I use the http://elderscrolls.wikia.com/wiki/Dragon_language to choose my names. My Daedric Dagger (Soul Trap, 1 second) is named Sil Feyn - translates as Soul Bane.
I thought I read a post by someone here that you could interrupt the enchanting process and somehow get away with naming your item without actually enchanting it. Does anyone know if that's true? I just want to name my gear, but I don't want to enchant it. It's silly you can't name whatever you smith as well.
