21 meanings of rubber

Practice

  1. 1
    nouncountable or uncountable
    A stretchy, elastic material (either tapped from certain trees or manufactured synthetically) that returns to its original shape after being stretched or bent.

    Manufacturers blend natural and synthetic rubber to get the durability they need.

    The seal around the door is made of soft rubber that keeps water out.

  2. 2
    nouncountable or uncountable
    Pliable material made from the milky sap of the rubber tree; chemically, a hydrocarbon polymer built from isoprene units.

    Tappers score the bark each morning to gather the latex that becomes rubber.

    Raw rubber is processed and cured before it can be used in tires.

    Note

    The material is named after one of its own uses. The word began as rub + -er, "a thing that rubs", and the substance took the name from its knack for rubbing out pencil marks, pushing aside the older word caoutchouc. Natural rubber is the precise term when the tree product needs to be told apart from the synthetic look-alikes.

  3. 3
    nounAustraliaBruneiIndiaNew ZealandUKcountable
    A small implement used to rub out pencil marks from paper, typically made of rubber or a similar soft material.

    He pulled a rubber from his pencil case to correct the wrong answer.

    The invigilator handed out spare rubbers to students who had forgotten theirs.

    Similareraser

    Note

    Here the word is still doing the rubbing-out that named the material. It is the ordinary classroom word in the UK, Australia, New Zealand, India and Brunei, listed casually among pens, pencils and rulers. Eraser is the safer choice with North American listeners. In the US and Canada, a request to borrow a rubber points first to the slang for a condom.

  4. 4
    nounslangCanadaUScountable
    A condom, especially the external type worn during sex to prevent pregnancy and infection.

    She reminded him to keep a rubber in his wallet just in case.

    The clinic handed out free rubbers to anyone who asked.

    Similarcondom

    Note

    Slang of the US and Canada, named for what the device is made of rather than for any rubbing. It is frank but casual, more at home in a lyric than a clinic. Denzel Curry raps advice to use one, and the gym coach in Tina Fey's Mean Girls (2004) tells the class to "take some rubbers". Use and carry are the verbs it keeps company with.

  5. 5
    nounCanadaUSuncountableplural
    Waterproof overshoes, such as galoshes, pulled on over ordinary shoes to keep them dry in rain or snow.

    One rubber had split at the heel, so Grandpa finally bought a new pair before the first snowfall.

    The children's rubbers were lined up by the door, dripping from the rain.

    Similargaloshes, overshoes

    Note

    A North American word, used in the US and Canada and nearly always plural. You pull on your rubbers, and the aunt in Henry Blake Fuller's Bertram Cope's Year (1919) urges a young man to provide himself "with rubbers and an umbrella". A single rubber means one overshoe of the pair. The name comes from the waterproof material, not from rubbing.

  6. 6
    nounslanguncountable
    Tires considered collectively, especially the high-performance tires used in motor racing.

    The team gambled on softer rubber to gain speed in the closing stages.

    Worn rubber cost him the lead as his grip faded into the last corner.

    Similartires

    Note

    Racing slang that treats tires as a single stock, like fuel. Because the word is uncountable here, a driver gets new rubber or fresh rubber rather than new rubbers. Speaking of grip, wear and tire choice in terms of the material itself is what gives this use its pit-lane flavor.

  7. 7
    nouncountable
    The flat rectangular slab set into the pitcher's mound, which a pitcher must keep contact with while delivering the ball.

    He stepped off the rubber to shake off the catcher's sign.

    The umpire warned him for leaving the rubber too early on his delivery.

    Note

    Baseball also calls it the pitcher's plate or the pitcher's rubber, but the bare word is enough on the field. The verbs it takes describe foot contact. A pitcher toes the rubber to begin a delivery and steps off the rubber to reset. Nothing is rubbed against it. Like the other non-rubbing senses, its name comes from the material.

  8. 8
    nounCanadaUScountable
    A deciding game or match played to break a tie, after each competitor has won an equal number of the previous games.

    With the series tied at one apiece, the rubber would decide the champion.

    He saved his best performance for the rubber and clinched the title.

    Similardecider, tiebreaker

    Note

    The North American use narrows the word to the decider alone. Each side has won equally, and one more game settles it. The fuller phrase rubber match makes the meaning plain and is the safer form for readers who know the word mainly from cards, where it names the whole series.

  9. 9
    nouncountable
    A complete series of games (an odd number, so a tie is impossible) especially the best-of-three played in bridge or whist.

    The two pairs settled in for a rubber of whist by the fire.

    She won the rubber after taking two games to one.

    Similarseries

    Note

    This game word is a separate rubber, unrelated to rubbing or to tree sap, and where it came from is unknown. The card table is its home. Robert Huish's The Red Barn (1828) has a pair that "won the first rubber, winning the two first games running". Winning the first two games settles a best-of-three, so the third is never played.

  10. 10
    nouncountable
    A single game or match forming one part of a longer series between two competitors, especially in racket sports.

    Britain took the opening rubber in the Davis Cup tie before squandering their lead.

    The match came down to the final rubber between the two top-ranked singles players.

    Similarmatch, game

    Note

    Racket sports turn the card-table usage inside out. A rubber here is one match, and the whole contest goes by another name, usually tie. A Fed Cup report of 2015 speaks of "the first rubber of the tie". Badminton league rules can specify how many rubbers make up a match. Keep it distinct from the whole series, which is what card players mean.

Origin

Formed from 'rub' plus '-er'. The name for the substance comes from its use as an eraser (rubbing out marks), replacing the earlier word 'caoutchouc'. Meanings unrelated to rubbing or erasing later came from the name of the substance itself.
