Last weekend, there was this sales man who dropped into my place to sell Oxford dictionary and like stuff. His selling point was that the dictionary also features a “Reverse Dictionary” and hence the origin of this post.
A reverse dictionary lets you describe a concept and get back a list of words and phrases related to that concept. Your description can be a few words, a sentence, a question, or even just a single word.
After some internet research, One Look Reverse Dictionary seems to be one of the most comprehensive dictionaries. So here they search for words having definitions that match the search term given. It could be a quite cool thing because many a times, it so happens that you know the meaning but don’t know the word to describe it. The reverse dictionary would help here. What I am not sure of is that, there could be multiple ways of describing a word and how the reverse dictionary takes care of it.
