"Variant of Umm"
The name Oumou is commonly a female name from the "Latin" origin.
Oumou is a West African name used in Senegal, Mali and Guinea, in Fula, Wolof and Bambara speaking communities. It corresponds to the Arabic element umm, meaning mother, and it appears in the compound name Oumou Kalsoum, the West African form of Umm Kulthum. In this reading Oumou is a regional form of an established Arabic name element rather than a modern invention.
Umm means "Mother".
The pronunciation of Oumou is OO-moo.
