In this paper, I look at three polemical issues in Applied Linguistics. I argue, first of all, that the desire for a stable definition of applied linguistics has by no means prevented research in the discipline. Secondly, I contend that the notion or "tradition" of "linguistics applied" (corpus linguistics or lexicography) is broader and more serious than "applicationism" (the use of linguistic formalisms, artificial practices, and terminology) in teaching material that are problematic and motivated by commercial interests. Thirdly, I argue that Educational Linguistics and Applied Linguistics have overlapping research objectives. In the course of the paper, I present some reservations about Educational Linguistics.
