Morphology

unsure = sure (transparent) = un + sure

The productive negative prefix 'un-' applied to the adjective 'sure' yields the straightforward meaning 'not confident/certain', which is directly inferable by learners.

Etymology

Unsure is the negative un- meaning 'not' plus sure, a word that means 'certain' or 'confident' and that you can also see in ensure and assure, so unsure means 'not certain' or 'not confident'.
