Etymology
Etymology Information

'nonpneumatic' originates from English, formed by the prefix 'non-' + the adjective 'pneumatic', where 'non-' meant 'not' and 'pneumatic' ultimately comes from Greek 'pneuma' meaning 'breath' or 'wind'.

Historical Evolution

'pneumatic' came from Greek 'pneumatikos' and Latin 'pneumaticus', passed into French as 'pneumatique' and then into English as 'pneumatic'; the productive prefix 'non-' (meaning 'not') was attached in English to create 'nonpneumatic'.

Meaning Changes

Initially 'pneumatic' related to 'breath' or 'wind' (from Greek), and later came to mean 'operated by or containing compressed air'; 'nonpneumatic' therefore came to mean 'not operated by or not containing compressed air' or more generally 'not air-filled'.
