Synonym discussion

Sense: noun/1

Rubber, latex, silicone, plastic, and elastic are all flexible materials but they are not interchangeable. Rubber is the general term for the tough, stretchy substance — whether natural (from tree sap) or synthetic — used in tyres, soles, and seals. Latex is specifically the raw milky liquid tapped from rubber trees before it is processed into solid rubber; you might sleep on a latex mattress but you would not call it a rubber mattress. Silicone is a synthetic material that stays flexible at high temperatures and is used in bakeware and medical implants — it feels rubbery but is chemically quite different. Plastic is a huge family of synthetic materials that can be rigid or flexible; a plastic bag is not rubber, even though both are made from chemicals. Elastic is not a material but a property: rubber has elastic, meaning it stretches and snaps back. So: a rubber band stretches because it is elastic; a surgeon's glove is made of latex rubber; a baking mat is made of silicone (not rubber); a shopping bag is plastic (not rubber).

Etymology

English

The word 'rubber' was coined in England in the 1780s from the verb 'rub' plus the agent suffix '-er'. When the elastic material from South American trees first arrived in Europe, one of its earliest and most popular uses was for rubbing out pencil marks — hence the name. Before this, people used bread crumbs or pieces of stone to erase writing. The substance itself was initially called 'India rubber' because it came from the Indies (the West Indies, where it was collected). Over time, the name shortened to simply 'rubber' and spread to cover the material itself, even when not used for erasing.
