ABSTRACT
It is obvious that a teacher must be able to communicate, if his teaching is to be understand by his audience. This creates dificulties if he wishes to teach something new, for which terms do not yet exist. He has the choice of coining new terms or of using old terms in a new sense. Both categories must be clearly defined, or his listeners may not understood the first and may understand the second in their old sense. An investigation into the terminology used by the Buddha shows how he coped with this problem.
