'evangelical' originates from Greek, specifically the word 'euangelion,' where 'eu-' meant 'good' and 'angelion' meant 'message.'

'euangelion' transformed into the Latin word 'evangelium,' and eventually became the modern English word 'evangelical' through Old French.

Initially, it meant 'good news or gospel,' but over time it evolved into its current meaning of 'relating to the Christian gospel or zealous advocacy.'
