fraasisüsteem

Fraasisüsteem is a concept in linguistics that refers to the organized set of phrases and fixed expressions within a language, including their syntactic behavior and semantic roles. The term combines fraas (phrase) and süsteem (system) in Estonian scholarly usage, and it is used to analyze how phrases function in sentences, how they are formed, and how they interact with other grammatical units. It encompasses both fixed expressions and more flexible phrasal units.

The fraasisüsteem includes idioms, collocations, multiword expressions, and phrasal units such as noun phrases, verb phrases, and prepositional phrases when they function as stable chunks. It distinguishes between fully fixed phrases, semi-fixed phrases, and more productive, combinatorial phrases. The system is studied in terms of their syntactic positions, their semantic contribution, and their pragmatic use within different contexts.

Researchers analyze fraasisüsteem with corpus data and various grammatical frameworks to map how phrases operate across dialects, registers, and historical stages. The concept connects lexicology, syntax, semantics, and pragmatics and has practical implications for dictionary compilation, language teaching, and natural language processing.

In practice, understanding the fraasisüsteem helps explain why certain word sequences behave as single units and how they influence meaning, fluency, and precision in language use. It remains a focus of ongoing linguistic research, bridging theory and applied language studies.
