IPA: //ˈɛərbeɪs//
KK: /ˈɛrˌbeɪs/
A military airport that serves as a base for aircraft and provides facilities for the personnel who operate and maintain them.
The airbase was strategically located to support military operations.
Airbase is formed from "air" (from Old English "aer", meaning the atmosphere or sky) and "base" (from Latin "basis", meaning foundation or support). The word "airbase" refers to a foundational location for aircraft operations in the atmosphere.
Think of 'air' as the atmosphere where planes fly and 'base' as a foundation — an airbase is a foundational location for aircraft in the sky.
