbinical authority) as conforming to the dietary rules in Judaism).  Snack is a noun, adjective & verb, snackability, snackette & snackery are nouns, snackable is a noun & adjective snacking & snacked are verbs and snacky, snackish & snakelike are adjectives; the noun plural is snacks.

Cadbury Snack.

The original Middle English verb (to bite or snap (as of dogs), probably came either from the Middle Dutch or Flemish snacken (to snatch, snap; chatter), the source of which is uncertain although one etymologist traces it to a hypothetical Germanic imitative root snu- used to form words relating to the snout or nose.  The sense of "having a bite to eat; a morsel or light meal” dates from 1807.  The noun snack (a snatch or snap (especially that of a dog) developed from the verb and emerged circa 1400.  The meaning extended to "a snappish remark" by the 1550s and "a share, portion, part" by the 1680s (hence the now archaic expression “go snacks” which meant "share, divide; have a share in").  The familiar modern meaning "a small dish morsel to eat hastily" was first noted in 1757.  The first snack bar (a place selling snacks) seems to have opened in 1923 and the similar (often smaller, kiosk-type operations) snackettes were a creation of US commerce in the 1940s.  Snack bars could be either stand-alone businesses or something operating within a stadium, theatre, cinema etc.  The commercial plural form "snax" was coined in 1942 for the vending machine trade and the term “snack table” has been in use since circa 1950.

Nestlé Salted Caramel Munchies.

Functionally (though not etymologically) related was munchies (food or snack) from 1959, the plural of the 1917 munchie (snack eaten to satisfy hunger) from the 1816 verb munch (to eat; to chew).  The familiar (to some) phrase “got the munchies” in the sense of "craving for food after smoking weed (marijuana)" was US stoner slang which was first documented in 1971 but Nestlé corporation’s Munchies weren’t an opportunistic attempt to grab the attention of weed smokers.  The chocolate Munchies pre-date the slang use of the word by over a decade, introduced in 1957 by the Mackintosh company, Nestlé acquiring the brand in 1988 when it acquired Rowntree Mackintosh and it’s not known if the slang use can be attributed to some stoner coming back from the shop with a bag-full of the snacks and telling his grateful and ravenous companions “I’ve got the Munchies” but it's such a good explanation it should be accepted as verified fact; etymologists who disagree have no soul.  Munchies were originally milk chocolates with a caramel and biscuit centre but the range has in recent years proliferated to include centres of mint fondant, chocolate fudge, cookie dough and salted caramel.  The latest variation has been to use a white chocolate shell; this described as a “limited-edition” but it’s presumed if demand exists, it will become a standard line.

Lindsay Lohan stocking up her snack stash, London, 2008.

This is use of the word "snack" in the most modern sense: pre-packaged items designed usually for one or for a small group to share.  Although most associated with "treats and indulgences" (chocolate bars the classic example), not all snacks can be classified as "junk food" and there's a whole sub-section of the industry dedicated to the production (and, perhaps more to the point, marketing) of "healthy snacks".  Critics however caution that unless it's simply a convenient packaging of a "whole food" (such as nuts which have been processed only to the extend of being shelled), the label should be studied because even food regarded in its natural state as a "healthy choice" can be less so when processed.  The markers to assess include the obvious (fat, salt, sugar) as well as chemicals and other additives, some with names only an industrial chemist would recognize.

Peter Dutton (b 1970; leader of the Australian Liberal Party 2022-2025) enjoying a “Dagwood Dog”, Brisbane Ekka (Exhibition), August 2022.  Because of the context (event, location, not sitting at a table, dish, time of day), this he would probably have regarded “a snack” rather than “a meal”.  The “Dagwood Dog” was a local variant of the “HotDog” or “Corn Dog” and Mr Dutton never denied being a Freemason.

A “snack” is by definition both (1) of a lesser quantity than a “meal” and (2) eaten at a different time than the meal (as conventionally defined: breakfast, lunch, dinner) but there are nuances.  For some, the infamous “midnight snack” (a late-night or early-morning trip to the bridge for those who awake with hanger pangs or who can’t sleep because they are so hungry) sometimes evolves, ad-hoc, into what others would call “a meal” while the curious “supper” can be anything from a “light snack” to a synonym for “dinner”.  Additionally, it’s variable by individual: what a Sumo wrestler calls a “snack” might well for a week feed a ballerina.  So there’s nothing which exactly defines the point at which a “snack” should properly be called a “meal” because it’s something geographically, culturally and individualistically deterministic.  A hot dog presented on a plate might be called “a meal” whereas one eaten while wandering around the Minnesota State Fair might be though “a snack”.  It’s tempting to imagine (at least in Western culture) that if utensils (knife, fork, chopsticks et al) are used it must be a meal and snacks are inherently finger food but the list of exceptions to that will be long.

Snack-shaming: A specific sub-genre of "fat-shaming", the modern convention is that when seen with shopping carts laden with processed snacks, fat people may be photographed and posted on social media, provided their identity adequately is concealed.

A snack for one can also be something like an apple or banana (the latter pre-packaged by nature with its own bio-degradable wrapping) and "snack" was used to describe such quick and easy "bites to eat" by the early eighteenth century, building on the slightly early use meaning "a quickly prepared meal" (as opposed to an elaborate dish) and the term became popular to describe meals carried by workers (the sandwich the exemplar) to eat on their break.  Prior to that "to snack" was to suggest one was having just part of the whole (such as a "slice of cake") and that use was from the traditional use of the word to mean "a portion" of just about anything (land, money, food etc).  As English evolved, the word came to be associated almost exclusively with food and the now rare slang use in the finance industry is the only survivor of earlier use.  It has though become an idiomatic form: (1) A person with an obviously high BMI (body mass index (ie looks fat)) can be "snack-shamed" if (1a) observed eating unhealthy snacks or (1b) with supermarket cart loaded with them; (2) A "snack-slut" is one who can't resist snacking and is used as a self-descriptor (socially acceptable and usually amusing if subject has low BMI); (3) A "snaccident" (a portmanteau word, the blend being snac(k) + (ac)cident)) refers to a snack eaten "by accident" and the validity of such excuses must be assessed on a case-by-case-basis (again, tends to be BMI-dependent); (4) A "snackery" is (4a) a place where one buys one's snacks or (4b) an informal term used to describe the place where dead fat people are sent (on the model of "knackery" (a slaughterhouse where animal carcasses unfit for human consumption or other purposes are rendered down to produce useful materials such as adhesives)); (5) A "snackette" is variously (5a) an especially small snack, (5b) a small outlet selling snacks (on the model of "luncheonette" (a small restaurant with a limited range of dishes)) or (5c) a (usually one-off) sexual partner about whom one has no future plans.               

Quondam

Quondam (pronounced kwon-duhm or kwon-dam)

(1) As a pronominal, former; one-time; having been formerly.

(2) As a pronominal, of an earlier time.

1580s: An adaptation of the earlier (1530-1550) from earlier use as an adverb (formerly) and noun (former holder of an office, title or position), from the Latin adverb quondam (formerly, at some time, at one time; once in a while) the construct being quom, cum (when, as), from the primitive Indo-European root kwo- (stem of relative and interrogative pronouns) + -dam (the demonstrative ending).  Quondam is an adjective, quondamship is a noun and quondamly is an adverb; the noun quondam is now archaic but can be used in the sense of “one’s ex” and if one is prolific in the generation of quondamship, the noun plural is quondams.  According to one severe critic on Urban Dictionary, “quondamness” is defined as “A thesaurus full of imaginary yet important sounding words that shoddy authors use in order to find strange obscure or even imaginary words to use in their stories, in the hopes of sounding more intelligent than they will ever be.” 

For a simple concept ("used to be"), quondam enjoys an impressive number of synonyms including former, previous, erstwhile, old, one-time, past, late, once, whilom, sometime, defunct, bygone, vanished, gone, departed, extinct and expired.  Some (extinct, expired, defunct) have specific technical meanings which limit their use while others (late, departed, gone) are most associated with the dead but otherwise quondam is available as a way of enriching a text.  In informal use, quondam has been used as a noun in the sense of one's ex-partner being “a quondam” and, as a re-purposed literary word, it has been adapted to the social media age with helpful, non-standard forms coined:

Quondam: One's ex-partner.

Quondaming: The act of dumping a partner.

Quondamed: The act of being so dumped.

Quaondamer: One who dumps a partner (in the form “serial quondamer”, applied to those who frequently dump).

Quondamee: One who has been quonadmed by a quandamer (in the form “serial quondamee”, applied to those frequently dumped).

Quondamish: An act which can be interpreted as being dumped but requires confirmation.

Quondamesque: Behavior which suggests having been dumped.

Quondamism: The study of dumped ex-partners (a branch of behaviorism).

Quondamist: A practitioner of quondamism (employed often by internet gossip sites) who can distinguish between genuine quondamees and those exhibiting quondam-like characteristics.  The experts have developed predictive models which they apply to work out who is next to be quondamed.

A quondam atheist who changed his mind: The Rage Against God: How Atheism Led Me to Faith (2010) by Peter Hitchens.

As a pronominal, writers like to use somewhat obscure quondam when drawing attention to those who were once “something” have for whatever reason become “something else”.  There are quondam atheists who became Christians including the (1) British academic & writer CS Lewis (1898–1963) who seems most to have be influenced in his conversion by JRR Tolkien (1892–1973), the US journalist Lee Strobel (b 1952) who set out to disprove Christianity after his wife converted, but the hunter ended up captured by the game, becoming a Christian, (3) the Physician-geneticist Francis Collins (b 1950) who lead the Human Genome Project and was either atheist or agnostic during his early scientific career but became affected by his encounters with expressions of faith among his patients although reading CS Lewis seems also have had a profound effect, (4) the writer Peter Hitchens (b 1951) who was a most truculent militant atheist (more so even than his brother Christopher) but returned to the faith of his youth after a period of personal reflection (which soon he’d call “soul-searching”) and witnessing “the consequences of godlessness” (although he writes for the tabloid Mail on Sunday which can’t be good for the soul), (5) the writer and broadcaster Malcolm Muggeridge (1903–1990) who as well as being quondam atheist was also quondam Marxist (a common coupling) and, like a 40-a-day smoker who has kicked the habit, having had his fun, he became a most moralistic Christian and (6) TS Eliot (1888–1965) who probably never was a quondam atheist but certainly had his moments of doubt so may qualify as an (off & on) quondam agnostic until his thirties and some of his later poetry does suggest he was keeping to a Godly path.

In political science there was a whole school of quondam communists of the “God that Failed” school, often arrayed in lists by conservatives anxious to rub in the “I told you so” moment.  The favorites though are the quondam Trotskyites (“Trots” to friend & foe alike) and while variously they’ve swung to some to conservatism, liberalism, nationalism or even God, it’s remarkable how many include the term “ex-Trotskyist” in their biodata, there being something romantic about comrade Leon Trotsky (1879-1940) and his Fourth International not shared by either comrade Stalin (1878-1953; Soviet leader 1924-1953) who ordered his murder or Karl Marx (1818-1883) although the latter should be treated sympathetically because of his many troubles including constipation (measured in days) but by far the greatest distraction must have been the painful genital boils.  In April 1867, in one of the many letters he sent to his collaborator Friedrich Engels (1820–1895), he lamented: “I shan’t bore you by explaining [the] carbuncles on my posterior and near the penis, the final traces of which are now fading but which made it extremely painful for me to adopt a sitting and hence a writing posture. I am not taking arsenic because it dulls my mind too much and I need to keep my wits about me.”

The Revolution Betrayed: What is the Soviet Union and Where is it Going? (1937) by Leon Trotsky.  Three years after publication, comrade Stalin's assassins finally tracked down comrade Trotsky and murdered him; the weapon was an ice axe.

There was the writer and eternal enfant terrible Christopher Hitchens (1949-2011), in his youth a member of the International Socialists, who drifted away gradually but perceptibly before re-shaping his world-view into Islam vs the West after the 9/11 attacks, becoming a fellow-traveller with the neo-cons.  Across the Atlantic there was Irving Kristol (1920-2009) whose time with the Young People's Socialist League seems to have been more than youthful impetuosity because his faction was the then unfashionable Trotskyist group opposed to the Soviet state being built by comrade Stalin.  The extent to which his hard-right conservative wife changed his intellectual direct can be debated but for those who like “nurture vs nature” discussions, their son William Kristol (b 1952) was born a right-winger and has never deviated.  Perhaps the most famous quondam Trotskyist & Communist (he was inconsistent in his self-identification) of the Cold War years was the quondam Soviet spy Whittaker Chambers (1901-1961) whose testimony was crucial in the trial of State Department official Alger Hiss (1904–1996), the case on which the young congressman Richard Nixon (1913-1994; US president 1969-1974) built his reputation as an anti-communist.  Nixon later became one of many quondam presidents but the only one rendered thus by having to resign in disgrace.

Lindsay Lohan's quondam list (2013), partially redacted for publication by In Touch magazine.

Because her hectic lifestyle had for a decade-odd been chronicled (accurately and not) by the tabloid press, even before In Touch magazine in 2014 published a partially redacted list of three-dozen names Lindsay Lohan had in her own hand compiled of those with whom she’d enjoyed intimacy, she already had a reputation as a serial quondammer.  The list contained 36 names which seemed a reasonable achievement for someone then 27 although it wasn’t clear whether the count of three-dozen quandams was selective or exhaustive and upon publication it produced reactions among those mentioned ranging from “no comment” to denials in the style of a Clintonesque “I did not have sex with that woman”.  Other points of interest included Ms Lohan's apparently intact short & long-term memory and her commendably neat handwriting.  She seems to favor the “first letter bigger” style in which the format is “all capitals” but the first letter of a sentence or with proper nouns such as names is larger.  In typography, the idea is derived from the “drop cap”, a centuries-old tradition in publishing where the opening letter of a sentence is many times the size of the rest, the text wrapping around the big letter.  In many cases, a drop cap was an elaborate or stylized version of the letter.  Her writing was praised as neat and effortlessly legible.  

Ms Lohan was about as pleased the list had been published as Gore Vidal (1925–2012) might have been if gifted the complete anthology (deluxe edition, leather bound with commentaries by the author) of the works of Joyce Carol Oates (b 1938).  It transpired the list of 36 was written as part of the fifth step of the Alcoholics Anonymous (AA) programme Ms Loan was in 2013 undertaking at the Betty Ford Clinic; that is known informally as the “Confession” step and it encourages members to acknowledge the harm caused to themselves and others in their pursuit of alcohol: “Admitted to God, to oneself, and to another human being the exact nature of our wrongs.”  Legally, despite being tagged “confession”, US courts have never extended to the AA the same status of privileged communication which conferred on what passes between penitent and priest in the confession box so committing one’s sins to paper is doubly dangerous.  Subsequently interviewed, Ms Lohan said she could “neither confirm or deny” the accuracy of the list but seemed to confirm what In Touch had published appeared to be a photograph of what she’d written.  That was an interesting distinction to draw but who took the photograph remains a mystery although she concluded: “Someone when I was moving must have taken a photo of it”, adding: “So that’s a really personal thing and that’s unfortunate.”  Ms Lohan’s best-known quondam remains former special friend Samantha Ronson.

There is also much quondamism among those disillusioned by the cults of which they were once devoted followers and there have been many confessed Freemasons who abandoned the pseudo-faith, denouncing it as they stormed from the temple vowing never to return.  Although the Freemasons have centuries of experience in conducting cover-ups and are suspected to have infiltrated many news organizations, the fragmentation of the media in the internet age has meant stories sometimes do hit the headlines.  In 2024, the Rev Canon Dr Joseph Morrow (b 1954) not only resigned as Grand Master of The Freemasons of Scotland but also ceased to be a Mason.  Dr Morrow’s very public exit from the cult saw a flurry of speculation about what low skulduggery might have been involved, suggestions the he had been undermined by a “traditionalist” Masonic faction opposed to his plans to “modernize the craft”.  The conservatives clearly liked things the way then were and it seems there were tensions between members, some spooked by Dr Morrow pledged to oversee reform and widen recruitment, saying: “We will expand the global presence of Scottish freemasonry by inspiring our members to enjoy their involvement and by attracting new members.  This will be achieved by cultivating a positive culture of inclusivity and a meaningful impact on our communities.”  That must have sounded ominously like a DEI (diversity, equity & inclusion) agenda, not welcome by many in the all-male institution that is Scottish-rite Masonry and hearing Dr Morrow speak of “greater transparency” would have sat not well with those who prize Masonic secrecy and opaqueness.

Quondom Grand Master & quondom Freemason Dr Joseph Morrow in his Masonic Grand Master regalia.  Note the ceremonial apron being worn underneath jacket, a style almost unique to The Ancient and Accepted Scottish Rite of Freemasonry.

Suggestions were published alleging Dr Morrow left the cult because he’d learned the traditionalist faction was plotting and scheming against him, planning to propose an alternative grand master while he was on holiday in the Far East; his departure was said to be a case of “jumping before he was pushed”.  Circling the aprons, a spokesman for the Grand Lodge (1) denied any dissident members were plotting and scheming a palace coup, (2) claimed Dr Morrow had never raised “significant concerns”, (3) asserted: “No other candidate was planning to stand against him” and (4) maintained “Dr Morrow’s decision to resign was made for his own personal reasons.”  He concluded: “We are grateful for the huge contribution he has made to Scottish Freemasonry over many years and wish him well for the future.”  Whatever really happened, following his abrupt departure, the quondom Grand Master is also a quondom Freemason.
