Proto-Chadic language
Quick Summary
Proto-Chadic is a hypothetical ancestral language from which the Chadic languages are believed to have descended. The Chadic languages form a subfamily within the larger Afro-Asiatic language family. These languages are spoken primarily in parts of Niger, Nigeria, Cameroon, and Chad.123
While Proto-Chadic itself is not directly attested, linguists reconstruct its features by comparing its daughter languages. These languages share characteristics such as specific consonant inventories, including glottalized and prenasalized consonants, and tonal systems used to distinguish word meanings. Many Chadic languages also exhibit a "root and pattern" morphological system, where consonants convey the core meaning and vowels modify it grammatically.13
