Syntactic representations are formal descriptions of the grammatical structure of linguistic expressions, specifying how words and phrases are organized and related within a sentence. They encode structural information through frameworks such as phrase-structure trees, dependency structures, and other grammatical formalisms, each of which represents syntactic relationships according to distinct theoretical assumptions ^[1][2]. These representations may identify constituents, hierarchical organization, grammatical functions, and dependencies between linguistic elements. In computational linguistics, syntactic representations also serve as structured data for parsing, grammatical analysis, and natural language processing. Their formal properties depend on the representational framework adopted, including its categories, relational conventions, and principles for describing sentence structure ^[1][2][3].
