Notes :This morpheme functions as the 1st person pl. exclusive pronoun in most SK languages except for !Xóõ. Since external evidence shows that the NK opposition of *m vs. *e is more archaic, the use of *sV in that function in SK is probably innovative. It is therefore reasonable to compare it with NK *sa 'they two' (with the meaning shift 'they two' => 'me and him two' in SK). Whether this morpheme is related to Khoekhoe pronominal prefixes *sa- (excl.) or *si- (incl.) has yet to be established.
