Trench

Imagine you are playing in a sandbox and you start digging a really deep hole. You dig and dig until the hole is so deep that you can't even see the top anymore. Now, imagine that hole is not in a sandbox but is instead on the ground and is much, much longer. This long, deep hole is called a trench.

Trenches are often dug in the ground for specific purposes. For example, builders may use a trench to lay pipes for a new house. Farmers may dig trenches to drain water from their fields. In the military, trenches are often dug for protection during battles.

Trenches can be dangerous because they are so deep and narrow. You could fall into one and hurt yourself or get stuck. That's why it's important to be careful around trenches and never play near them or in them without adult supervision.

Now you know that when people need to dig a long, deep hole, they call it a trench.
