Abstract
The question of the source of the pronominal forms , and of the later fully declined forms, presents an unusual situation. It seems clear from earlier work that we should not look for the answer outside Greek, nor probably even outside colloquial Attic Greek of the fifth century. These are strong advantages, but despite them one cannot have much confidence in the solutions so far provided, and there is room for a fresh approach. In addition to this, the usage of the forms does not seem to have been explained satisfactorily, and I shall attempt to clarify it
