What does exhaustible mean?
"Exhaustible" is an adjective describing anything capable of being completely used up — a resource, a supply, or even an abstract quality such as patience or goodwill. It is the direct opposite of "inexhaustible," which denotes something that can never be depleted. In everyday and formal usage alike, "exhaustible" appears most often in discussions of natural resources: fossil fuels, minerals, and other materials that cannot regenerate on human timescales. Environmental science, economics, and public policy frequently rely on this term to distinguish finite assets from renewable ones, as in "exhaustible versus renewable energy sources." The word also extends figuratively to personal reserves — one's energy or tolerance can be described as exhaustible when it will eventually run out under sustained pressure. Derived from the Latin exhaurire, meaning to drain or draw out entirely, "exhaustible" carries a neutral, descriptive tone rather than an emotional one; its force lies in the implicit warning that whatever it describes has a hard limit and will eventually be gone.
Capable of being used up completely; not able to be renewed or replaced once depleted.
"Natural gas is an exhaustible resource, unlike solar power."
Most frequently applied to natural resources in economic and environmental contexts.
(Of abstract reserves such as patience or energy) capable of being worn out or depleted.
"Her goodwill was exhaustible after years of unreturned favours."
Figurative use; less common than the literal sense.
The word 'exhaustible' comes from the Latin exhaurire, meaning 'to draw out' or 'to drain dry' — a vivid image of emptying a well to its last drop.

Etymology of exhaustible
"Exhaustible" derives from the Latin verb exhaurire, formed from ex- ('out') plus haurire ('to draw water, to drain'), meaning 'to draw out completely' or 'to drain dry.' It entered English in the 17th century via the past participle exhaustus, the same root that gave English 'exhaust,' 'exhaustion,' and 'exhaustive.' The suffix '-able' marks it as denoting capability — literally 'able to be drained.' Its antonym 'inexhaustible,' built with the negative prefix in-, appeared around the same period and remains equally common in modern English.
