Etymology

海 combines 氵 (water) with 每, which likely contributed the sound and originally depicted a body of water. The modern form keeps the water radical and the phonetic component 每.

Meaning mnemonic

The left side is water 氵, and the right side 每 looks like a person with a hat standing by the shore. Picture someone gazing out at the vast sea.

Reading mnemonic

For カイ, imagine a kite flying over the ocean: kite -> カイ, soaring above the sea.
