Afrikaans phonology

In some instances of the postvocalic sequence /ns/, /n/ is realized as nasalisation (and lengthening, if the vowel is short) of the preceding monophthong, which is stronger in some speakers than others, but there also are speakers retaining [n] as well as the original length of the preceding vowel.

[29] Collins & Mees (2003) analyze the pre-/s/ sequences /an, ɛn, ɔn/ as phonemic short vowels /ɑ̃, ɛ̃, ɔ̃/ and note that this process of nasalising the vowel and deleting the nasal occurs in many dialects of Dutch as well, such as The Hague dialect.

[44] In diminutives ending in /ki/ formed to monosyllabic nouns, the vowels /u, ɪə, ʊə, ɛ, ə, œ, ɔ, a, ɑː/ are realised as closing diphthongs [ui, ei, oi, ɛi, əi, œi, ɔi, ai, ɑːi].

In the same environment, the sequences /ɛn, ən, œn, ɔn, an/ are realized as [ɛiɲ, əiɲ, œiɲ, ɔiɲ, aiɲ], i.e. as closing diphthongs followed by palatal nasal.

This change is especially prevalent among younger and female speakers, and it is attributed to prolonged contacts with Khoisan and Bantu languages.
