Effy
A girl's name of Greek origin with 83 recorded U.S. births.
Meaning & Origin
Effy peaked during the Gen Alpha era, when 14 babies received this name in a single year (2023). That era was defined by creative, boundary-pushing naming, and Effy remains in active use today — a name that has outlasted its original moment.
In the most recent SSA release, Effy ranks #11334 among U.S. girl names — distinctive enough to stand out.
Effy is a girl's baby name of Greek origin, a diminutive of Euphemia — from the Greek meaning 'well-spoken,' 'auspicious speech,' or 'speaking well of.' Saint Euphemia of Chalcedon was one of the earliest Christian martyrs. Effy was also a popular nickname for Euphemia in Scotland and Ireland.
Rare and charming, Effy gained modern visibility through the character Effy Stonem in the British drama series Skins — bringing this vintage diminutive to a new generation of admirers.
