Morphology

rubber = rub (opaque) = rub + er

Although the form is historically 'rub' + '-er', the material sense is not predictably derivable for most learners from the idea of 'something that rubs'.

Etymology

Rubber comes from the simple verb rub, which means 'to rub out', because people first used the tree 'gum' to rub away pencil marks and then called that gum by the same name; that name later became the word for the stretchy, waterproof material we use in tires and grips.
