'rebel' originates from Latin, specifically the word 'rebellare,' where 're-' meant 'again' and 'bellare' meant 'to wage war.'

'rebellare' transformed into the Old French word 'rebeller,' and eventually became the modern English word 'rebel' through Middle English.

Initially, it meant 'to wage war again,' but over time it evolved into its current meaning of 'to resist authority or control.'
