In my thesis I would like to set the fundamental differences and their possible reasons in the focus of attention. I would like to find an answer for the question: what are the main divergences between women and men talk? In the first chapter I intend to investigate the possible causes of the differences and later in the subsequent part of my thesis I will elaborate on the potential malfunctions that may occur in a conversation and which could be caused by theses differences. I will introduce the issue of politeness and slang language use as well and try to investigate these topics in the frame of the chief differences.
