This article explores the intricate relationship between the structural stability of language and its communicative flexibility by conducting a comprehensive functional-semantic analysis of static units during the process of syntactic derivation. Static units, defined as the abstract, invariant templates within a language system, serve as the primary source for generating meaningful utterances. The central focus of this research is to determine how the inherent semantic potential of these abstract units is activated and modified as they undergo derivation to become functional components of speech. By examining the transition from "langue" to "parole," the study identifies the specific functional roles that static units assume when they are integrated into various syntactic paradigms. The research argues that syntactic derivation is not merely a formal rearrangement of linguistic elements but a semantic evolution where the core meaning of a static unit is enriched by context and communicative intent. Through a detailed analysis of various sentence models, the article demonstrates how the functional value of a unit is constrained by its underlying semantic structure.
