Surface Forms

impassable positive

Morphology

impassable = passable (transparent) = im + pass + able

The adjective is formed by negating 'passable' with the productive negative prefix 'in-' (realised as 'im-' before p), yielding a direct opposite meaning.

Etymology

Impassable breaks into im- ('not') and pass ('to go through'), the same root you see in passage and passport. So it literally means 'not able to be passed', which is why we use it for a road or path you cannot travel across.
