retroactive

What does "retroactive" mean?
"Retroactive" describes something that takes effect from a date in the past, effectively changing the status of events that have already occurred. Imagine a clock that doesn't just start ticking now, but reaches back to adjust the records of yesterday; it is the legal or administrative equivalent of "backdating" an action. This word is most frequently found in legal, financial, or bureaucratic contexts. You will often see it paired with terms like "law," "payment," or "policy." Because it implies changing the rules after the game has already been played, it is often used with a sense of caution or specific procedural necessity.
