Etymology: The name "biotin" was coined in German, and its Greek root points to life rather than to any chemical property. "Biotin" comes from German, where it was formed from the Ancient Greek "bíotos", meaning "life", with the chemical suffix "-in" added. The name reflects the vitamin's role as an essential nutrient, something the body cannot do without. The suffix "-in" is the familiar ending used for many substances isolated in the 19th and early 20th centuries, so "biotin" follows the same pattern as words for other chemical compounds. The Greek element "bio-" is the same one found in "biology" and "biography", both of which trace back to "bíos" and "bíotos" in the same sense of life.
