| # EverFlip Multilingual Flashcard Corpus |
|
|
| **24,164 flashcards across 81 languages**, organised into 1,573 themed decks and exam ladders (JLPT, HSK, TOPIK, DELE / DELF / Goethe / CILS / CAPLE). |
|
|
| Each card is a factual lexical correspondence — a word or phrase in the target language, its reading (for non-Latin scripts), and its English meaning. |
|
|
| ## Files |
| - `cards.csv` — every card (24,164 rows): `language_code, language, deck_slug, deck_name, front, meaning_en, back_raw, translation_raw`. Use **`meaning_en`** for the normalized English meaning (it resolves the field across Latin and non-Latin scripts). |
| - `decks.csv` — deck catalogue (1,573 rows). |
| - `languages.csv` — language catalogue (81 rows). |
| - `datapackage.json` — [frictionlessdata.io](https://frictionlessdata.io) Tabular Data Package descriptor. |
