Surface Forms

nonactive positive

Morphology

nonactive = active + active (transparent) = non + active

Formed by the productive negative prefix 'non-' added to the adjective 'active', producing a straightforward negated meaning.

Etymology

Nonactive is made from the parts non- meaning 'not' and active meaning 'doing' or 'producing an effect', so a nonactive ingredient in medicine is like a quiet filler that does not produce a physical or therapeutic effect.
