Context: On the other hand, the opinion of Jagić from 1864 is argued not to have firm grounds. When Jagić says "Croatian", he refers to a few cases referring to the Dubrovnik vernacular as ilirski (Illyrian). This was a common name for all Slavic vernaculars in Dalmatian cities among the Roman inhabitants. In the meantime, other written monuments are found that mention srpski, lingua serviana (= Serbian), and some that mention Croatian. By far the most competent Serbian scientist on the Dubrovnik language issue, Milan Rešetar, who was born in Dubrovnik himself, wrote behalf of language characteristics: "The one who thinks that Croatian and Serbian are two separate languages must confess that Dubrovnik always (linguistically) used to be Serbian."
