This work, which represents an integrated linguistic-argumentative approach, deals with the linguistic, argumentative and rhetorical analysis of English for Science and Technology (EST). The importance of this field for international communication has meant increased interest in the analysis of EST and above all in the analysis of the structure of EST texts.
The work is divided into three parts. The first part analyses important cognitive and argumentative operations, especially with regard to their function in EST. It looks at the types, objectives, forms and structures of arguments and defines and explains central concepts such as common and specific topoi. Part Two deals with how these cognitive and argumentative operations are realised in language, in microstructures and macrostructures, and ends by analysing a complete EST text. The third part takes this article and shows how it could be used in university-level EST teaching.
