"Variant of Abd"
The name Abdou is commonly a male name from the "Muslim" origin.
Abdou is a short form, used as a given name in North Africa and in French-speaking West Africa, of Arabic compound names that begin with the element ʿabd, "servant", such as Abdoulaye, Abdourahmane and Abdelkader. The -ou spelling reflects French transliteration of the Arabic long vowel. It is not a separate root name but a clipped, familiar form of those compounds.
Abd means "Variant of 'Abd: Slave. Servant.".
The pronunciation of Abdou is AB-doo.
