An Open-source Online Reverse Dictionary [link]

What Is a Reverse Dictionary?

Opposite to a regular (forward) dictionary that provides definitions for query words, a reverse dictionary returns words semantically matching the query descriptions.

What Can a Reverse Dictionary Do?

• Solve the tip-of-the-tongue problem, the phenomenon of failing to retrieve a word from memory
• Help new language learners
• Help word selection (or word dictionary) anomia patients, people who can recognize and describe an object but fail to name it due to neurological disorder
