Comments: Lee 1958, 118, Poppe 1950, 580, Дыбо 10. Doerfer (TMN 2, 550-553), and similarly Щербак 1997, 157, regard the Mong. forms as borrowed < Turkic, where he derives all the above forms from *tul- 'abgesperrt sein' (a poorly attested reflexive form of the equally poorly attested *tu- 'absperren'): hardly acceptable. Since only the velar derivatives (in -kuk, -uk) are early attested in Turkic, it seems more plausible to regard forms like tulum / tulup as borrowed from Mongolian.
