This is a great in depth study into the whats in a word(letter) syndrome. There is a small pile of weapons across the Ethnographic stratum which have such pickled wording and spelling as to be a veritable knot of muddled and mixed up mess. It is a brave researcher who will take on any of this centuries old train crash.. In his dissertation Ariel shows how to go about unpicking the puzzle. I can think of a dozen or more twisted or misapplied words for various weapons that we know little about..and noted by Jim above . The word Nimcha, for example, is just one baffling arrangement...often caused by Ethnographics experts and authors who transcribe these errors into their work from previous authors.
Perhaps the thread should be better termed ..the.. What's in a Word
and any such muddles can be added onto it and see where the thread is after a year or two... it could be an epic.
