📖 Vision & Overview

When preparing for major language proficiency examinations or daily vocabulary acquisition, finding well-formatted, complete, and typo-free word lists is often surprisingly difficult. Many resources online suffer from corrupted encodings, missing phonetics, fragmented files, or inconsistent column layouts.

English Vocabulary Vault is an open-source initiative designed to provide a unified, clean, and comprehensive collection of English vocabulary datasets:

• Massive Scope: Over 960+ distinct vocabulary books covering K-12 schooling, college exams (CET-4/6, TEM-4/8), postgraduate & PhD entrances, overseas examinations (IELTS, TOEFL, GRE, GMAT, SAT), and specialized industry English.
• High Quality: Standardized in .xlsx and .txt formats with International Phonetic Alphabet (IPA) transcriptions and comprehensive contextual definitions.
• Ready for Anki & Flashcards: Engineered for instant zero-hassle import into spaced repetition software (Anki, Quizlet, RemNote, Eudic).
