Increasing or growing very quickly, especially in a way that becomes faster and faster over time. In math, it describes a pattern where a quantity is repeatedly multiplied by the same number.
From *exponent* plus the adjective-forming suffix *-ial*. It refers to growth or change governed by exponents in mathematics.
Exponential growth is sneaky: it starts out looking slow, then suddenly shoots up so fast it feels impossible to catch. This is why things like virus spread or compound interest can surprise people—they don’t feel big until they’re huge.
