Onomastic morpheme formation in the monastery business writing in the region of Lake White, North Russia, from the late 14th to the 15th century
The examples of the monastery business writing of the region of Lake White (North Russia) in the late 14th century and in the 15th century reflect the processes of formation of posessive topoformants and anthropoformants. The study of these processes is topical since morpheme formation plays an important role in the development of the onomastic subsystem of a language. In the work, a functional-typological approach is used to describe the material: we identify strong and weak morphemes, and discuss the peculiarities of the evolution of possessive suffixes in the sphere of onomastic morpheme formation. The process of formation of onomastic morpheme is considered in the evolutionary cycle. Analysis of the material showed that a change in the way of expressing the onomastic value leads to a change in the significative significance of morphemes, the result of this is the formation of new topoformants and anthropoformants.
