'Reformation' originates from Latin, specifically the word 'reformatio,' where 're-' meant 'again' and 'formatio' meant 'forming or shaping.'

'Reformatio' transformed into the French word 'réformation,' and eventually became the modern English word 'Reformation' through Middle English.

Initially, it meant 'the act of forming again,' but over time it evolved into its current meaning of 'a religious movement or institutional reform.'
