The Luvale consonant inventory includes a full series of prenasalized stops (mb, nd, ng, nj), labialized consonants (kw, gw, mw, nw), the palatal nasal ny (/ɲ/), and the retroflex or lateral sounds present in its Central Bantu neighbours. These prenasalized consonants — single phonemes, not two-consonant clusters — are a defining feature of the Bantu language family [3].
Luvale has five vowel qualities (a, e, i, o, u) with phonemically contrastive vowel length and a two-tone system (high and low). Long vowels can be represented by doubling the vowel letter (aa, ee, ii, oo, uu). Tones are lexically significant but are not marked in the standard orthography used in Zambia and Angola [3].
Luvale numerals 1–10 illustrate the Bantu additive counting pattern from five: yitanu na mono (six), yitanu na wari (seven), yitanu na tatu (eight). The root for ten — likumi — is cognate with Swahili kumi, Tumbuka khumi, and Zulu ishumi, tracing to Proto-Bantu *-kúmì [2].
The complete Luvale Latin alphabet includes standard letters plus digraphs for prenasalized stops (mb, nd, ng, nj) and labialized consonants (kw, gw, mw, nw). Each digraph represents a single phoneme — the letters work together to capture one sound, not two consecutive sounds [3].
