While Millie has traditionally been used as a diminutive of the names Mildred and Millicent, this feminine moniker has become a favored stand-alone choice in its own right. From the Old English Mildþryð, Millie's confident sound is complemented by its meaning "gentle strength." The Germanic Millicent brings Millie to the next level with meanings like "unceasing strength," "vigorous strength," and "brave strength," which will no doubt inspire your kiddo to boldly achieve their dreams. The Bump member Happily Overwhelmed says: "In the old days, it was always short for Millicent (or Mildred)...but who says it has to be?" And we agree! Millie can be considered a nickname for names like Amelia, Camilla, Emily, Matilda, and more, opening it up to a world of possibilities.
