Poets and other writers are generally word nerds, which is to say that we have our favorite words that we love to us. For poets, the word is often just as much about sound as it is about its definition, and obscure is only sometimes better. Save the Word is trying to encourage people to adopt words. According to them, ninety percent of our communication uses only 7,000 words.
Go out there and adopt a word. Looking at what they have available right now, it looks like some of the more fun words include drollic (pertaining to puppet shows), riviation (fishing), and avunculize (to act as an uncle).
