A whorl is a circular or spiral pattern, like the swirls you see at the tip of your finger when you look closely at your fingerprint. The word describes anything that curves around and around from a center point, forming rings or spirals that loop outward.

You can find whorls in many places. The center of a sunflower shows a whorl pattern as the seeds spiral outward. When you drop a stone in still water, the ripples spread out in circles that look like whorls. A seashell often grows in a whorl, with each curve wrapping around the one before it. Even a galaxy like the Milky Way forms a giant whorl in space, with arms of stars spiraling around its center.

In nature, whorls appear wherever growth happens in a circular pattern. Some plants have leaves arranged in whorls around the stem, with several leaves emerging from the same point and fanning out like spokes on a wheel. Hair sometimes grows in a whorl pattern, creating that stubborn spot on your head where the hair swirls in different directions and never quite lies flat.

The word captures something beautiful about how nature organizes itself: instead of straight lines and sharp corners, many things prefer to grow and flow in graceful, spiraling patterns.
