Especially in everyday language, the dis Etinction between the terms 'ethics' and 'morality' is not always clear. Even in some philosophical texts both are used synosymously, while others seem to draw a clear distinction between them. Historically, the term 'ethics' comes from Greek ethos which means the customs, habits and mores of people. 'Morality' is derived from Latin mos, moris which denotes bosically the same; it was introduced by Cicero as an equivalent to the Greek ethos.
