Yiwom language

Yiwom (Ywom), also known as Gerka or Gerkawa by the Hausa, is a Chadic (Afro-Asiatic) language spoken in Plateau State, Nigeria.

Sociolinguistic background
Ywom was formerly much more widespread, with Ywom toponyms found in southern Tarok-speaking areas. Roger Blench (2013) reports that Ywom is spoken in Hyel Ywom town and nearby hamlets. Many Ywom speak Jukun and Tarok as additional languages. Due to influence from Plateau languages, Ywom has various phonological features that are considered unusual for a West Chadic language, such as labiovelar consonants.
