Etymology: Ozostomia is a medical coinage, not an ancient word: it was built in the 19th century from two Greek elements. "Ozein" means "to smell" (the source of "ozone," which is named for its pungent smell), and "stoma" means "mouth," the same root found in "stomach" and "stomatology." Put together, the compound literally means "mouth-smelling," and it was used in medical writing to describe persistent bad breath as a clinical condition rather than a passing nuisance. Because the term was assembled deliberately from classical roots, it follows the same pattern as many other medical words of its era, where physicians combined Greek pieces to name a condition precisely. Its exact first recorded date and author are not something I can confirm, so the best way to date it is simply to say that it belongs to the broader wave of 19th-century clinical vocabulary.
