Linguistic terms used in works of the Karakhanid era

As scientific sources testify, early and medieval eastern, in particular, Turkic linguistics were significantly ahead in their development of the level of linguistic knowledge in Europe. This is evidenced by the fact that by this period an integral system of linguistic terms had already been formed in the East, a significant part of which was preserved in written monuments of the Karakhanid period. And what is especially noteworthy is that many of them are of Turkic origin. And in this regard, the merit of linguists, historians and literary figures of this period is invaluable. The lion’s share of linguistic terms and requirements for them are inherited by modern Eastern linguistics. However, over time, they nevertheless underwent changes, which affected, first of all, their seman- tics. In particular, they developed polysemy. This article is devoted to the study of the history of the forma- tion and development of Turkic linguistic terms of the Karakhanid period.
