Morphology

octothorpe = octo + thorpe

A mid-20th-century jocular coinage: although 'octo-' suggests 'eight', the nonce element 'thorpe' has no productive meaning here, so learners cannot reliably derive 'hash sign' from the parts.

Etymology

Octothorpe is a playful name made from octo- 'eight' and a jokey ending -thorpe. A helpful way to remember it is to think of the # symbol having eight ends where the lines cross, and the octo- part is the same 'eight' in octagon and octopus. The word was invented for the telephone key, so octothorpe simply names the familiar '#' sign.
