"Compositional grammar" refers to a type of linguistic framework that breaks language down into its constituent parts and analyzes how those parts combine to create meaning. Other synonyms for this term might include "structural grammar," which emphasizes the underlying structures or patterns that give language its coherence, or "generative grammar," which focuses on the rules and processes that govern how language is generated by the human brain. Other related concepts might include "syntactic analysis," which examines the relationships between words and phrases in sentences, and "semantic analysis," which explores the meanings conveyed by those relationships. Ultimately, all of these terms point to the idea that understanding language requires careful analysis of its basic building blocks.
