What does exhausting mean?
Exhausting is an adjective used to describe something that leaves a person feeling drained of energy, whether through physical effort, mental strain, or emotional pressure. A marathon, a difficult exam, a demanding job interview, or even a tense argument can all be described as exhausting. The word carries a strongly negative connotation, emphasising depletion rather than mere tiredness, which makes it more forceful than milder alternatives like 'tiring'. It derives from the verb 'to exhaust', which traces back through Old French to the Latin exhaurire, meaning 'to draw out' or 'drain dry'. In modern usage it appears constantly in everyday speech — an exhausting day at work, an exhausting journey, an exhausting schedule — and it applies equally to literal exertion and figurative strain, allowing speakers to convey that something consumed their energy in body, mind, or spirit.
Causing extreme tiredness; draining of physical or mental strength.
"The exhausting climb to the summit took them nearly six hours."
Often intensified with words like 'utterly' or 'absolutely', and frequently used figuratively for emotional or mental strain as well as literal fatigue.
Present participle of 'to exhaust': to use up completely, or to tire someone greatly.
"The constant travel was exhausting her before she had even reached thirty."
As a verb form, it functions within continuous tenses and can also serve attributively, overlapping with its adjectival use.
It comes from Latin ex- + hauserе 'to draw out' — literally to draw everything out of you, down to the last drop.

Etymology of exhausting
The adjective exhausting derives from the verb 'exhaust', which entered English from French in the late 16th century, ultimately rooted in the Latin exhaurire ('to drain, draw out'), formed from ex- ('out') + haurire ('to draw water'). The participial adjective developed naturally from this verb, describing something that drains energy. It shares its root with other English words including exhaustion and exhaustive, though these have taken on distinct meanings over time.
