The Herero consonant inventory includes prenasalized stops (mb, nd, ng, nj, nk, ny) and uniquely labialized prenasalized stops (mbw, ngw, nkw) — three-element phonemes where nasal, stop, and lip rounding fuse into a single sound. No click consonants are used, despite proximity to Khoisan-speaking communities in Namibia [2].
Herero has five vowel qualities (a, e, i, o, u) with contrastive vowel length. Long vowels are phonemically distinct from short vowels. The language has a two-tone system that is not written in the standard orthography. The five-vowel system is universal across the Bantu family [2].
Herero numerals 1–10 show prenasalized consonants prominently: mbari (two), ndatu (three), mbane (four), ndano (five). These forms differ substantially from East African Bantu numerals, reflecting Herero's Southwestern Bantu classification. The root omangunda (ten) carries the oma- noun-class prefix [1].
The complete Herero Latin alphabet includes standard letters plus digraphs and trigraphs for prenasalized stops (mb, nd, ng, nj, nk, ny) and labialized prenasalized stops (mbw, ngw, nkw). No click letters appear — unlike the Nguni Bantu languages (Zulu, Xhosa) whose ancestors absorbed click phonemes through Khoisan contact [2].
