'horoscopy' originates from Greek, specifically the word 'horoskopos,' where 'hora' meant 'hour' and 'skopos' meant 'observer.'

'horoskopos' transformed into the Latin word 'horoscopus,' and eventually became the modern English word 'horoscopy' through Middle English.

Initially, it meant 'observer of the hour,' but over time it evolved into its current meaning of 'the practice of casting horoscopes.'
