'deviator' originates from Latin, specifically the word 'deviator', where 'de-' meant 'away from' and 'via' meant 'way'.

'deviator' changed from the Latin word 'deviator' and eventually became the modern English word 'deviator'.

Initially, it meant 'one who turns away from a path', but over time it evolved into its current meaning of 'a person or thing that deviates'.
