'antero-superior' originates from New Latin/medical Latin, combining the prefix 'antero-' (from Latin 'ante' meaning 'before, in front') and 'superior' (from Latin 'superus' meaning 'above, higher').

'antero-' is a combining form derived from Latin 'anterior' (itself from 'ante'), and 'superior' comes from Latin 'superus'; the compound form 'antero-superior' developed in modern anatomical and medical usage to specify a directional relation and entered English via medical Latin and nineteenth/20th-century anatomical terminology.

Initially formed to specify relative position as 'in front and above'; the meaning has remained consistent and continues to denote a front-and-upper anatomical location.
