Etymology: Ariboflavinosis is a medical term built from modern scientific parts rather than ancient ones. Its core is "riboflavin," the name of vitamin B2, which itself combines "ribose," the sugar that forms part of the molecule, with "flavin," from Latin "flavus," meaning yellow, since the vitamin is a bright yellow pigment. Attaching the Greek-derived prefix "a-," meaning "without," and the suffix "-osis," used for abnormal or diseased conditions, produces a name for the disease caused by lacking riboflavin. The compound is a straightforward example of modern medical coinage. Riboflavin was isolated and named in the 1930s, so the disease name could only have been created after that, drawing on classical building blocks to describe a deficiency no ancient physician could have identified. Its parts therefore carry the history of the vitamin's discovery: a sugar, a yellow dye, and a Greek negative, combined to name an absence.
