Root Explanation

Fluorouracil is formed from "fluoro-" (from Latin "fluor", meaning to flow or a flowing substance, often used in chemistry to denote the presence of fluorine) and "uracil" (a pyrimidine nucleobase found in RNA, derived from the combination of "uracil" which comes from "uracil" itself, meaning a component of RNA). The word refers to a compound that includes fluorine and is related to uracil, used primarily in cancer treatment as a chemotherapy agent.

Memory Tip

Think of 'fluoro-' as relating to a 'flowing substance' and 'uracil' as a part of RNA — together, they form a compound that flows in the body to target cancer cells.
