The quality or state of being anterior; the condition of being in front or preceding in time or position.
From Latin 'anterior' (comparative of 'ante,' meaning 'before'), combined with the English abstract noun suffix '-ness' expressing the quality itself.
Medical professionals prefer abstract nouns like 'anteriorness' because they need to discuss anatomical properties as independent concepts—it's the linguistic equivalent of zooming out from a specific body part to discuss the principle of 'frontness' itself.
