Mangbai (Mamgbay, Mambai) is an Mbum language of northern Cameroon and southern Chad.

Distribution

In Cameroon, Mambay is spoken along the Mayo-Kebi River near the Chadian border, in the Djaloumé region (northern end of Bibemi commune, Bénoué department), where there is a massif called Hosséré Mambay. It is also spoken in the extreme southeast of Figuil commune, Mayo-Louti department. In Cameroon and Chad, there is a total of about 2,500 speakers, many of whom also speak Mundang.

^ The affricate [dʒ] and the prenasalized consonants [ᵐb ⁿd ᵑɡ] are found in loan words from Fula.
^ ^a ^b ^c ^d ^e ^f ^g ^h The bilabial /p b/ and velar /k ɡ/ plosives, as well as the labiodental /f v/ and alveolar /s z/ fricatives, only have a voiced–voiceless contrast in morpheme-initial position; elsewhere, the contrast is absent.
^ ^a ^b In syllable codas, medial and final positions, the bilabial plosives /p ~ b/ are realized as unreleased voiceless [p̚].
^ ^a ^b In syllable codas, medial and final positions, the alveolar plosives /t ~ d/ are realized as unreleased voiceless [t̚].
^ ^a ^b
When lacking voicing contrast, the velar plosives /k ~ ɡ/ are realized as:
- unreleased voiceless velar plosive [k̚] after front vowels in syllable codas, medial (in careful speech) and final positions
- unreleased voiceless uvular plosive [q̚] after back vowels in syllable codas, medial (in careful speech) and final positions
- voiced velar fricative [ɣ] after front vowels in medial position (in typical and fast speech)
- voiced uvular fricative [ʁ] after back vowels in medial position (in typical and fast speech)
^ ^a ^b The contrastive status of the glottal stop /ʔ/ as an independent consonant is uncertain.
^ ^a ^b The patterning of the glottal fricative /h/ is uncertain. When preceding long vowels, the semivowels /j w/ alternate with [h] in initial (both morpheme- and syllable-initial) positions.
^ ^a ^b The velar nasal /ŋ/ is realized as palatal [ɲ] after front vowels; however, if it is followed by a velar plosive /k g/, then its articulation remains velar. Anonby (2008)'s data did not include any examples of the preglottalized velar nasal /ˀŋ/ after front vowels, so a conclusion about its realizations was not made.
^
The alveolar /r/ is realized as:
- retroflex flap [ɽ] in initial and medial position
- alveolar trill [r] in syllable coda, and less commonly in initial position
^
The bilabial glottalic /ɓ/ is realized as:
- voiced implosive [ɓ] in initial position
- preglottalized voiced implosive [ˀɓ] in medial position
- preglottalized and unreleased voiceless plosive [ˀp̚] in syllabe coda
^
The alveolar glottalic /ɗ/ is realized as:
- retroflex implosive [ᶑ ] in initial position
- preglottalized retroflex implosive [ˀᶑ ] in medial position
- preglottalized and glottalized lateral approximant [ˀl̰ ] in syllable coda
^ If the glottal stop is interpreted as contrastive, then the preglottalized palatal semivowel /ˀj/ is analyzed as a cluster [ʔj]. Before nasalized and pharyngealized close vowels, it is realized as an epiglottal trilled affricate [ʡʢ].
^ ^a ^b The palatal nasals [ɲ ˀɲ] are found in a subset of onset and coda positions, but are realized as nasalized semivowels [j̃ ˀj̃] in medial position after nasal segments. Anonby (2008) analyzes these sounds as nasal variants of the palatal semivowels /j ˀj/.
^ If the glottal stop is interpreted as contrastive, then the preglottalized labiovelar semivowel /ˀw/ is analyzed as a cluster [ʔw].
^ ^a ^b The labialized velar nasals [ŋʷ ˀŋʷ] are found in a subset of onset and coda positions, but are realized as nasalized semivowels [w̃ ˀw̃] in medial position after nasal segments. Anonby (2008) analyzes these sounds as nasal variants of the labiovelar semivowels /w ˀw/.
^ The palatal semivowel /j/ is nasalized [j̃] when adjacent to nasal vowels.
^ Unlike the palatal semivowel /j/, the labiovelar semivowel /w/ does not have a stable nasalized realization [w̃] when adjacent to nasal vowels. However, the nasal labiovelar [ŋʷ ~ w̃] may behave similarly to [w] when before back vowels, with both merging to [h], suggesting /w/ may be the underlying phoneme.
