Notes :The correspondence "PNK *!̯ - Proto-!Wi *! (?) - ǂHoan ʘ" is not quite clear, but the problem of labial clicks can still hardly be called solved, and since forms like Zhu !xúí, ǀXam !khwi, and ǂHoan ʘxui perfectly match each other in all but the click influx, the etymology will be considered valid for the time being.
