Etymology

珪 combines 王 (jade) with 圭, which likely contributes the sound and may also represent a jade tablet shape. The character specifically denotes a jade scepter or authority tablet.

Meaning mnemonic

The left side 王 (jade) and the right side 圭 (a stacked-earth shape) together suggest a jade tablet held by a ruler. Picture a gleaming jade scepter marked with the 圭 pattern, symbolizing authority.

Reading mnemonic

For ケイ, imagine a king (K) holding the jade scepter and saying 'A' (ei) as he grants authority: K + ei -> ケイ. The king's jade tablet makes the sound ケイ.
