Like Turkish, Fanagalo is characterized by certain amount of vowel harmony, wherein a vowel in a prefix is changed according to the subsequent vowel. In the Nguni tongues, the prefix "Mu-" or "Ma-" denotes the singular, while "Bu-" or "Ba-" signifies the plural – hence "Muntu" = a man; "Bantu" = men, particularly when applied to tribes, e.g. "Ma-tabele". Similarly, the prefix "Chi-" or "Si-" indicates the language spoke by that tribe. e.g. men of the "Lozi" tribe are called "Ba-rotse" (spelling is not standardized), and they speak "Si-lozi"; Bembas speak Chiwemba; Tswanas live in Botswana, formerly called Bechuanaland.
