unsolved = solved (transparent) = un + solve + ed

Formed by productive prefixation (un- + solved) yielding the straightforward negation 'not solved'.

Etymology

Unsolved begins with un- meaning 'not' and the rest is solve, which comes from an old word meaning 'to loosen' and appears in solution. So, unsolved means 'not fixed' or 'not answered', which is why we use it for problems, mysteries, or cases that have no solution yet.
