checkup, seeing, diagnose, examine
診 centers on careful inspection to understand a condition: examining a patient, diagnosing an illness, or checking something thoroughly.
診 combines 言 (words, speech) with 㐱, which likely contributes the sound and may relate to examining or scrutinizing. The character suggests using words to investigate or diagnose.
A doctor uses words (言) to ask about symptoms and the right side (㐱) looks like a person under a microscope. Together, 診 means examining and diagnosing.
For シン, imagine a doctor examining a patient's shin: shin -> シン, and the doctor's words (言) diagnose the problem.
