Thanks to the mighty Metafilter I came across a new word website today. It is called Wordnik. According to the website they are "ongoing project devoted to discovering all the words and everything about them." I like this site. Check out the entry for frog. It gives you the word's appearance in public domain documents at Gutenberg site, several definition options, a recorded pronunciation, occurrences of the word in Twitter posts, synonyms and images from Flickr. Pretty impressive.
