The book 'Definiteness in Bulgarian Modelling the Processes of Language Change Trends in Linguistics Studies and Monographs [Tilsm]' provides a comprehensive exploration of the evolution of the Bulgarian language from a synthetic to an analytic language, focusing on the emergence of the grammaticalized category of definiteness. The author examines the process of language change through a detailed comparison of the earliest Modern Bulgarian texts with contemporary dialect and standard Bulgarian data. The study employs a rigorous approach, separating form from content and utilizing a default inheritance model of definiteness to classify and analyze nominal structures encountered in the texts. This allows for a quantitative analysis of the types of nominal structures available in early texts from a native speaker's perspective. The book begins by discussing the need to understand the technological process of developing modern knowledge as the basis for human survival and unity in a warring world. The author argues that the ability to adapt to changing technology is crucial for the survival of humanity, and that this requires the development of a personal paradigm for perceiving the technological process.
