steepen

Imagine hiking up a hill. If the path steepens, the climb gets harder because the angle of the hill increases. But "steepen" is not just about real hills. It can also describe a trend or change that becomes sharper or more intense. For example, if a company's losses steepen, it means the losses are growing faster than before. Think of it this way: something that was already rising, falling, or slanting is now doing so more sharply.

To steepen something means to make it more inclined, sharper in slope, or more rapid in its rate of change. It is most commonly used to describe physical inclines, such as a road that steepens as it winds up a mountain or a hiking trail that becomes increasingly challenging. When you say, "The path began to steepen after the bridge," you are suggesting that the climb became noticeably more vertical and difficult from that point onward.

Beyond geography, steepen is also common when people talk about charts, rates, and trends. It describes a line or curve becoming sharper. In finance, for example, people may say a yield curve is steepening, which means the gap between short-term and long-term yields is growing. More generally, if losses, costs, or declines steepen, they are increasing or worsening at a faster rate than before.

It is important to distinguish steepen from "steeping." While "steeping" tea involves soaking leaves in water to extract flavor, steepen is strictly about the angle or the rate of escalation. It is the transition from a gentle incline to a sharp one. So, whether it's a mountain path becoming a struggle or a set of costs rising more aggressively, to steepen is to turn up the tilt and increase the challenge.
