Definition of exhaustion

The word "exhaustion" has its roots in Latin. It comes from the verb "exhaustus", which means "to drain" or "to use up". This Latin verb is derived from "ex" meaning "out" or "from" and "haustus" meaning "having been poured out". This refers to the idea of something being drained or depleted of its energy or resources. The Latin verb "exhaustus" entered Middle English as "exhaust", and its noun form "exhaustion" emerged in the 15th century. Initially, it referred to the state of being drained or depleted, often physically or mentally. Over time, the term expanded to include emotional and psychological exhaustion, as well as exhaustion resulting from prolonged physical activity. Today, "exhaustion" is widely used to describe feelings of complete physical or mental depletion, often accompanied by fatigue, lethargy, and a general lack of energy.
