Etymology
衛 combines 行 (to go, movement) with 韋 (leather, surround), suggesting patrolling or encircling for defense. The modern form is a simplified version of the older 衞.
Meaning mnemonic
The outer 行 suggests movement or a path, while the inner 韋 looks like a fortified enclosure. Picture guards marching around a protected area: 衛 means defense and protection.
Reading mnemonic
For エイ, imagine an 'A'-team of elite guards providing defense: 'A' -> エイ, and they protect the perimeter.
