ring, circle, loop
環 centers on a closed circular shape: a ring, circle, or loop. It describes anything that curves around and connects back to itself.
環 combines 王 (jewel) with 睘, which likely contributes the sound and the idea of something round. The character originally referred to a jade ring or circular ornament.
The left side 王 (jewel) suggests a precious object, and the right side 睘 looks like a round shape with a hole. Picture a jade ring worn as a circle: 環 is a ring or loop.
For カン, imagine a can rolling in a perfect circle: can -> カン, and the can's rim is a metal ring.
