With One Look you can type in your own made-up definition and it will provide you with a list of words that are a possible match. It's like using a thesaurus, except you can be more abstract in how you search for useful words.For example, I typed in the description "scream with meaning" and it returned with one hundred words including screak, roar, ululate, rend, bleat and vociferate. The range of results also included several names including Skeet Ulrich, Jamie Lee Curtis, and Edvard Munch. Each result comes with a set of links to its entry within popular online dictionaries so you can judge how useful it is for your purposes.
