Where do Central Cushitic ejectives come from?

This paper examines and accounts for the origin and presence of ejectives in Central Cushitic (CC) languages. Appleyard (2006) claimed that most occurrences of ejectives are due to borrowing from the Ethiosemitic languages. This is certainly true for all ejectives in Kemantney, and some in Blin and Xamtanga. However, examination of Appleyard’s data shows that only 37% of ejectives in Blin and 25% of ejectives in Xamtanga are found in borrowings. Most ejectives in CC in these two languages are therefore “of indubitable Agaw origin”, which suggests that ejectives are from the proto-language rather than through sound change. This paper analyzes the distribution of ejectives in Appleyard’s data and re-examines the consequences for reconstructed forms and probable sound changes.
