‘structure’ (from *barï- ‘to grab; to construct’), kertü ‘true’ ← Mongolic *gere.tü ‘evident’
(from *gere ‘light’), qarghu ‘watchtower’
← Mongolic *kara.xu (from *kara- ‘to watch’),
and yalawac ‘envoy’ (< *yala.ba.ci ‘invitee’, from Mongolic jala- ‘to invite’). In many
other cases criteria for the direction of borrowing are missing, as in Turko-Mongolic
*kom (qom) ‘a piece of felt placed under the pack on a camel’.
Assuming that the Xianbei and Tabghach were, indeed, linguistically Mongolic (Para-
Mongolic), it is not immediately clear what contemporary ethnic group represented the
Turks. One possible identification is offered by the Ruanruan, who appeared in Mongolia
at the end of the fourth century. The Ruanruan have conventionally been connected with
the Avar, who appeared in Eastern Europe in the middle of the sixth century, but the con-
nection remains both historically and linguistically unconfirmed. The European Avar
have been identified variously as Turks or Mongols. Most recently, it has been suggested
(by Róna-Tas) that they were Bulghar Turks, which would make them descendants of the
Xiongnu. The information on the Avar language consists of names like Bayan (Mongolic
*bayan vs. Turkic *bay ‘rich’) and well-known titles like tarcan (Mongolic *darkan)
and caganus (Mongolic *kaxan vs. Turkic *kagan), none of which is diagnostic enough to
allow firm conclusions.
The first people to use the title *kagan (qaghan) ‘ruler, emperor’ were the Xianbei.
Later on this title was employed by both the Tabghach and the Ruanruan, as well as by
the Khitan and the historical Turks. The Mongols seem to have adopted it from the Turks.
Although the etymology of *kagan remains unclear, it belongs to a distinct type of nouns
ending in n, many of which may have entered Turkic from Mongolic (or Para-Mongolic).
This group comprises Turkic tarqan, as well as qatun ‘queen; lady’, tegin ‘prince’,
qalqan ‘shield’, atan ‘gelded camel’, toghan ‘[kind of] hawk’, lacin ‘gyrfalcon’, and
colban ~ colpan ‘the planet Venus’. In all of these cases, a foreign origin is also suggested
by the semantics (administrative concepts, hunting birds and other domesticated animals,
astronomical terms). There are also many other Turkic words that for phonological, mor-
phological, and/or semantic reasons might be early borrowings from Mongolic. Possible
cases include: Turkic taluy ‘ocean’ (Mongolic *dala.i), bughday ‘wheat’ (Mongolic
*buxuda.i), turumtay ‘hawking bird’ (with the Mongolic suffix *.tA.i), tuturqan ‘rice’.
In the middle of the sixth century the Turkic group bearing the ethnonym Türk
crushed the Ruanruan and gained control of the eastern steppes for the next few hundred
years. The subsequent Türk empires at times also controlled Mongolic and Para-
Mongolic peoples, including the Khitan, who copied political and organizational terms
from Turkic. During this period, the ancestors of the historical Mongols are likely to have
been contained within the entities known by the names Otuz Tatar (Shiwei) and Toquz
Tatar (Southern Shiwei), located east and southeast of Lake Baikal. West and north of
the lake were the Turkic Üc Qurïqan, the linguistic ancestors of the Yakut. In 742 the
Türk were defeated by the likewise Turkic confederation of the Uighur, who, in turn,
were pushed aside by the Ancient Kirghiz in the 840s. Some Uighur tribes took refuge
with the Otuz Tatar, but most of them withdrew to the oases of Eastern Turkestan. The
Uighur then never returned to the steppes, even when they were invited by the Khitan,
who had overcome the Kirghiz in the 920s.
In the twelfth century, part of the Khitan, subseqently known as the Black Khitan
(Qara Qïtay), migrated westward to Central Asia and became Turkicized. In Mongolia,
the immediate linguistic ancestors of the historical Mongols spread Mongolic (Pre-Proto-
Mongolic) speech to territories previously held by Turkic speaking populations. The
Mongols mainly occupied the basins of the rivers Orkhon and Kerulen, but the closely
related Kereit and Naiman tribes expanded further to the west. Both the Kereit and espe-
cially the Naiman may have contained unassimilated Turkic elements, as is suggested by
