Etymology
'antero-posterior' originates from New Latin combining form, specifically 'antero-' from Latin 'ante' meaning 'before, in front' and 'posterior' from Latin 'posterior' (comparative of 'post') meaning 'after, behind'.
'antero-posterior' developed as a compound in New Latin (antero- + posterior) used in anatomical and medical Latin and entered modern English usage in the 19th century as 'antero-posterior' (also written 'anteroposterior').
Initially formed from elements meaning 'before' and 'after' (front and back), it evolved into the technical term meaning 'relating to or extending from front to back' in anatomical contexts.
