A while ago I stumbled on a list of science fiction with linguistic themes. I'd quite like to re-find the list, but I remember little more about it than that it mentioned Babel-17 by Delany, and a short story by James Tiptree, Jr.; and, on the assumption that it's hard to find the list based just on those recollections, I'm asking here instead what the Tiptree story was.
My recollection is that this story revolved around a version of the Sapir–Whorf hypothesis, and that much of it was set in a jungle—I think I remember characters disembarking from, or fleeing to, a canoe at some point—but I can't remember more about the plot than that. I read the story probably about 15 years ago, in a compilation of short stories, but unfortunately I can't even remember whether the compilation was entirely of Tiptree stories, or whether it had many sci-fi authors' stories. Whatever it was, I think it was a later compilation, not the original publication of the story.
