Appendix:Proto-Niger-Congo numerals

Below is a comparison of Proto-Niger-Congo numerals and supporting reconstructions in lower-level Niger-Congo branches, many of which are tentative branch reconstructions by Tom Güldemann (2018: 142-145) and Pozdniakov (2018).

Overview
The numerals are ‘two’, ‘three’, ‘four’, and ‘five’. Güldemann (2018: 147) reconstructs these forms for the numerals 2-5 in Proto-Niger-Congo.


 * *Ri ‘two’
 * *ta(C) ‘three’
 * *na(C) ‘four’
 * *nU ‘five’

However, Pozdniakov (2018: 293) reconstructs:

Other lexemes used by Güldemann (2018) as Niger-Congo diagnostic forms (i.e., to determine whether or not a language should be classified as Niger-Congo) are:


 * ‘person/people’
 * ‘tongue’
 * noun class *1 prefix for human singular
 * noun class *2 prefix for human plural
 * noun class *6A prefix for liquid and mass nouns ("uncountables")
 * the first and second person pronouns (both singular and plural); Güldemann's (2018) Proto-Niger-Congo pronoun reconstructions are below:
