jet

A "jet" most commonly makes people think of a fast airplane, the kind that can carry you across countries or oceans in a short time. But the word has other meanings too. It can also mean a strong stream of liquid or gas shooting out with force, like a jet of water from a hose. And "jet" can refer to a deep black stone that is often used in jewelry.

Think about it this way: you might travel by jet to a faraway city, watch a jet of water shoot into the air, or admire a necklace made of jet beads. In each case, the word suggests speed, force, or a deep black color.

The word "jet" is surprisingly versatile. Most people first think of a *jet aircraft*, a fast airplane powered by jet engines and used for quick travel over long distances. That is the most common meaning today, especially in everyday speech. But the word also has other meanings that are still useful and worth knowing.

One older meaning of "jet" refers to a dark, hard material formed from wood under pressure over a very long time. It can be polished until it becomes glossy black, so it has been used for centuries in jewelry and decoration. It became especially well known in Victorian mourning jewelry. This sense also helps explain the expression "jet-black," which means intensely black.

Another meaning of "jet" is a *strong, narrow stream of liquid or gas forced out at high speed. You can talk about a jet of water, a jet of steam*, or the hot gases that shoot out of an engine. This idea of something being pushed out with force is part of the reason the airplane is called a jet.

So whether you are flying across the sky in a *jet plane, looking at jet jewelry, or watching a jet of water* burst from a pipe, the word can point to speed, force, or a rich black color. The exact meaning depends on the context, but each use is clear once you see the setting.
