52 main distinctions between the two that Bari-Latuko-Dongotono in certain points of grammar (e.g. the distinction of gender) show Hamitic features.

Groups IV and V are of a different character; they resemble in many of their features the West African type, especially the Kwa group of Western Sudanic languages. Many of the word stems are monosyllabic, consisting of one consonant and one vowel, whereas in the Nilotic Group consonantal ending is the rule. Words are distinguished by tone, e.g. in Madi tz with a low tone means “ mouth”, and with a high tone ‘‘cow”. In the genitive case the possessor precedes the thing or person possessed. The sounds gp and kp are of frequent occurrence.
