‘(Ne) Khukhry-Mukhry’: One Russian Idiom of Mongolian Origin Revisited

. The paper examines the etymology of the idiom ‘ (ne) khukhry-mukhry ’ which in its form fully corresponds to the so-called pair words widely used in Turkic, Mongolic and some Finno-Ugric languages. Several generations of researchers have sought for the actual etymology of this idiom. The revealed complex of features associ-ated with the idiom suggests that this expression goes back to the Mongolic languages and may be one of the earliest Mongolian borrowings in the Russian language.
