Functional sentence perspective

In linguistics, functional sentence perspective (FSP) is a theory describing the information structure of the sentence and language communication in general. It has been developed in the tradition of the Prague School of Functional and Structural Linguistics together with its sister theory, Topic-Focus Articulation.

The key concepts of FSP were laid down by Jan Firbas in the mid-1950s on the basis of the linguistic work of Vilém Mathesius, especially his idea of functional syntax in linguistic characterology of language.
