Meaning & Origin of Millie

Millie began as an affectionate diminutive of names such as Millicent, Mildred, and, in more recent decades, Amelia and Emily. Millicent derives from the Germanic elements "amal" (work) and "swinth" (strength), while Mildred combines "milde" (gentle) and "þryð" (strength) — both giving Millie an underlying sense of gentle power. The name was widely used as an independent name in the Victorian era, fell out of fashion through the mid-20th century, and has enjoyed a strong vintage revival in the 21st century, especially in the United Kingdom and Australia. Its warm, cheerful sound fits the current wave of short, old-fashioned nickname-names.
