Common roots and ancestry Slavic languages descend from
Proto-Slavic, their immediate
parent language, ultimately deriving from
Proto-Indo-European, the ancestor language of all
Indo-European languages, via a
Proto-Balto-Slavic stage. During the Proto-Balto-Slavic period a number of exclusive
isoglosses in phonology, morphology, lexis, and syntax developed, which makes Slavic and
Baltic the closest related of all the Indo-European branches. The secession of the Balto-Slavic dialect ancestral to Proto-Slavic is estimated on archaeological and glottochronological criteria to have occurred sometime in the period 1500–1000 BCE. A minority of Baltists maintain the view that the Slavic group of languages differs so radically from the neighboring Baltic group (
Lithuanian,
Latvian, and the now-extinct
Old Prussian), that they could not have shared a parent language after the breakup of the
Proto-Indo-European continuum about five millennia ago. Substantial advances in Balto-Slavic
accentology that occurred in the last three decades, however, make this view very hard to maintain nowadays, especially when one considers that there was most likely no "
Proto-Baltic" language and that
West Baltic and
East Baltic differ from each other as much as each of them does from Proto-Slavic. , 11th century,
Krk,
Croatia Differentiation The
Proto-Slavic language originated in the area of modern
Ukraine and
Belarus mostly overlapping with the northern part of
Indoeuropean Urheimat, which is within the boundaries of modern
Ukraine and
Southern Federal District of Russia. 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 of
Kievan Rus, 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 colonization. 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 built using qualitative 110-word Swadesh lists that were compiled according to the standards of the Global Lexicostatistical Database project and processed using modern phylogenetic algorithms. The resulting dated tree complies with the traditional expert views on the Slavic group structure. Kassian-Dybo's tree suggests that Proto-Slavic first diverged into three branches: Eastern, Western and Southern. The Proto-Slavic break-up is dated to around 100 A.D., which correlates with the archaeological assessment of Slavic population in the early 1st millennium A.D. being spread on a large territory and already not being monolithic. Then, in the 5th and 6th centuries A.D., these three Slavic branches almost simultaneously divided into sub-branches, which corresponds to the fast spread of the Slavs through Eastern Europe and the Balkans during the second half of the 1st millennium A.D. (the so-called Slavicization of Europe). The Slovenian language was excluded from the analysis, as both Ljubljana koine and Literary Slovenian show mixed lexical features of Southern and Western Slavic languages (which could possibly indicate the Western Slavic origin of Slovenian, which for a long time was being influenced on the part of the neighboring Serbo-Croatian dialects), and the quality Swadesh lists were not yet collected for Slovenian dialects. Because of scarcity or unreliability of data, the study also did not cover the so-called Old Novgordian dialect, the Polabian language and some other Slavic lects. The above Kassian-Dybo's research did not take into account the findings by Russian linguist
Andrey Zaliznyak who stated that, until the 14th or 15th century, major language differences were not between the regions occupied by modern Belarus, Russia and Ukraine, but rather between the north-west (around modern Velikiy Novgorod and Pskov) and the center (around modern
Kyiv,
Suzdal,
Rostov,
Moscow as well as Belarus) of the East Slavic territories. The
Old Novgorodian dialect of that time differed from the central East Slavic dialects as well as from all other Slavic languages much more than in later centuries. According to Zaliznyak, the Russian language developed as a convergence of that dialect and the central ones, whereas Ukrainian and Belarusian were continuation of development of the central dialects of East Slavs. Also Russian linguist Sergey Nikolaev, analysing historical development of Slavic dialects' accent system, concluded that a number of other tribes in Kievan Rus came from different Slavic branches and spoke distant Slavic dialects. Zaliznyak and Nikolaev's points mean that there was a convergence stage before the divergence or simultaneously, which was not taken into consideration by Kassian-Dybo's research. Ukrainian linguists (
Stepan Smal-Stotsky,
Ivan Ohienko,
George Shevelov, Yevhen Tymchenko, Vsevolod Hantsov,
Olena Kurylo) deny the existence of a common Old East Slavic language at any time in the past. According to them, the dialects of East Slavic tribes evolved gradually from the common Proto-Slavic language without any intermediate stages.
Linguistic history The following is a summary of the main changes from
Proto-Indo-European (PIE) leading up to the
Common Slavic (CS) period immediately following the
Proto-Slavic language (PS). •
Satemisation: • PIE *ḱ, *ǵ, *ǵʰ → *ś, *ź, *źʰ (→ CS *s, *z, *z) • PIE *kʷ, *gʷ, *gʷʰ → *k, *g, *gʰ •
Ruki rule: Following *r, *u, *k or *i, PIE *s → *š (→ CS *x) • Loss of
voiced aspirates: PIE *bʰ, *dʰ, *gʰ → *b, *d, *g • Merger of *o and *a: PIE *a/*o, *ā/*ō → PS *a, *ā (→ CS *o, *a) • Law of
open syllables: All
closed syllables (syllables ending in a consonant) are eventually eliminated, in the following stages: •
Nasalization: With *N indicating either *n or *m not immediately followed by a vowel: PIE *aN, *eN, *iN, *oN, *uN → *ą, *ę, *į, *ǫ, *ų (→ CS *ǫ, *ę, *ę, *ǫ, *y). (NOTE: *ą *ę etc. indicates a nasalized vowel.) • In a cluster of
obstruent (stop or fricative) + another consonant, the obstruent is deleted unless the cluster can occur word-initially. • (occurs later, see below)
Monophthongization of
diphthongs. • (occurs much later, see below)
Elimination of liquid diphthongs (e.g. *er, *ol when not followed immediately by a vowel). •
First palatalization: *k, *g, *x → CS *č, *ž, *š (pronounced , , respectively) before a front vocalic sound (*e, *ē, *i, *ī, *j). • Iotation: Consonants are
palatalized by an immediately following *j: • sj, *zj → CS *š, *ž • nj, *lj, *rj → CS *ň, *ľ, *ř (pronounced or similar) • tj, *dj → CS *ť, *ď (probably
palatal stops, e.g. , but developing in different ways depending on the language) • bj, *pj, *mj, *wj → *bľ, *pľ, *mľ, *wľ (the
lateral consonant *ľ is mostly lost later on in
West Slavic) • Vowel fronting: After *j or some other palatal sound, back vowels are fronted (*a, *ā, *u, *ū, *ai, *au → *e, *ē, *i, *ī, *ei, *eu). This leads to hard/soft alternations in noun and adjective declensions. • Prothesis: Before a word-initial vowel, *j or *w is usually inserted. •
Monophthongization: *ai, *au, *ei, *eu, *ū → *ē, *ū, *ī, *jū, *ȳ •
Second palatalization: *k, *g, *x → CS *c , *dz, *ś before new *ē (from earlier *ai). *ś later splits into *š (West Slavic), *s (East/South Slavic). • Progressive palatalization (or "third palatalization"): *k, *g, *x → CS *c, *dz, *ś
after *i, *ī in certain circumstances. • Vowel quality shifts: All pairs of long/short vowels become differentiated as well by
vowel quality: • a, *ā → CS *o, *a • e, *ē → CS *e, *ě (originally a low-front sound but eventually raised to in most dialects, developing in divergent ways) • i, *u → CS *ь, *ъ (also written *ĭ, *ŭ; lax vowels as in the English words
pit, put) • ī, *ū, *ȳ → CS *i, *u, *y •
Elimination of liquid diphthongs:
Liquid diphthongs (sequences of vowel plus *l or *r, when not immediately followed by a vowel) are changed so that the syllable becomes
open: • or, *ol, *er, *el → *ro, *lo, *re, *le in
West Slavic. • or, *ol, *er, *el → *oro, *olo, *ere, *olo in
East Slavic. • or, *ol, *er, *el → *rā, *lā, *re, *le in
South Slavic. • Possibly, *ur, *ul, *ir, *il → syllabic *r, *l, *ř, *ľ (then develops in divergent ways). • Development of phonemic tone and
vowel length (independent of vowel quality): Complex developments (see
History of accentual developments in Slavic languages). ==Features==
