Fatigued is a synonym of words like tired, exhausted, and weary—all words to describe a person who is out of energy. Fatigued describes a state in which you desperately want to sleep or rest. Fatigued comes from the noun fatigue, which means weariness or lethargy. If you are unfatigued, you are not fatigued, that is, you have energy.

Etymology
Origin of fatigued
Explanation
If you're fatigued, you're exhausted. You're bound to be fatigued after climbing a mountain — or babysitting for five year-old triplets. When you're so wiped out and tired that you can barely brush your teeth and fall into bed at night, you're truly fatigued. It's another way to say "tired," "exhausted," "beat," or "tuckered out." The adjective fatigued comes from fatigue, originally a French word meaning "weariness," from the verb fatiguer, "to tire," which has a Latin root, fatigare, "to make weary."
