叠
dié · HSK 7
to fold
🧣 Three 又 (again) stacked on a table 宜 — again and again, layer on layer
The character literally piles up repetition: three 又 (again) sit atop 宜. Folding is doing the same crease again and again, building layers each time you repeat the action.
叠 — three 又 (hands) over 宜 (shelf/altar)
Originally written with three 田 stacked above 宜, depicting layers piled on a stand — the core idea of stacking or repeating. Modern form simplifies the top to three 又. It now means to fold, pile up, or repeat.
