shore, banks
潯 centers on the edge of a body of water: the shore or banks where land meets water.
潯 combines 氵 (water) with 尋, which likely contributes the sound and may relate to measuring depth or distance along a shore. The exact historical development is uncertain.
Water 氵 beside 尋, which looks like a hand with a measuring tool. Imagine measuring the water's edge to find the shore.
For ジン, picture a gin bottle washed up on the shore: gin -> ジン, and the water brings it to the banks.
