This article presents the results of a research conducted under our supervision by students of the subject “Clearly, honestly, correctly – simplifying banking communication in practice”. The classes were delivered at the University of Warsaw in cooperation with mBank as part of the “Students for the Environment” programme. On this example, we show how to integrate plain-language topics into academic teaching. This article presents also the conclusions formulated based on the research results and further research perspectives on the idea of plain language in the context of a broader phenomenon, i.e. effective communication.
