inquire, fathom, look for
尋 centers on seeking or measuring depth: inquiring to understand something, looking for something hidden, or figuratively plumbing the depths of a matter.
尋 originally depicted two hands measuring a length, related to the idea of a fathom (a unit of arm span). The modern form is simplified and its component breakdown is not fully transparent, but it retains the core idea of measuring or seeking.
The top part looks like a hand reaching out, and the bottom 寸 suggests a measured action. Imagine someone stretching out their arms to fathom the depth of a pool while looking for a lost object.
For ジン, picture a genie (ジン) rising from a lamp when you inquire deeply: genie -> ジン, and the genie helps you fathom the mystery.
