jiggle

If you've ever watched a bowl of jelly on a plate, you've seen this kind of movement. It describes a small, light shake that often feels bouncy, loose, or a little unsteady. Your stomach might jiggle when you laugh really hard, or your keys might jiggle in your pocket when you run. You can also make something jiggle by moving it gently, like a loose tooth or a door handle. Sometimes things jiggle because they are not quite firm or secure; for example, a wobbly table can make everything on top move a little. It is more than just shaking because it usually suggests a soft, repeated motion.

To jiggle something means to move it with small, quick, light shaking motions. Think of the way gelatin desserts wobble, or the way keys move in your pocket when you walk. It is not a strong or violent shake. Instead, it is usually a gentle back-and-forth movement, often with a soft or bouncy feel. For example: "She jiggled the handle to see if the door was locked," or "My keys jiggle in my pocket when I run."

As a verb, to jiggle often describes causing that movement on purpose. You might jiggle a loose door handle to see if it's locked, or jiggle a key in a stubborn lock to get it to turn. It can also describe movement that happens by itself, especially when something is loose, soft, or bouncing as it moves.

The word usually carries a sense of lightness and informality. Because of its link to soft materials, loose objects, and playful movement, it is not often used in serious or formal contexts. You would not normally describe the force of an earthquake this way, but you could use it for a child shaking a toy, a bowl of jelly on a tray, or a loose handle moving in your hand. Whether it is a dessert, a key, a handle, or part of the body, jiggle captures that small, repeated, slightly bouncy movement.
