Effrosyni

Lively and cheerful, Effrosyni is the modern Greek form of the ancient Euphrosyne. Its meaning is interpreted as "mirth and merriment" from the elements eu meaning "good" and phren meaning "mind, heart". In Greek mythology, Euphrosyne is one of the three Graces.
In its modern form, it is notably borne by author Effrosyni Moschoudi, volleyball player Effrosyni Sfyri, and synchronized swimmer Effrosyni Gouda. Historically, it is associated with the 5th-century Saint, St Osia Effrosyni, who lived as a monk to avoid marriage and is celebrated by the Orthodox church for her dedication to helping the poor and to Divine Love.

Common Greek nicknames for Effrosyni include Efi (Effie) and Froso.
