Mungbam language
Mungbam is a Southern Bantoid language of the Lower Fungom region of Cameroon. It is traditionally classified as a Western Beboid language, but the language family is disputed. Good et al. uses a more accurate name, the 'Yemne-Kimbi group,' but proposes the term 'Beboid.'
The language is spoken in four villages, Abar, Munken, Ngun, and Biya. Speakers from each village consider their speech to be distinct, but the dialects are loosely classified as one language because they heavily overlap in grammar and vocabulary and are mutually intelligible. There is no name for the language as a whole. The village name Abar is sometimes used. The name "Mungbam" is a quasi-acronym of the village names plus Missong, which used to be considered a fifth dialect. Speakers from the four villages plus Missong regularly interact with each other in markets, at school, and during celebrations. The language is spoken by approximately 2,000 speakers across the villages, by some young people and all adults. Most Mungbam speakers now use Cameroonian pidgin to communicate with speakers of other languages. This does not seem to be contributing to the decline of Mungbam. Mungbam is classified as a threatened 6b language.
Phonology
Consonants
The consonant inventory is restricted based on the consonant's placement within the morpheme and the type of morpheme. For example, the consonant inventory for affixes is very different from the consonant inventory of word stems.Consonants vary slightly between dialects.
Vowels
quality in Mungbam varies across dialects. The vowel inventory is not restricted by the vowel's placement within the morpheme.Lovegren provides a vowel inventory common across all dialects.

Tone
forms an integral part of Mungbam phonology and morphology. Tones distinguish nouns which are otherwise homophonous. With some exceptions, nouns are assigned tones and retain those tones regardless of syntax and inflection. There are four levels of tone in Mungbam.| Mungbam | Translation |
| bá-bja᷅ŋ | "adjumbu people" |
| bà-bjâŋ | "children" |
Syllable Structure
Attested syllable types vary between stem-initial and non-stem-initial syllables. Word stems in Mungbam can either be monosyllabic or disyllabic. Consonants comprising the only syllable in a monosyllabic stem or the first syllable in a disyllabic stem are referred to as 'stem-initial,' all other consonants are considered 'stem-final.'| Mungbam | Translation | Stem-Initial | Stem-Final |
| m̀bɔ̀ŋ | "cow" | CCVC | |
| m̀be᷅lə | "ribs" | CCV | CV |
Stem-Initial
Attested syllable shapes for stem-initial syllables include, with certain restrictions on where some consonants can appear within those syllables. Very few words begin with vowels in Mungbam; these are primarily restricted to lexical nouns, some pronouns, and some grammatical particles.Stem-Final
Non-stem initial syllables are exclusively CV in shape, almost entirely predictable in terms of tone, and have a very restricted set of possible consonants.Morphology
ation, typically the most common morphological process, is very minimal in Mungbam. Affixation is restricted primarily to prefixes, with semi-rare circumfixes, and few suffixes. Every affix is either derivational or concordant. Derivational affixation typically either nominalizes or adjectivalizes verbs. The most common concordant affixation is that of noun-class prefixes to word stems.Verbs
Verbs most often appear as just the stem, with no affixation at all. Each verb belongs to one of the three verb classes, which are distinct with respect to tone. Most non-tonal verb inflection is done by tense markers, which denote the five temporal tenses, as well as a conditional tense. Tense markers are all words separate from the verb except the perfect marker, which is enclitic. Mungbam morphological inflection mainly comprises tone shift, reduplication, nominalization through affixation, and some rare cases of ablaut.Tone Shift
Tonal inflection includes tone extension and tone sandhi.Tone extension denotes a change in verbal mood. The difference between realis and irrealis verbs corresponds, in part, to a difference between extended and unextended tones. Extension is a morphological process wherein the stem vowel of a noun is lengthened, changing the tone. Extension affects the relative height of each tone.
| Realis | Irrealis | Gloss |
| wù | wu᷅ | 'grind' |
| wû | wú | 'wash.' |
| wû | wú | 'ascend' |
Consecutive verbs in the Missong dialect can experience tone sandhi.
| tse᷅ | 'go!' |
| wɔ᷅ŋ | 'squeeze !' |
| tse᷅ wɔ̋ŋ | 'go and squeeze !' |
Reduplication
Reduplication can either be inflectional or stylistic. Inflectional reduplication in Mungbam establishes verum focus.Stylistic reduplication is not very well attested, Lovegren found only two examples. It might create emphasis.
Nominalization
There are two processes which nominalize verbs: a productive, well-attested process to form infinitives, and a less productive, virtually un-attested process to create the “disability construction.” Infinitives are formed by affixing a noun class prefix or, in rare cases, circumfix. Infinitives in Mungbam function as nouns do, but lack plurals. For more complicated verb phrases, the infinitive can be formed out of the entire phrase by attaching the noun-class prefix to the first verb in the phrase.| gbē | 'fall' |
| ì-gbē | 'falling' |
There is an optional suffix that can be added for some infinitives in Biya. For example, the Biya circumfix as applied to the verb ' tɕī,' :
| tɕī | Imperative |
| ì-tɕī-lə | Infinitive |
The “disability” construction describes humans or animals who are ‘disabled.’ Uniquely, it is the only construction where a noun may not have a noun-class prefix. It is a highly unproductive and uncommon construction.
Here, the verb 'break' has been nominalized as part of the noun phrase 'broken leg' which translates more closely into 'amputee.'
Ablaut
Verbs undergo ablaut to denote changes in aspect. The productivity of ablaut varies across the dialects of Mungbam.| Perfective Stem | Imperfective Stem | Gloss |
| ti | to | 'come' |
| le | lɔ | 'make' |
| ki | kju | 'spit' |
Nouns
With some exceptions, each noun must have a noun-class prefix, but otherwise has little to no affixation.Noun Class System
The most common form of affixation is that of the noun-class prefix. Mungbam, like many Bantoid languages, indicates agreement with a noun-class system. In such a system, each noun has a noun-class prefix, and other morphemes take on that prefix when they agree with that noun. Unlike Indo-European systems, noun-class can be linked to number, gender, or abstraction. Tone is related, but not entirely connected to, noun-class. The tone of the noun-class prefix will often, but not always, follow the tone of the stem.| Noun | Gloss | Noun-Class | Noun |
| ú-kpe̋ | '.house' | 3 | House |
| à-kə̂fə | '/.bone' | 7 or 12 | Bone |
| ì-bé | '.goat' | 9 | Goat |
There are some exceptions to the noun-class system, both within a dialect and among the five dialects. For example, the 7/8 noun-class pairing is found only in Missong, all nouns in those two classes are paired with other classes in the other dialects.
Plurality
Nouns in certain noun classes will have their plural forms in specific other noun classes. For example, nouns in Class 1 often have their plural forms in Class 2. Singular/plural noun-class pairings can be roughly grouped by type of noun.| Singular | Translation | Plural | Translation |
| -ŋ̀kpa᷄nə | 'clay dish' | bə̀-ŋkpa᷄nə | 'clay dishes' |
| -nám | 'husband' | bə́-nám | 'husbands' |
| -m̀bɔ̀ŋ | 'cow' | bə̀-m̀bɔ̀ŋ | 'cows' |
| ù-ndi᷅nə | 'woman' | bə̀-ndi᷅nə | 'women' |
| ù-nɛ̀ | 'person' | bə̀-nɛ̀ | 'people' |
