I gave him the follwing answer. Please correct me if I am wrong and give us some ideas. I appreciate your suggestions and views if I am totally wrong. Here is my answer:

Applied linguistics is an interdisciplinary science. It studies language and linguistics in relation to practical problems and it studies language teaching and learning. Applied linguistics provides findings and principles that help in language acquisition. These findings and disciplines are brought from researches on linguistics and language. The system of language teaching and learning involves interlocking elements that each one has its role in the process. Teacher, pupil, aids and educational theories are elements that summed up under the system of language teaching and learning. They are modified by the linguists who studies and research on language and linguistics.
