Abstract. This article explores the linguo-cognitive and cultural features of scientific discourse, focusing on how language, thought, and cultural frameworks interact in the construction and communication of scientific knowledge. By applying cognitive linguistic theories, the study analyzes the role of key mental constructs such as concepts, schemas, and mental models in shaping the structure and meaning of scientific texts. It also investigates how scientific language reflects abstraction, categorization, and metaphorical reasoning, providing insight into the cognitive patterns that underlie academic communication. Additionally, the article considers cross-cultural variations in scientific discourse, highlighting the challenges faced by multilingual scholars and the importance of intercultural competence in global science. The study concludes that scientific discourse is not merely a technical tool but a cognitively and culturally embedded mode of thinking and expression.
