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

'aberrantia' transformed into the English word 'aberrancy,' and eventually became the modern English word 'aberrancies' as its plural form.

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