IPA: /ˈskaɪbɒks/
KK: /ˈskaɪˌbɑks/
A private area located high up in a sports stadium, often enclosed and designed for watching events comfortably, usually with extra amenities.
The fans enjoyed the game from their luxurious skybox, complete with catering and a great view.
Skybox → It is formed from "sky" (from Old Norse *ský, meaning cloud or sky) and "box" (from Old English *box, meaning a container). The word "skybox" refers to a container or enclosure located in the sky, typically used for viewing events from a high vantage point.
Imagine a 'container' ('box') that is high up in the 'clouds' ('sky') — that's why a skybox is a special viewing area high above.
