Phonology
The sound system of Sotho is unusual in many respects. It has ejective consonants, click consonants, a uvular trill, a relatively large number of affricate consonants, no prenasalised consonants, and a rare form of vowel-height (alternatively, advanced tongue root) harmony. In total, the language contains some 39 consonantal and 9 vowel phonemes.
It also has a large number of complex sound transformations which often change the phones of words due to the influence of other (sometimes invisible) sounds.
