Stratificational grammar is a linguistic approach that examines language as a hierarchical system consisting of different, interrelated levels. This approach views language as a constantly evolving system, with each level of structure building on the previous one and influencing the one above it. Synonyms for stratificational grammar include systemic linguistics, hierarchial linguistics, and the Prague School approach. Additionally, it can be compared to other linguistic theories such as generative grammar, transformational grammar, and cognitive linguistics. These theories all share similar goals in understanding the structure and function of language, but differ in their approaches and methodology. Ultimately, the study of language is a multifaceted field with a rich history of different perspectives and approaches.
