Starting from defining the terms "linguistics, " "applied linguistics" (AL), and "postmodern, " I will show which different interpretations can be attributed to the compound expression "postmodern applied linguistics": "applied linguistics today, " "applied linguistics from a plural(istic), anti-essentialist, antiuniversalistic, etc., point of view," "explicit" versus "implicit postmodern AL, " etc. The discussion refers to AL as a "plural whole," but also to a few of subs-disciplines such as translation studies, intercultural communication, gender linguistics, technical communication, educational linguistics, critical applied linguistics, and language policy. The paper will also discuss the role of a postmodern theory of science as a premise for theories in every scientific discipline. I will plead for a concept of plural theories that could often take more into account the complexity of "reality" than strictly monistic theories. Since AL should be the discipline that mediates between linguists and non-linguists, I will finally refer to the language awareness of lay people, which is still under the almost exclusive influence of "modern" rather than "postmodern" models of reasoning.
