"Fluorrheumin" is a rare medical term used to describe excessive and frequent discharge of mucus from the nose, throat, and sinuses due to inflammation caused by exposure to fluoride. The word is spelled phonetically as "fluōrhēūmin" [fluɔːɹhiːjumɪn], with its origins in Latin and Greek. The "fluo-" prefix indicates "flowing" or "flow," and "-rheumin" comes from the Greek word rheuma, meaning "flow." The spelling emphasizes the long vowels, the "r" sound, and the last syllable's emphasis.
