Pre 900: From the Middle English cluster (bunch), from the Old English cluster & clyster (cluster, bunch, branch; a number of things growing naturally together), from the Proto-Germanic klus- & klas- (to clump, lump together) + the Proto-Germanic -þrą (the instrumental suffix), related to the Low German Kluuster (cluster), the dialectal Dutch klister (cluster), the Swedish kluster (cluster) and the Icelandic klasi (cluster; bunch of grapes).  All the European forms are probably from the same root as the noun clot.  The meaning "a number of persons, animals, or things gathered in a close body" is from circa 1400, the intransitive sense, "to form or constitute a cluster," is attested from the 1540s; the use in astronomy dating from 1727.  Cluster is a noun & verb; clustery is an adjective, clustered is an adjective & verb, clustering is a noun, adjective & verb and clusteringly is an adverb; the noun plural is clusters.  The specialized technical words include the adjective intercluster (and inter-cluster) & the noun subcluster (and sub-cluster).

Clusters various

Cluster is a (slang) euphemism for clusterfuck; drawn from US military slang, it means a “bungled or confused undertaking”.  The cluster which the slang references is the cluster bomb, a canister dropped usually from an aircraft which opens to release a number of explosives over a wide area, thus the sense of something that becomes a really big mess.  Cluster bombs began widely to be used during the Second World War, the first deployed being the two-kilogram German Sprengbombe Dickwandig (SD-2) (butterfly-bomb).  The US, UK, USSR and Japan all developed such weapons, described in typical military tradition by an unmemorable alpha-numeric array of part-numbers, the battlefield slang then being "firecracker" or "popcorn" and it wasn’t until 1950 that “cluster bomb” was first used by the manufacturers and another ten years before the term came into general use.

However, the informal compound clusterfuck was at first rather more literal, emerging in 1966 meaning “orgy” or some similar event in which intimacy was enjoyed between multiple participants.  The sense of it referencing a “bungled or confused undertaking” started only in 1969, first noted among US troops in Vietnam who, with some enthusiasm, used it both as a graphic criticism of military tactics and the entire US strategy in the Far East.  The standard military euphemism is "Charlie Foxtrot”.

There are alternative etymologies for clusterfuck but neither has attracted much support, one being it was coined in the 1960s by hippie poet Ed Sanders as “Mongolian Cluster Fuck” and this may have been an invention independent of the military use.  The other is said to date from the Vietnam War and have been the creation of soldiers critical of the middle-management of the army, the majors and lieutenant colonels, those responsible for supply and logistics, aspects of war for millennia the source of many military problems.  The insignia for each of these ranks (respectively in gold or silver), is a small, round oak-leaf cluster, hence the notion when there's a screw up in the supply chain, it's a clusterfuck.  It's a good story but etymologists have doubts about the veracity.

Students learning English are taught about euphemisms and the vital part they play in social interaction.  They are of course a feature of many languages but in English some of these sanitizations must seem mysterious and lacking any obvious connection with what is being referenced.  There are also exams and students may be asked both to provide a definition of “euphemism” and an example of use and a good instance of the latter is what to do when a situation really can be described only as “a clusterfuck” or even “a fucking clusterfuck” but circumstances demand a more “polite” word.  So, students might follow the lead of Australian Federal Court Judge Michael Lee (b 1965) in Lehrmann v Network TenPty Limited [2024] FCA 369 who in his 420 page judgment declared the matter declared “an omnishambles”. The construct of that was the Latin omni(s) (all) + shambles, from the Middle English schamels (plural of schamel), from the Old English sċeamol & sċamul (bench, stool), from the Proto-West Germanic skamul & skamil (stool, bench), from the Vulgar Latin scamellum, from the Classical Latin scamillum (little bench, ridge), from scamnum (bench, ridge, breadth of a field).  In English, shambles enjoyed a number of meanings including “a scene of great disorder or ruin”, “a cluttered or disorganized mess”, “a. scene of bloodshed, carnage or devastation” or (most evocatively), “a slaughterhouse”.  As one read the judgement one could see what the judge was drawn to the word although, in the quiet of his chambers, he may have been thinking “clusterfuck”.  Helpfully, one of the Murdoch press’s legal commentators, The Australian’s Janet Albrechtsen (b 1966; by Barry Goldwater out of Ayn Rand) who had been one of the journalists most attentive to the case, told the word nerds (1) omnishambles dated from 2009 when it was coined for the BBC political satire The Thick Of It and (2) endured well enough to be named the Oxford English Dictionary’s (OED) 2021 Word of the Year.  The linguistic flourish was a hint of things to come in what was one of the more readable recent judgments.  If a student cites “omnishambles” as a euphemism for “clusterfuck”, a high mark is just about guaranteed.

Knight’s Cross of the Iron Cross with Oak leaves & Swords (1957 version).  These “de-nazified” awards were first issued by the Federal Republic of Germany (the FRG or West Germany) in 1957 and were awarded only to members of the Wehrmacht entitled to such awards.  Production of these awards ceased in 1986.

German law since the end of World War II generally have prohibited individuals from wearing the swastika but in 1957, under pressure from the newly (1955) reconstituted armed forces (the Bundeswehr (literally "Federal Defense")), the Gesetz über Titel, Orden und Ehrenzeichen (legislation concerning titles, orders and honorary signs) was amended, authorizing the replacement of Nazi-era Knight's Crosses with items with an oak leaf cluster in place of the swastika, essentially identical to the Imperial Iron Cross of 1914.

Tuft

Tuft (pronounced tuhft)

(1) A bunch or cluster of small, usually soft and flexible parts, as feathers or hairs, attached or fixed closely together at the base and loose at the upper ends.

(2) A cluster of short, fluffy threads, used to decorate cloth, as for a bedspread, robe, bath mat, or window curtain.

(3) A cluster of cut threads, used as a decorative finish attached to the tying or holding threads of mattresses, quilts, upholstery, etc.

(4) To furnish or decorate with a tuft or tufts; to arrange in a tuft or tufts.

(5) In the upholstery trade, to draw together (a cushion or the like) by passing a thread through at regular intervals, the depressions thus produced being usually ornamented with tufts or buttons.  Tufts are not merely decorative because they secure and strengthen mattresses, quilts, cushions et al; they act to hinder the movement of the stuffing.

(6) In botany, a small clump of trees or bushes.

(7) A gold tassel on the cap once worn by titled undergraduates at English universities, one of the more blatant class identifiers if the UK’s class system; the word tuft was also applied to those entitled to wear such as tassel and from this use evolved the slang "toff".

1350-1400: From the Middle English toft & tofte (bunch of soft and flexible things fixed at the base with the upper ends loose), an alteration of earlier tuffe (which endures in the Modern English tuff), from the Old French touffe, tuffe, toffe & tofe (tuft of hair (and source of the modern French touffe)), from the Late Latin tufa (a crest on a helmet (also found in Late Greek toupha) and probably of Germanic origin (the Old High German was zopf and the Old Norse was toppr (tuft, summit).  The earlier European forms were the Old English þūf (tuft), the Old Norse þúfa (mound), the Swedish tuva (tussock; grassy hillock), from the Proto-Germanic þūbǭ (tube) & þūbaz.  It was akin to the Latin tūber (hump, swelling) and the Ancient Greek τῡ́φη (tū́phē) (cattail (used to stuff beds)).  The excrescent t (as in against) was an English addition and tuft was used as a verb from the 1530s.  In some contexts, bunch, cluster, collection, cowlick, group, knot, plumage, ruff, shock, topknot & tussock can impart a similar meaning but tuft is better for its specific purpose.  Tuft is a noun and verb, tufter is a noun and tufty an adjective.  The noun plural is tufts, the present participle tufting and the past participle tufted.

The 1550s noun tuffet (little tuft) was from the Old French touffel (the diminutive suffix -et replacing the French -el) which was a diminutive of touffe.  In English the word is obsolete except for the use in the nursery rhyme Little Miss Muffet which seems to have first appeared in print in 1805 although it (and variations) may have been circulating much earlier.

Little Miss Muffet
Sat on a tuffet,
Eating her curds and whey;
There came a big spider,
Who sat down beside her
And frightened Miss Muffet away.

Little Miss Muffet in Hell.

Etymologists believe Little Miss Muffet’s tuffet was a grassy hillock or a small knoll in the ground (a variant spelling of an obsolete meaning of tuft).  The latter-day use to refer to a hassock or footstool is an example of how (usually obscure) words can acquire meanings if erroneous definitions are often repeated and come to serve some purpose.  Tuffet for example became a favorite of antique dealers who are apt to call both footstools and low seats “tuffets”, a handy practice perhaps when provenance is doubtful.

Nobleman in full dress at Cambridge (1815) with golden tuft.

The noun toff began as mid nineteenth century lower-class London slang for "a stylish dresser, a man of the smart set.  It was an alteration of tuft, which was a mid-eighteenth century English university (Oxford & Cambridge) term for students who were members of the aristocracy, a reference to the gold ornamental tassel (or tufts) worn on the academic caps (mortarboards) of undergraduates.  Throughout the “long eighteenth century” (a historian’s term which refers for the epoch running from the Glorious Revolution of 1688 to the Congress of Vienna in 1815 (the “long nineteenth” being 1815-1914 and the “long twentieth” 1914-2001 (ie 9/11))), undergraduates at both Oxford and Cambridge were differentiated into four classes: (1) noblemen, (2) gentlemen, (3) commoner-scholars (fellow-commoners at Cambridge) & (4) servitors (sometimes known at Cambridge as sizars and at Oxford as battelers).  Each of these classes of undergraduates was entitled to a different form of dress, noblemen since 1490 (further clarified in 1576) entitled to wear silk and brocaded gowns of bright colors. Such rich materials emphasized noble status, as did the costly dyes. The gowns had flap collars, Tudor bag sleeves with gold lace decorations (akin to the black lace decorations used today on Oxford gimp gowns) and a velvet round cap with a gold tassel (or tuft) was worn.  Noblemen were technically (if misleadingly) nobiles minorum gentium and included the sons of bishops, knights and baronets and, by resolution of Convocation, could include heirs of esquires.

The right to wear the golden tuft was briefly restricted to those with fathers entitled to sit in the House of Lords while those less blue-blooded were allowed only to a plain black tassel but things gradually became less exclusive until the practice was abandoned in the late nineteenth century but the transfer of sense was inevitable: wearers of golden tufts came to be known as tufts.  Those toadies or sycophants (and there were many) who were slavish followers of the tufts were tufthunters and their antics, tufthunting, such individuals and their habits quite identifiable to this day.  By the 1850s, under the influence of the cockney accent, the word had been transformed into toff (some dictionaries of slang noting toft co-existed in the 1850s but this may have been a mishearing) which endures to refer to anyone rich and powerful although the original sense was of someone apparently well-bred.

1912 Stutz Bearcat.  One of the fastest and most admired American cars of the early era, the Stutz Bearcat assumed such a place in popular culture it was (apocryphally) claimed that should anyone die at the wheel of a Stutz Bearcat, they were granted an obituary in the New York Times.

Tufted leather upholstery was common in early automobiles, the seating often exactly the same as those used in horse-drawn carriages, houses or commercial buildings.  The practice faded as production volumes increased and as early as the late 1920s was coming to be restricted to only the most expensive models.  This exclusivity tended to prevail until 1972 when Oldsmobile introduced the Regency option for its full-sized Ninety-Eight models, a package, the visual highlight of which was tufted loose-pillow velour upholstery.  Suddenly, solidly middle-class Oldsmobile (right in the middle of General Motors’ (GM) Chevrolet-Pontiac-Oldsmobile-Buick-Cadillac hierarchy) had brought both velour and loose-pillow seating to the masses.  The velour was at the time much admired and as the tufted upholstery options began to proliferate was usually offered as an alternative to leather.  In some climates the velour was probably the better choice and was welcomingly comfortable although in some of the more strident shades of red could recall the popular idea of how a bordello might be furnished.  Those who'd never enjoyed a visit to a bordello were presumably more disconcerted than regular customers.

Oldsmobile's move was as audacious and influential as Ford’s introduction in 1965 of the up-market LTD which, like the Regency package had the effect of cannibalizing sales from other divisions within the same corporation.  Cadillac, although with a range priced considerably above Oldsmobile, offered nothing with such an ostentatious interior though when it did in 1974 respond with its Talisman package, it made sure it did so with more tufted extravagance still, offering leather as well as velour.  The trend the Regency package started would last over twenty years and is remembered especially for the tufted fittings used in Imperials, Chryslers and Dodges, these said to be trimmed in Corinthian leather, an advertising agency creation which meant nothing in particular but sounded vaguely European and therefore expensive.  Not all the corporation's leather in the tufted era was described as "Corinthian" and such was the success of one advertising campaign that eventually the claim was restricted to one model range but it all came from one supplier so the label tends to be attached to all.

Conglomerate & Agglomerate

Conglomerate (pronounced kuhn-glom-er-it or kuhng-glom-er-it (noun & adjective) and kuhn-glom-uh-reyt or kuhng-glom-uh-reyt (verb))

(1) Anything composed of heterogeneous materials or elements; mass.

(2) A corporation consisting of a number of subsidiary companies or divisions in a variety of unrelated industries, usually as a result of merger or acquisition.

(3) A coarse-grained sedimentary rock consisting of round rock fragments cemented together by hardened silt, clay, calcium carbonate, or a similar material. The fragments (clasts) have a diameter of at least 2 mm (0.08 inches), vary in composition and origin, and may include pebbles, cobbles, boulders, or fossilized seashells. Conglomerates often form through the transportation and deposition of sediments by streams, alluvial fans, and glaciers.

(4) Gathered into a rounded mass; consisting of parts so gathered; clustered.

(5) Consisting of heterogeneous parts or elements.

(6) Of or relating to a corporate conglomerate.

(7) In geology, of the nature of a conglomerate.

(8) To bring together into a cohering mass.

(9) To gather into a ball or rounded mass.

1565–1575: From the Latin conglomerātus, past participle of conglomerāre (to roll-up), from glomerāre (to wind into a ball), the construct being con- + glomer- (stem of glomus) (ball of yarn or thread) + -ātus (-ate).  The prefix con- was from the Middle English con-, from the Latin con-, from the preposition cum (with), from the Old Latin com, from the Proto-Italic kom, from the primitive Indo- European ḱóm (next to, at, with, along).  It was cognate with the Proto-Germanic ga- (co-), the Proto-Slavic sъ(n) (with) and the Proto-Germanic hansō.  It was used with certain words to add a notion similar to those conveyed by with, together, or jointly or with certain words to intensify their meaning and, later, to indicate being made from or bringing together of several objects.  The suffix -ate was a word-forming element used in forming nouns from Latin words ending in -ātus, -āta, & -ātum (such as estate, primate & senate).  Those that came to English via French often began with -at, but an -e was added in the fifteenth century or later to indicate the long vowel.  It can also mark adjectives formed from Latin perfect passive participle suffixes of first conjugation verbs -ātus, -āta, & -ātum (such as desolate, moderate & separate).  Again, often they were adopted in Middle English with an –at suffix, the -e appended after circa 1400; a doublet of –ee.  Related forms include conglomeratic, conglomeritic, conglomerated, conglomerating, conglomerateur, conglomeration & conglomeratize.

Agglomerate (pronounced uh-glom-uh-reyt (adjective & noun) and uh-glom-er-it (noun))

(1) To collect or gather into a cluster or mass.

(2) Gathered together into a cluster or mass.

(3) In botany, crowded into a dense cluster, but not cohering.

(4) In geology, a mass of angular volcanic fragments united by heat; distinguished from conglomerate.

(5) In meteorology, an ice-cover of floe formed by the freezing together of various forms of ice.

1675-1685: From the Latin agglomerātus, past participle of agglomerāre, the construct being ad- (to) + -glomerāre (to wind or add into a ball), from glomus (a ball; a mass), from globus (genitive glomeris), (a ball of yarn) of uncertain origin.  Related forms are the adjective agglomerative, the nouns agglomerator & agglomeration and the verbs (used with or without object), agglomerated & agglomerating.  The intransitive sense "grow into a mass" dates from 1730.

Conglomerate rocks are those compose of mostly rounded, gravel-size clasts, a matrix of finer grained sediments, such as sand, silt or compressed clay filling the gaps between the clasts, the form held together with calcium carbonate, iron oxide, silica, or hardened clay which acts as a natural cement.

Agglomerate rocks are large, coarse fragments associated with the lava flow ejected during explosive volcanic eruptions.  Although they resemble sedimentary conglomerates, agglomerates consist almost wholly of angular or rounded lava fragments of varying size and shape. Fragments are usually poorly sorted in a matrix, or appear in a mix of volcanic dust or ash that has turned to stone.

(17) A walking beam (obsolete).

1350–1400: From the Middle English bobben (to strike in cruel jest, beat; fool, make a fool of, cheat, deceive), the meaning "move up and down with a short, jerking motion," perhaps imitative of the sound, the sense of mocking or deceiving perhaps connected to the Old French bober (mock, deride), which, again, may have an echoic origin. The sense "snatch with the mouth something hanging or floating," as in bobbing for apples (or cherries), is recorded by 1799 and the phrase “bob and weave” in boxing commentary is attested from 1928.  Bob seems first to have been used to describe the short hair-style in the 1680s, a borrowing probably of the use since the 1570s to refer to "a horse's tail cut short", that derived from the earlier bobbe (cluster (as of leaves)) dating from the mid fourteenth century and perhaps of Celtic origin and perhaps connected in some way with the baban (tassel, cluster) and the Gaelic babag.  Bob endures still in Scots English as a dialectical term for a small bunch of flowers.

The group of bob words in English is beyond obscure and mostly mysterious.  Most are surely colloquial in origin and probably at least vaguely imitative, but have long become entangled and merged in form and sense (bobby pin, bobby sox, bobsled, bobcat et al).  As a noun, it has been used over the centuries in various senses connected by the notion of "round, hanging mass," and of weights at the end of a fishing line (1610s), pendulum (1752) or plumb-line (1832).  As a description of the hair style, although dating from the 1680s, it entered popular use only in the 1920s when use spiked.  As a slang word for “shilling” (the modern 10c coin), it’s recorded from 1789 but no connection has ever been found.  In certain countries, among older generations, the term in this sense endures in phrases like “two bob watch” to suggest something of low quality and dubious reliability.

UK Prime Minister Lord Salisbury (Robert Arthur Talbot Gascoyne-Cecil, 1830–1903; UK Prime Minister for thirteen years variously 1885-1902 (prime-minister since "God knows when" in Churchill's words)).

The phrase "Bob's your uncle" is said often to have its origin in the nepotism allegedly extended by Lord Salisbury to his favorite nephew Arthur Balfour (1848–1930; UK Prime Minister 1902-1905), unexpectedly promoted to a number of big jobs during the 1880s.  The story has never convinced etymologists but it certainly impressed the Greeks who made up a big part of Australia's post-war immigration programme, "Spiro is your uncle" in those years often heard in Sydney and Melbourne to denote nepotism among their communities there.

The other potential source is the Scottish music hall, the first known instance in in a Dundee newspaper in 1924 reviewing a musical revue called Bob's Your Uncle.  The phrase however wasn't noted as part of the vernacular until 1937, six years after the release of the song written by JP Long, "Follow your uncle Bob" which alluded to the nepotistic in the lyrics:

Bob's your uncle

Follow your Uncle Bob

He knows what to do

He'll look after you

Partridge's Dictionary of Slang and Unconventional English (1937) notes the phrase but dates it to the 1890s though without attribution and it attained no currency in print until the post-war years.  Although it's impossible to be definitive, the musical connection does seem more convincing, the connection with Lord Salisbury probably retrospective.  It could however have even earlier origins, an old use noted in the Canting Dictionary (1725) in an entry reporting "Bob ... signifies Safety, ... as, It's all Bob, ie All is safe, the Bet is secured."

Of hair

A bob cut or bob is a short to shoulder-length haircut for women.  Historically, in the west, it’s regarded as a twentieth-century style although evidence of it exists in the art of antiquity and even some prehistoric cave-paintings hint it may go way back, hardly surprising given the functionality.  In 1922, the Times of London, never much in favor of anything new, ran a piece by its fashion editor predicting the demise of the fad, suggesting it was already passé (fashion editors adore the word passé).  Certainly, bobs were less popular by the 1930s but in the 1960s, a variety of social and economic forces saw a resurgence which has never faded and the twenty-first century association with the Karen hasn't lessened demand (although the A-line variant, now known in the industry as the "speak to the manager" seems now avoided) and the connection with the Karen is the second time the bob has assumed some socio-political meaning; when flaunted by the proto-feminists of the 1920s, it was regarded as a sign of radicalism.  The popularity in the 1920s affected the millinery trades too as it was the small cloche which fitted tightly on the bobbed head which became the hat of choice.  Manufacturer of milliner's materials, hair-nets and hair-pins all suffered depressed demand, the fate too of the corset makers, victims of an earlier social change and one which would in the post-war years devastate the industries supporting the production of hats for men.

Variations on a theme of bob, Marama Corlett (b 1984) and Lindsay Lohan, Sick Note, June 2017.

Hairdressers have number of terms for the variations.  The motifs can in some cases be mixed and even within styles, lengths can vary, a classic short bob stopping somewhere between the tips of the ears and well above the shoulders, a long bob extending from there to just above the shoulders; although the term is often used, the concept of the medium bob really makes no sense and there are just fractional variations of short and long, everything happening at the margins.  So, a bob starts with the fringe and ends being cut in a straight line; length can vary but the industry considers shoulder-length a separate style and the point at which bobs stop and something else begins.  Descriptions like curly and ringlet bobs refer more to the hair than the style but do hint at one caveat, not all styles suit all hair types, a caution which extends also to face shapes.

Asymmetrical Bob: Another general term which describes a bob cut with different lengths left and right; can look good but cannot (or should not) be applied to all styles.   

A-line bob: A classic bob which uses slightly longer strands in front, framing the face and, usually, curling under the chin; stylists caution this doesn’t suit all face shapes.

Buzz-cut bob: Known also as the undercut (pixie) bob, and often seen as an asymmetric, this is kind of an extreme inverted mullet; the the usual length(s) in the front and close-cropped at the back.  It can be a dramatic look but really doesn’t suit those above a certain BMI or age.

Chin-length bob: Cut straight to the chin, with or without bangs but, if the latter is chosen, it’s higher maintenance, needing more frequent trims to retain the sharpness on which it depends.  Depending on the face shape, it works best with or without fringe.

Inverted bob: A variation on the A-line which uses graduated layers at the back, the perimeter curved rather than cut straight. Known also as the graduated bob, to look best, the number of layers chosen should be dictated by the thickness of growth.

Shaggy bob: A deliberately messy bob of any style, neatness depreciated with strategic cutting either with scissors or razor, a styling trick best done by experts otherwise it can look merely un-kept.  The un-kept thing can be a thing if that’s what one wants but, like dying with gray or silver, it's really suitable only for the very young.  Some call this the choppy and it’s known in the vernacular of hairdressing as the JBF (just been fucked).

Spiky bob: This differs from a JBF in that it’s more obviously stylised.  It can differ in extent but with some types of hair is very high maintenance, demanding daily application of product to retain the directions in which the strands have to travel.    

Shingle bob: A cut tapered very short in the back, exposing the hairline at the neck with the sides shaped into a single curl, the tip of which sits at a chosen point on each cheek.  This needs to be perfectly symmetrical or it looks like a mistake.

Shoulder-length bob: A blunt bob that reaches the shoulders and has very few layers; with some hair it can even be done with all strands the same length.  Inherently, this is symmetrical.

Speak to the manager bob: Not wishing to lose those customers actually named Karen, the industry shorthand for the edgy (and stereotypically in some strain of blonde) bob didn’t become “Karen”.  The classic SttM is an asymmetric blonde variation of the A-line with a long, side-swept fringe contrasted with a short, spiky cut at the back and emblematic of the style are the “tiger stripes”, created by the chunky unblended highlights.  It's now unfashionable though still seen.

Synecdoche

Synecdoche (pronounced si-nek-duh-kee)

In the study of rhetoric, a figure of speech in which a part is used for the whole or the whole for a part, the special for the general or the general for the special; a member of the figurative language set, a group which includes metaphors, similes and personification; it describes using part of a whole to represent the whole.

Late 1400s: As a "figure of speech in which a part is taken for the whole or vice versa," synecdoche is a late fifteenth century correction of the late fourteenth century synodoches, from the Medieval Latin synodoche, an alteration of the Late Latin synecdochē, from the Ancient Greek συνεκδοχή (sunekdokhḗ) (the putting of a whole for a part; an understanding one with another (and literally "a receiving together or jointly" (ekdokhē the root of interpretation)) from synekdekhesthai (supply a thought or word; take with something else, join in receiving).  The construct was syn- (with) + ek (out) + dekhesthai (to receive), related to dokein (seem good) from the primitive Indo-European root dek- (to take, accept).  The construct of the Greek form was σύν (sún) (with) + ἐκ (ek) (out of) + δέχεσθαι (dékhesthai) (to accept), this final element related to δοκέω (dokéō) (to think, suppose, seem).  The alternative spellings syndoche & synechdoche are rare.  Synecdoche, synecdochization & synecdochy are nouns, synecdochic & synecdochical are adjectives, synecdochize is a verb and synecdochically is an adverb; the noun plural is synecdoches.  

Synecdoche vs. Metonymy

It’s one of those places in English where rules or descriptions overlap and it's easy to confuse synecdoche and metonymy because they both use a word or phrase to represent something else (and there are authorities which classify synecdoche as merely a type of metonymy although this appals the more fastidious).  Technically, while a synecdoche takes an element of a word or phrase and uses it to refer to the whole, a metonymy replaces the word or phrase entirely with a related concept.  Synecdoche and metonymy have much in common and there are grey areas: synecdoche refers to parts and wholes of a thing, metonymy to a related term. The intent of synecdoche is usually either (1) to deviate from a literal term in order to spice up everyday language or (2) a form of verbal shorthand.  In the discipline of structural linguistics, it's noted the distinction is between using a part to represent the whole (pars pro toto, from the Latin, the construct being pars (part) + prō (for) + tōtō, the ablative singular of tōtus (whole, entire)) or using the whole to represent a part (totum pro parte , from the Latin, the construct being tōtum (whole) + prō (for) + parte, the ablative singular of pars (part)).

The Pentagon, Arlington County, Virginia, USA.  Advances in technology have made the site vulnerable to long-range attacks as early as the 1950s and many critical parts of the military's administration are now located elsewhere.  After construction ended in 1943, for some 80 years the Pentagon was (in terms of floor area) the world's largest office building.  It's place on this architectural pecking order has since been supplanted by the Surat Diamond Bourse in Gujarat, India, opened in 2023.

Forms of Synecdoche

(1) A part to represent a whole: The word "head" can refer to counting cattle or people; hands for people on a specific job or members of a crew etc.

(2) A whole to represent a part: The word "Pentagon", while literally a very big building, often refers to the few decision-making generals who comprise the Joint Chiefs of Staff or more generally, the senior ranks of the US military.  However, the use of "the White House" (a smaller building) operates synecdochically to refer to "the administration" rather than "the president" and while it should be reasonable to assume some interchangeably, under both Donald Trump (b 1946; US president 2017-2021 and Joe Biden (b 1942; US president since 2021), it's been not uncommon to hear "the White House" being quoted "clarifying" (ie correcting" something said by the president .    

(3) A synecdoche may use a word or phrase as a class to express more or less than the word or phrase actually means: The USA is often referred to as “America” although this is a term from geography while "USA" is from political geography.  The word "crown" is often used to refer to a monarch or the monarchy as a whole but in some systems (notably the UK and Commonwealth nations which retain the UK's monarch as their head of state) the term "The Crown" is a synecdoche for "executive government".  

(4) Material representing an object: Cutlery and flatware is often (and often erroneously) referred to as "silver" or "silverware" even though there may not be a silver content in the metal although, "silver" being also a term referencing a color, the use is thought acceptable.

(5) A single (acceptable) word to suggest to the listener or reader another (unacceptable) word; commonly used as a linguistic work-around of NSFW (not suitable for work) rules on corporate eMail or other systems: “crock” or “cluster” are examples, pointing respectively to “crock of shit” and “cluster-fuck”.
