Etymology: "Desulfurised" is the British spelling of "desulfurized," the past tense and past participle of the verb "desulfurise." The verb is built from "de-," a prefix meaning "removal of" (from Latin "de," "away from" or "down"), attached to "sulfur," the element whose name came into English through Latin "sulfur" from an earlier Indo-European root associated with burning. Put together, the word literally describes having the sulfur taken away. The "-ise" ending is the standard British form of a verb suffix that turns nouns and adjectives into verbs, here applied to the chemical noun "sulfur." The corresponding American spelling uses "-ize," and both are equally recognized in dictionaries. The process it names is specific to industrial chemistry, where sulfur is stripped from crude oil, natural gas, or metals, so the term came into use alongside those industries rather than as an older everyday word.
