Boan languages

Boan (Buan, Ababuan) is a proposed intermediate group of Bantu languages coded Zones C and D in Guthrie's classification.[2] There are three branches:

• Komo (D20)
• Bali (D20), ?Beeke
• Bomokandian (the various Bwa and Biran languages)
  • Biran (Bira–Amba) (D22, D30)
  • Homa (Ngenda) (D40)
  • Lika (D20)
  • Bati–Angba (Bwa) (C40)

Boan
Ababuan
Geographic distribution	Democratic Republic of the Congo
Linguistic classification	Niger–Congo Atlantic–Congo Benue–Congo Southern Bantoid Bantu (Zones C–D) Boan
Subdivisions	Bati–Angba (Bwa) Komo–Bira
Glottolog	abab1240[1]

Beeke is an erstwhile member of the Nyali cluster that seems to be closest to Bali.

In the Glottolog 2.3 classification, several additional, poorly attested languages are included as being closest to Homa/Ngenda:

• Bali (D20)
• Old Bomokandian
  • Komoic (Biran, incl. Komo)
  • Middle Bomokandian (Lika & Bati–Angba)
  • Ngbele–Ngenda
    • Extreme-north Vestigial-suffix Bantu: Kari, Ngbee, Nyanga-li (Gbati-ri)
    • Ngendan
      • Homa, Ngbinda, ?Boguru, ?Bodo (perhaps instead Lebonya)
