Call me old fashioned if you will, but I still like to use a nifty little writing helper called WordWeb.
Part of WordWeb’s beauty is in its simplicity, and ease of use. It lurks quietly in the background at the bottom of your screen until you get stumped for a word or phrase. Then it’s immediately on call with helpful sources like a built-in dictionary, thesaurus, Wikipedia, Wiktionary, etc..
I use it a lot when I get stumped for a word, phrase, or idea.
