Morphology

retroactive = active (transparent) = retro + active

The adjective is a direct combination of 'retro' (backward) + 'active' (in effect), so its meaning 'having effect backward in time' is derivable from the parts.

Etymology

Retroactive comes from retro- meaning 'back', as in retrofit, and active meaning 'doing' or 'taking effect'. So something retroactive 'acts back' to an earlier date, which is why a retroactive law affects things that already happened.
