Morphology

uncertain = certain (transparent) = un + certain

The adjective is formed by negating 'certain' with 'un-', yielding a meaning of 'not certain' or 'lacking assurance'.

Etymology

Uncertain comes from the parts un- ('not') and certain ('sure'). A helpful way to remember the second meaning is to think of a person who is 'not sure' of themselves, so their voice or steps feel weak or hesitant.
