century. It is a large stone tablet found in the small Church of St. Lucy, Jurandvor on the Croatian island of Krk, containing text written mostly in Čakavian dialect in angular Croatian Glagolitic script. The independence of Dubrovnik facilitated the continuity of the tradition. More recent foreign influences follow the same general pattern in Slavic languages as elsewhere and are governed by the political relationships of the Slavs. In the 17th century, bourgeois Russian (delovoi jazyk) absorbed German words through direct contacts between Russians and communities of German settlers in Russia. In the era of Peter the Great, close contacts with France invited countless loan words and calques from French, many of which not only survived but also replaced older Slavonic loans. In the 19th century, Russian influenced most literary Slavic languages by one means or another. Differentiation The Proto-Slavic language existed until around AD 500. By the 7th century, it had broken apart into large dialectal zones. There are no reliable hypotheses about the nature of the subsequent breakups of West and South Slavic. East Slavic is generally thought to converge to one Old East Slavic language, which existed until at least the 12th century. Linguistic differentiation was accelerated by the dispersion of the Slavic peoples over a large territory, which in Central Europe exceeded the current extent of Slavic-speaking majorities. Written documents of the 9th, 10th, and 11th centuries already display some local linguistic features. For example, the Freising manuscripts show a language that contains some phonetic and lexical elements peculiar to Slovene dialects (e.g. rhotacism, the word krilatec). The Freising manuscripts are the first Latin-script continuous text in a Slavic language. The migration of Slavic speakers into the Balkans in the declining centuries of the Byzantine Empire expanded the area of Slavic speech, but the pre-existing writing (notably Greek) survived in this area. The arrival of the Hungarians in Pannonia in the 9th century interposed non-Slavic speakers between South and West Slavs. Frankish conquests completed the geographical separation between these two groups, also severing the connection between Slavs in Moravia and Lower Austria (Moravians) and those in present-day Styria, Carinthia, East Tyrol in Austria, and in the provinces of modern Slovenia, where the ancestors of the Slovenes settled during first colonisation. In September 2015, Alexei Kassian and Anna Dybo published, as a part of interdisciplinary study of Slavic ethnogenesis, a lexicostatistical classification of Slavic languages. It was
