'aneretic' originates from Greek, specifically the word 'anaretikos,' where 'anairein' meant 'to take up, destroy.'

'anaretikos' changed from the Greek word to Medieval Latin 'anareticus,' and eventually became the modern English word 'aneretic.'

Initially, it meant 'destructive or fatal,' but over time it evolved into its current meaning of 'relating to the critical degree in astrology.'
