'non-abradable' originates from the prefix 'non-' meaning 'not' and the word 'abradable', which comes from Latin 'abradere', where 'ab-' meant 'away' and 'radere' meant 'to scrape'.

'abradere' transformed into the English word 'abrade', and eventually became 'abradable' with the suffix '-able', indicating capability, and 'non-abradable' with the prefix 'non-' indicating negation.

Initially, 'abradable' meant 'capable of being worn away', but with the prefix 'non-', it evolved into its current meaning of 'not capable of being worn away'.
