Where did the word fatigue come from?

The Word "fatigue" originates from the Latin Word "fatigare," meaning "to tire out" or "to weary." It entered the English language in the early 15th century, initially used in a military context to describe the exhaustion of soldiers. Over time, its usage expanded to encompass general tiredness or exhaustion from various activities. Today, "fatigue" describes both physical and mental states of weariness.
