not having air-filled spaces
Etymology
'unpneumatized' originates from English, formed by the negative prefix 'un-' + 'pneumatize'; 'pneumatize' ultimately derives from Greek 'pneuma' where 'pneuma' meant 'breath, wind'.
'pneuma' (Greek) gave rise to Late Latin/New Latin elements 'pneumat-' and verbs formed as 'pneumatize' in scientific English (via French/Latin formation patterns), and English added the prefix 'un-' and the adjectival/past-participle suffix '-ed' to create 'unpneumatized'.
Originally related to 'pneuma' meaning 'breath' or 'air', used in scientific contexts to mean 'to furnish with air-filled cavities'; with the addition of 'un-' the modern term means 'not having those air-filled cavities'.
