Saquinavir /sə-ˈkwi-nə-ˌvir/ noun 

Definition: Saquinavir is a medication used to treat the human immunodeficiency virus (HIV). It is part of a class of medications called protease inhibitors and works by decreasing the amount of HIV present in the blood. 

Saquinavir is not a cure for HIV, but it does lower the chance of developing related illnesses, such as acquired immunodeficiency syndrome (AIDS), cancer, and other serious illnesses. It is often used in combination with other antiretroviral agents to maximum efficacy.

Etymology: The name of this medication comes from a combination of related words. The sa- is likely used to reference protease. Next, -quin- comes from quinoline, a compound originally isolated from the Cinchona tree, which was originally used to treat malaria. The -vir ending is likely a reference to it being an antiviral drug.
