Reconstruction:Proto-Yoruboid/ɛ̀-fà

Etymology
While most Yoruboid roots beyond five seem to be local innovations, not even sharing with cognates in other Volta-Niger languages, this seems strongly related to 🇨🇬, where /h/ to /f/ is a common phonological change often seen between Edoid and Yoruboid languages. The Edo form is also certainly related to 🇨🇬.
