Originally word-final *n turned into /ŋ/; if *' was originally followed by a vowel that later dropped, it remained unchanged, e.g. ' became , but ' became . After i-breaking, became phonemic. Consonants in words containing back vowels that were followed by ' in Proto-Mongolian became palatalized in Modern Mongolian. In some words, word-final ' was dropped with most case forms, but still appears with the ablative, dative and genitive.Svantesson et al. (2005): 124, 165–166, 205.
