Study
Etymology
階 combines ⻖ (hill, mound, or steps) with 皆, which likely contributes the sound. Together they suggest a stepped rise like a stairway or tiered levels.
Meaning mnemonic
The left side ⻖ looks like a stepped hill or mound, and the right side 皆 suggests a row of similar things. Picture a staircase where each step is one of many identical levels.
Reading mnemonic
For カイ, imagine climbing stairs to a high floor and looking out at a calm bay: bay -> カイ, and each storey gives a better view of the bay.
