Origin

This character pairs a mountain radical on the left, which points to the meaning of steep or dangerous terrain, with a sound component on the right that signals the pronunciation "ken." The mountain radical makes sense because precipitous places are literally found in mountainous areas—they're hard to access and risky to traverse. The combination of a geographic feature (mountains) with the danger or difficulty associated with them gives the character its meaning of something steep, inaccessible, or perilous. Over time, the meaning expanded to include abstract senses like a sharp or keen way of seeing things.
