conceal, hide, cover
隠 centers on making something unseen or unknown: concealing, hiding, or covering something from view or knowledge.
隠 is the modern simplified form of 隱. The older form combines ⻖ (hill, mound) with a phonetic component that also suggests covering or hiding. The modern form replaces the right side with a simplified structure containing 爫, 彐, and 心.
The left side ⻖ suggests a mound or hill, and the right side has a hand 爫 reaching over something 彐 to cover the heart 心. Picture hiding a secret heart behind a hill, covering it with your hand.
For イン, imagine hiding inside an inn: inn -> イン, and you conceal yourself behind the hill-like walls.
