Phonology
Tsonga has a distinction between modal and breathy voiced consonants: /bʱ, bvʱ, vʱ, dʱ, ɖʐʱ, dʒʱ, ɡʱ/ vs /b, bv, v, d, ɖʐ, dʒ, ɡ/ among the obstruents (the one exception being /ɮ/), and /m̤, n̤, ŋ̈, r̤, ȷ̈, w̤/ vs /m, n, ŋ, r, j, w/ among the sonorants (the one exception being /ɲ/).
Unlike some of the Nguni languages, Tsonga has very few words with clicks, and these vary in place between dental and postalveolar.
