盛る
もる · moru · JLPT N2 · verb-godan
to serve
🍚 moru sounds like more: serve the food, then pile on more until the dish is full
盛 = 皿 (dish) + 成 (complete): fill the dish until it is complete. Moru also means to prescribe, like filling out a full medicine order.
盛 — 成 (chéng, phonetic) + 皿 (vessel)
A phono-semantic compound: 皿 (a dish or vessel) gives the meaning, while 成 supplies the sound. The original sense was grain heaped into a ritual vessel as an offering, hence 'to fill' or 'contain' (chéng). From 'full to the brim' it extended to 'abundant, flourishing, prosperous' (shèng).
