Etymology: "Nonlipidemic" is a modern medical compound, built from three parts with older histories. The prefix "non-" comes from Latin "non," meaning "not," and simply negates what follows. The core, "lipidemic," combines "lipid" and "-emic." "Lipid" comes from Greek "lipos," meaning fat, and chemists apply it to fats and fat-like substances. The ending comes from Greek "haima," blood, which appears in English as "-emia" in words like "anemia." The adjectival "-emic" therefore describes blood carrying an elevated level of lipids. Ancient Greek and Latin speakers never used this combination. It was assembled from classical building blocks to name a clinical condition, and "nonlipidemic" then negates that condition to describe a person or sample without it.
