Stiletto

Stiletto (pronounced sti-let-oh)

(1) A small, slender knife or dagger-like weapon intended for stabbing; usually thick in proportion to its width.

(2) An archaic name for the rapier.

(3) A pointed instrument for making eyelet holes in needlework; a sharply pointed tool used to make holes in leather; also called an awl.

(4) A very high heel on a woman's shoe, tapering to a very narrow tip, also called the spike heel or stiletto heel.

(5) A beard trimmed to a pointed form.

(6) A style used in the fashioning of decorative fingernails.

1605–1615: From the Italian stiletto, a doublet of stylet, the construct being stil(o) (dagger or needle (from the Latin stilus (stake, pens))) + -etto (-ette) and from the Latin stilus came also stelo, an inherited doublet.  The etto- suffix was used to forms nouns from nouns, denoting a diminutive.  It was from the Late Latin -ittum, accusative singular of –ittus, and was the alterative suffix used to form melioratives, diminutives, and hypocoristics and existed variously in English & French as -et, in Italian as Italian -etto and in Portuguese & Spanish as -ito.  With an animate noun, -etto references as male, the coordinate female suffix being -etta, which is also used with inanimate nouns ending in -a.  It should not be confused with the homophonous suffix -eto.  Stilus was from the primitive Indo-European (s)teyg- (related to instīgō & instigare) and was cognate with the Ancient Greek στίζω (stízō) (to mark with a pointed instrument) and the Proto-Germanic stikaną (to stick, to stab).  Despite the similarity, there’s no relationship with the Ancient Greek στῦλος (stûlos) (a pillar).

A quasi-technical adoption in law-enforcement and judicial reports were the verb-forms stilettoed & stilettoing, referring to a stabbing or killing with a stiletto-like blade.  It was a popular description used by police when documenting the stabbing by wives of husbands or boyfriends with scissors or kitchen knives; use faded in the mid-twentieth century.  The idea of a long, slender beard trimmed into a pointed form being "a stiletto" popular in the sixteenth & seventeenth centuries but all such forms seem now to be referred to either as "a goatee" or "a Van Dyke".  The adjectival use can also sometimes need to be understood in the context of the phrase or sentence: "a stilettoed foot" can be either "the foot of someone wearing a shoe with a stiletto heel" or "a foot which has been stabbed with a long, thin blade.  Stiletto & stilettoing are nouns & verbs, stilettoed is a verb & adjective and stilettolike (also stiletto-like) is an adjective; the noun plural is either stilettos or stilettoes.

Of blades and heels

The stiletto design for small bladed weapons pre-dates not only modern metallurgy but antiquity itself.  The essence, a short, relatively thick blade, was technologically deterministic rather than aesthetic, most metals of the time not being as sturdy as those which came later.  Daggers were for millennia an essential weapon for personal protection but, particularly after developments in ballistics; they tended to evolve more for formal or ceremonial purposes.

The Schutzstaffel (SS) dagger model M1933 (often abbreviated to M33).

The M1933 was the standard issue to all SS members, the hilt either silver or nickel-plate while the grip was black wood.  Produced in large numbers, collectors are most attracted to the low-volume variations such as those without the manufacturer’s trade-mark or RZM control markings.  Most prized are the rare handful with a complete "Ernst Röhm inscription" which read In herzlicher freundschaft, Ernst Röhm (In heartfelt friendship, Ernst Röhm).  Given his his habits, enjoying Röhm's "friendship" would for a few have proved a double-edged sword.   Some 136,000 of the engraved SA daggers were produced, a further 9900-odd distributed to the SS.  After Röhm (1887–1934; chief of the Nazi Sturmabteilung (the stormtroopers (the SA)) was executed during the Nacht der langen Messer (Night of the Long Knives), also called Unternehmen Kolbri (Operation Hummingbird) in 1934, all holders of the Röhm Honour Dagger were ordered to have the inscription removed and most complied, the unmodified survivors thus highly collectable although in some countries, the very idea of trading Nazi memorabilia is becoming controversial.  As ceremonial devices, bladed weapons were a feature of the uniforms worn during the Third Reich (1933-1945) and they were issued to all branches of the Wehrmacht (the German armed forces) the police, the various paramilitaries, the diplomatic service as well as organizations as diverse as the railways, the fire services, the forestry service and the postal office.  In this they were continuing a long German tradition but the Nazis vision of a homogenous, obedient population included the notion that uniforms should be worn wherever possible and there is something in the cliché that (at least at the time), no German was ever as happy as when they were in uniform.

Although the term is used widely, in the narrow technical sense, not all slim, high heels are stilettos.  The classic stilettos were the extremely slender Italian originals produced between the 1930s and 1960s, the heels of which were no more than 5 mm (0.2 inch) in diameter for much of their length, flaring at the top only to the extent structurally required successfully to attach to the sole; the construction of solid steel or an alloy.  Many modern, mass-produced shoes sold as "stilettos" are made with a heel cast in a rigid plastic with an internal metal tube for reinforcement, a design not having the structural integrity to sustain the true stiletto shape.  However, English is democratic and in the context of footwear, "stiletto" now describes the visual style, regardless of the materials.

The lines of the classic black stiletto (top left) were long ago made perfect and can't be improved upon; such is the allure that many women are prepared to endure inconvenience, instability, discomfort and actual pain just to wear them.  They appeal too to designers and the style, the quintessential feminine footwear, has been mashed-up with sneakers, Crocs, work-boots, sandals and even a scuba-diver's flippers (though they really were at home only on the catwalk).  Military camouflage is often seen, designers attracted by the ultimate juxtaposition of fashion and function.  The Giuseppe Zanotti Harmony Sandals (bottom row, second from right) were worn by Lindsay Lohan on The Masked Singer (2019).    

In the world of fingernail fashioning, there are stilettos and stilettos square.  A statement shape, something of a triumph of style over functionally, the stiletto gains its dramatic effect from long and slender lines and can be shaped with either fully-tapered or partially square sides.  They’re vulnerable to damage, breaking when subjected to even slight impacts and almost never possible with natural growth and realistically, pointed nails, certainly in their more extreme iterations (the stilettos, lipstick, mountain peaks, edges, arrow-heads, claws or talons), are more for short-term effect than anything permanent.  Best used with acrylics, the knife-like style can be a danger to the nail itself and any nearby skin or stockings.  Those contemplating intimacy with a women packing these should first ponder the implications.  True obsessives insist the stiletto styles should be worn only with matching heels and then only if the colors exactly match.

1964 Hillman Imp.

The Hillman Imp was a small economy car introduced in 1964.  It was the product of the Rootes Group which needed an entry in a market segment which had been re-defined by the British Motor Corporation’s (BMC) Mini and although similar in size, the engineering was radically different: rather than the Mini's front-engine / front wheel drive (FWD) arrangement which became (and to this day remains) the template for the industry, the Imp was configured with a rear-engine and rear wheel drive (RWD), something which had for decades been a feature of small Europeans cars but was in the throes of being abandoned.  It never achieved the commercial success of the BMC product although it continued in production after 1967 when the Rootes group was absorbed by Chrysler and, perhaps remarkably, it remained on the books until 1976.  In that time, it sold in not even 10% of the volume achieved by the Mini between 1959-2000.

Hillman Imp V8, Oran Park, Sydney, Australia, 1971.

The Hillman Imp did enjoy some success in competition, winning three successive British Saloon Car Championships between 1970-1972 (competing in Class A (under 1000 cm³)) but years earlier, its light-weight and diminutive dimensions had appealed to Australian earth-moving contractor Harry Lefoe (1936-2000) who had a spare 302 cubic inch (4.9 litre) Ford (Windsor) V8 sitting in his workshop.  By then, the Imp was a Chrysler product but because the published guidelines of the Australian Sports Sedan Association (ASSA) restricted engines to those from cars built by the manufacturer of the body-shell, the small-block Ford V8 could be put in an Imp because it had been used in the earlier Sunbeam Tiger.  So the big lump of an iron V8 replaced the Imp's 875 cm³ (53 cubic inch) aluminium four and such was the difference in size that Lefoe insisted his Imp had become "mid-engined" although it seems not to have imparted the handling characteristics associated with the configuration, the stubby hybrid infamous for its tendency to travel sideways.  It was never especially successful but it was loud, fast, spectacular and always a crowd favourite.

1967 Sunbeam Stiletto.

Introduced in 1967, the Sunbeam Stiletto was a “badge-engineered” variant of the Imp (there were also Singers), the name an allusion to the larger Sunbeam Rapier (a stiletto a short blade, a rapier longer).  Badge engineering (a speciality of the British industry during the post-war years) was attractive for corporations because while it might increase unit production costs by 5-10%, the retail price could be up to 40% higher.  Very much a “parts-bin special” (although there was the odd unique touch such as the quad-headlamps and the much-admired dashboard), mostly it was a mash-up, the fastback bodywork already seen on the Imp Californian and some interior fittings and the more powerful twin carburettor engine shared with the Singer Chamois.  Curiously, some sites report the fastback lines proved less aerodynamically efficient than the Imp’s more upright original, the opposite of what was found by Ford in the US when the “formal roof” Galaxies proved too slow on the NASCAR ovals, a “semi-fastback” at essentially the same angle as the Stiletto proving the solution; the physics of aerodynamics can be counter-intuitive.  Stiletto production ceased in 1972 with the Sunbeam brand-name retired in 1976 although Chrysler used it as a model name until 1981.

Dagger

Dagger (pronounced dag-er)

(1) A short, double-edged weapon with a pointed blade and a handle, used historically for personal protection in close combat (although some were weighted for throwing), but since the development of side-arms, increasing only for ceremonial purposes (many produced without sharpened edges).

(2) In typography a mark (†) used to indicate a cross reference, especially a footnote (also called obelisk).  The double dagger (‡) is also used.

(3) In sport and military strategy, a offence which thrusts deep into opposition territory on a short front.

(4) In glaciology, the long, conical ice-formations formed from drops of water (al la the stalactites in caves).

(5) In the slang of clinical medicine, anything that causes pain like a stabbing injury (typically, some sort of barb)

(6) In basketball & American football, a point scored near the end of the game (clutch time) to take or increase the scorer's team lead.

(7) In nautical architecture, as daggerboard, a retractable centre-board that slides out to act as a keel; a timber placed diagonally in a ship's frame.

(8) To stab with a dagger or similar bladed weapon (archaic).

(9) In typography, to mark with a dagger (obelisk).

1380s: From the Middle English daggere, daggare & dagard, probably an adaptation from the thirteenth century Old French dague (dagger), from the Old Provençal or Italian daga of obscure origin but related to the Occitan, Italian & Spanish daga, the Dutch dagge, the German Degen, the Middle Low German dagge (knife's point), the Old Norse daggarðr, the Danish daggert, the Faroese daggari, the Welsh dager & dagr, the Breton dac and the Albanian thikë (a knife, dagger) & thek (to stab, to pierce with a sharp object).  Etymologists have speculated on the source of dagger, some suggesting a Celtic origin.  Others prefer the unattested Vulgar Latin daca & dacian (knife) (the name from the Roman province), from the Classical Latin adjective dācus while an entry in an eighteenth century French dictionary held the French dague was from the German dagge & dagen (although not attested until much later).  More speculatively still is the notion of some link with the Old Armenian դակու (daku) (adze, axe), an alternative to which is some connection with the primitive Indo-European dāg-u-, suggesting something cognate with the Ancient Greek θήγω (thḗgō) (to sharpen, whet).  Dagger is a noun & verb, daggering is a noun & verb, daggerman & daggerpoint are nouns, daggerlike is an adjective and daggered is a verb; the noun plural is daggers.

The association of the dagger with knightly weaponry can be traced back to French writings in the twelfth century while the other Middle Latin forms included daga, dagga, dagha, dagger, daggerius, daggerium, dagarium, dagarius & diga (the words with the -r- being late fourteenth century adoptions of the English word.  The Oxford English Dictionary (OED) lists an English verb dag (to stab) from which dagger as a verb could be derived but the verb is attested only from the turn of the fifteenth century.  Long used as a weapon of personal protection, skilled sixteenth & seventeenth century swordsmen would use one in their other (usually left) hand to parry thrusts from the opponent's rapier.  It was a high-risk technique.  The use in texts as a reference mark (also called the obelisk) dates from 1706.  The wonderfully named “bollock dagger” was a dagger with a distinctively shaped shaft having two oval swellings at the guard resembling the male testes.  The polite term was “kidney dagger”.  An “ear dagger” was used in the late medieval period and gained the name from its distinctive, ear-shaped pommel.  In slang, to be “stabbed with a Bridport dagger” was to be executed by hanging, the origin of that being the district of Bridport in Dorset being a major producer of the hemp fibre used in the production of the ropes used by hangmen.  In idiomatic use, to “look daggers at” is to stare at someone angrily or threateningly, something one would do if “at daggers drawn” (in a state of open hostility) with them.

Lindsay Lohan in stiletto heels, February 2009.  Whether much would have changed in the fashion business if the style of heel had come to be known as "dagger" instead of "stiletto" is unlikely.

Other names for the short bladed weapon included stiletto & poniard.  Stiletto was from the Italian stiletto; doublet of stylet, the construct being stil(o) (dagger or needle (from the Latin stilus (stake, pens))) + -etto (-ette).  From the Latin stilus came also stelo, an inherited doublet.  Stilus was from the primitive Indo-European (s)teyg- (related to instīgō & instigare) and was cognate with the Ancient Greek στίζω (stízō) (to mark with a pointed instrument) and the Proto-Germanic stikaną (to stick, to stab).  Despite the similarity, there’s no relationship with the Ancient Greek στῦλος (stûlos) (a pillar).  The -etto suffix was from the Late Latin -ittum, accusative singular of –ittus and was an alternative suffix used to form melioratives, diminutives and hypocoristics.  The noun plural is either stilettos or stilettoes and stilettolike (appearing also as stiletto-like) is an adjective.  A technical adoption in law-enforcement and judicial reports were the verb-forms stilettoed & stilettoing, referring to a stabbing or killing with a stiletto-like blade.  It was a popular description used by police when documenting the stabbing by wives of husbands or boyfriends with scissors or kitchen knives; use faded in the early twentieth century.  The use of “stiletto heel” to describe the elegant, narrow high heel in women's shoes dates from as recently as 1953.  Poniard (a dagger or other short, stabbing weapon) dates from the 1580s and was from the early sixteenth century French poinard, from the Old French poignal (dagger (literally “anything grasped with the fist”)), from poing (fist), from the Latin pungus (a fist (a pugio being “a dagger”)), from a suffixed form of the primitive Indo-European root peuk- (to prick).  It’s thought it was probably altered in French by association with poindre (to stab).  It was used a verb from the turn of the seventeenth century in the sense of “to stab with or as if with a poniard”.

Hermann Göring (1893–1946; leading Nazi 1922-1945, Hitler's designated successor & Reichsmarschall 1940-1945) in Luftwaffe Field Marshal’s uniform with baton and sword (1938, left) and in Luftwaffe General’s uniform with ceremonial dagger (right).  The baton would be replaced with an even more extravagant, jewel-encrusted creation when in 1940 he was appointed Reichsmarschall and it's now on display in the US Army's West Point Museum at Highland Falls, New York.  Convicted of war crimes and crimes against humanity, Göring was hanged in 1946. 

The dagger shown (right) is a standard 1935 issue for Luftwaffe officers.  Updated in 1937 and fashioned always with a 260 mm (10¼ inch) blade, the pommel and crossguard were aluminum, bearing the swastika (occasionally finished in anodized gold) on the pommel face with a Luftwaffe flighted eagle and swastika on the crossguard.  The grips were celluloid over a word base and in various production runs they were finished in colors ranging from pure white to a deep orange.  The scabbards were all in anodized grayish blue steel with a striped decoration on the body face with an oak leaf pattern on the face of the drag.  Worn suspended from straps bearing twin silver stripes on a dark grayish blue background with square buckles, it featured a short aluminum cord knot.  In an example of the expanding list of recipients entitled to wear a dagger, after 1940, authorization was extended to non-commissioned officers though without the portepee (the sword-knot which denoted an officer’s right to bear a sword).  The sword word by Göring (left) was a bespoke one-off manufactured by the Eickhorm company to mark his wedding on 10 April 1935.  The pommel was engraved with a facsimile of the Pour Le Merite (the “Blue Max”) Göring was awarded during his service as a pilot with the Jagdgeschwader 1 (better remembered as Manfred von Richthofen’s Flying Circus).

Germans have long adored uniforms and especially prized are the accessories, among the most distinctive of which are ceremonial daggers.  During the Third Reich, a period in which many institutions of state were increasingly re-ordered along military lines, the issuing of ceremonial daggers was at its most widespread and in addition to the expected recipients in the army, navy & air force, the SS, the SA, the Hitler Youth, the diplomatic service and the police, they were also part of the uniforms of organizations such as the fire department, the postal & telegraph service, the forest service, the labor service, the customs service the railway & waterways protective service and the miners association.  While it’s true that in Germany daggers had in the past been issued even to civilians, under the Nazis the scale and scope proliferated.

Masonic daggers.

Among their many mysterious rituals, the Freemasons also have their own lines of daggers which they claim are purely “ceremonial” but because all that they do is so shrouded in secrecy, the true nature of their purpose isn’t known.  It is however believed that the styles of daggers conferred reflect the grades and offices which evolved from the medieval craft guilds and presumably, the more exalted one’s place in the Masonic hierarchy, the more elaborate the dagger to which one is entitled.  Top of the pile in a Masonic Lodge is the Worshipful Master, other intriguing titles including Senior Warden, Junior Warden, Chaplain, Senior Deacon, Junior Deacon, Steward, Tyler, Mentor and Almoner.  Whether all get their own daggers or some share with others are among the many mysteries of Freemasonry.  Of the even more opaque Secret Society of the Les Clefs d’Or, nothing is known about whether their rituals include the use of daggers, ceremonial or otherwise.

Squoval

Squoval (pronounced sqwoh-vuhl)

(1) In cosmetology, a description applied mostly to describe the shape of certain fingernails and faces; essentially an oblong (a rectangle with partially ovoid shorter sides).

(2) In commerce, a trademark of the bicycle company Cervélo, describing the cross sectional shape of the downtube used in frame construction.

1984: A portmanteau word, sq(uare)- + oval.  Square was from the Middle English square, sqware & squyre from the Old French esquarre & esquerre, (which survives in modern French as équerre), from the Vulgar Latin exquadra, derived from the Latin quadro, from quadrus (square), from quattuor (four).  Oval was from the Late Latin ovalis, from ovum (egg); it was cognate with the French and Italian ovale and the Dutch ovaal.  Used both as noun and adjective, coinage is credited to Paula Gilmore, a noted manicurist (nail technician) and owner of Tips Nail Salon in San Mateo, California.  Squoval is a noun & verb, squovaled & squovaled are verbs and squovallike is an adjective; the noun plural is squovals.

Art of the fingernail

A pleasing creation, sqoval is misleading because it’s used to reference a shape which is actually a rectangle with the shorter sides defined by curves which tend to the semi-circular.  In geometry, such a shape is called a stadium, discorectangle or an obround.  It’s not to be confused with a square with rounded corners which, despite frequent use, is neither a "quartic" nor a "sqound".  A quartic is “an algebraic equation or function of the fourth degree or a curve describing such an equation or function” and sqound (a portmanteau word, the construct being sq(uare) + (r)ound is the ultimate niche word, the only known use by collectors of C4 Chevrolet Corvettes (1984-1996) describing the shift in 1990 from round to "square with rounded corners" taillights.  Mathematicians insist the correct word for a "square with rounded corners" is "squircle" (in algebraic geometry "a closed quartic curve having properties intermediate between those of a square and a circle").  The construct of squircle is squ(are) +c(ircle).  Few etymologists (and certainly no lexicographers) appear to have listed sqound as a "real" word but it's of interest because it's a rare example of a word where a "q" is not followed by a "u"; such constructs do exist but usually in the cases where initialisms have become acronyms such as Qantas (Queensland and Northern Territory Aerial Services).  Such words do appear in English language texts but they tend to be foreign borrowings including (1) qat (or khat) (a plant native to East Africa and the Arabian Peninsula, often chewed for its stimulant effects, (2) qi (a term from Chinese philosophy referring to life force or energy), qibla (the direction Muslims face when praying, towards the Kaaba in Mecca and (4) qiviut (the soft under-wool of the musk-ox, valued when making warm clothing).  

Squoval is thus a commercial descriptor in the fingernail business rather than a precise geometric description.  The basic rectangle metaphor is important in fingernail shaping because manicurists borrow from art and architecture the golden ratio which suggests humans find most aesthetically pleasing, shapes with an aspect ratio of about 1.6:1 which, coincidentally, is the relationship between a kilometre and a mile.  Nails can be shaped beyond the nominally perfect 1.6:1 but tend either to be thought exaggerated or created purely for artistic display, often to create a large surface for designs.  Manicurists, certainly in the Instagram age, are an imaginative profession and there’s been a proliferation of terms to describe species.  However, within the fingernail family, there are eight basic genera, practitioners inventing or classifying species as they emerge.  To date, the lipstick is the only widely-used form which is asymmetric.

The classic oval is said to be a symmetrical ellipse where the curve of the tip exactly mirrors the curve of the cuticle but, in real-world conditions, the former usually only tends to the latter.  The shape is natural, flattering and adaptable to both long and short nails.

Long coffins.

A natural coffin demands long nails with the fragility that implies.  The nail needs to be sufficiently long so both sides can be filed to a tapered point something like a stiletto before the tip is squared-off.  Because of that, they’re often constructed with acrylics.  Coffin in this context is actually a modern appropriation to describe what was historically known as the ballerina, a descriptor some European fashion houses still prefer but the Instagram generation has moved on and like coffin.  Coffins are rare worn in the elongated form.

Square nails provide a shape which is less susceptible to damage than many but doesn’t suit all shapes.  It’s best adopted by those with a narrow nail bed because the flat tip creates an optical illusion of additional width, making nails appear wider than they are.  Rarely seen variations include the cut out (a twin-peaked effect), the lipstick (uniquely, with an asymmetric tip) and the trapeze or flare (where the metaphor is the bell-bottom trouser leg).

A statement shape, something of a triumph of style over functionally, the stiletto gains its dramatic effect from long and slender lines and can be shaped with either fully-tapered or partially square sides.  They’re vulnerable to damage, breaking when subjected to even slight impacts and almost never possible with natural growth.  True obsessives insist they should be worn only with stiletto heels and then only if the colors exactly match.

Squovals in Dior 999.

With straight sides and a curved top, the squoval, while not as dramatic as a coffin, is good, functional engineering because its softer edges are less prone to snagging and tearing than those of a square and break less the more more delicate almonds.  Technically, the squoval is just a species of the square but its popularity meant it came to be classified as its own genus.

Usually very long, the almond has an elongated shape and a tapered tip.  Even when applied to nails with a narrow bed, they’re inherently weak at the tip so most are constructed from acrylics.  It’s a style which attracts many variations on the theme, often tending to a truer emulation of the nut at which point some should probably be classified as pointed.

Realistically, pointed nails, certainly in their more extreme iterations (sometimes called mountain peaks, edges, arrow-heads, claws or talons), are more for short-term effect than anything permanent.  Best used with acrylics, the knife-like style can be a danger to the nail itself and any nearby skin or stockings.  Those contemplating intimacy with a women packing these should first ponder the implications.

Lindsay Lohan with rounds, 2006

Rounds are less a style than a detailing of the natural human shape.  Usually worn short and simple and rarely needing an acrylic overlay, it’s a classic look with the added benefit of durability and low maintenance.

Heel & Heal

Heal (pronounced heel)

(1) To make healthy, whole, or sound; restore to health; free from ailment.

(2) To bring to an end or conclusion, as conflicts between people or groups, usually with the strong implication of restoring former amity; settle; reconcile.

(3) To free from evil; cleanse; purify:

Pre 900: From the Middle English helen, from the Old English hǣlan (cure; save; make whole, sound and well), from the Proto-Germanic hailijaną (to heal, make whole, save) from which Old Saxon picked up helian and Gothic gained ga-hailjan (to heal, cure), the literal translation of which was "to make whole", all of these from the primitive Indo-European koyl (safe; unharmed).  It was cognate with the Dutch helen, the Saterland Frisian heila, heilen & hela, the Danish hele, the Swedish hela, the Old High German heilen, the Old Norse heila, the Scots hale & hail and the Gothic hailjan, all derivative of hāl & hale (whole).  The Modern English health, healthy, healthily etc were later derivations.  Heal is a noun & verb, healing is a noun & verb and healed is a verb; the noun plural is heals.

Heel (pronounced heel)

(1) The back part of the human foot, below and behind the ankle.

(2) An analogous part in other vertebrates.

(3) In zoology, either hind foot or hoof of some animals, as the horse.

(11) The crook in the head of a golf club.

(12) In railroad construction, the end of a frog farthest from a switch.

(13) In horticulture, the base of any part, as of a cutting or tuber, that is removed from a plant for use in the propagation of that plant.

(15) In cock-fighting, to arm (a gamecock) with spurs.

(16) In admiralty jargon, the inclined position from the vertical when a vessel is at ten (or more) degrees of list.

Pre 850: From the Middle English helden, a variant of the earlier heeld and derived from the Old English hēla, heald & hieldan (to lean or slope).  It was cognate with the Dutch hiel, the Old Frisian hêl, the Old Norse hallr and the Old High German helden (to bow).  In the sense of “back of the foot”, root is the Old English hela, from the Proto-Germanic hanhilon which was cognate with the Old Norse hæll, the Old Frisian hel and the Dutch hiel), all derived from the primitive Indo-European kenk (heel, bend of the knee).  The meaning "back of a shoe or boot" is circa 1400 and features in a number or English phrases: Down at heel (1732) refers to heels of boots or shoes worn down when the owner was too poor to have them repaired; the Achilles' heel refers to only vulnerable spot in the figure from Greek mythology; in Middle English, fighten with heles (to fight with (one's) heels) meant "to run away."  The idiomatic phrase "he's a heel" began in professional wrestling, where it was used to describe a villainous character who breaks the rules, cheats, and generally behaves in an unethical manner to gain an advantage (sometimes as part of the script).  In modern use, "he's a heel" has be repurposed to disparage unsatisfactory dates, boyfriends & husbands.  The nautical, Admiralty and architectural forms are all derived (however remotely) from the earlier meanings related to slopes and angles.  Heeled & heeling are nouns & verbs, heelful is a noun and heeling is a verb & adjective; the noun plural is heels.

Heels in the military

United States Army Class A (Dress A) Uniform guide (women).

Heels in the shoes of women’s military uniforms are not unusual and the US Army guide is typical, specifying between ½ - 3 inch height on a closed-toe pump, essentially anything between a flat and a kitten heel.  With the formal dress uniforms worn for dinners and such, higher heels have long been worn.  In Western militaries, heels have never been worn with combat uniforms or when drill-marching although they’re not an unusual sight on parade grounds, worn with dress uniforms.  They have however in recent years been seen on female soldiers in both the DPRK (North Korean) and Russian armies although there seems to be no evidence of the practice during the Warsaw Pact era.

Democratic People's Republic of Korea (DPRK; North Korea): female soldiers.

Like his father (Kim Jong-il (1941–2011; The DPRK's Dear Leader, 1994-2011) and grandfather, (Kim Il-sung (1912-1994; The DPRK's Great Leader, 1948-1994), Kim Jong-un (b 1983; The DPRK's Supreme Leader (originally The Great Successor) since 2011) likes women in heels (note the big hats, a long tradition in the DPRK armed forces although the structural similarity to the Jewish Shtreimel is mere coincidence).  Because the whole DPRK military seems to be run by someone in the vein of General Scheisskopf (in German, literally "shit-head", the character in Joseph Heller's (1923-1999) Catch-22 (1961) who was obsessed with marching), the heels really are functional and better than combat boots.

Democratic People's Republic of Korea (DPRK; North Korea): female soldiers marching.

The use of any sort of heel (or conventional shoe) may seem a strange choice for military use but there's never been much to suggest it's footwear designed for the battlefield.  Actually, there are a number of analysts who maintain the whole DPRK military is not intended for actual deployment under battlefield conditions, especially in any conflict likely to extend beyond the few weeks their logistical support is thought capable of remaining effective.  However, as a well-drilled mass-formation able to march in public ceremonies, the DPRK's soldiers excel and the state's choreographed events have no match in the world, something emphasised by the cinematography, packaged quickly into slick productions for distribution to international news services.  For these purposes, women in heels works well because boots are heavy and some of the steps (including a few with some "wardrobe malfunction" potential) the women are required to perform for long duration marches would be impossible for some if they had to wear combat boots.

Russian female soldiers.

Women in the Russian military appear to use a variety of heel heights with dress uniforms including even stilettos which is interesting.  Presumably  the stilettos are used only when marching on smooth, regular surfaces; it would be very difficult to march on the cobble stones in Moscow's Red Square while in stilettos and traction & stability fragile at the margins.  That's of great significance when marching in formation because it works on the basis of "as strong as the weakest link in the chain" in that if one soldier in the line stumbles, it can trigger a chain reaction, disrupting the entire show.   

The Ukrainian minister for defense trying not to notice some stilettos.

The decision of the Ukraine's Ministry of Defense to train female soldiers to march in high heels attracted interest, much of it from Ukrainian politicians, little of it supportive, except for that expressed by female legislators.  Despite that, when in late June 2021 photographs emerged of women soldiers training in heels for a march scheduled for 24 August to mark the thirtieth anniversary of independence from the Soviet Union, an army spokesman reported the drilling to master the steps was "progressing well" although one soldier in an interview confirmed it was "...a little harder than in boots".  Social media soon went into action, one on-line petition demanding Ukraine's (male) defense minister don the not infrequently uncomfortable shoes to try marching in them and most critics (most volubly the female parliamentarians), accused the military of sexism and having a “medieval” mind-set.  The virtual protest was the next day brought into parliament when some of  his female colleagues arranged a line of high-heeled shoes before the defense minister and suggested he wear them to the anniversary parade, a joint statement from three cabinet ministers adding that the "...purpose of any military parade is to demonstrate the military ability of the army. There should be no room for stereotypes and sexism”.

The Defense Ministry initially declined to comment but did later issue as statement pointing out heels had been part of dress uniform regulations since 2017 and included pictures of female soldiers in the US military wearing heels during formal events and although they didn't mention it, Ukrainian soldiers regardless of gender all wear boots when deployed for combat or active training.  The great heel furor however didn't subside and the defense minister, after consultation with female military cadets, issued a joint statement with the military high command acknowledging the heels were inconvenient.  Later addressing a gathering of cadets, the minister pledged to look into the matter of “improved, ergonomic” footwear “in the shortest possible time”, although it wasn't made clear if the new shoes would be available for the August parade.  In another supportive gesture he also confirmed senior defense officials "would look into" improving the quality of women's underwear, this presumably in response to concerns raised by the cadets although the minister didn't go into detail of this, saying only that if the trial of the cadet's “experimental” footwear went well, they could be issued to all female members in the military.

Harder than it looks.

In recent years, women have played increasingly prominent roles in the Ukrainian military, especially in the ongoing conflict with pro-Russian separatists in eastern Ukraine, Kyiv allowing women to serve in combat units after Russia annexed the Crimean Peninsula in 2014.  Women now make up more than 15 percent of the country’s armed forces, a rate which has more than doubled since the conflict erupted and more than 13,000 women have been granted combatant status.  Some 57,000 women serve in the Ukrainian military and NATO standards are in the process of being introduced, membership of the alliance being described still as a "long term" goal.  Given Ukraine's long and often not untroubled relationship with both Russia and the Soviet Union, the lure of NATO is understandable but the Kremlin is opposed and there's now little enthusiasm in Western capitals.  The view from NATO HQ has for some time been that the relationship with Moscow will be easier to manage if a border which the Kremlin regards as hostile is not extended.

Pre-dating even the apparently abortive sartorial innovations of the Ukrainian Army, military camouflage has long attracted designers who like the juxtaposition of fashion and function (the fetching stiletto (bottom right) with the rakishly slanted heel is a Prada Camo Green Pump).  Although the purpose may not be overt, physics make the stiletto heel something of a weapon, even a 45 kg (100 lb) woman, at the point of the heel's impact, exerting a pressure 20 times that of the foot of a 2½ tonne (6000 lb) elephant.  Over the years, dance floors, the timber decks of cruise ships and many other surfaces have suffered damage.

Undeniably stiletto heels are attractive and, if worn by a skilled user, can lend a woman her most alluring posture but they can be uncomfortable, especially of worn for an extended duration, over long distances or on hard surfaces.  One solution (although it seems to unlikely to be adaptable to the most elevated of the breed) is a shoe with a "clamshell" design, a half-sole hinged from the instep, allowing the heel to use a folding mechanism so it can be transformed into a something like a ballet flat (ballet pump in some markets).  Greatly they will be valued by those who, after a long evening, have to walk a few blocks to find a taxi.
