Structural Linguistics is a branch of linguistics that focuses on understanding language as a system of interrelated elements. It emphasizes the relationships between words, sounds, and meanings rather than their historical development. This approach analyzes language structure through its components, such as phonetics, syntax, and semantics, to uncover the rules governing language use. Key figures in Structural Linguistics include Ferdinand de Saussure, whose ideas laid the foundation for this field. Saussure introduced concepts like the linguistic sign, which consists of a signifier (sound) and a signified (meaning). This framework helps linguists study languages systematically and objectively.
