Effie is the Scottish and English diminutive of Euphemia — from the Greek eu (good) and phēmē (speech, fame) — meaning "well-spoken" or "fair fame."
Effie Trinket in The Hunger Games brought the name to a new generation. Effie Brown (American film producer) and Effie Gray (the Victorian-era figure painted by Millais) are notable bearers.
Effie reduces to seven — the number of small bright fame.
