Morphology

reactivation = reactivate (transparent) = re + activ + ation

The noun is a regular and fully predictable -ion formation from the verb 'reactivate'.

Etymology

Reactivation comes from the parts re- meaning 'again' and activate meaning 'make active', the same root as active and action. Think of a sleeping illness waking up again; that's why reactivation is used for a disease or virus becoming active once more.
