Etymology
Etymology Information

'posterodorsally' is a modern English (anatomical) formation combining the prefix 'postero-' (from Latin 'posterus') and 'dorsal' (from Latin 'dorsum'), with the English adverbial suffix '-ly'. In Latin, 'posterus' meant 'coming after, behind' and 'dorsum' meant 'back'.

Historical Evolution

'posterodorsal' developed in anatomical/medical Latin and English by compounding 'postero-' + 'dorsal' to indicate a position that is both posterior and dorsal; English then formed the adverb 'posterodorsally' by adding '-ly'.

Meaning Changes

Originally the elements separately meant 'behind' ('posterus') and 'back' ('dorsum'); combined in anatomical usage they came to denote a single directional/positional concept: 'toward the posterior and dorsal surface', which is the current meaning.
