Etymology: Parosmia is a medical term built from two Greek-derived pieces: "para-", meaning abnormal or deviant, and "-osmia", a suffix used for conditions of the sense of smell. Put together, the word describes a smell sense that has gone off course, not one that has disappeared. That distinction matters, because the condition is often misunderstood as simple loss of smell, which is a separate problem called anosmia. The "-osmia" ending comes from the Greek "osme", meaning smell, and it appears in other clinical terms about the nose, such as hyperosmia for an unusually sharp sense of smell. Doctors and scientists assembled these words from classical building blocks, so the term is a modern technical coinage rather than something ancient physicians used. Its logic is transparent: the prefix tells you what has happened to the smell, and the suffix tells you which sense is involved.
