Abbreviation for Civil Aviation Authority, the regulatory body overseeing aviation safety and standards. Can refer to various national aviation authorities.
Acronym formed from Civil Aviation Authority, where each component comes from Latin: civilis (relating to citizens), from avis (bird) for aviation, and auctoritas (power/influence) for authority. The acronym emerged in the 20th century as aviation regulation became formalized internationally.
The CAA acronym demonstrates how modern bureaucratic language creates new 'words' from initial letters, essentially forming a linguistic shortcut for complex institutional concepts. Interestingly, aviation terminology heavily borrows from bird-related Latin words, connecting human flight to its natural inspiration.
