Note
One spelling serves as the simple past (the climb exhausted us) and as the past participle after have or be (we had exhausted every option). The verb also covers the technical meanings of exhaust, such as drawing every soluble substance out of a material with solvents. When the form can be compared, more exhausted or most exhausted, it has become an adjective, as in the "very tired" meaning.

1791, James Boswell, Life of JohnsonNote
A laboratory use that has not survived: the word described a vessel, not a person or a supply. James Boswell's Life of Johnson (1791) records that a man "can live in thick air, but perishes in an exhausted receiver." Because the sense is obsolete, a modern reader will hear the "used up" meaning in such a line, so it is one to recognize in older scientific prose, not to use.
