'aberrancy' originates from Latin, specifically the word 'aberrantia,' where 'ab-' meant 'away from' and 'errare' meant 'to wander.'

'aberrantia' transformed into the Medieval Latin word 'aberrantia,' and eventually became the modern English word 'aberrancy.'

Initially, it meant 'wandering away from the norm,' but over time it evolved into its current meaning of 'deviation from the normal or typical.'
