Being a massive word-hound, I was incredibly tickled by this site when my brother sent it to me. (Many thanks, by the way!) http://www.savethewords.org/
I have so far decided that I need to find ways to use antipelargy (‘reciprocal or mutual kindness, the love of a child for a parent’), hirquitalliency (‘strength of voice’), and stibogram (‘a graphic record of footprints’).
And for other word-joy, I recommend A.Word.A.Day newsletter, delivered straight to your inbox courtesy of wordsmith.org
