Reconstruction:Proto-Bantu/ngàdí

Evidently a Bantu innovation, as no cognates outside of Narrow Bantu are known.

*ngàdí class 9 (plural *ngàdí class 10)[1]

1. palm nut or palm oil (exact referent uncertain)

The sense "blood" (likely in class 6) may be an innovation in Proto-Eastern Bantu; the proposed semantic motivation is the reddish colour of palm oil, which would be an ideal target for taboo replacement of an earlier word for "blood".
