Reconstruction:Proto-Yoruboid/ù-kó

Etymology
Probably from. While most Yoruboid descendants continue to use the meaning "lip," in Northwest Yoruba speakers, the term has come to only refer to beak, with the form taking the meaning "lip." See 🇨🇬. Other Yoruboid descendants or related Volta-Niger languages usually have the form of "top of the mouth." A hypothetical reconstructed form, (which several Yoruboid languages have), could be a synonym for lip, however it is not clear if this is a Proto-Yoruboid form, though a potential descendant form is attested with the meaning "tongue," see 🇨🇬.
