A working reverse dictionary (hosted by Onelook.com) is one of the most useful sites out there. We've all had those moments when we know there's a word for some concept, but we don't know what it is. We need something more than a thesaurus, because we don't know an equivalent word. Onelook.com's reverse dictionary helps. You can even enter wildcards, if you know what part of the word looks like.

I'm not a professional writer, but I write for fun. This tool is indispensable.
