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. Tone There are two tones in Kókborok: high tone and low tone. To mark the high tone, the letter h is written after the vowel with the high tone. These examples have low tone preceding high tone to show that tone changes the meaning: lai easy laih crossed bor senseless bohr to plant cha correct chah to eat nukhung family nukhuhng roof Grammar There is a clear-cut difference between nouns and verbs. All true verbs are made with a verbal root followed by a number of suffixes, which are placed not randomly but according to definite rules.
