Theoretical linguistics focuses on studying language structure and organization, delving into areas like phonetics, syntax, and semantics. Applied linguistics, on the other hand, is concerned with real-world language use, including language teaching, translation, and language policy. While theoretical linguistics aims to understand the universal principles of language, applied linguistics applies this knowledge to practical issues in language learning and communication.
