distant, far, separated, different
逈 centers on being far away in space or degree: distant, separated, or different from what is near or expected.
逈 combines the movement radical 辶 with 向, which likely contributes the sound and the idea of facing a direction, together suggesting distance or separation.
The movement radical 辶 wraps around 向 (facing). Picture walking away while still facing back: the distance grows, making things far and separated.
For ケイ, imagine a distant kayak (ケイ) paddling away on the horizon: kayak -> ケイ, and the kayak becomes a far, separated speck.
