A resurgence is when something that had faded away or declined comes back with renewed strength and energy. Think of a sports team that was struggling all season but suddenly starts winning game after game. That's a resurgence: a powerful return.

The word often describes comebacks that feel almost unexpected. When vinyl records made a resurgence in the 2010s, it surprised many people because everyone thought CDs and digital music had replaced them for good. When a forest grows back after a fire, naturalists might describe it as a resurgence of life in that ecosystem.

You'll see this word used for trends, ideas, movements, and even diseases. A resurgence of interest in learning Latin means more students are suddenly choosing to study it again. A resurgence of measles means the disease is spreading again in places where it had been rare.

The word carries a sense of vitality and momentum. A resurgence means something is returning with real force and energy, coming back strong rather than weak. When people talk about a resurgence, they mean something is genuinely back in action, fully engaged and growing.
