|Traditionally, ESP teaching and learning has revolved around terminology and the ways technical vocabulary of a specific discipline could be gathered and internalized. While terminology is an essential part of ESP, it cannot, on its own, provide sufficient knowledge about any register of the English language. Given the fact that most ESP learners tend to be rather professionals than linguists, they have to be provided by thorough understanding of structures and functions of the particular language variation they are going to use in their field. Therefore, any comprehensive ESP analysis has to encompass all of the three major levels of linguistic investigation, namely grammatical, lexical and lexicogrammatical. All combined, results of these analyses may significantly foster ESP teaching and learning. They make it possible for learning to be more focused on issues relevant for a particular register (e.g. prominent grammatical features, terminology, structure of text, etc.) as well as for learning materials to be prepared in a more suitable way. The aim of the proposed poster is to present a method of analysing each of these levels using specialized electronic corpora.
