Morphology

uncertain = certain (transparent) = un + certain

The prefix 'un-' clearly negates the meaning of 'certain', making the word transparently understood as 'not certain'.

Etymology

Uncertain comes from the parts un- ('not') and certain ('sure' or 'fixed'). So if something is uncertain it is 'not sure' or 'not fixed', which is why it is not definite or may change.
