'exodus' originates from Greek, specifically the word 'ἔξοδος' (exodos), where 'ex-' meant 'out' and 'hodos' meant 'way'.

'ἔξοδος' transformed into the Latin word 'exodus', and eventually became the modern English word 'exodus'.

Initially, it meant 'a going out or departure', but over time it evolved into its current meaning of 'a mass departure of people'.
