Etymology: "Inapprehensibility" is a plain stack of parts: it takes "inapprehensible", meaning not able to be grasped by the mind, and adds the suffix "-ity", which turns an adjective into a noun naming a quality. The base adjective is itself built from "apprehensible", which comes from the Latin verb "apprehendere", meaning to seize or lay hold of, which gave English its sense of grasping something mentally as well as physically. The prefix "in-" adds the negation, so the whole word names the state of resisting being taken hold of by understanding.
