No conclusive, methodologically sound basis for assigning Central Sudanic to an alleged full or partial Nilo-Saharan has been presented Blench, Roger 2000 , Bender, Lionel M. 2000 , Pascal Boyeldieu 2011 Tom Güldemann 2018: 294-309 . The parallels adduced by Gerrit J. Dimmendaal 2018 have been selected from various modern languages and have an alternative explanation as chance resemblances until shown to be reconstructable in the various microgroups. Although not included in the Central Sudanic comparison by Boyeldieu, Pascal 2010 , Boyeldieu, Pascal 2020 , Birri is very likely a Central Sudanic language in the light of the comparisons by Vorbichler, Anton 1969 (I wish to thank Roger Blench, Don Killian and Tom Güldemann for insisting on the strong parallels between Birri and Central Sudanic). The Kresh-Aja group has not yet been shown to be bona fide Central Sudanic Boyeldieu, Pascal 2010 , Boyeldieu, Pascal 2020 . In particular, the pronominal resemblances involving nasals in various constellations Tom Güldemann 2017: 119-122 Tom Güldemann 2018: 268-269 have only a weak probative value Harald Hammarström 2013 .
