Stevie is the diminutive of Stephen or Stephanie — from the Greek stéphanos, meaning "crown" or "garland." Used as a girl's name in its own right since the 20th century.
Stevie Nicks (born 1948), the Fleetwood Mac singer and solo artist, is the most famous bearer. Today Stevie is rising fast as a girl's name — currently in the U.S. top 600 and climbing.
Stevie reduces to eight — the number of soft crowned authority.
