F Heavy

Effie is the old-fashioned short form for Euphemia. It shares a vintage charm with Hattie and Letty although is much rarer than either. Effie is a character in The Hunger Games and Sisterhood of the Traveling Pants.

Fifi is a perfect name -- for a French poodle. But Fifi may seem more child-friendly as names like Coco and Lulu rise. Fifi in its fluffiness also balances the seriousness of such full names as Josephine or Federica.

Also spelled Fyfe, this zippy sounding name would make a great middle name choice for music lovers or those with Scottish roots. The name has a double meaning: it is both a Scottish place name, likely derived from fiamh meaning "path", and also the name of an instrument, which takes its name from the German Pfeife and the French fifre meaning "pipe".

Variant spelling of Fife, borne by English musician Fyfe Dangerfield and Scottish journalist and reporter Fyfe Robertson.
