Applied linguistics is an interdisciplinary field which identifies, investigates, and offers solutions to language-related real-life problems. Some of the academic fields related to applied linguistics are education, psychology, communication research, information science, natural language processing, anthropology, and sociology.
Applied linguistics is an interdisciplinary field. Major branches of applied linguistics include bilingualism and multilingualism, conversation analysis, contrastive linguistics, language assessment, literacies, discourse analysis, language pedagogy, second language acquisition, language planning and policy, interlinguistics, stylistics, language teacher education, forensic linguistics, and translation.
The tradition of applied linguistics established itself in part as a response to the narrowing of focus in linguistics with the advent in the late 1950s of generative linguistics, and has always maintained a socially-accountable role, demonstrated by its central interest in language problems.
Although the field of applied linguistics started in Europe and the United States, the field rapidly flourished in the international context.
Applied linguistics first concerned itself with principles and practices on the basis of linguistics. In the early days, applied linguistics was thought as "linguistics-applied" at least from the outside of the field. In the 1960s, however, applied linguistics was expanded to include language assessment, language policy, and second language acquisition. As early as the 1970s, applied linguistics became a problem-driven field rather than theoretical linguistics, including the solution of language-related problems in the real world. By the 1990s, applied linguistics had broadened including critical studies and multilingualism. Research in applied linguistics was shifted to "the theoretical and empirical investigation of real-world problems in which language is a central issue.
