If anyone else here is a fan of roots, you can take a look at the site of Professor Gerhard Köbler, from the University of Innsbruck, Austria: http://www.koeblergerhard.de/ Here's the dicionary of Indo-european roots: http://www.koeblergerhard.de/idgwbhin.html Some time ago, I sent an email to him asking some questions and he was very kind and helpful. cheers
