put up (a notice), put up, hoist, display, hang out, publish, describe
掲 centers on raising something so it becomes visible or known: putting up a notice, hoisting a flag, displaying an item, or publishing information.
掲 is the modern simplified form of 揭. The older form combines 扌 (hand) with 曷, which likely contributed the sound and the idea of raising or lifting by hand.
The hand radical 扌 beside the right-side shape suggests a hand lifting something up. Picture a hand hoisting a notice board so everyone can see it.
For ケイ, imagine a hand putting up a notice on a giant cake: cake -> ケイ, and the hand raises the notice for display.
