Morphology

unfounded = founded (transparent) = un + found + ed

The adjectival base 'founded' (having a basis) is negated by the productive prefix 'un-', yielding a predictable 'not based' meaning.

Etymology

The word unfounded has un- meaning 'not' and found, as in foundation, meaning 'base' or 'ground'. So unfounded means 'not based', like a claim or fear with no real evidence.
