Etymology: "Oxider" is an agent-noun built from the verb "oxide," which itself was formed from "oxygen" and the chemical suffix "-ide," so the word is a coinage of early nineteenth-century chemistry. Oxygen was named by Antoine Lavoisier in the 1777 era, from Greek "oxys" (sharp, acid) and "-gen" (producing), because he believed oxygen was the essential component of acids. The suffix "-ide" was adapted in the early 1800s from "oxide," and the "-er" ending marks something that performs an action, here adding oxygen to a substance. Because "oxider" describes a function rather than a substance, it appears mostly in technical and older chemical writing, where it names a reagent or process agent that oxidizes other materials. Chemists today more often use "oxidizer" or "oxidant" for the same idea, so "oxider" is now a rare variant rather than a standard term.
