What does prospectively mean?
Prospectively means in relation to the future, especially when considering an action, qualification, or designation before it becomes effective. The phrase is common in legal and institutional contexts: a rule may apply prospectively, meaning that it governs future cases rather than retroactively changing earlier ones; a person may be prospectively appointed or approved, meaning that the appointment or approval is made in advance of taking office or beginning the relevant activity. In ordinary conversation, the simpler expressions "in advance" or "for the future" are usually more natural. The word's distinctive feature is its implication of deliberate forward planning or anticipation. It does not itself guarantee that a future event will occur; rather, it describes treating something as expected, eligible, or applicable from a future point onward.

- In a way directed toward or based on a future expectation.
