'areologic' originates from Greek, specifically the elements 'Areios' (of Ares, the Greek god corresponding to Mars) and 'logos' (study), where the combining form 'areo-' refers to Mars and 'logos' meant 'study'.

'areologic' was formed via Neo-Latin/Modern scientific coinage from elements such as Neo-Latin 'areologicus' or the noun 'areology' (formation from Greek roots) and eventually became the modern English adjective 'areologic'.

Initially it carried the sense of 'of or pertaining to Ares' (the deity), but over time it evolved into the technical sense 'relating to the planet Mars or the scientific study of Mars'.
