糧

Phono-semantic compound:

米 (쌀 미, “rice, grain”) — semantic component, indicates relation to food/grain.

量 (량, “to measure, quantity”) — phonetic component, also carries the nuance of “measured amount.”

Thus originally meant “measured grain” or “food rations,” extended to mean general provisions and food supply.

糧食 (양식) — food, provisions

食糧 (식량) — grain, food supply

軍糧 (군량) — military provisions

口糧 (구량) — daily rations, subsistence food

In historical Chinese usage, the character often appeared in contexts of warfare and logistics, where reliable grain supplies (兵糧) determined the outcome of campaigns.

Because of the link with 量 (“measurement”), 糧 emphasizes food as a countable, apportioned resource, not just raw crops but organized rations.
