moon cake
🥮 月 (moon) + 饼 (cake/pastry) = moon cake
月 means moon and 饼 is a round flat pastry or cake. Together they name the dense round pastries eaten at Mid-Autumn Festival, when the moon is fullest.
月 — pictograph of crescent moon
月 is a pictograph of a crescent moon, chosen over a full circle to distinguish it from 日 (sun). The inner strokes originally depicted the moon's shadow or markings. As a radical it often relates to the moon, time, or (via a lookalike form of 肉 'flesh') body parts.
饼 — food radical 飠/食 + 并 (bìng, phonetic)
饼 is a semantic-phonetic compound. The left side 食/飠 ('food, eat') signals the meaning category, while the right side 并 supplies the sound. Originally referring to round flat wheat cakes, it now broadly names cakes, biscuits, and pancakes.
