Morphology

retroactively = retroactive (transparent) = retro + act + ive + ly

The adverb 'retroactively' is clearly derived from the adjective 'retroactive', indicating the manner of the action.

Etymology

Retroactively comes from retro- meaning 'back', active meaning 'to act', and the ending -ly meaning 'in a way'. So to do something retroactively is to 'act back' — to apply a rule, payment, or decision to an earlier date, which is why it affects things that already happened.
