Reverse Vocabulary is a web and Android vocabulary service that allows users to learn vocabulary by looking at a word and inputting its meaning directly. Unlike standard vocabulary apps that display both the word and its meaning, it presents only the word first and requires the user to input the meaning they have memorized, thereby encouraging active recall learning.

Key Features
- Create and manage separate English and Korean vocabulary lists
- Register and edit words, meanings, and synonyms
- Drag to change the order of the vocabulary list and words
- Flip-card style memorization learning
- Manage and reset completed words
- Reverse testing where users look at the word and input its meaning
- Flexible answer scoring based on semantic similarity
- Provides detailed results including correct answer status, score, and the most similar meaning
- Check test records by word and overall learning results
- Search for Korean definitions and related words using Woorimalsaem

Learning Method
1. Create an English or Korean vocabulary list.

2. Register the words and meanings to be studied.

3. Flip over cards on the memorization screen to check the content.

4. Directly input the meaning of the presented word on the test screen. 5. The entered answer is graded by comparing it with the registered meanings and synonyms.

6. Check your score and incorrect answers on the results screen and review them.

7. You can mark words you have sufficiently mastered as "memorized" to exclude them from further study.

Features

The Reverse Vocabulary list does not judge answers based solely on simple string matching. It uses a text similarity-based scoring method to evaluate answers that are semantically close, even if the expressions are not exactly the same. Since multiple meanings and synonyms are compared together, answers containing natural sentences or similar expressions may be reflected in the learning results.
