the orthography of the mongolian latin is based on the orthography of the classical mongolian script. it preserves short final vowels. it does not drop unstressed vowels in the closing syllables when the word is conjugated. the suffixes and inflections without long or i-coupled vowels are made open syllables ending with a vowel, which is harmonized with the stressed vowel. the rule for the vowel harmony for unstressed vowels is similar to that of the mongolian cyrillic. it does not use consonant combinations to denote new consonant sounds. for both of the version, letter "b" is used both in the beginning and in the middle of the word. because it phonetically assimilates into sound , no ambiguity is caused.
