As a noun, 馂 is the food left behind; as a verb, it is someone eating another person’s remainder.
How was 馂 used in older Chinese texts?
Ritual rules give it a concrete setting.
馂 in classical Chinese appears in the Yili (“Rites and Ceremonies”), a ritual manual associated with the Warring States period. It describes attendants eating what the host and bride left after a marriage rite.
Other ritual passages describe family members finishing parents’ food, leftover food not being offered again, and a ritual representative eating what remained of an offering. In the Han period, Shuowen Jiezi, a Chinese dictionary, defines traditional 餕 as food left after a meal, with 食 as the meaning element and 夋 as the sound element.
