I used the word "often" in the sense of "many times" or "frequently." At no point did I claim that Burroughs (or Uncle John Carter or Gahan of Gathol) always did anything. In fact, I gave an example of the Manatorian names in which I imagined that the hyphens could have been Uncle Jack's attempt at indicating vowel length. (John Carter never claims to be a scholar). Indeed, when I used the word "imagination" I meant it in the sense of "creativity" or "forming new ideas." At no point did I actually make a hypothesis. I'm interested in creativity, imagination, and art as they interact with language -- in this case, the romantic idea of an ancient Martian language. Also, I'm interested in making jokes about Ghek action figures. I wonder whether there are any on Ebay.
