Tsar
Meaning in Slavic languages
From this ambiguity, the development has moved in different directions in the different Slavic languages. Thus, the Bulgarian language and Russian language no longer use "tsar" as an equivalent of the term imperator as it exists in the West European (Latin) tradition. Currently, the term "tsar" refers to native sovereigns, ancient and Biblical rulers, as well as monarchs in fairy tales and the like. The title "king" (Russian korol' , Bulgarian kral-, the origin of which is Charlemagne (Karl)) is sometimes perceived as alien and is by some Russian speakers reserved for (West) European royalty (and, by extension, for those modern monarchs outside of Europe whose titles are translated as "king" in English, roi in French etc.). Foreign monarchs of imperial status, both inside and outside of Europe, ancient as well as modern, are generally called imperator (император) rather than tsar.
