Millie
Meaning
pet form of Millicent/Amelia/Mildred
The story
Millie is a short form with four parents, which is unusual even here. Our verified short-form records tie it to Mildred, Amelia, Emilia and Emily, and those are not variants of each other: Mildred is Old English for gentle strength, while the Amelia and Emilia lines are Germanic and Roman respectively. Millie is the sound they all collapse into. Its curve is a clean vintage U. About 4,200 babies in the 1910s, a long fall to roughly 460 in the 1980s, and then a return to 6,900 in the 2010s and more than 14,200 so far this decade. It is now used almost entirely for girls, about 44,400 to 212. A family can reach Millie from four different long names or from none of them, and increasingly they choose it outright.
The formal names behind Millie
Millie is an established short form of each of these names.
Mildred · English origin · gentle strength
Emilia · Latin origin · traditionally "rival," from the Roman family name Aemilius; immortalized by Shakespeare's truth-telling Emilia of Othello
Emily · Latin origin · traditionally "rival," from the Roman family name Aemilius; Chaucer gave English its first Emily, and the 1990s gave it a very long run at #1 in America. Feminine without frills, with Em and Emmy for everyday
Amelia · Germanic origin · traditionally "work," from the old root amal that also gives Amalia; long entangled with the unrelated Latin Emilia. An 18th-century royal favorite revived worldwide, a full classic that answers to Amy, Millie, and Mia
Emelia · Germanic origin · variant of Amelia from the Germanic element amal, of uncertain meaning and possibly linked to the Amali dynasty or to 'unceasing, vigorous, brave'; unrelated to Emilia
Millicent · Germanic origin · strong in work
