By "traditional grammar" I mean the kind of grammatical system set out in and presupposed by standard modern grammars of Greek and Latin like Kühner-Gerth or Kühner-Stegmann. Since grammars of this kind traditionally have been followed quite closely by grammarians of other languages one may speak traditional grammar quite generally. Grammars of this type consist of three parts: a phonology, dealing among other things with the sounds of the language, a morphology, dealing with word-formation and -inflection, and finally a syntax in which we are told which combinations of words constitute a phrase or a sentence. Moreover, such grammars are characterized by a certain set of concepts, especially the so-called grammatical categories, that is, notions of various parts of speech like that of a noun or a verb, and notions of various features of these parts of speech which traditionally are called "accidents" or 'secondary categories". Examples of such accidents are gender, number, case, mood, tense.
