Specialized language from the spheres of pedagogy and psychology constitutes a fundamental aspect within the teacher – student communication. The submitted paper handles lexical and morphological features of compound nouns containing the nouns amnesia, memory and recall. The primary research interest focuses on collocations and concordances in which they appear on a regular basis; we also deal with the grammatical relations and elements of meaning that have an impact on the discourse characteristics. The studied lexical units are elaborated within English Web 2015 utilizing Sketch Engine. In the research, both quantitative (statistical methods) and qualitative (observation, comparison, generalization, data-driven research data modelling) methods were employed. To begin with, we provide the frequency list of the studied words within the text corpus, and we categorize them from the morphological perspective as the two aspects influence their lexical behaviour and employment for teaching purposes. The research outcomes indicate that the analysed lexical units exist in a broad discourse scope; moreover, they appreciably grant profitable acts of communication in the pedagogical settings. Eventually, we outline feasible pedagogical inferences of the inquiry outcomes in the teaching of English and we suggest a set of corpus-driven exercises on the professionally-oriented language from the fields of pedagogy and psychology. To sum up, the outcomes confirm that the lexical and semantic characteristics of specialized language underline social aspects of communication between experts (and public too). Further, we intend to elaborate words belonging to other spheres of professional communication (medicine, sociology, etc.) in the framework of the corpus examination.
