Etymology: Latin "ruber" means "red," an adjective built on an older root for reddish colour. Its relative "rubeus" passed through Medieval Latin "rubinus" and Old French "rubi" to give English "ruby," so the colour word also became the name of a gem. The plant-derived elastic material is a different word. English "rubber" comes from the verb "rub," with the agent ending "-er," and the name reflects its early use: the substance could rub out pencil marks. The resemblance to Latin "ruber" is a matter of spelling and sound, not shared ancestry.
