Adhesive

Adhesive (pronounced ad-hee-siv or ad-hee-ziv)

(1) Something coated with glue, paste, mastic, or other sticky substance (which may be intended for either temporary or permanent purposes); a substance that causes something to adhere, as glue or rubber cement.

(2) Figuratively, tenacious or clinging.

(3) Sticking fast; sticky; apt or tending to adhere; clinging.

(4) In physics, of or relating to the molecular force that exists in the area of contact between unlike bodies and that acts to unite them.

(5) The quality or degree of stickiness in the physical sense; relating to adhesion.

(6) In philately, a postage stamp with a gummed back, as distinguished from one embossed or printed on an envelope or card.

1660s: The adjective meaning “sticky, cleaving or clinging” was from the French adhésif, from the Latin adhaesivus, from adhaereō (supine adhaesum). The French construct was formed from the Latin adhaes-, past-participle stem of adhaerere (stick to), the source also of adherent.  The noun was derived from the adjective and emerged in 1881, original as a descriptor of postage stamps (as a clipping of the original (1840) adhesive stamp, the word later adopted in philately as a technical distinction between the classic stick-on stamps and other types.  Around the turn of the twentieth century, it was used in the general sense of "a substance that causes to adhere", as a point of differentiation from simple glue.  The spelling adhæsive is obsolete.

Because of the use in engineering, science, industry & commerce, adhesive is a popular modifier, the forms including adhesive capsulitis, adhesive tape, hot melt adhesive, self-adhesive, adhesive bra, adhesive bandage, adhesive binding, adhesive plaster & adhesive tape.  Words related to adhesive (in the physical or figurative sense depending on context) sense include gummy, sticky, adherent, holding, hugging, pasty, adhering, agglutinant, attaching, clinging, clingy, gelatinous, glutinous, gooey, gummed, mucilaginous, resinous, tenacious, viscid & viscous.  Adhesive is a noun & adjective, adhesion is a noun, adhesively is an adverb and adhesiveness is a noun; the noun plural is adhesives.

Very Abstract

Piet Mondrian’s (1872-1944) 1941 New York City 1 is an abstract piece created with multi-colored adhesive tape.  First exhibited at New York’s Museum of Modern Art (MOMA) in 1945 and hung since 1980 in the Düsseldorf Museum as part of the Kunstsammlung Nordrhein-Westfalen’s collection, recently it was revealed for the past 77 years it has been hanging upside down.  The work is unsigned, sometimes an indication the artist deemed it unfinished but Mondrian left no notes.

Mondrian’s 1941 New York City 1 as it (presumably correctly) sat in the artist's studio in 1944 (left) and as it was since 1945 exhibited (upside-down) in New York and Düsseldorf (right).  Spot the difference. 

The decades-long, trans-Atlantic mistake came to light during a press conference held to announce the Kunstsammlung’s new Mondrian exhibition.  During research for the show, a photograph of Mondrian’s studio taken shortly after his death showed the work oriented in the opposite direction and this is being treated as proof of the artist’s intension although experts say the placement of the adhesive tape on the unsigned painting also suggests the piece was hung upside down.  How the error occurred is unclear but when first displayed at MOMA, it may have been as simple as the packing-crate being overturned or misleading instructions being given to the staff.  However, 1941 New York City 1 will remain upside because of the condition of the adhesive strips.  “The adhesive tapes are already extremely loose and hanging by a thread,” a curator was quoted as saying, adding that if it were now to be turned-over, “…gravity would pull it into another direction.  And it’s now part of the work’s story.”

The curator made the point that as hung, the interlacing lattice of red, yellow, black and blue adhesive tapes thicken towards the bottom, suggesting a sparser skyline but that “…the thickening of the grid should be at the top, like a dark sky” and another of Mondrian’s creations in a similar vein (the oil on canvas New York City I (1942)) hangs in the Musée National d’Art Moderne in Paris with the thickening of lines at the top.  Whether Mondrian intended 1941 New York City 1 to be part of his oeuvre or it was just a mock-up in adhesive tape for the oil-on canvas composition to follow isn’t known, artists having many reasons for leaving works unsigned.

Conventional "backless" bras.

The term "backless bra" can be misleading in that most of them aren't actually built without a back-strap; rather the strap is engineered in a variety of ways to sit well below the shoulder-blades, usually somewhere around the lower back.  Often that's enough to suit the outfit with which it's being paired but sometimes there's a need to expose the whole back and here an adhesive bra can be the solution.  Adhesive bras (single-use and re-usable and sometimes called "stick-on bras" or "stickies") are specialized devices which have a large part of the surface-area facing the skin coated with a medical-grade adhesive.  Made usually from silicone or polyurethane and available in a variety of designs (in one and two-piece configurations), almost all are strapless or backless and the variations in design exist to accommodate the different clothes under which the bra will be worn.  One chooses one’s adhesive bra cognizant of the dress or top to be worn, the idea being that once dressed, only skin should be visible.  In cases where no commercial available adhesive bra is quite right, a variety of medical-grade tapes (sold as tit-tape, skin-tape, boob-tape et al) are available including double-sided versions which can hold the fabric of clothes in place.  There have the advantage of being able to rendered in whatever shape is required but can be difficult to apply single-handedly although boyfriends and girlfriends should be anxious to assist.  Experts suggest avoiding the cheapest on the market because some of there are not medical grade and there's the risk of minor skin damage and consequent infection.

For those (regardless of size) who don’t require lift and need only to minimize lateral movement, the two-piece units (which can use a central coupling depending on the outfit) are ideal because they are available in versions with a smaller surface area, some of which use a higher percentage of the adhesive material to adhere to skin below the bust-line which can be helpful.  These are essentially a modern variation of the pasties (adhesive patches worn over the nipples by exotic dancers) from the late 1950s with some structural engineering added to enhance support.

Most two-piece adhesive bras are a pair of stand-alone units but some offer the option of centre-adjustments.  The methods vary, some using Velcro, the familiar hook & eye combination or buckles but the most popular type use shoe-lace style ties.  The scope of adjustment offered is not only lateral (forcing the flesh towards the centre) but also vertical (forcing the flesh upwards), both movements enhancing cleavage and this permits the same bra to be used for more than one style of outfit.

Although mostly associated with backless and strapless styles, adhesive bras are also available which accommodate plunging necklines.  The two-piece units allow designers to display a cut to the waist but more modest renditions, optimized for cleavage, use a kind of cantilever, usually called the “plunge”.

Adhesive bras use rather than defy the laws of physics and there are limits to the volumes which can be accommodated.  As a general principle, as the movable mass (and in this case there’s not always a direct correlation between weight and volume) increases the surface area of the adhesive material which adheres to skin above the effective centre of gravity (essentially the pivot point) should increase.  That means larger sizes can be handled for backless dresses and even plunges are possible but it won’t be possible always to display the skin on the upper poles and designs required to secure a greater mass can be less comfortable because they often include some variation of an underwire to guarantee structural integrity.

Tape

Tape (pronounced teyp)

(1) A long, narrow strip of linen, cotton, or the like, used for tying garments, binding seams or carpets etc.

(2) A long, narrow strip of paper, metal etc.

(3) A strip of cloth, paper, or plastic with an adhesive surface, used for sealing, binding, or attaching items together; adhesive tape or masking tape; the trade-name “Scotch Tape” is often used as a generic descriptor.

(4) As tape measure, a flexible type of ruler, especially useful for measuring curved shapes.

(5) As finishing tape, the string stretched across the finishing line in a race and broken by the winning contestant on crossing the line; also sometimes incorrectly referred to as “finishing line” which technically is the line marked on the ground.

(6) In financial trading or news dissemination, a paper tape on which a stock ticker, news ticker or similar device would print incoming information (obsolete although the concept is still used in digital form).

(7) As magnetic tape, a usually re-usable media used to record, store and retrieve information and mounted in devices such as tape recorders, tape decks, tape arrays and tape drives, the physical tape on spools or in cassettes; in more precise forms as audio tape, data tape, videotape etc.

(8) To furnish with a tape or tapes.

(9) To tie up, bind, or attach with tape.

(10) To measure with or as if with a tape measure.

(11) To record on magnetic tape (although the phrase “to tape” is used also to refer to recording and similar activities even when no physical tape is used.

(12) As red tape, a slang term referencing bureaucratic inefficiency and delay, named after the literal red (actually often a shade of mauve) for centuries used in the British civil service to secure un-bound files.

(13) In mechanical printing, a strong flexible band rotating on pulleys for directing the sheets in a printing machine (mostly obsolete).

Pre 1000: From the Middle English tape (an unexplained variant of tappe), from the Old English tæppa & tæppe (ribbon, strip (of cloth), literally “part torn off”), akin to the Middle Low German tappen & tāpen (to grab, pull, rip, tear, snatch, pluck) and related to the Old Frisian tapia (to pull, rip, tear), the Middle High German zāfen & zāven (to pull, tear) and the Middle Dutch tapen (to tear).  The source of the Old English tæppa & tæppe is uncertain but etymologists suggest they may be back-formations from the Latin tapete (cloth, carpet).  The original short vowel became long in Middle English.  Tape & taping are nouns & verbs and taped is a verb; the noun plural is tapes.

Many other languages picked up tape or localized variations including Danish (tape), Dutch (tape), Hausa (têf), Hindi (टेप (ṭep)), Irish (téip), Japanese テープ (tēpu), Korean (테이프 (teipeu)), Norwegian (both Nynorsk & Bokmål) (tape & teip), Swahili (tepe), Swedish (tape & tejp), Thai (เทป (téep)), Tibetan (ཊེབ (ṭeb)), Turkish (teyp), Phalura (ṭeép) and Welsh (tâp) although, since tape began to be used in the context recording & storage media, the English “tape” is often used even if a local form exists in the sense of “to bind” or “a strip of fabric” etc.  The word is widely used as an element (tapeworm, magnetic-tape, tape-drive, tape-machine, tape-gun, tape-loader, tape-recorder, ticker tape, tape-measure, cassette tape et al) and there are a wide variety of adhesive tapes (electrical tape, duct tape, gaffer tape (originally gaffer's tape) sticky tape, Scotch tape & Sellotape (both registered trademarks), masking tape, packing (or packaging or parcel) tape, insulating (or insulation) tape et al), each with a slightly different specification dictated by their intended purpose or spot in the market.

Adhesive tape dates from 1885 and until the form prevailed, the product was known also as friction tape and two of the best-known, Gaffer tape and duct tape are often confused but, being designed for different purposes, are not interchangeable; distinct in construction and intended application, there can be unfortunate consequences if one is used for tasks where the other would be more appropriate.  The first tape recorders in the modern sense of a "device for recording sound on magnetic tape" were available for sale in 1932 and were then “reel-to-reel” machines, a re-use of the 1892 application describing a "device for recording data on ticker tape", that tape in the sense of "paper strip of a printer", dating from 1884.  Strangely, the verb form “tape-record” seems not to have be used prior to 1950 although the technology had for first been used in 1928; audio-tape is said to from 1957 whereas, counter-intuitively, videotape is attested as a noun from 1953 and a verb from 1958, the explanation being that tape was more widely used earlier in film & television production than in the recording industry which needed less storage space until technologies like LP (long-playing) records and stereo were adopted.  The tape-measure is attested from 1873 and the technical phrase “tape-delay” is from 1968 although the associated techniques had been in use for some time.  The disgusting tapeworm was first named in 1705, so called for its ribbon-like shape.

The phrase red tape (official bureaucratic routine or formula especially the excessive rigmarole), dates from 1736 and refers to the red tape (often also a shade of mauve), formerly used in the British civil service (and many of the colonies including the Raj) for binding up legal and other official documents, the item (requisitioned by the roll) mentioned in the civil service supply lists fist in the 1690s.  The familiar Sellotape was first sold in the UK in 1949 and is a proprietary name of a popular brand of cellulose or plastic adhesive tape.  The noun cassette, much associated with magnetic tape is from the 1793 French cassette (a little box), from a diminutive of the Old North French casse (box) and the first cassettes in the sense of "magnetic tape cartridge" is from 1960.  The ticker tape dates from 1891 and was the actual physical paper tape on which was printed the information (stock prices, news et al) and was derive from the 1883 ticker (telegraphic device for recording stock market quotations), so made because the printing was by means of impact and thus made a ticking sound when in operation.

Marilyn Monroe's dress

Kim Kardashian (b 1980) wore to the 2022 Met Gala the marquisette dress made famous by Marilyn Monroe (1926-1962) when she appeared to sing happy birthday Mr President to President Kennedy (1917-1963; US president 1961-1963) during a Democratic Party fundraiser at Madison Square Garden on 19 May 1962, ten days before the actual birthday.  Within three months, she would be dead.

It couldn’t be expected to cause quite the same stir as sixty years earlier because, cut from a sheer, silk marquisette that almost exactly matched Ms Monroe’s skin-tone, the 2500 hand-sewn rhinestones were intricately positioned to respond to the particular gait she chose for that evening and, under the limelight in the darkened amphitheater, as she moved, the crystals sparkled and the dress came alive.  It was quite a design.  In the hard, white light of the Met Gala’s red carpet, it couldn’t be expected to work the magic it did all those years ago and, not shimmering in the darkness, it seemed lifeless and perhaps it would have benefited from the contrast her lustrous natural hair would have lent but Ms Kardashian wore it well, attracting admiration (and criticism from the usual suspects) too for the reasonable achievement of shedding some 16 lbs (7¼ KG) in three weeks to ensure a comfortable fit.  Digesting the implications of that, keen-eyed fashionistas noted the vintage white coat which Ms Kardashian kept strategically positioned below the small of her back for the ritual walk to and up the staircase, some taking to Twitter to wonder if it was there to conceal that things were quite fully done-up.

The theory is plausible; it’s always been known that in 1962, Ms Monroe had to be “sewn-into” the dress just before the performance.  The day after the Met Gala, photographs circulated purporting to show Ms Kardashian with a generously sized, pear-shaped lacuna between the seams, accompanied with the accusation that the images showing things done up had been digitally modified and the haters were certainly out, one distressed soul lamenting that for Ms Kardashian to wear the dress "...was an absolute disgrace, a tacky photo opportunity" and that "...one of the most important items of clothing in history, is now tainted with the stain of the Kardashians."  There are people who do take pop-culture very seriously.  The green dress she changed into after her ascent had similar lines (and perhaps slightly more generous dimensions) but was certainly done-up and anyway, in either, she looked gorgeous.

On that night in 1962, Ms Munroe eschewed underwear but, despite the absent 16 pounds, in 2022 there was still a little more to accommodate than that for which the original structural engineering was designed to cope.  Fortunately, through long practice and extensive product development, Ms Kardashian has some expertise in invisible support, in February 2016 publishing her findings:

“I’ve used everything from duct tape to packing tape to masking tape and I think that the best I’ve found is gaffer's tape,” she said.  "It sticks the best. Make sure you don't have any lotion or oils on when you're lifting your boobs up with the tape.  Just brace yourself for when it's time to take it off, LOL."

That was of course the problem, gaffer tape intended to stick to a range of dry surfaces including timber, metal and carpet but certainly not human skin, the consequences including irritation, reddening and even losing layers of skin.  In response, Ms Kardashian developed a tape which combined the functionality of gaffer tape with the strength and durability to support the weight yet able to be removed with the effortlessness of surgical tape, leaving the skin un-damaged.  Such tapes have been sold for a while, the industry jargon being “tit tape” but the Kardashian version is claimed to be better and, significantly, available in three tones which should suit most skin colors.  Simply called “Body Tape”, it comes in rolls and can be cut to suit, preparation otherwise limited to peeling off the paper backing before applying to achieve the desired effect.  Borrowing from the concept of gaffer tape, Body Tape is reinforced with a flexible stretch cotton, designed to be not too flexible because it needs to stretch only to accommodate human movement while retaining a natural look; it must therefore exist in a “goldilocks zone”, that sweet spot between elasticity and rigidity.

On her Skims website, there’s a helpful promotional video demonstrating Body Tape being applied to a model, the commentary emphasizing it needs to be placed at an angle which will suit the clothing with which it’s to be worn and that typically will mean describing a diagonal angle which will vary according to the neckline being accommodated.  It’s a process which might be better done by two so it’s something couples can enjoy together although, with practice, presumably one would become adept at taping one’s self.  When clothed, the results were impressive though obviously results will vary according to technique and the raw material involved.  The final test was of course was the removal, the reason Body Tape was developed and, without any obvious discomfort, the model peeled off the tape.  "That wasn't painful at all", cheerfully she confirmed.

The Watergate tapes and the erased 18½ minutes

Looking over his shoulder: Richard Nixon (right) and HR Halderman (left) in the White House.

Tapes, audio and video, have played a part in many political downfalls but none is more famous than the “smoking gun” tape which compelled the resignation of Richard Nixon (1913-1994; US president 1969-1974) after it revealed he was involved in the attempt to cover-up the involvement in the Watergate break-in of some connected to his administration.  Recording conversations in the White House had been going on for years and Nixon initially had the equipment removed, the apparatus re-installed two years later after it was found there was no other way to ensure an accurate record of discussions was maintained.  Few outside a handful of the president’s inner circle knew of the tapes and they became public knowledge only in mid-1973 when, under oath before a congressional hearing, a White House official confirmed their existence.  That was the point at which Nixon should have destroyed the tapes and for the rest of his life he must sometimes have reflected that but for that mistake, his presidency might have survived because, although by then the Watergate scandal had been a destabilizing distraction, there was at that point no “smoking gun”, nothing which linked Nixon himself to any wrongdoing.  As it was, he didn’t and within days subpoenas were served on the White House demanding the tapes and that made them evidence; the moment for destruction had passed.  Nixon resisted the subpoenas, claiming executive privilege and thus ensued the tussle between the White House and Watergate affair prosecutors which would see the “Saturday Night Massacre” during which two attorneys-general were fired, the matter ultimately brought before the US Supreme Court which ruled against the president.  Finally, the subpoenaed tapes were surrendered on 5 August 1973, the “smoking gun” tape revealing Nixon HR Haldeman, 1926–1993 (White House chief of staff 1969-1973) discussing a cover-up plan and at that point, political support in the congress began to evaporate and the president was advised that impeachment was certain and even Republican senators would vote to convict.  On 8 August, Nixon announced his resignation, leaving office the next day.

Uher 5000 reel-to-reel tape recorder used by a White House secretary to create the tape (20 June 1972) with the 18½ minute gap.  (Government Exhibit #60: Records of District Courts of the United States, Record Group 21. National Archives Identifier: 595593).

To this day, mystery surrounds one tape in particular, a recording of a discussion between Nixon and Halderman on 20 June 1972, three days after the Watergate break-in.  Of obviously great interest, when reviewed, there was found to be a gap of 18½ minutes, the explanations offered of how, why or by whom the erasure was effected ranging from the humorously accidental to the darkly conspiratorial but half a century on, it remains a mystery.  Taking advantage of new data-recovery technology, the US government did in subsequent decades make several attempts to “un-delete” the gap but without success and it may be, given the nature of magnetic tape, that there is literally nothing left to find.  However, the tape is stored in a secure, climate-controlled facility in case technical means emerge and while it’s unlikely the contents would reveal anything not already known or assumed, it would be of great interest to historians.

What might be more interesting still is the identity of who it was that erased the famous 18½ minutes but that will likely never be known; after fifty years, it’s thought that were there to be any death-bed confessions, they should by now have been heard.  Some have their lists of names of those who might have "pressed the erase button" and while mostly sub-sets of Watergate's "usual suspects", one who tends not to appear is Nixon himself, the usual consensus being his well-known ineptitude in handling modern technology would rendered him a most unlikely editor though it's not impossible he ordered someone to do the deed.  However it happened, the suspects most often mentioned as having had their "finger on the button" (which may have been a foot-pedal) are Nixon's secretary and his chief of staff.  The long-serving secretary (Rose Mary Woods, 1917–2005) actually admitted to “inadvertently” erasing some 4-5 minutes of the recording by way of the “terrible mistake” of putting her foot on the “wrong pedal” while stretching to answer the desk telephone.  In explanation, she demonstrated how it happened (a reasonable piece of office gymnastics which reporters dubbed the “Rose Mary Stretch”) but always maintained there was no way she was responsible for a longer gap.  Halderman always denied any involvement in the mystery and Nixon always maintained he was shocked and disappointed when told of the silence.

Gaffer & Duct

Gaffer (pronounced gaf-er)

(1) The chief electrician on the set of a movie or television show.

(2) In informal use, a boss, supervisor, or manager.

(3) In informal use, an old man, especially one living in the country (often used affectionately or patronizingly).

(4) A foreman or overseer in charge of a group of physical laborers; the coach or manager of a sports team.

(5) In glassmaking, a master glassblower responsible for shaping glassware.

(6) Slang for boy or youth (unique to Ireland); used in maritime regions to refer to the baby of the house.

(7) A type of tape used usually as a safety device to tape-down cables to reduce the risk of tripping hazards (technically gaffer’s tape).

(8) In slang, as “to gaff”, “gaffered” or ”to gaffer”, a description of some temporary or roughly improvised repair using gaffer tape or some other quick and dirty method; “to make a gaff” as a description of a mistake is a variation of this.

1565–1575: Thought likely to be a contraction of godfather, but with the vowels influenced by grandfather.  The use to describe “an elderly rustic" was apparently based on continental analogies (compare gammer and the related French compère and German Gevatter).  It seems originally to have been a term of respect, also applied familiarly; from "old man" and was by 1841 extended to foremen and supervisors generally.  In UK police forces, it’s common slang to describe the officer in charge of a particular section or squad and in Association Football (soccer), the head coach or manager.

In the early twentieth century, it was carried over to the electrician or technician in charge of lighting on a film set because the natural lighting on early film sets was adjusted by opening and closing flaps in the tent, these cloths called gaff cloths or gaff flaps.  Because the technician used a long pole with a hook known as a “gaff hook”, he came to be known as a “the gaff hooker” and, as English does when users find there are too many syllables, this was truncated to “the gaffer”.  The tape later used for electrical cables was almost exclusively in the gaffers' toolboxes and thus became “gaffer’s tape”.  Now it’s known almost always as “gaffer tape”.

Duct (pronounced duhkt)

(1) Any tube, canal, pipe, or conduit by which a fluid, air, or other substance is conducted or conveyed.

(2) In anatomy and zoology, a tube, canal, or vessel conveying a body fluid, especially a glandular secretion or excretion.

(3) In botany, a cavity or vessel formed by elongated cells or by many cells.

(4) In the infrastructure of electricity, a single enclosed runway for conductors or cables.

(5) In a printing press, the reservoir for ink.

(6) Guidance; direction; quotation (obsolete).

1640-1650: From the Latin ductus (conveyance of water; a leading, a conduit pipe), noun use of the past participle of ducere (to lead) from dūcō (I lead, draw), from the primitive Indo-European root deuk (to lead).  Use has endured in the Medieval Latin aqueduct and the high rank of aristocracy, duke, drawn from the past participle of ducere (to lead); the construct was duc (variant stem of dūcere (to lead)) + tus (suffix of verbal action).  The meaning in an anatomical sense (vessel of an animal body by which blood, lymph etc, are conveyed) was first noted in the 1660s while that of a "conduit or channel" dates from 1713.  Use in a variety of architectural and engineering contexts to describe "tubes in a structure" developed after the use to describe an "air tube" in 1884.

Duct tape was in 1894 originally sold under the name duck tape, long, non-adhesive strips of plain cotton duck cloth used in various mechanical processes.  The name was transferred to a plastic-coated adhesive tape used by U.S. soldiers in World War II, probably because of its waterproof qualities (ie the sense of "water off a duck's back").  It continued in civilian use after the war, and the name shifted to duct tape by 1958, perhaps because the most common use was in air ducts, which also accounts for its still standard silver-gray color.

Duct and Gaffer Tape

Duct tape scene: Lindsay Lohan as Tess Conway in Freaky Friday (2003).

Often casually regarded as interchangeable, duct and gaffer tapes are constructed differently because they’re intended for different purposes.  Indeed, using one for the intended application of the other can cause messy or worse results.  They’re similar in that both are hand-tearable, conform well to uneven surfaces and tend to be sold in the same packaging and sizes.  Duct tape is constructed with a polyethylene (PE) cloth backing, a material that makes it waterproof and contains an aggressive, rubber-based glue, allowing it easily to adhere to many of surfaces.   Duct tape has (1) a shiny, reflective backing, (2) is for semi-permanent or permanent applications and (3) tends to leave an adhesive residue when removed.  A specialized variation is a heat-resistant foil (not cloth) duct tape, useful for sealing heating and cooling ducts.  For decades silvery gray, it’s now available in colors and even printed designs.

Gaffer tape is made with a coated cloth backing and a synthetic, rubber-based glue.  Because it doesn’t have the PE backing, gaffer tape is not waterproof but, the barrier properties in the backing make it moisture resistant in most cases.  This means it shouldn’t be used for waterproofing but is suitable for temporary use in high-humidity and moist environments. The adhesive on gaffer tape is less aggressive than duct tape, rendering it more easily removed when temporary need is over.  Because of its origins in the theatre, gaffer tape traditionally had a matte white or black backing to reduce the reflection of light but is now available in colored gloss finishes.

Viscous

Viscous (pronounced vis-kuhs)

(1) Of a glutinous nature or consistency; sticky; thick; adhesive; having relatively high resistance to flow; Having a thick, sticky consistency between solid and liquid.

(2) Having the property of viscosity; of or pertaining to viscosity.

1350–1400: From the Middle English, from the Middle French visqueux and the Late Latin viscōsus, the construct in Latin being visc(um) (mistletoe, birdlime (made with mistletoe berries)) + -ōsus.  The –ōsus suffix (familiar in English as –ous) was from Classical Latin from -ōnt-to-s from -o-wont-to-s, the latter form a combination of two primitive Indo-European suffixes: -went & -wont.  Related to these were -entus and the Ancient Greek -εις (-eis) and all were used to form adjectives from nouns.  In Latin, -ōsus was added to a noun to form an adjective indicating an abundance of that noun.

Viscous is a word widely used in many fields to impart the idea of stuff which (literally or figuratively) tends to stick together, usually in comparison with other stuff which in similar circumstances to some extent separates.  One of the most established instances of use is in clinical psychology where its used to refer to the behavioural tendency in patients repetitively and circumstantially to talk about a restricted range of topics, something identified as common in patients with temporal lobe epilepsy (TLE).  These patients are said also to exhibit heightened levels of social cohesion and the tendency to become "interpersonally clingy" which manifests in prolonging interpersonal encounters.  Clinicians have as a tool the Bear-Fedio self-report viscosity scale although it appears to be something which may be of most use when results are aggregated as a large data set because while one study found a laterality effect (left TLE patients exhibited greater viscosity than right TLE patients), other investigators using Bear-Fedio found no effect.  It’s thought the contradictory findings may be a result of the small (five) number of items on the scale and Bear-Fedio fails to discriminate repetitive circumstantial speech from increased social cohesion so it may be that laterality effects, when observed, are associated with one of these behaviors and not the other.

Synonyms include slimy, gooey, syrupy, adhesive, clammy, gelatinous, stiff, tenacious, thick, tough, glutinous, mucilaginous, viscid, gluey and ropy and the antonym is inviscid.  Although the comparative is more viscous and the superlative most viscous, in chemistry, engineering and physics, technical terms line extraviscous semiviscous and hyperviscous abound.  In science and engineering the derived terms include hyperviscous, pseudoviscous, elastoviscous, electroviscous, gyroviscous, isoviscous, nonviscous, semiviscous, ultraviscous, viscous damper, viscousless & viscosimeter.  Viscous, viscid, viscoid & viscoidal are adjectives, viscously is an adverb, viscousness, viscosity, viscose & viscidity are nouns.

In the physics of fluid dynamics, viscosity is the quantity expressing the magnitude of internal friction in a fluid, as measured by the force per unit area resisting uniform flow.  Many industrial lubricants have high viscosity and low viscosity lubricants typically are used in light-duty applications where lower loads (and consequently lower temperatures) are present.  Viscosity is a measure of the frictional force between adjacent layers of fluid in motion.  A fluid with no resistance is called an ideal (or inviscid) fluid but such substances exist only in controlled laboratory conditions because the second law of thermodynamics requires all fluids to have positive viscosity.  Fluids with a high viscosity, such as pitch (aka bitumen, asphalt or tar), can appear to be a solid but experiments, conducted over decades, confirm their flow.

Pre 1000: From the Middle English slime, slyme, slim & slym from the Old English slīm.  The Old English slīm may be from the Old English lim (birdlime; sticky substance) but is probably from the Proto-Germanic slīmą, from the primitive Indo-European sley- (smooth; slick; sticky; slimy), the source slao of the Old Norse slim.  The English forms were related to a remarkable number of similar words in many languages including the Dutch slijm (phlegm), the Danish slim, the Old Frisian slym, the Old Norse slīm, the German Schleim (mucus, slime), the Saterland Frisian Sliem, the Latin limus (alime, mud or mire), the Sanskrit linati (sticks, stays, adheres to; slips into, disappears), the Russian slimak (snail), the Ancient Greek λίμνη (límnē) (marsh), the Old Church Slavonic slina (spittle), the Old Irish sligim (to smear) & leinam (I follow (literally "I stick to")), the Welsh llyfn (smooth), the Greek leimax (snail), limne (marsh, pool, lake) & alinein (to anoint, besmear), the Old High German slīmen (to smooth), and the Latin līmax (snail).  The main influence on the changes in spellings noted in the Medieval period is thought to have been the Latin limus (slime, mud or mire) & linere (to daub, besmear, rub out, erase).  Slime & sliming are nouns and verbs, slimed is a verb, slimy is a noun & adjective and slimily is an adverb and slimier & slimish are adjectives; the noun plural is slimes.

Slime is available in designer colors.

Slime was used as an insult to a person from the early-fifteenth century when the phrase “to cover with slime" appeared (apparently the first use of slime as a verb) although slimeball appears not to have appeared until the twentieth and, unusually in English, hyphenation is rare.  Similar words in English include sludge, mud, goo, gunk, mucus, mire, scum, ooze, fungus & glop and, ever inventive, English has a wide range of alternatives for slimeball as an insult.  In biology, the slime-mold dates from 1880 and those with a morbid fear of slime are said to be suffering from blennophobia, from the Ancient Greek βλέννος (blénnos) (mucus, slime) + -phobia.  The suffix -phobia (fear of a specific thing; hate, dislike, or repression of a specific thing) was from the New Latin, from the Classical Latin, from the Ancient Greek -φοβία (-phobía) and was used to form nouns meaning fear of a specific thing (the idea of a hatred came later).

Slime is a popular motif in political satire, used here by Glenn McCoy (b 1965) to sum up crooked Hillary Clinton's (b 1947; US secretary of state 2009-2013) past and the 2016 presidential campaign between her and Donald Trump (b 1946; US president 2017-2021).  The use of "slime" in this context plays on the almost universal human revulsion to such substances.  

An unverified representation of the Earth’s human population as a slimeball, plonked in New York’s Central Park (a place that’s seen not a few slimeballs).  This is actually a revival of the word "slime" in the now obsolete way it was used as a disparaging reference to human flesh.  At the time it was rendered, total population was some 7.88 billion souls and the calculation used was a human density of 985 kg/m³ (2172 lb/35 cubic foot) at an average human body mass of 62 kg (137 lb).  This would create a slimeball just under 1 km (820 yards) wide but the Earth’s population may just have reached 8 billion so the slimeball’s mass will have increased by 0.010152%.

Slimeballs are where one finds them:  Crooked Hillary Clinton with Harvey Weinstein.  In some places, “slimebucket” is used to convey the same meaning.
