Milli is of Latin origin and means "wisher." It is an alternative spelling of the name Millie, which itself is a diminutive form of Mildred. The name Milli was popularized in the late 20th century due to its use by several notable individuals, including Milli Vanilli, a German Eurodance duo from the late 1980s and early 1990s known for their chart-topping hits like "Girl You Know It's True" and "Blame It on the Rain." Today, Milli is still considered an uncommon yet charming choice for a girl's name.
"This name has seen a significant increase in popularity over the years, with a noticeable spike from 2008 onwards and a consistent rise since then."
