When something changes or improves appreciably, it does so in a way that is noticeable or measurable. It's more than just a slight difference; it's something you can actually perceive. Think of it like turning up the volume on your favorite song; you hear the change. "Appreciably" indicates a change that's significant enough to be recognized or valued. Unlike an insignificant amount, it makes a real difference. For example, the weather cooled appreciably after the storm.
