'astrologer' originates from the Greek word 'astrologos', where 'astro-' meant 'star' and 'logos' meant 'study or discourse'.

'astrologos' transformed into the Latin word 'astrologus', and eventually became the modern English word 'astrologer' through Old French 'astrologe'.

Initially, it meant 'one who studies the stars', but over time it evolved into its current meaning of 'a person who interprets the influence of stars and planets on human affairs'.
