The Sawabantu languages are a clade of Bantu languages coded Zone A.20–30 or perhaps A.10–30 in Guthrie's classification. According to Nurse & Philippson (2003), the A.20 and A.30 languages apart from Bube form a valid node. They are:

(A.20) Duala

. For example, speakers of Limba (A.26), report some degree of mutual comprehension with Batanga (A.32) which they call "old Malimba" .

In addition, the (A.10) languages apart from the Manenguba

 cluster may also belong, but this is uncertain as they are poorly documented:

(A.10) Oroko

Oroko language

Oroko, or Bakundu-Balue, is a poorly known Bantu language spoken in Cameroon.Dialects are Kundu/Nkundu , Lue , Mbonge, Ekombe, Londo, Ngolo , Bima, Tanga , and Koko ....

. According to Lisa and Dan Friesen : "Despite the geographical proximity and linguistic classification of these groups, Oroko actually seems to share more similarities with A.20 languages like Duala (Jacquot and Richardson 1956:20-23, Richardson 1955:7-28)" . Oroko dialects seem to be particularily close to Kpwe

Kpwe language

Kpwe is a Bantu language of Cameroon. It is mutually intelligible with Kole, and probably with Mboko as well.There are multiple variants of the name: based on 'Kpwe' , on 'Kpe' , on 'Kweɾi' , as well as Ujuwa, Vambeng....
