[1] Pranjković is a Bosnian Croat, born in Kotor Varoš in Bosnia and Herzegovina.
After the classical secondary school in Visoko, he received a BA degree in Croatian from the Faculty of Humanities and Social Sciences at the University of Zagreb.
This last topic was the subject of several studies of Pranjković, as well as the book Hrvatski jezik i franjevci Bosne Srebrene (Croatian and the Bosnian Franciscans), where he described the linguistic area which was crucial for the development and standardization of Croatian, but which was greatly neglected until his work.
Aside from linguistic theory and history, Pranjković engaged in many disputes and comments in the press, especially with his great rival, Stjepan Babić.
