Etymology: The most surprising thing about "rubber" is that the material is named after the tool used to erase pencil marks. English speakers first used "rub" as a verb in the ordinary sense of pressing and moving something across a surface, and the "-er" ending turned that action into a thing that does the rubbing. Early rubbers were simply pieces of material used to rub things clean, and the eraser sense came first. The stretchy substance arrived later. When it was first imported to Europe, the gummy latex was used as a way to remove pencil marks, so the new material was called by the same name. Its tendency to rub out marks was the reason it got the label, and other meanings of "rubber", such as the card-game sense or the sense for a person who rubs or massages, developed separately from that original naming of the substance.
