Morphology

impenetrably = impenetrable (transparent) = im + penetrate + able + ly

Formed by adding the adverbial suffix '-ly' to the adjective 'impenetrable', a standard and predictable derivation.

Etymology

Impenetrably starts with im- meaning 'not' and the part penetrate meaning 'to go into', so think of a wall or thick fog you cannot get through. That's why something described as impenetrably is 'not able to be entered or understood', like a very hard book or a valley full of fog.
