Etymology: "Biodegradation" is a plain modern compound, and its two halves come from different centuries and languages. The first part, "bio-", comes from Ancient Greek "bíos", meaning "life," which is the same root behind words like "biology." The second part, "degradation," comes from Latin "degradare," meaning "to lower in rank or status," built from "de-" (down) and "gradus" (step). So the word literally combines the Greek idea of life with a Latin idea of stepping something down. The Greek and Latin roots were not put together in antiquity. The compound was formed in English, using classical building blocks that were available to scientists and writers, and the "bio-" element became a productive prefix for coinages in modern science. Its meaning follows from its parts: the breakdown of material by living organisms, the step-down from complex matter to simpler forms.
