'justification' originates from Latin, specifically the word 'justificatio,' where 'justus' meant 'just' and 'facere' meant 'to make.'

'justificatio' transformed into the Old French word 'justification,' and eventually became the modern English word 'justification' through Middle English.

Initially, it meant 'to make just or right,' but over time it evolved into its current meaning of 'showing something to be right or reasonable.'
