In this position, he transformed the linguistic section of the academy into the central regulatory authority for codification of Slovene.
Toporišič was born in the village of Mostec[2] near Brežice in Slovenia, in what was then the Kingdom of Serbs, Croats and Slovenes.
After returning to Slovenia in the early 1960s, he received his doctorate in 1963 at the Faculty of Arts in Ljubljana with the dissertation Nazorska in oblikovna struktura Finžgarjeve proze (The Conceptual and Formal Structure of Finžgar's Prose).
In addition to Slovene, he was fluent in German, Russian, Serbo-Croatian, and English; he also read Polish and other Slavic languages.
Due to this, the general public often attributed to him the authorship of every neologism that entered Slovene through the media or the educational system, although this was not always the case.
