completely lost in Moghol, Mangghuer, and Santa. Sporadic shortening of long vowels
is common also in Shira Yughur, Mongghul, and Bonan. As a consequence of the reduc-
tion of short vowels, the long vowels of non-initial syllables in Mongol proper and Oirat
may be assumed to have been shortened, e.g. *(x)ulaan ‘red’ > Khalkha ulang. The
quantitative correlation is, however, retained in the initial syllable.
(18) Initial clusters
As a unique phenomenon in Mongolic, the loss of short vowels in the initial syllable has
created a system of initial consonant clusters in three languages of the Gansu-Qinghai
region: Shira Yughur, Mongghul, and Bonan, cf. e.g. *umba- ‘to swim’ > Shira Yughur
mba-, *erdem ‘virtue’ > Mongghul rdem, *sidü/n ‘tooth’ > Bonan rtung. There are also
other examples of initial vowel loss with phonotactic consequences, e.g. *ire- ‘to come’ >
Mongghul ire- ~ re-, Bonan and Mangghuer re- (with r in the otherwise atypical initial
position).
(19) Consonant palatalization
As an alternative to umlaut, several dialects of Mongol proper, notably Khalkha, have
introduced a series of palatalized consonants, which basically reflect the impact of a sub-
sequently lost *i, e.g. *mori/n ‘horse’ > Khorchin mör vs. Khalkha mory. A similar sys-
tem of palatalization is also present in Dagur, which additionally has a parallel system of
labialized consonants. Another factor that has favoured the distinctive status of the
palatalized consonants is palatal breaking, a feature that unites Dagur and Mongol proper
with Buryat. By contrast, neither palatalization nor umlaut is present in Khamnigan
Mongol, Moghol, and the Gansu-Qinghai complex.
(20) The distinction *k *g vs. *q *gh
This distinction, which arose in Late Pre-Proto-Mongolic due to the neutralization of the
high unrounded vowels *i & *ï > *i, was apparently still valid in Middle Mongol but has
been lost in almost all Modern Mongolic languages. The only modern languages that
retain traces of the distinction are Moghol and Santa, cf. e.g. *kïmusu/n > *qimusu/n
‘fingernail’ > Moghol qimsun, Santa ghimusun. It may be noted that, independently of
the original background, a new opposition between k g and q gh has arisen in several
Mongolic languages, including Oirat, Mongghul, Mangghuer, and Bonan.
(21) Obstruent dissimilation
This feature is present in the southern dialects of Mongol proper (Ulan Tsab, Shilingol,
Juu Uda, and Southern Khalkha), Ordos, and Mongghul, as well as, less regularly, in the
other languages of the Gansu-Qinghai complex. Most typically, it is a question of the
weakening of an initial obstruent before a medial strong obstruent, e.g. *casu/n ‘snow’ >
Mongol proper cas ~ jas, Ordos jasu, Shira Yughur jasen, Bonan (dialectal) jasung,
Santa casun (chasun) ~ jasun (
zhasun). Another manifestation of the same phenomenon
is the strength metathesis of obstruents, which is most systematically observed in
Mongghul, e.g. *bicig ‘writing’ > Mongghul pujig ‘book’.
