'involuntarily-returned' originates from the combination of 'involuntarily' and 'returned'. 'Involuntarily' comes from Latin 'involuntarius', where 'in-' meant 'not' and 'voluntarius' meant 'willing'. 'Returned' is derived from Old French 'retourner', where 're-' meant 'back' and 'tourner' meant 'to turn'.

'Involuntarily' changed from the Latin word 'involuntarius' and eventually became the modern English word 'involuntarily'. 'Returned' evolved from the Old French 'retourner' to the modern English 'returned'.

Initially, 'involuntarily' meant 'not willing', and 'returned' meant 'to turn back'. Over time, 'involuntarily-returned' evolved to mean 'returned without one's own will'.
