用餐
yòng cān · HSK 7
to eat a meal
🍽️ 用餐 = 用 (use) + 餐 (meal): to use a meal = to dine
用 yòng means to use or employ; 餐 cān is a meal. Together they form the formal verb for taking a meal, the kind of phrasing a restaurant sign uses for dining hours.
用 — pictograph of a bucket or wooden pail
用 originally depicted a bucket or container, possibly a sacrificial vessel made of wood. Over time it was borrowed to mean 'to use' or 'employ,' losing its concrete object sense. The modern meaning 'use' has been standard since early classical Chinese.
餐 — 歺 (bone fragment) + 又 (hand) + 食 (food)
Originally a phono-semantic compound showing a hand (又) taking food from bones (歺), with 食 (food) as the meaning component. The top portion 'cǎn' provides the sound, while 食 indicates the meaning of eating. Over time it came to mean 'meal' or 'to eat.'
