Etymology: Hypofunctioning is a straightforward formation: "hypo-" from Greek "hypo", meaning "under" or "below", attached to "functioning", the present participle of "function". The prefix is a classical element that English scientists and physicians used widely from the 19th century onward, and "hypofunctioning" follows the same pattern as "hypoactive" and "hypothyroid". "Function" itself came into English in the 1600s from Latin "functio", meaning "performance" or "execution", from "fungi", to perform. The term describes an organ, gland, or system working below its normal level, and it is most often used in medicine.
