Dialectal Variation
British vs American Usage
Differences
In BrE, 'rubber' commonly = 'eraser'. In AmE, 'eraser' is standard; 'rubber' is informal/slang for 'condom'. In both, it means a vehicle tire (though 'tyre' is spelling variant in BrE).
Connotations
Neutral in BrE for eraser. In AmE, the primary material sense is neutral, but 'rubber' as a standalone noun often has strong sexual connotations.
Frequency
BrE uses 'rubber' for eraser daily. AmE speakers primarily use 'rubber' for the material or tire, avoiding it for eraser to prevent misunderstanding.

FAQ
Frequently Asked Questions
In everyday British English, the most common meaning is 'eraser'.
Because in American slang, 'rubber' means condom, while in the UK it would be understood as eraser, leading to potential embarrassment.
It can be both. Uncountable for the material ('a piece of rubber'). Countable for objects made from it ('two rubbers' for erasers in BrE, 'four new rubbers' for tires).
It comes from the verb 'to rub', because the material was originally used to rub out pencil marks (eraser). The name was then extended to the material itself.
