In the Hakka language, “食” meaning “to eat” is a verb that usually collocates with nouns referring to food or drink. For example, “食飯” means “to eat rice” or “to dine,” and the meaning of “食茶” is “to drink tea.” Another special usage is “食菸,” which means “to smoke.”
There are no nouns specifically referring to "breakfast, lunch, dinner" in the Hakka language. Instead, the concept of three daily meals is expressed by using the verb “食 (to eat)” and the nouns “朝 (morning),” “晝 (noon),” and “夜 (night).” Hence, “食朝,” “食晝,” and “食夜” figuratively mean “to eat breakfast,” “to eat lunch,” and “to eat dinner.”
