intuition, perception, check, compare, sixth sense
勘 centers on a deep, often instinctive, form of understanding: intuition, perception, or a sixth sense. It also extends to the act of checking or comparing, as if using that inner sense to verify something.
勘 combines 甚 (extreme, very) with 力 (power, effort), suggesting the idea of exerting mental effort to reach a deep understanding or to check something thoroughly.
The left side 甚 looks like a person deeply focused, and the right side 力 is strength. Imagine using all your mental strength to tap into your intuition, like a sixth sense that checks and compares things without obvious reasoning.
For カン, picture a can of intuition: you open the can and a burst of sixth sense comes out. Can -> カン, and the can holds your deep perception.
