This is like asking, "What are your favourite European names?" It's difficult to answer, especially as I've never dedicated the time to looking through the list of names for every single African language, as I haven't with every single European language.
I did, however, inspired by Chimamanda
Ngozi Adichie's books, make a little list of my favourite Nigerian names.
