Etymology
甲 is a pictograph of a hard outer covering, such as a seed shell or armor plate, with the vertical stroke representing the seam or ridge. The modern form retains this basic shape.
Meaning mnemonic
Picture a hard shell with a ridge running down the middle: 甲 is armor, a carapace, or the top of the foot. It also represents the first rank, like the top of a class.
Reading mnemonic
For コウ, imagine a coat of armor: coat -> コウ, and the hard shell protects the warrior.
