This afternon I'm reading Roberston on the 8 case system. Here is his view in a nutshell:
It partly depends on whether one is to apply the term 'case' to the ending or to the relationship expressed by the ending.
Thus, if onoma can be vocative, nominative, or accusative, why can't onomati be dative, locative or instrumental? He has a point!
Much to disucss in tomorrow's Greek class.
