===Relationship with Turkic===
{{further|Turco-Mongols}}
Pre-Proto-Mongolic has borrowed various words from [[Turkic languages]].

In the case of Early Pre-Proto-Mongolic, certain loanwords in the Mongolic languages point to early contact with [[Oghur languages|Oghur]] (Pre-Proto-Bulgaric) Turkic, also known as r-Turkic. These loanwords precede [[Common Turkic]] (z-Turkic) loanwords and include:
*Mongolic ''ikere'' (twins) from Pre-Proto-Bulgaric ''ikir'' (versus Common Turkic ''ekiz'')
*Mongolic ''hüker'' (ox) from Pre-Proto-Bulgaric ''hekür'' (Common Turkic ''öküz'')
*Mongolic ''jer'' (weapon) from Pre-Proto-Bulgaric ''jer'' (Common Turkic ''yäz'')
*Mongolic ''biragu'' (calf) versus Common Turkic ''buzagu''
*Mongolic ''siri-'' (to smelt ore) versus Common Turkic ''siz-'' (to melt)

The above words are thought to have been borrowed from Oghur Turkic during the time of the [[Xiongnu]].

Later [[Turkic peoples]] in Mongolia all spoke forms of Common Turkic (z-Turkic) as opposed to [[Oghur languages|Oghur]] (Bulgharic) Turkic, which withdrew to the west in the 4th century. The [[Chuvash language]], spoken by 1 million people in European Russia, is the only living representative of Oghur Turkic which split from Proto Turkic around the 1st century AD.

Words in Mongolic like ''{{lang|mn|dayir}}'' (brown, Common Turkic ''yagiz'') and ''nidurga'' (fist, Common Turkic ''yudruk'') with initial *d and *n versus Common Turkic *y are sufficiently archaic to indicate loans from an earlier stage of Oghur (Pre-Proto-Bulgaric). This is because Chuvash and Common Turkic do not differ in these features despite differing fundamentally in rhotacism-lambdacism (Janhunen 2006). Oghur tribes lived in the Mongolian borderlands before the 5th century, and provided Oghur loanwords to Early Pre-Proto-Mongolic before Common Turkic loanwords.{{sfn|Golden|2011|p=31}}
