Swahili is presented as another East African Bantu language in which aspiration is distinctive in some dialects. In KiUnguja and KiMvita, aspirated consonants derive directly from Bantu prenasalized voiceless stops, making aspiration less functionally prominent than in Makhuwa. The distinction is not represented in standard orthography, although it has been recorded in descriptions of speech from Zanzibar and Mombasa.

The passage identifies KiMvita with Mombasa and KiUnguja with Zanzibar. In these varieties, aspiration may arise when a first-person singular morpheme precedes a voiceless consonant, and several dialects show aspiration shift from a later to an earlier consonant. The shift generally targets the stressed penultimate syllable, while further retraction is not observed in the examples discussed.

Swahili also shows evidence of deaspiration, although its direction differs from Makhuwa. In the relevant domain, aspiration shift and deaspiration together tend to preserve aspiration on the first suitable consonant, whereas Makhuwa preserves the last aspirated consonant. The passage further connects Swahili and Makhuwa through lexical borrowing, arguing that some Makhuwa forms with otherwise unexplained aspiration most likely entered from Swahili.
