What is exhausted?

When you use something up completely until it is gone, we say it has become exhausted.

Imagine your favorite tube of toothpaste. At first, it is full and squishy with plenty left for tomorrow’s brush. But after weeks of squeezing, the tube becomes flat, crinkly, and empty. You cannot get any more paste out no matter how hard you try. That tube is now exhausted. It has run out of its fuel or supply.

Exhaustion happens to people too, not just things like toothpaste or gas in a car. Think about playing outside on a hot day. You start with lots of energy, running and jumping around. But soon, your legs feel heavy, your breathing gets fast, and you just want to sit down. Your body has used up its available energy stores for that moment. It is exhausted.

This word often describes natural resources as well. Imagine a forest with lots of tall trees. If people cut down every single tree and do not plant any new ones, the forest no longer has wood to give. The resource is exhausted. It is not necessarily destroyed forever, but it is currently empty or used up for that specific purpose.

So, whether it is the last cookie in the jar, your energy after running a race, or oil deep underground, if there is nothing left to use right now, you can confidently say that thing is exhausted. It has been fully depleted of its power or supply.
