Linguistics as a course is the scientific study of language, its structure, use, and development. It covers areas such as phonetics (sounds), phonology (sound systems), morphology (word formation), syntax (sentence structure), semantics (meaning), sociolinguistics, psycholinguistics, and language documentation. The course equips students with analytical and research skills, preparing them for careers in language teaching, translation, publishing, speech therapy, computational linguistics, and language preservation.
