What Does the Name Millie Mean?

Millie is an English diminutive that means 'gentle strength' when it shortens Mildred and 'strong in work' when it shortens Millicent. It has no independent root of its own; its meaning comes from the full name it shortens. Mildred derives from the Old English Mildþryð, made of milde ('gentle, mild') and þryð ('strength, power'), so its literal sense is 'gentle strength.' Millicent comes from the Old French Melisende, which in turn goes back to the Germanic name Amalasuintha, formed from amal ('work, labor') and swinþ ('strong'); its customary meaning is 'strong in work' or 'industrious.' Because Millie can stand for either name, both meanings are sometimes attached to it. In modern use Millie also appears as a short form of Amelia, Emily, and similar names, but those names have separate origins and are not the source of the usual explanations of Millie's meaning.

Millie Name History & Origins

Millie developed as a spoken short form of Mildred and Millicent before it became a given name in its own right. Mildred is an Old English name recorded as Mildþryð; it was borne by Saint Mildred, a 7th-century abbess of Minster in Thanet, and the name was known in medieval England through her cult. Millicent entered English through Old French Melisende, a form used in the medieval crusader states; Melisende was the name of a 12th-century queen of Jerusalem. In the 19th century, Millie was used as an independent given name, not only as a nickname. The name later appeared as the title character of the 1967 film Thoroughly Modern Millie and its later stage version, a literary and theatrical use rather than the name's origin. Millie is used as an independent given name in English-speaking countries.
