Within Czech linguistics the Czech calque of the English term Functional Sentence Perspective funkční větná perspektiva is nowadays used to refer to the approach stemming from the writings of Jan Firbas and his followers, while the original Mathesius’ Czech term aktuální členění větné tends to be associated with the group of linguists developing the Topic-Focus Articulation, i.e. Petr Sgall, Eva Hajičová, Jarmila Panevová and their disciples, despite the fact that both terms are still sometimes used interchangeably in some Czech contributions to the topic of information structure of language.
