I've been reading Mark Horne's new short biography of JRRT, part of the 'Christian Encounters' series, and came across the following curious statement re. Tolkien and his friend Christopher Wiseman:
"Wiseman shared Tolkien's interest in language and shared in his development of private languages." (Horne, p. 23)
This was news to me, and I doubt its accuracy -- certainly Wiseman didn't say anything about inventing languages when I met him, but perhaps the topic just didn't come up. Does anyone have a source for Wiseman's having played a role in Tolkien's invention of Gnomish or Qenya? Horne has a superscript at the end of the paragraph crediting Jn Garth's book, but that seems to apply only to the final sentence in the paragraph, not this one.
