exhaust

From Latin exhaustus, the past participle of exhaurīre, 'to draw out, drink up, empty,' itself built from ex ('out') plus haurīre ('to draw, especially water, or drain').

The facts given show only the Latin formation — 'to draw out' or 'drain completely' — carried directly into English as exhaust, without further recorded shifts.

It shares its root haurīre with exhauriō, the fuller Latin verb form meaning 'to draw out, drink up, empty' — the same drawing-out sense at the heart of exhaust.
