Mesaka, or UgarÃÂ, is a Tivoid language spoken in Cameroon.
Batomo may be a separate language, or it may be the same as Motomo (Oliti, Matchi), a dialect of Iceve-Maci (Ethnologue, 22nd edition).
Vowel length is often contrastive in sequences of two similar vowels. Sequences of dissimilar vowels are not observed unless there's a consonant in-between.
Mesaka is also a tonal language with two tones: high and low.
