Etymology
The word 'exhaust' originates from the Latin verb exhaurire, which is a compound of ex- ("out") and haurire ("to draw, drain"). Its literal sense was "to draw out or drain completely," as in draining a liquid from a vessel. This concrete meaning evolved metaphorically into the modern senses of using up resources entirely or draining someone of their energy. The noun form, referring to expelled gases, is a direct application of this "drawn out" concept, describing the byproducts drained from an engine.
