Etymology
疉 is a variant form of 疊, which historically depicts layers piled up. The top 畾 suggests repeated fields or stacked objects, while the lower part 冖 and 彑 likely represent a cover and a base, reinforcing the idea of folding or stacking.
Meaning mnemonic
The top 畾 looks like three stacked fields, and the bottom 冖 and 彑 resemble a lid and a folded base. Picture folding a tatami mat over and over, creating duplicate layers.
Reading mnemonic
For ジョウ, imagine a stack of tatami mats in a traditional Japanese room: the word 'jō' (as in tatami-jō) cues ジョウ, and the mats are folded and piled up.
