. /ɡ/ and /ɢ/ are both indicated by the letter г ⟨g⟩, but the phonetic value of that letter is mostly predictable. In words with "front" (+ATR) vowels (see Mongolian phonology for details), it always means /ɡ/, because only /ɡ/ occurs in such words. In words with "back" (−ATR) vowels, it always means /ɢ/, except syllable-finally, where it means /ɡ/; to acquire the value of /ɢ/, it is written as followed by a single mute syllable-final vowel letter. Similarly, a mute vowel is added to final н ⟨n⟩ to make it denote /n/ and not /ŋ/. A /j/ preceding a vowel is rendered by a combination of a "soft" and "hard" vowel letter, e.g. яа ⟨jaa⟩ stands for /ja/, not */jaː/.
