The West Chadic languages of the Afro-Asiatic family are spoken principally in Niger and Nigeria.

The branches of West Chadic go either by names or by letters and numbers in an outline format.

George Starostin's (2010) internal classification of West Chadic[6] as presented in Blažek (2010):[7] Roger Blench's (2021) internal classification of West Chadic:[8] Distributions of West Chadic branches:[9] Roger Blench (2022) suggests that West Chadic languages may have spread via a gradual agricultural dispersal in Central Nigeria, starting from 3,000–4,000 years ago.

Blench notes that West Chadic morphology has been heavily influenced by Plateau languages, likely as a result of long-term intermarriage that occurred as West Chadic incomers took local wives who spoke Plateau languages.

These consonants were borrowed from Plateau languages due to intensive long-term contact.
