The word exhausts is derived from the Latin word exhaustus, which is the past participle of the verb exhaustare. Exhaustare is a combination of the Latin prefix ex, meaning out, and haustus, the past participle of haurire meaning to draw out or to drain. When brought together, these components give exhaustus, which means drained out or become empty. Over time, the word was adopted into Middle English as exhausten, and it has since evolved into its current form, exhausts.
