Mangbetu language

(Redirected from ISO 639:lmi)

Mangbetu, or Nemangbetu, is one of the most populous of the Central Sudanic languages. It is spoken by the Mangbetu people of northeastern Congo. It, or its speakers, are also known as Amangbetu, Kingbetu, Mambetto. The most populous dialect, and the one most widely understood, is called Medje. Others are Aberu (Nabulu), Makere, Malele, Popoi (Mapopoi). The most divergent is Lombi; Ethnologue treats it as a distinct language. About half of the population speaks Bangala, a trade language similar to Lingala, and in southern areas some speak Swahili.

The vowels /a/, /ɛ/, /ɔ/, and /o/ can also be differentiated through quantity and be pronounced both long and short. There are also multiple rising diphthongs: /ai/, /au/, /ei/, /ɛɪ/, /oi/, /ɔɪ/, /ou/ and /ɔʊ/.[5]

The description of the vowels of Mangbetu as constituting a system of tongue root harmony is conventional and should not be taken as a precise description of the phonetic character of the vowel system. The two sets of vowels are differentiated by the vertical movement of the larynx, among other articulatory factors.[5] The system has also been described more loosely as having an opposition of tense (tendues) and lax (relâchées) vowels.[6] Vowels in affixes assimilate to the "tongue root" quality of the vowels found in the root or stem of the word in question, with /a/, /ε/, /ɪ/, /ɔ/, /ʊ/ resulting in -ATR and /e/, /i/, /o/, /u/ in +ATR vowels. However, /a/ can also be considered as an opaque element, because it can stop the vowel harmony from spreading such as in nɛ́ɛ́kábú ‘sadness’.[5]

Retroflex consonants are slightly trilled as [ʈʳ], [ɖʳ], [ᶯɖʳ].[5]

Tone

edit

There is a distinction between high and low tones in Mangbetu, with multiple minimal pairs distinguished only by tone: náŋwɛ́ 'kola nut'-naŋwɛ́ 'moon'; nɛ́ɓà 'village'-nɛ́ɓá 'kind of tree'.[5] Rising and falling tones might also be phonemic.[5]

Phonotactics

edit

Mangbetu syllables are always open, with the shortest syllables consisting of just a vowel, and the longest consisting of a consonant, followed by a glide, followed by a vowel, or CGV.

Other Features

edit

One unusual feature of Mangbetu is that it has both a voiced and a voiceless bilabial trill as well as a labial flap.[7][8]

[nóʙ̥ù] "to bring out"
[nóʙù] "to fan"
[nómʙù] "to enclose"
[nóⱱò] "to defecate"
[nóʙò] "to get fat"

The labial trills are not particularly associated with back vowels or prenasalization, pace their development in some American languages.[9]

[éʙ̥ì] "leaping like a leopard"
[nɛʙàʙá] "kind of plan"

Morphology

edit

Mangbetu words are constructed through the use of various affixes attached to a lexical root. These roots typically consist of a consonant-vowel combination preceded by a ‘characteristic vowel.’. For example, the word ná-mutali, ‘fish,’ can be broken down into the segments ná-mu-t-a-li, containing the root -li, the characteristic vowel -a-, prefixes -t- and -mu-, and the singular marker ná-.[6]

Tonal variation plays a significant role in the language’s morphology, particularly in differentiating singular and plural nouns. For example, in two-syllable words, these changes may involve tone inversion, as in nɛ́gɔ̀ (‘bed’) and ɛ́gɔ̀ (‘beds’), or modification of the second tone, as in nári (‘bird’) and ári (‘birds’). Although, it is also possible for the plural form of a word to have the same tonal pattern as the singular.[6]

Verbal Inflection

edit

Tense and Aspect

edit

Larochette notes that Mangbetu differentiates between three levels of temporal proximity in its Past and Future tenses: recent, moderately recent, and remote.[6] He also writes of a Present-Intensive tense, which marks the intensity of a present action.[6]
