1530-1540: From the Middle English rubben, possibly from the Low German rubben & rubbeling or the Saterland Frisian rubben.  The alternative etymology suggests it’s of North Germanic origin, a form such as the Swedish rubba (to move, scrub), all from the Proto-Germanic reufaną (to tear).  It was cognate with the Saterland Frisian rubje (to rub, scrape), the Low German rubben (to rub), the Low German rubblig (rough, uneven), the Dutch robben and rubben (to rub smooth; scrape; scrub), the Danish rubbe (to rub, scrub) and the Icelandic & Norwegian rubba (to scrape).  An agent-noun from the verb rub, the construct is rub + -er.  The –er suffix is from the Middle English –er & -ere, from the Old English -ere, from the Proto-Germanic -ārijaz, thought usually to have been borrowed from the Latin -ārius.  It was reinforced by the synonymous but unrelated Old French –or & -eor (the Anglo-Norman variant -our), from the Latin -(ā)tor, from the primitive Indo-European -tōr.

Burning rubber.  1970 Plymouth Hemi Superbird, a replica of the race cars used in NASCAR’s Grand National series that year.  One of these won the 1970 Daytona 500 but the sanctioning body changed the rules for 1971, limiting the engine capacity for cars with the wild aerodynamic modifications to 305 cubic inches (5.0 litres) while allowing others to continue to use the full 430 cubic inches (7.0 litres).

The meaning "elastic substance from tropical plants" (short for India rubber) was first recorded in 1788, having been introduced into Europe 1744 by French scientist Charles Marie de La Condamine (1701–1774) and so called because it originally was used as an eraser, having proven its utility for erasing the strokes of black lead pencils; for a time it was known also as the “lead-eater”.  Use to describe the waterproof overshoe is US English from 1842, the slang sense of "condom" unknown before the 1930s.  The sense of a "deciding match" (later any match) in a game or contest is from the 1590s and and may have a wholly different etymology.  The rubber stamp in the literal (noun) sense is from 1881, the figurative use to describe and “individual or institution with formal authority but no power" was noted from 1919; the verb in this sense used first in 1934.  Rubber cement is attested from 1856 (having existed since 1823 as India-rubber cement).  The rubber check (to describe one which bounces) is from 1927.

Lindsay Lohan in wetsuits, the one in pastel blue with pops of yellow, pink & royal blue by Cynthia Rowley was worn in the short film First Point (2012); it used the motif of a stained glass window.  It was made from a 2 mm fiber-lite neoprene, a synthetic rubber of the family polychloroprene, dating from 1930 and produced by polymerization of chloroprene.  Wetsuits maintain body-heat by trapping a thin layer of water between the neoprene and the skin, the thing gaining its name from the wearer being always wet, the body's heat warming the trapped water which is why a wetsuit must be tight, otherwise the gap will be too wide and heat will dissipate.

The Dead Rubber

A dead rubber in a sports series is a game, the result of which cannot affect the outcome of a series.  Thus, if one side is 3-0 up in a five match series, the remaining two games are dead-rubbers.  The origin of rubber as descriptor of a game is unknown but consensus is it’s probably the notion from bridge that when one pair is 1-0 up, if the opposing pair win the next deal, that “rubs out” the earlier advantage and the vernacular form to emerge describing this was likely “a rubber”.  To this day, the most popular form of bridge is known as rubber bridge.

The word in its original form certainly had nothing to do with the rubber extracted from trees.  Both Dr Johnson's Samuel Johnson (1709-1784) dictionary (1755-1756) and John Kersey's earlier (1702-1708) works express no doubt the term comes from the word rub and includes the meaning “to play rubbers, or a double game at any sport”.  The sports recorded as being counted in rubbers are those where there are a number of rounds, deals or games within the one match or series such as bowls and bridge.  Both make it clear rubber in the context of sport is derived from “to rub out”.

A more speculative explanation for the etymology is from the sixteenth century English game of lawn bowling.  Somewhat similar to bocce ball, the object of lawn bowling is to roll wooden balls across a flat field toward a smaller white ball so they stop as close as possible to the smaller ball without hitting it.  Theory is that the term refers to two balls rubbing together, a game-losing mistake although it’s just as likely that, as in bridge, it references the final game's potential to "rub out" or the opposing team’s earlier score.
