Abstract
The study of communication extends beyond spoken and written language into broader semiotic systems that encompass nonverbal forms of interaction. This article provides a theoretical overview of surdo language, paralinguistic means, extralinguistic features, and the nonverbal semiotic system. The discussion highlights their distinct roles in human communication and examines the interrelationship between linguistic and nonlinguistic channels. By outlining the theoretical framework of these phenomena, the article emphasizes their importance in linguistics, semiotics, and intercultural communication studies.References
