Etymology: "Desulphured" is the past tense and past participle of "desulphur," a verb meaning to remove sulfur from a substance. The word is built from "de-," a prefix meaning "removal" or "reversal," attached to "sulphur," the English form of the Latin "sulphur," which is itself a term with ancient roots in the element's yellow, flammable solid form. Adding "de-" to a noun for a substance to create a verb for taking that substance away is a common pattern in chemistry and industry, which is why the word reads so transparently. The "-ed" ending marks the past tense and participle, so the adjective use, as in "desulphured fuel," simply describes material that has already been treated. Because the formation is so straightforward, the word's meaning follows directly from its parts, and no special story sits behind it beyond the ordinary chemical vocabulary built on "sulphur."
