kidney
腎 centers on the kidney, the organ that filters and regulates fluids in the body.
腎 combines 臤 (a phonetic component carrying the sound) with 月 (flesh/organ), indicating a body part related to the sound ジン. The exact historical development of 臤 is uncertain, but the character is a standard phono-semantic compound for 'kidney'.
The top part 臤 looks like a sturdy frame, and the bottom 月 is flesh. Picture a sturdy, bean-shaped organ made of flesh filtering your blood: that's the kidney.
For ジン, imagine a kidney-shaped bottle of gin: gin -> ジン. The kidney filters your body like a bartender strains gin.
