leisure
遑 centers on the idea of free time or leisure, a period when one is unhurried and has no pressing obligations.
遑 combines 辶 (movement) with 皇, which likely contributes the sound and may suggest a sense of expansiveness or leisure. The exact historical development is uncertain.
The movement radical 辶 surrounds 皇, like a leisurely stroll through an imperial garden. When you have leisure, you can move without hurry.
For カン, imagine a can of leisure: you open a can and out pours endless free time. Can -> カン, and the leisure flows out.
