Applied Linguistics is the interdisciplinary field that uses linguistic theories to solve real-world problems, particularly in language education. This tag is dedicated to exploring the fascinating intersection of linguistics, psychology, and pedagogy, providing a platform for discussing how academic theories can be translated into practical strategies for language teachers and learners. Our content covers a wide range of topics, from the analysis of language errors and the development of language tests to the design of language curricula, examining how research in areas like sociolinguistics and psycholinguistics can inform language teaching methodologies and helping you gain a deeper understanding of the “why” behind the “how” of language learning and teaching.
