Morphology

unbound = bound (transparent) = un + bound

Though used in a technical sense, 'un-' simply negates the adjective 'bound' (meaning 'held in combination'), so the derivation is straightforward.

Etymology

Unbound comes from un- 'not' plus bind 'to hold or join', which you can also see in the common word bond. In science, an unbound substance is not held to something else and so is free to move or act.
