Cross-Lingual Analysis Guide
What is this guide?
A reference for the six cross-lingual analysis tools in RunoVerse. Each section below describes one tool, the data behind it, and links directly to the explorer page.
How to navigate
Scroll through the sections or use your browser's find (Ctrl/Cmd+F) to jump to a topic. Each section ends with a direct link to the corresponding explorer. The tools range from surface-level string matching (Cognates, Shared Vocabulary) to deeper semantic analysis (Concepts, Thesaurus).

Estonian and Finnish both belong to the Finnic language family. These tools help explore the linguistic connections between the two traditions — cognate words, shared vocabulary, AI notes on word origins, and semantic concepts that bridge the language divide.
Cognate Explorer
Browse 4,748 automatically proposed Estonian–Finnish cognate pairs. Cognates are words in the two languages that descend from a common ancestor, but the pipeline finds its candidates from spelling, English glosses and AI etymology signals, so the set also contains shared loans and translation equivalents. Treat the pairs as candidates to check rather than as established cognates.
The cognate pairs were identified using three discovery methods:
- Shared forms – 186 pairs where one and the same form is attested in both traditions with identical spelling; the Cognate Explorer labels these Shared.
- Near-exact matches – 2,013 pairs with minor orthographic differences, capturing systematic sound correspondences between Estonian and Finnish (such as vowel length differences or consonant gradation).
- Translation-bridged pairs – 2,714 pairs where both an Estonian and a Finnish word share the same English translation, suggesting a common meaning even when the surface forms have diverged further.
The interactive network visualization shows how cognate pairs connect into larger word families. You can filter results by match type or search for specific words to see their cross-lingual connections.
Open Cognate Explorer →AI Etymology Notes
Browse what the DeepSeek AI wrote into the etymology field while annotating the runosong corpora. The notes are gathered into 49,000 groups by the form each note mentions; the groups list 174,878 lemmas in all, 104,637 of them different. A group shows that AI notes mention the same form, not that its words share a verified origin. The notes are raw AI output and contain many errors.
- Side-by-side comparison – press Compare, then click two groups to set them side by side: how many members each has, how many of them are Estonian and how many Finnish lemmas, their total frequency and their part-of-speech mix.
- Cross-lingual groupings – see the Estonian and Finnish lemmas whose AI notes mention the same form. A shared mention is a lead to check, not evidence of a shared origin.
- Corpus frequency data – open a group to see each member word with its frequency across the four corpora (SKVR, KR, JR, ERAB), its part of speech and its corpus distribution.
Shared Vocabulary
Explore the 1,240 lemmas that appear in both the Estonian and Finnish corpora as identical string forms. The match is one of spelling: identical forms often do reflect common Finnic inheritance, but they can equally be later loans or chance resemblances, so this is a starting point for comparison rather than a verified core vocabulary.
- Identical forms – 1,240 lemmas found in both Estonian (ERAB) and Finnish (SKVR, JR) sources with the exact same spelling.
- Cognate pairs – the full set of 4,748 automatically discovered Estonian–Finnish cognate pairs, including near-matches and translation-bridged connections beyond the identical forms.
- Interactive visualizations – compare the shared Finnic vocabulary with charts showing frequency distributions, part-of-speech breakdowns, and the overlap between the two corpora.
Concept Browser
Browse 483,025 English semantic concepts mapped to Finnic runosong wordforms. The Concept Browser functions as a cross-lingual reverse dictionary: enter an English word or meaning, and discover which Estonian and Finnish runosong lemmas express that concept.
- Cross-lingual discovery – find out how the same concept is expressed in Estonian and Finnish runosong vocabulary, revealing both shared terms and language-specific expressions.
- Semantic search – enter any English word to find all related runosong vocabulary. For example, searching “mother” reveals the various Estonian and Finnish words for mother used across the poetic traditions.
- Frequency data – each concept shows how many lemmas and word forms map to it, along with corpus frequency information from both traditions.
Thematic Vocabulary
Browse Finnic runosong vocabulary organized by 25 translation-based thesaurus domains, providing a thematic overview of the poetic word-world shared by the Estonian and Finnish corpora. Domains include Family, Nature, Animals, War, Magic, Religion, Food, Clothing, Body, and others.
- Semantic domains – 25 thematic categories organize the vocabulary into meaningful groups, making it easy to explore what words the runosong traditions used to talk about specific topics.
- Cross-lingual comparisons – for each domain, see which words exist in both the Estonian and Finnish corpora and which are unique to one, revealing how the two poetic vocabularies overlap and diverge.
- Frequency and distribution – each thematic category shows word counts and corpus frequency data, indicating which semantic domains dominate the runosong vocabulary and how usage patterns differ between the corpora.
