For most scholars, the problem has been in how to connect the Slovene and the German names. The origin from the Slavic ''ljub''- "to love, like" was in 2007 supported as the most probable by the linguist Tijmen Pronk, a specialist in comparative Indo-European linguistics and Slovene dialectology, from the University of Leiden. He supported the thesis that the name of the river derived from the name of the settlement. The linguist Silvo Torkar, who specialises in Slovene personal and place names, argued for the thesis that the name ''Ljubljana'' derives from ''Ljubija'', the original name of the Ljubljanica River flowing through it, itself derived from the Old Slavic male name ''Ljubovid'', "the one of a lovely appearance". The name ''Laibach'', he claimed, was actually a hybrid of German and Slovene and derived from the same personal name.
