'removableness' originates from English, specifically formed from the adjective 'removable' plus the suffix '-ness', where the suffix '-ness' meant 'state or quality', and 'removable' ultimately derives from Latin 'removēre' (via Old French 'remover'), where 're-' meant 'back' and 'movēre' meant 'to move'.

'removableness' changed from formations based on Middle English/Old French 'remove' (from Latin 'removēre') and the adjectival suffix '-able' (from Latin '-abilis'), developing as 'removable' + '-ness' in Early Modern English and eventually becoming the modern English noun 'removableness'.

Initially, the Latin root meant 'to move back' or 'to remove', but over time the derived English formations came to denote the modern sense of 'the quality of being able to be removed'.
