Reconstruction:Proto-Yoruboid/è-bye

Etymology
Almost certainly a locally derived root from Proto-Yoruboid. While most Niger-Congo or Volta-Niger languages usually have the 5+2 for seven, this is almost certainly developed from a different root that took on the meaning for seven. The innovation of distinct roots from 5-10 is a unique feature of Proto-Yoruboid and Yoruboid languages among most of the Atlantic-Congo branch.
