Monophthongal vowels are, diphthongs are. and may be and word-initially. is written and is written. Only and the diphthongs occur word-initially, apart from the quotative particle, which is variably /a~e~o~ö/. occur syllable-initially within a word. All vowels occur syllable-medially, syllable-finally and at the ends of words. Many vowel sequences occur, including some with identical vowels.
Voiced obstruents may be prenasalized after vowels, depending on the preceding consonant, and are voiceless word-initially. Liquids other than tend toward final devoicing. For example, final is and final tends to. Voiceless consonants other than and are optionally voiced between vowels. is sublaminal retroflex. It has been described as a lateral flap,. All consonants occur syllable initially, though only occurs word-initially in a single mimetic word. All consonants but occur syllable- and word-finally. Clusters occur in many VC.CV words, as well as initially in a handful of mostly monosyllabic CCV words. Attested initial clusters are. Intervocalically, the lenis obstruents are oral when a nasal or another lenis obstruent occurs in the preceding syllable, and are prenasalized otherwise, with some variability after. They are often oral in a medial cluster after another consonant. Otherwise the allophones in the table above are largely in free variation.
Grammar
Kobon is a subject–object–verb language. Singular, dual, and plural are distinguished in personal pronouns and kinship terminology. Like the other Kalam languages, Kobon is famous for having a very small number of verbs—perhaps less than 120 for the entire language. These verbs are combined with nouns into phrases with specific meanings, much as one says "have dinner" rather than "dine" in English. This makes for an interesting window into semantics. One might expect that with a very limited set of verbs, their meanings would be quite general as have, do, be and go are in English. To a certain extent this is really the case, as there is for example only one verb of perception. That is, the same verb is used for see, hear, taste, smell, feel, think, and understand. Another verb is used for making sound, whether it's speaking, singing, praying, crying, twigs breaking, rocks clattering, or water gurgling. However, some Kobon verbs are quite specific. There is one exception for sound, for example: there's a specific verb for calling a pig. There are also three verbs of pouring, depending on whether the thing being poured is solid, liquid, or food; and there is even a verb that means to quarter a cassowary.
Writing system
Kobon has been written in the Latin alphabet for over 30 years. The special letters ƚ and ɫ are used for the subapical retroflex lateralflap and palatal lateral, respectively. 5-15% of Kobon speakers are literate.
