Blench (2006,[2] 2016[3]) proposes that Proto-Niger–Congo originated about 11-10,000 years before present in the western part of the "Green Sahara" of Africa (roughly the Sahel and southern Sahara), and that its dispersal can be correlated with the spread of the bow and arrow by migrating hunter-gatherers.
Proto-Niger–Congo is traditionally assumed to have had a disyllabic root structure similar to that of Proto-Bantu, namely (C)V-CVCV[6] (Williamson 2000,[7] etc.). However, Roger Blench (2016) proposes a trisyllabic (CVCVCV) syllabic structure for Proto-Niger–Congo roots,[6] while Konstantin Pozdniakov (2016) suggests that the main prototypical structure of Proto-Niger–Congo roots is *CVC, along with disyllabic, trisyllabic, and other variations.[8]
Konstantin Pozdniakov (2018) has published a detailed reconstruction of Proto-Niger–Congo numerals, as well as comprehensive reconstructions for the lower-order branches of the Niger–Congo phylum. Pozdniakov (2018: 293)[13] and Güldemann (2018: 147) reconstruct the following numerals for Proto-Niger–Congo.[1]
Numeral
Proto-Niger–Congo (Pozdniakov 2018)
Proto-Niger–Congo (Güldemann 2018)
1
*ku-(n)-di (> ni/-in), *do, *gbo/*kpo
2
*ba-di
*Ri
3
*tat / *tath
*ta(C)
4
*na(h)i
*na(C)
5
*tan, *nu(n)
*nU
6
5+1
7
5+2
8
*na(i)nai (< 4 reduplicated)
9
5+4
10
*pu / *fu
20
< ‘person’
The numerals 6-9 are formed by combining lower numerals, while ‘20’ is derived from ‘person’.
There is currently no comprehensive, systematic reconstruction for Proto-Niger–Congo lexical roots. Nevertheless, quasi-reconstructions (preliminary, tentative reconstructions, which are marked using the number sign #) have been attempted by Roger Blench, who is currently compiling a Niger–Congo etymological dictionary. Some examples from Blench (2016):[6]
Blench (2009) lists various Niger–Congo quasi-reconstructions for plants with important economic uses (note that not all of them necessarily reconstruct to Proto-Niger–Congo). These roots are generally widespread areal forms (Wanderworts), with some of them also found in Afroasiatic and Nilo-Saharan languages.[16] A few forms are also added from some of Blench's other works (2006, 2012, 2016).
Below are some quasi-reconstructions of Niger–Congo areal forms for animal names given by Blench (2007[19]), with some reconstructions also based on Blench (2006).[2]
