I'm your host, Forthright. Since 1996, I have compiled word lists in order to spread the joy of the English language. Here, you will find the International House of Logorrhea (an online dictionary of obscure and rare words), the Compendium of Lost Words (a compilation of ultra-rare forgotten words), and many other glossaries, word lists, essays, and other language and etymology resources. If you have a question, comment, addition, or suggestion, feel free to e-mail me. Happy word-hunting!
