English in academic and professional settings has received great attention over the last 50 years, as its use has become a key asset for anyone interested in improving his/her chances of communicating internationally. However, it still offers rich opportunities for teachers and researchers working on English in specific settings. The aim of English for Professional and Academic Purposes is to offer an overview of several topics within the field of discourse analysis applied to English in academic and professional domains. The book compiles contributions from different origins, ranging from Japan to the USA and several European countries, and covers English as a native, second, foreign and international language. It also deals with various specialities, including academic writing, business discourse or English for medicine, nursing, maritime industry and science and engineering. This volume is divided into three sections: Discourse Analysis of English for Academic Purposes, Professional English and EPAP Pedagogy, since it was conceived as a contribution to the research on how English is analysed as both the discourse of and for effective communication in academic and professional settings, and how it can be applied to teaching. This manuscript offers some fresh insights for those involved or interested in this field of expertise, in an attempt to shed some light on its latest innovations.
