The core is held together by regular sound correspondences in lexical items between subfamily languages, less systematic verbal extensions and noun class systems Stewart, John M. 2002 , Stewart, John M. 2005 , Pozdniakov, Konstantin Igorevich and Segerer, Guillaume 2004 , Hyman, Larry M. 2007 Tom Güldemann 2018: 154-174 , 177-179, 180-189, 194-199, 200-213, 213-223, 223-231, 232-234, 353-358.

Tom Güldemann 2018: 192-193 , 232-234, 353-358) have not yet been shown to stand up to these criteria wherefore they are excluded. The Pre or Mbre language in Côte d'Ivoire, known from wordlists only, is Atlantic-Congo but cannot be assigned to a specific branch at this time Blench, Roger 2006 , Boukari, Oumarou 2009 Tom Güldemann 2018: 180 . The Mpra (= Mpre) language in Ghana has cognates with Atlantic-Congo especially Guang Goody, Jack R. 1963 , including numerals 2-5, but the bulk of the little vocabulary that is known, is not Atlantic-Congo Blench, Roger 2012 . On the grounds that the numerals are less likely to be borrowed, and that lexical innovation may produce vocabulary that looks unrelated to anything else, we count Mpra as an Atlantic-Congo language. Aproumu Aizi [ahp]: Marchese, Lynell and Hook, Ann 1983 Ahaté, Tamala Louise 2018 does not seem to be a Kru language but, judging from the numerals, appears to be an Atlantic-Congo language (I wish to thank Roger Blench for highlighting the divergent nature of this language).
