köken: Borrowed from Serbo-Croatian Sarajevo, by re-analyzing -evo as the Slavic derivational suffix -ov, rather than etymologically as Turkish ova (“plains”); alternatively, borrowed from Ottoman Turkish سرای بوسنه (Saray-Bosna) with the second half lost as it simply means Bosnia. As the first part is from Classical Persian سرای (sarāy, “house, palace”), the a could be rendered long by Neo-Latinists.
