/t/ and /d/ are dentalized when followed by a front vowel /i/. An /s/ sound can only occur in loanwords.
Tones
Kwanyama has two tones : high and low.
Verbs are inflected for two tenses: present and non-present. There is a mandatory subject concord before verbs, indicating person, tense, and negation. Verbs are divided into two categories, active and stative, each of which have different subject concords. The future tense in active verbs is indicated by inserting the auxiliary ka after the nonpast subject concord.
Another way to negate a verb is to add the prefix ha- before the verb stem (ex. okwiimba 'to sing' -> okuhaimba 'to not sing').3
