'auriculoparietal' originates from New Latin/Modern anatomical formation, combining Latin 'auricula' (a diminutive of 'auris' meaning 'ear') and Latin 'parietalis' (from 'paries' meaning 'wall', used for the parietal bone).

'auriculoparietal' was formed in anatomical Latin by joining the combining form 'auriculo-' (from Latin 'auricula') with 'parietal' (from Latin 'parietalis' via medieval/modern scientific Latin) and entered English usage as a technical anatomical adjective.

Initially it literally combined the component senses 'relating to the ear' and 'relating to the parietal (wall/ skull)'; over time it has remained a specialized anatomical term meaning 'pertaining to both the auricular and parietal regions'.
