About Reverse Wiktionary
Reverse Wiktionary is a semantic search interface for finding words from natural-language descriptions. In plain English: you describe a meaning, and Reverse Wiktionary finds words, across more than 4,600 languages, that match what you are describing. It is meant for anyone interested in exploring language, from writers to researchers to the merely curious.
