Applied linguistics is a discipline which explores the relations
between theory and practice in language with particular reference to
issues of language use. It embraces contexts in which people use
and learn languages and is a platform for systematically address
problems involving the use of language and communication in realworld
situations. Applied linguistics draws on a range of disciplines,
including linguistics. In consequence, applied linguistics has
applications in several areas of language study, including language
learning and teaching, the psychology of language processing,
discourse analysis, stylistics, corpus analysis, literacy studies and
language planning and policies.
