Balto-Slavic languages Study Guide

📖 Core Concepts Balto‑Slavic branch – a sub‑family of Indo‑European that unites Baltic (Lithuanian, Latvian, Old Prussian) and Slavic (Russian, Polish, etc.). Proto‑Balto‑Slavic (PBS) – hypothetical ancestor reconstructed by the comparative method from Proto‑Indo‑European (PIE). Shared innovations – phonological, morphological, and accentual features that appear in both Baltic and Slavic but not in any other IE branch (e.g., Winter’s law, Ruki law, ablative ‑ād). Genetic vs. contact debate – early scholars argued for pure contact; modern consensus accepts a genetic relationship plus later contact. Classification models Bipartite: Baltic ↔ Slavic. Three‑branch: East Baltic, West Baltic, Slavic (Kortlandt). Chronology – tree‑dating places the Baltic/Slavic split around 1400 BCE (Gray & Atkinson). Historical expansion – Proto‑Slavic spreads rapidly in the 6th–7th c. CE, replacing Baltic dialects far east (hydronymic evidence). --- 📌 Must Remember Balto‑Slavic = Baltic + Slavic; they share phonological, lexical, morphosyntactic, accentual traits. Winter’s law: vowels lengthen before PIE non‑breathy voiced consonants; subsequent merger of breathy‑voiced consonants → plain voiced. Ruki law: s → š after r, u, k, i (later š → x in Slavic before back vowels). Satemization: PIE palatovelars (ḱ, ǵ, ǵʰ) → sibilants ś, ź, ź; labiovelars lose labialization. Morphological replacements Genitive ‑osyo → Ablative ‑ād. Instrumental singular ‑ān (from ‑āmi). Instrumental plural ‑mis (e.g., Lith. sūnumìs, OCS synъmi). Accentual register: long syllables split into acute (glottalized) vs circumflex (non‑glottalized). Split date: 1400 BCE; Proto‑Slavic separation: 1500–1000 BCE (archaeology, glottochronology). Hydronymic clue: Baltic names once reached Moscow before Slavic takeover. --- 🔄 Key Processes Reconstruction of PBS Collect cognates in Baltic & Slavic. Apply known PIE sound laws. Identify shared innovations (Winter’s law, Ruki, etc.) as evidence of a common ancestor. Sound‑change cascade Winter’s law → vowel lengthening. Breathy‑voiced merger → plain voiced consonants. Satemization → palatal sibilants. Ruki law → s → š after r, u, k, i. Accent retraction (Hirt’s law) → stress moves leftward when a laryngeal follows. Morphological innovation Replace PIE genitive ‑osyo with ‑ād (ablative). Introduce instrumental ‑ān (sing.) and ‑mis (pl.). Historical spread 1500‑1000 BCE: PBS dialect splits, Proto‑Slavic begins diverging. 6th–7th c. CE: rapid Slavic expansion, supplanting eastern Baltic dialects (evidenced by hydronyms). --- 🔍 Key Comparisons Genetic relationship vs. Intensive contact Genetic: shared innovations that cannot be explained by borrowing alone (Winter’s law, ablative ‑ād). Contact: lexical borrowing, areal features without systematic sound‑law correspondences. East Baltic vs. West Baltic East: Lithuanian, Latvian – retain most PBS innovations. West: Old Prussian – extinct, shows some divergent developments. Baltic vs. Slavic innovations Baltic: retains the acute–circumflex register more robustly. Slavic: adds the later š → x before back vowels. Three‑branch model vs. bipartite model Three‑branch: treats East Baltic, West Baltic, and Slavic as equally distant. Bipartite: groups all Baltic together, then Slavic. --- ⚠️ Common Misunderstandings “All shared words are inherited.” Many lexical items are still different; only the innovations (sound laws, morphology) prove common ancestry. Confusing Ruki law with the later Slavic š → x shift. Ruki applies to all Balto‑Slavic; the š → x change occurs only in Slavic before back vowels. Dating the split to the early Common Era. Tree‑dating and archaeological data place it around 1400 BCE, not the CE period. Assuming West Baltic languages are still spoken. Old Prussian is extinct; only East Baltic survives today. --- 🧠 Mental Models / Intuition “Common trunk, later branches” – imagine a single PBS trunk that splits into a Baltic limb (which stays close to the trunk) and a Slavic limb (which quickly shoots off and spreads). Sound‑law filter – think of each innovation (Winter’s law, Ruki, Satemization) as a filter that all descendants must pass; if a language lacks a filter, it likely branched before that change. --- 🚩 Exceptions & Edge Cases Vowel insertion: i is the default high vowel before PIE syllabic sonorants; u occurs only occasionally. Register distinction: not all Baltic languages preserve both acute and circumflex equally; some West Baltic forms have merged them. Instrumental plural ‑mis: appears in Baltic and Old Church Slavonic, but later Slavic languages often replace it with other forms. --- 📍 When to Use Which Choosing a classification model – use the three‑branch model when the question stresses equidistance of East/West Baltic and Slavic (e.g., Kortlandt’s work). Opt for the bipartite model for textbook‑style overviews. Applying sound laws – start with Winter’s law for vowel length, then Satemization, followed by Ruki; this order mirrors the historical sequence in PBS. Using evidence for genetic relationship – prioritize morphological innovations (ablative ‑ād, instrumental ‑ān/‑mis) over lexical borrowing when arguing for a common ancestor. --- 👀 Patterns to Recognize Acute vs. circumflex markers on long vowels → indicates PBS register distinction. Hydronymic suffixes (e.g., ‑ava, ‑eja) extending eastward → clue to former Baltic presence. Instrumental plural ‑mis appearing in both Lithuanian and OCS → a hallmark of PBS morphology. Ruki environment (r, u, k, i + s) → expect š (or later x in Slavic). --- 🗂️ Exam Traps Distractor: “Baltic and Slavic share the same genitive ending ‑osyo.” Why tempting: PIE genitive is well‑known. Why wrong: PBS replaces ‑osyo with ablative ‑ād. Distractor: “Satemization is a Slavic‑only change.” Why tempting: Slavic languages display many sibilants. Why wrong: Satemization is a Balto‑Slavic (and broader Satem) innovation affecting both branches. Distractor: “The split of Baltic and Slavic occurred in the 5th c. CE.” Why tempting: Aligns with the rapid Slavic expansion. Why wrong: Tree‑dating points to 1400 BCE. Distractor: “All Baltic languages retain the PIE ‑osyo genitive.” Why tempting: PIE forms are often assumed to survive. Why wrong: PBS uniformly replaces it with ‑ād in both Baltic and Slavic. Distractor: “West Baltic languages show the same acute–circumflex pattern as East Baltic.” Why tempting: The register distinction is a core PBS trait. Why wrong: West Baltic (Old Prussian) has merged or altered the register in several cases.
