夏令营
xià lìng yíng · HSK 7
summer camp
🏕️☀️ 夏 summer + 令 season + 营 camp = a camp run during the summer season
营 means camp or barracks (as in 露营 to camp). 令 carries the sense of season here, like in 时令. Together 夏令营 is literally the summer-season camp.
令 — person 人 (top) + kneeling figure 卩
Originally a pictograph showing a person under a roof issuing orders to a kneeling subordinate, depicting authority giving commands. The core meaning 'command, order' extended to 'cause/make (someone do something)' and later to honorific senses like 'good' or 'your' (令尊). The phonetic role in compounds like 零 and 铃 came later.
