sell (grain), auction
糴 centers on the commercial exchange of grain: selling grain or auctioning it off. The core idea is transferring grain ownership through a sale.
糴 combines 入 (enter) and 米 (rice/grain) on the left with 翟 on the right, which likely contributes the sound. The left side suggests grain coming in, historically associated with buying grain, but the modern meaning has shifted to selling grain.
The left side shows 入 (enter) over 米 (rice), like grain entering a market. The right side 翟 looks like a bird overseeing the sale. Picture grain being brought in and sold at auction.
For チョウ, imagine a grain auctioneer named Chou shouting 'choh!' as he sells the rice: Chou -> チョウ, and the grain changes hands.
