Kimbundu

Kimbundu, a Bantu language which has sometimes been called Mbundu or North Mbundu (to distinguish it from Umbundu, sometimes called South Mbundu), is the second-most-widely-spoken Bantu language in Angola.

Its speakers are concentrated in the north-west of the country, notably in the Luanda, Bengo, Malanje and the Cuanza Norte provinces. It is spoken by the Ambundu.

Consonants
Allophones:

[ɸ] and [β] are allophones of /p/ and /b/, respectively, before /a/ and /u/. The phoneme /l/ is phonetically a flap [ɾ], a voiced plosive [d] or its palatalized version [dʲ] when before the front high vowel /i/. In the same way, the alveolars /s/, /z/ and /n/ are palatalized to [ʃ], [ʒ] and [ɲ], respectively, before [i]. There may be an epenthesis of [g] after /ŋ/ in word medial positions, thus creating a phonetic cluster [ŋg] in a process of fortition.

There is long distance nasal harmony, in which /l/ is realized as [n] if the previous morphemes contain /m/ or /n/, but not prenasalized stops.

Vowels
There are two contrasting tones: a high (á) and a low tone (à). There is also a downstep in cases of tonal sandhi.

Vowel harmony
There is vowel harmony in two groups (the high vowels /i, u/ and the mid and low vowels /e, o, a/) that applies only for verbal morphology. In some morphemes, vowels may be consistently deleted to avoid a hiatus.

European Portuguese
There is a small number of words of Kimbundu origin and many of those are indirect loans, borrowed via Angolan Portuguese.

The examples generally understood by most or all speakers of Angolan and European Portuguese include

bué (, "very, a lot"),

cota (, "old person" )
