وُ. See examples below for words including this vowel: The word for flour is اوُن / un. It is incorrect to spell it as وُن. The word for wheat is بوُغدای / bugdaý. It is incorrect to spell it as باوُغدای In Turkmen, there are two types of syllables, open-ended syllables, which end in a vowel, and close-ended syllables. Open-ended syllables are ones that end in a vowel, i.e. they're in a V or cV form. Close-ended syllables are those that end in a consonant, i.e. they're in a Vc or cVc form. This generally doesn't matter, with the exception of the vowel that represents the same sound as the Latin letter "E". If the syllable is close-ended, the diacritic form of the vowel, ــِـ is used. But if the syllable is open-ended, the ە form is used (similar to how this letter is used as a vowel in Kurdish and Uyghur). Below are examples for the two: Close-ended syllable: The word dessan (meaning: story) is broken down to two close-ended syllables, des-san. Thus, the diacritic form of the vowel "e" is used: دِسسان. It is worth noting that similar to Persian and Arabic, diacritics are often omitted from writing. Open-ended syllable: The word erteki is broken down to three syllables, er-te-ki. Thus, the "e" vowel in the second syllable is written as ە, the word is spelt as ارتەکی. There is one exception to this rule, and that is the suffix "leri", which indicate that a noun is plural and in an objective or possessive case. Despite the suffix consisting of an open-ended syllable, it is written as ـلری. The Latin letter a is generally written as آ / ـا. This is universally true for words of Turkmen origin. However, loanwords, since they're mostly from Persian or Arabic, and already have a proper and familiar spelling, can retain their original spelling. In Persian or Arabic, the same sound can be represented either by the diacritic ــَـ, or by the letter ع, either with diacritic as عَـ or as عا. Consonants While Turkmen Latin Alphabet has 9 vowels and 21 consonants, Turkmen Arabic Alphabet has 32 consonants, as there are sounds that are represented by more than one consonant. The two letters, نگ are treated as one letter, as they are pronounced as a single sound. Notes Turkmen words cannot end in the letter ب / b. Instead, a letter
