Morphology

unexplained = explained (transparent) = un + explain + ed

Formed by negating the participial adjective 'explained' with productive 'un-', yielding the direct meaning 'not explained'.

Etymology

Unexplained starts with un- meaning 'not' and comes from explain, which is related to the simple word plain and means 'to make clear'. So unexplained means 'not made clear' or having no known cause.
