Etymology: Derived from the Ancient Greek 'euphrosyne' (εὐφροσύνη), meaning 'joy' or 'mirth', itself from 'eu' (good) and 'phrēn' (mind or spirit). The name was associated with one of the Charites (Graces) in Greek mythology and later adopted as a saint's name. The plant genus Euphrasia was named for its traditional use in treating eye ailments, believed to bring 'brightness' or 'joy' to the eyes.
