'reprocess' originates from the prefix 're-' meaning 'again' and the word 'process' from Latin 'processus', meaning 'a going forward'.

'processus' transformed into the French word 'processer', and eventually became the modern English word 'process'.

Initially, it meant 'to go forward again', but over time it evolved into its current meaning of 'to treat or prepare by a special method again'.
