Show moreDuring their migration from the Eastern European steppes to the Tarim Basin, the ancestors of the Tocharians must have come into contact with speakers of different languages, which may have influenced the early Tocharian language. Early Uralic has been identified as possibly having been the source of such influence, especially in the domain of phonology and nominal morphology. In a 2019 article, Michaël Peyrot focused specifically on pre-Proto-Samoyed influence on Tocharian, proposing among other things a comparison of the vowel systems. I will discuss this comparison and give an alternative interpretation. Three difficulties remained with Peyrot’s comparison regarding details of 1) the relative chronology of Tocharian sound changes, 2) the mechanism of change, and 3) the relative chronology of sound changes in Samoyed. After addressing these problems in more detail, I conclude that a different vowel comparison is possible, so that the hypothesis that pre-Proto-Tocharians were in contact with pre-Proto-Samoyed substrate is still plausible.
