Question

retroactive The fact that the tax hike was retroactive annoyed the public the most. ˌrɛtroʊˈæktɪv

Accepted Answer

Intended to apply or take effect at a date in the past. We normally think of time as constantly moving forward. Since retroactive seems to defy time's forward movement, retroactive taxes, laws, and regulations are often seen as particularly obnoxious and unfair. (See also ex post facto.) But nobody ever objects to receiving a retroactive raise at work. When we judge historical people and events in terms of present-day morality and attitudes, our retroactive judgments may indicate that we're too impressed with ourselves and ignorant of history
