Kókborok sounds and phonetics

Debbarma Kókborok is a typical Sino-Tibetan language and consists of the following sounds:

Vowels
Original writers decided to use the letter w as a symbol for a vowel which does not exist in the English language.

Consonants
N' is the pronunciation of the nasal sound; e.g., in' (yes).

Ng is a digraph and is generally used in the last syllable of a word; e.g., aming (cat), holong (stone).

Ua is often used initially; e.g., uak (pig), uah (bamboo), uatwi (rain).

Uo is often used finally; e.g., thuo (sleeping), buo (beat).

Diphthong
A diphthong is a group of 2 vowels. The wi diphthong is spoken as ui after sounds of the letters m and p. Two examples are: chumui (cloud) and thampui (mosquito). The ui diphthong is a variation of the wi diphthong. Other less frequently occurring diphthongs such as oi are called closing diphthongs. A closing diphthong refers to a syllable that does not end in a consonant.

Syllables
A majority of words are formed by combining the root with an affix. Some examples are;
 * kuchuk is formed from the root chuk (to be high), with the prefix, ku.
 * phaidi (come) is formed from the root phai (to come), with the suffix di.

There are no Kókborok words beginning with ng. At the end of a syllable, any vowel except w can be found, along with a limited amount of consonants: p, k, m, n, ng, r and l. Y is found only in closing diphthongs like ai and wi.

Clusters
"Clusters" are a group of consonants at the beginning of a syllable, like phl, ph + l, in phlat phlat (very fast), or sl in kungsluk kungsluk (foolish man). Clusters are quite impossible at the end of a syllable. There are some "false clusters" such as phran (to dry) which is actually phw-ran. These are very common in echo words : phlat phlat, phre phre, prai prai, prom prom, etc.
