+# etymology-db
+This is just a stub from the original [repo](https://github.com/droher/etymology-db)
+All credits go to the original author [David Roher](https://github.com/droher).
+A structured, comprehensive, and multilingual etymology dataset created by parsing Wiktionary's etymology sections. Key features:
+*  4.2+ million etymological relationships between 2.0+ million terms in 3300+ languages/dialects
+*  31 different types of etymological relations, distinguishing between inheritance, borrowing, etc.
+*  Hierarchical data that preserves relationship structures, such as the evolution of a term across languages
+Caveat for people interested in using this for research: all information is pulled directly from Wiktionary via
+semi-structured text parsing, and I've made no effort yet to validate any particular result. That said, I would love
+for this to be useful, so please raise an issue if you have questions.
+Here is a description of the table schema:
+| Column Name | Description |
+|-----------------|----------------------------------------------------------------------------------------------------------------------------------------|
+| term_id | A hash of the term and its language. |
+| lang | The language/dialect of the term. |
+| term | The term itself. Usually a word, but can also be a prefix or a multi-word expression, hence "term" instead of word. |
+| reltype | The kind of etymological relation being specified (see below for details on each possible value). |
+| related_term_id | A hash of the related term and its language (useful for assembling relationships across multiple terms). |
+| related_lang | The language/dialect of the related term. NULL for parent root nodes. |
+| related_term | The term that is etymologically related to the original entry. NULL for parent root nodes. |
+| position | Zero-indexed position of the term when the relation is made up of multiple terms (e.g. a compound). |
+| group_tag | Randomly generated ID. populated only for the root nodes of nested relationships. |
+| parent_tag | If this relation is inside of a nested structure, this will be populated with the `group_tag` of its immediate parent. NULL otherwise. |
+| parent_position | Zero-indexed position of the relation inside of its nested structure. NULL if not nested. |
+And here is a description of each relation type. Note that these are all derived directly from Wiktionary's etymology templates -- all rows are classified according to the name of the template from which the info was extracted, and no further inferences are made. The only exception to this is the `group` relations, which are based on formulaic and reoccuring patterns in natural language sections.
+| Relation Type | Description |
+|-----------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| inherited_from | Indicates that `term` has an unbroken chain of inheritance from `related_term`. |
+| borrowed_from | Indicates that `term` is a loanword borrowed during the time the borrowing language was spoken. |
+| derived_from | A catch-all for a derivation relationship that is not specifically inherited/borrowed. |
+| learned_borrowing_from | Borrowed from the original language via atypical ("inorganic") means of language contact. |
+| semi_learned_borrowing_from | Borrowed words that have been partly reshaped by later sound change or analogy with inherited terms. /
+| orthographic_borrowing_from | Borrows the spelling of `related_term` but not the pronunciation. |
+| unadapted_borrowing_from | Borrowed words that have not been conformed to the morpho-syntactic, phonological and/or phonotactical rules of the target language. |
+| root | Constructed root(s) of `term` in  a theoretical ancestor language, e.g. Proto-Indo-European.  |
+| has_prefix | Indicates that `term` is partially based on the prefix `related_term`. |
+| has_prefix_with_root | `related_term` is the term attached to a prefix (not necessarily a suffix, e.g. "normal" in "abnormal") |
+| has_suffix | Same as above, but for suffixes. |
+| has_suffix_with_root | Same as above, but for suffixes. |
+| has_confix | A confix is a term whose first element is a prefix and whose last is a suffix. Position 0 of a confix is the prefix, and the last position is the suffix. |
+| has_affix | Affix is the general form of prefix/suffix/confix and indicates some kind of compound structure without further detail. |
+| compound_of | Indicates that `related_term` is the `position`-indexed term of a compound that makes up `term`. Used interchangeably with affix above. |
+| back-formation_from | Indicates that `term` was formed from `related_term` by removing a prefix/suffix. |
+| doublet_with | Indicates that `term` and `related_term` have the same etymological origin, especially when the relationship is unintuitive. |
+| is_onomatopoeic | Indicates that `term` is an onomatopoeia (a word form from a sound associated with its meaning). |
+| calque_of | Indicates that `term` is borrowed from `related_term` via a direct word-for-word or root-for-root translation. |
+| semantic_loan_of | Special case of calques in which the word already existed but a new meaning was added. |
+| named_after | Indicates that `term` is based on the name of the person `related_term` (an eponym). |
+| phono-semantic_matching_of | Indicates that `term` and `related_term` have very similar sounds and meanings in both languages. |
+| etymologically_related_to | A catch-all indicating `term` and `related_term` are etymologically related without any further context provided. |
+| blend_of | Indicates that `term` is made up of a blend of `related_term` and the related terms in other `position`s. This differs from a compound in that the beginning of one word is combined with the ending of another. |
+| clipping_of | Indicates that `term` is a  _spoken_ shortened version of `related_term` without any semantic difference. |
+| abbreviation_of | Indicates that `term` is a _written_ shortened version of `related_term` without any semantic difference. |
+| initialism_of | Indicates that `term` is based on the initials of  `related_term`. |
+| cognate_of | Indicates that `term` and `related_term` sound/mean similar things, but no direct ancestral relationship exists. |
+| group_affix_root | A node that groups together rows that, when combined, form an affix.  |
+| group_related_root | A node that groups together rows in which `related_terms` are not just related to the `term`, but to each other as well. |
+| group_derived_root | A node that groups together rows that, when combined, form an unbroken chain of inheritance (in reverse chronological order). |
