Notes :The Sandawe form is quite compatible with Khoe and Peripheral Khoisan reflexes, through secondary click formation: *ƛ̣VḳVmV > *ƛkVmV > *||VmV, etc. The status of the Hadza form is less clear. Peripheral Khoisan forms are clearly not borrowed from Khoe (different semantics and phonetics).
Notes :A very tentative parallel (the function of the uvular efflux in Khoe is not understood), but possibly illustrating the process of secondary click formation in Khoe.
Notes :This is a rather forced parallel; the Hadza word is more easily comparable to certain Omotic forms, Khoe *mâ may be indicative of Niger-Congo substrate (several Khoe roots in *m- have good correlates in Niger-Congo, but not in other Khoisan languages), and labialization in the Peripheral Khoisan word may be due to some old vocalic peculiarities. Nevertheless, for lack of certainty, we leave the comparison as it is for now.
Notes :See Ehret 1986: 123. The Sandawe and Hadza forms may give a clue as to why the reflexes of this root in Bushman sometimes feature a labial click. The entire root is a perfect illustration of secondary click-forming mechanisms in Khoisan languages.
