Etymology: Ageusia is a medical term for the loss or impairment of the sense of taste. It is built from three Greek parts: the negative prefix "a-" (meaning "without"), "geusis" (taste, from the verb "geuein" or "geuō", "to taste"), and the suffix "-ia", a common Greek ending for conditions and states. Put together, the word literally means "without taste," which is exactly what a doctor needs to describe when a patient can no longer detect sweet, salty, sour, bitter, or savory flavors. The stem "geusis" also gave English the word "gustatory," used for anything relating to taste, which makes ageusia a close relative of that more familiar term. Because the word is a deliberate construction from classical Greek parts, it reflects the modern habit of coining precise medical vocabulary from ancient roots rather than any everyday usage in antiquity.
