James (1998) classified the Hyam dialects according to the following sub-groups he placed under the Ham or Northern Group of the Proto-Plateau Ethno-Linguistic Cluster: • Ham Kpop (Jaban Kwoi) • Ham Ngat Ham (Jaban Katari) • Ham Shambang (Samban) • Ham Duhyah (or
Idun) (Jaban Lungu) • Ham Kworri (
Chori) • Ham Det (Faik/Kenyi) • Ham Netkun/Netwho (Gbaham) • Ham Nyakpah (or
Nyankpa) (Yeskwa) • Ham Kong/Rhuini (Kamantan) According to Hayab (2016:5-11), however, the Ham people, aside migratory past, a subject requiring keen study, could be said to speak the following: • Hyam Taa Ham - 'Hyam spread in Ham area' including
Nok, Ghikyaar, Kuscum, Har Dzyee,
Zhek, Shong, etc. • Kwyeny - same as James's Hyam Kpop (spoken in
Har Kwain or
Kwoi) • Kyoli - the dialect of the Kworri/Kwori (also known as
Chori) • Saik • Shamang - same as Shambang Hayab (2016:6) added that other varieties may also include: • Dùya/Idúyà - same as
Idun • Gwora - Gora • Yat •
Zhire - Kenyi. Further more, Hayab (2016:8) classified these dialects into four clusters, A-D, according to their levels of intelligibility. • Cluster A.
Hyam Taa,
Kwyeny, and
Saik (all have not less than 90% phonological homogeneity in vocabulary • Cluster B.
Kyoli and
Shamang (have about 50% intelligibility) • Cluster C.
Yat and
Zhire (may be coherent with A and B. More studies needed) • Cluster D.
Idúyà [or
Idun ] and
Gwora (stand in an independent category) Again note that Hyam is the language spoken by the Ham people. Blench (2019) lists: • Kwyeny • Yaat • Saik • Dzar • Hyam of Nok ==Orthography==
