bind
稛 centers on the action of binding or tying something up, especially in the context of grain or bundles.
稛 combines 禾 (grain) with 囷, which likely contributes both sound and the idea of a round granary or enclosure, suggesting binding grain into bundles.
The left side is grain 禾, and the right side 囷 looks like a container or enclosure. Picture tying bundles of grain together and placing them inside a round bin.
For コン, imagine a con artist binding grain bundles with a trick knot: con -> コン, and the grain is tied up.
