Mongsen Ao is a member of the Ao languages, a branch of the Sino-Tibetan languages, predominantly spoken in central Mokokchung district of Nagaland, northeast India. Its speakers see the language as one of two varieties of a greater "Ao language," along with the prestige variety Chungli Ao.
A chapter in the anthropological monograph of Mills (1926) provides a grammatical sketch of the variety of Mongsen Ao spoken in Longjang village. Coupe (2003) is one of the few acoustic studies published on a Kuki-Chin-Naga language (only three exist). Coupe (2007) is a reference grammar of the language, based on a revision of his PhD dissertation (Coupe 2004).
Phonology
This section describes the sound system of Mongsen Ao as spoken in Mangmetong village and is based on Coupe (2007).
Vowels
Mongsen Ao has 6 vowels:
::data[format=table]
| Front | Central | Back | modal | creaky | Close | Mid | Open |
|---|---|---|---|---|---|---|---|
| :: |
- The high central is rounded.
- The two low vowels differ in terms of phonation type. has modal voice (i.e. normal phonation); has creaky voice (also known as vocal fry, laryngealization). Coupe (2003) argues that this is a separate vowel phoneme and not a tone, a glottal stop, or resulting from prosodic effects.
Consonants
Mongsen Ao has 27 consonants:
::data[format=table]
| Labial | Alveolar | Palatal | Velar | Glottal | Nasal | voiceless | voiced | Plosive | aspirated | tenuis | Affricate | aspirated | tenuis | Fricative | voiceless | voiced | Approximant | voiceless | voiced | Lateral | voiceless | voiced |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

- Dental consonants are laminal denti-alveolar.
- The post-alveolar approximant varies from an apical post-alveolar to subapical retroflex: .
- The glottal stop occurs only at the end of words. However, in this position it contrasts with words ending in vowels: 'spear' vs. 'person'. When a suffix is added to such words, the is deleted: 'to eat' + CAUS → 'to cause to eat'. Thus, the glottal stop has a somewhat marginal phonemic status.
Tone
Ao is a tonal language with 3 contrasting lexical tones:
- high
- mid
- low
All are register tones.
Syllable and phonotactics
The generalized syllable structure of Ao is abbreviated as the following:
:: (C1)V(G)(C2)+T
(C1)
- Any of the 20 consonants may appear as an optional syllable onset (excluding the word-final ).
V
- All 6 vowels may occur as the syllable nucleus.
(G)
- The optional glide elements following the head vowel are essentially non-syllabic offglide realizations of the 4 vowels . For example, → 'species of centipede'.
- The following are the possible tautsyllabic combinations: .
(C2)
- The following consonants may occur in the optional syllable coda: unaspirated stops, nasals, and the rhotic . The glottal stop with its restricted distribution also occurs but only word-finally.
T
All syllables occur with one of the three tones. In a VG sequence, tone only occurs the vowel head.
Syntax
Ao is an SOV language with postpositions. Adjectives, numerals and demonstratives follow the nouns they modify, whilst relative clauses may be either externally or internally headed. Adverbial subordinators are suffixes attached to the verb and the end of the subordinate clause.
