Inspired by the ideas of the Prague School, the theory of functional sentence perspective (FSP) is concerned with the distribution of information as determined by all meaningful elements, from intonation (for speech) to context. A central feature of FSP is communicative dynamism. Jan Firbas discusses the distribution of the degrees of communicative dynamism over sentence elements, which determines the orientation or perspective of the sentence. He examines also the relation of theme and rheme to, and implementation by, syntactic components. Special attention is paid to the relation between FSP and word order. The second part of the book deals with spoken communication and considers the place of intonation in the interplay of FSP factors, establishing the concept of prosodic prominence. It tackles the relationship between the distribution of degrees of communicative dynamism as determined by the interplay of the non-prosodic FSP factors and the distribution of degrees of prosodic prominence as brought about by intonation.
Jan Firbas discusses the key phenomenon of communicative dynamism, which the sentence elements carry in different degrees, and the distribution of which determines the orientation or perspective of the sentence.
