Proto-Bushman : *ʒu(ʔ)ŋ (?)
Meaning : to nosebleed
Proto-Ju : *dũʔũ
Proto-Taa : *ʒâ̰ũ
Notes : Very dubious because the correspondence "PNK *d - PSK *ʒ" has not been attested anywhere else (so far), and vocalic correspondences are odd as well. However, it is still too early to dismiss it right out of hand.
