Etymology
緘 combines 糸 (thread) with 咸, which likely contributes the sound. The idea is sealing or shutting with thread, as in tying a bag or letter closed.
Meaning mnemonic
Thread 糸 on the left and 咸 on the right: imagine using thread to sew a bag shut, sealing it completely.
Reading mnemonic
For カン, picture a can being sealed with thread: can -> カン, and the thread keeps the can shut.
