This paper proposes a matrix of notional categories for classifying grammatical structures. The use of the matrix is illustrated through question forms. Communicative competence in a language presupposes mastery of the grammatical system of that language. Therefore, in adopting a communicatively appropriate syllabus, containing varieties of linguistic notions and functions, one must ensure that grammar is not sacrificed. In acknowledging this, three categories of meanings of utterances are presented--semantico-grammatical, modal, and communicative function. Each of these categories is isolated and identified for the question form. Also discussed is the development of a check list matrix to aid the syllabus constructor in ensuring that a specific grammatical structure will be taught within a notional framework. This check list allows the adaptation of a synthetic syllabus into a more analytic and notional syllabus. (Author/JK)
