'apopemptic' originates from Greek, specifically the word 'apopemptikos', where 'apo-' meant 'away' and 'pemp- (from pemptein)' meant 'to send'.

'apopemptic' changed from the Greek word 'apopemptikos' and passed into Late/Neo-Latin forms (e.g. 'apopempticus') before entering modern English as 'apopemptic'.

Initially, it meant 'pertaining to sending away or to departure', but over time it evolved into its current meaning of 'relating to farewell or parting'.
