Although the above quotation is often attributed to Vuk Stefanović Karadžić in Serbia, it is in fact an orthographic principle devised by the German grammarian and philologist Johann Christoph Adelung.[46] Karadžić merely used that principle to push through his language reform.[47] The attribution of the quote to Karadžić is a common misconception in Serbia, Montenegro and the rest of the former Yugoslavia.[citation needed] Due to that fact, the entrance exam to the University of Belgrade Faculty of Philology occasionally contains a question on the authorship of the quote (as a sort of trick question).[citation needed]
