Abstract: The object of research in this article is a concept in the aspect of cognitive linguistics. In the middle of the last century, a cognitive field appeared in science, which unites many scientific disciplines. Cognitive science explores the human mind, its thinking abilities, consciousness, memory, etc. Language is used by humans not just to exchange information, it structures knowledge about the world. The concept is a basic concept of cognitive linguistics, combining language, consciousness and culture. The purpose of this article is to study the content of the concept and build its cognitive model using the example of the concept of "will", which will reveal the ways of structuring knowledge about the world, as well as the ways of their evolution.
The methodology of conceptual analysis is based on the study of the meanings of words and expressions that actualize the concept in the language. Etymological analysis makes it possible to identify the central image of the concept, around which conceptual meanings are layered.
The study of the concept of "will" in cognitive linguistics makes a significant contribution to understanding the interaction of language, thinking and culture, as well as to the development of methods for analyzing linguistic and cultural concepts. This study for the first time combines the analysis of the historical development of the concept with its cognitive structures such as metaphors, frames and prototypes, which allows us to create a comprehensive understanding of the concept of "will" in the Russian language. A comprehensive study of the ways and means of lexical expression of the concept of "will" reveals the conceptual content. All of the above determines the relevance of this article. The research results can be used in cognitive linguistics, psychology, and philosophy of language.

Abstract: Changes in the field of quantum theory taking place in modern science have also affected linguistics. Quantum mechanics is one of the major achievements of past difficulties. The object of study of quantum theory is a minimal, weekly particle - a quantum. The functional liquidity of quanta and linguistic units has been revealed, which makes it possible to transfer research from quantum mechanics to the field of cognitive linguistics. The quantum-cognitive approach expands the view of the concept of nature, highlights its quantum properties and allows us to consider its dynamics as a quantum wave process. In the article, the subject of research is the concept, its dynamics as a change in the states of the concept and its interaction in various combinations. The work pays attention to such phenomena as quantum entanglement, quantum nonlocality, measurement, and contextuality.
Modeling in the quantum-cognitive aspect involves considering changes in the state of a concept under the influence of context. The state of the concept through the prism of quantum mechanics is considered as a wave function that changes under the influence of context. To apply general methodological approaches to describing both phenomena, we will focus on such phenomena as “quantum uncertainty” and “quantum entanglement.”
The article explores the concept through the prism of quantum theory. The material for the study was scientific publications and articles selected by a continuous sampling method on the topics “Quantum Physics”, “Quantum Mechanics”, “Quantum Physics”, “Cognitive Linguistics”.
The object of study of the article is the concept as a quantum immaterial cognitive formation that exists in the human mind. The study of the concept is based on a synthesis of the principles of two scientific directions: quantum mechanics and cognitive linguistics.
