'aviatorial' originates from English, formed from the noun 'aviator' (itself built with Latin roots), where Latin 'avis' meant 'bird'.

'aviatorial' developed from English 'aviator' (from French 'aviateur' and Late Latin 'aviator'), which ultimately comes from Latin 'avis' ('bird'); the adjective was formed in English by adding the suffix '-ial' to 'aviator'.

Initially it meant 'of or relating to aviators or flying' and this basic sense has been retained in modern usage.
