'unerasable' originates from the prefix 'un-' meaning 'not' and the word 'erase' from Latin 'erasus', meaning 'to scrape out'.

'erase' changed from the Latin word 'erasus' and eventually became the modern English word 'erase'.

Initially, 'erase' meant 'to scrape out', but over time it evolved into its current meaning of 'to remove or delete'.
