Etymology: "Defueled" is the past tense and past participle of "defuel," a verb formed in English by attaching the prefix "de-" to "fuel." The prefix comes from Latin, where "de-" carried senses of removal, reversal, or taking away, so "defuel" literally means to take fuel away from something. The base word "fuel" has its own older history, passing into English from Old French, where it descended from Late Latin "focale," meaning hearth, and ultimately from the Latin "focus," the fireplace at the center of a home. The result is a word whose core idea is a reversal of supply: where "fuel" means the material that feeds a fire or engine, "defuel" describes an object that has had that material removed, consumed, or exhausted. The prefix "de-" is productive in English and attaches readily to nouns and verbs of technical or practical use, which is why "defuel" could be formed as a straightforward coinage on an existing base rather than borrowed from another language.
