'nonremovability' originates from English, specifically the prefix 'non-' + the noun 'removability', where 'non-' meant 'not', 'remove' meant 'to take away', and the suffix '-ability' meant 'capability or suitability'.

'removability' comes from the verb 'remove', which derives from Latin 'removere' ('re-' meaning 'back' + 'movere' meaning 'to move'); 'removere' passed into Old French and Middle English as 'remove', later forming the noun 'removability', and then modern English formed 'nonremovability' by prefixing 'non-'.

Initially the root 'remove' meant 'to move back or take away'; over time compounds like 'removability' and the negated form 'nonremovability' came to denote the (in)ability to be removed, with the current meaning focusing on the state or quality of not being removable.
