Structural linguistics is a theoretical approach to linguistics that emphasizes the study of language structure. It focuses on analyzing language as a system of interrelated elements, such as sounds, words, and grammar rules. Structural linguistics seeks to uncover the underlying patterns and rules that govern language use, with a primary focus on synchronic (describing a language at a specific point in time) rather than diachronic (tracing language changes over time) analysis. This approach was influential in the early and mid-20th century, paving the way for various modern linguistic theories.
