Here's the reason I haven't been updating my website or sending out my newsletter for a long time — I've been working on a dictionary. The Indo-European Cognate Dictionary, to be precise. It's out now, and I'm really excited about it. Excited that it's done, excited than I now have a physical copy that I can use myself, excited because — hey, I've written a dictionary! It weighs in at 545 pages, and it's available in the usual digital formats, except Kindle.
