In ancient Greek mythology, the name “Gorgon” most closely means “dreadful” in English.
The term comes from the ancient Greek word gorgos, meaning dreadful, grim, or terrible. It describes the frightening appearance and supernatural danger associated with the Gorgons. Medusa is the most famous member of the group, but the name properly applies to all three sisters: Medusa, Stheno, and Euryale.
The word is a description, not the personal name of Medusa. Modern readers sometimes use “Gorgon” as if it meant Medusa alone, especially because Medusa became the dominant figure in later art and popular culture. In ancient Greek art and literature, however, Gorgon imagery could represent a broader protective or terrifying monster type. The English word “gorgon” later developed additional figurative uses for a frightening woman or creature.
