What does exhausted mean?
Exhausted is an adjective describing a state of complete depletion — most often the profound tiredness felt after intense physical or mental effort, as when a nurse finishes a twelve-hour shift or a student emerges from an all-night study session. It can also describe non-living things: a supply, fund, or resource is exhausted once it has been entirely consumed and nothing remains. The word carries a stronger connotation than simple 'tiredness'; it implies that energy has been fully drawn out rather than merely reduced, which makes it a natural choice for dramatic or emphatic contexts. Derived from the Latin verb exhaurire, meaning 'to draw out' or 'to drain', it entered English in the early seventeenth century and has since become one of the most versatile intensity words in everyday English, appearing everywhere from casual conversation to medical literature describing fatigue.
Drained of physical or mental energy; very tired. Also: (of supplies or resources) completely used up.
"She collapsed onto the sofa, exhausted after the long journey."
When applied to things rather than people, it usually appears in formal contexts such as finance or logistics.
Past tense and past participle of the verb 'to exhaust': to use up completely or to tire someone out entirely.
"They exhausted every option before accepting defeat."
In this form it functions as part of a verb phrase rather than standing alone as an adjective.
The word 'exhausted' literally carries 'drawing out' in its DNA — from Latin exhaurire, 'to drain dry', the same root that gave us 'hectare' of all things through the idea of measured-out land.

Etymology of exhausted
Exhausted derives from the Latin exhaurire, formed from ex- ('out') and haurire ('to draw, drain'), literally meaning 'to drain out'. The verb exhaust entered English in the early seventeenth century, and its past participle exhausted came to function both as a verb form and as an adjective describing depletion of energy or resources. Cognates sharing the root haurire include exhaustion and exhaustive within English, reflecting the same underlying idea of drawing something out or using it up.
