I'm in Mongolia trying to learn some Mongolian and I've come across their cute word for "litlle", "small": жижиг.
On previous trips through Turkey I recall learning a similar cute word for "little", "small": küçük.
I'm no fanboi of the Altaic Hypothesis but it's pretty accepted here and of course there is lots of contact between Mongolic and Turkic to allow loanwords by some route. Though I would've thought this would be core vocabulary not usually borrowed.
