I'm struggling with 17, which (by elimination) I believe to ne normal. Two words fit the space: one is a tongue and the other means magical, but I can't get anywhere with the wordplay. I'm guessing that the 6 letters + W anag into something … but what? I have the structure and the 8-word "further information" (so far, bereft of meaning). And the poem is lost in the jungle so far.
