Order of birth
Many African tribes name their children based on the order in which they are born, especially if a family has a lot of children. In Ghana, there are names such as “Esoun” and “Awotwe” given to children indicate that they are the seventh and eighth born respectively.
For twins, the Yorubas call the first twin “Taiwo” meaning “taste the world” and the second “Kehinde” meaning “came after”. In Ghana, the unisex names “Kakra” and “Panyin”, which mean younger and older, are used for twins.
This also exists in Uganda with “Kakuru” or “Wasswa” meaning elder twin and “Kato” for the younger one.
