A cool new feature from One Look

One Look, the site that allows you to search dozens of dictionaries and similar sources at once, has a new reverse lookup feature.

It works pretty well. I can never remember how to spell onomatopoeia -- the term for words that sound like the sounds they represent. So I typed into the reverse lookup "word sounds like sound it represents." Onomatopoeia turned up as No. 31 on the suggested list after heterography, Cherokee language, literation and a whole bunch of onomatopoetic words. But that's good enough for me.
