'recoveree' originates from English, specifically formed from the verb 'recover' plus the suffix '-ee' (a nominalizing suffix meaning 'person who is the object/recipient'), where 'recover' meant 'to regain health or strength'.

'recoveree' was created in modern English by adding the suffix '-ee' (from French past-participle/adjectival endings) to the verb 'recover.' The verb 'recover' came into Middle English from Old French 'recoverer' (also spelled 'recovrer'), which in turn derives from Latin 'recuperare'.

Initially, related forms of 'recover' meant 'to get back, regain' (from Latin 'recuperare' meaning 'to get back'). Over time the verb kept the sense of regaining health or property, and the derived noun 'recoveree' has come to mean 'a person who has regained health or normal condition.'
