Continuing on previous research, in this part of a paper series, a total of thirty-nine newly found suggested borrowings from the Turkic, Tungusic and Mongolic (and Russian) languages into the Yukaghir languages and dialects of far northeastern Siberia are presented as loanword etymologies, which is followed by the discussion of a few tentative cases. The chronology of the borrowings is considered, and solid phonological and semantic considerations are given for each suggestion, and other possible cognates or borrowings in the surrounding languages are also discussed. Further, some transcriptional corrections to the documentation of older Yukaghir lexicon is suggested. The results again highlight the extensive historical social contacts between the Yukaghir populations and surrounding tribes.
