I have everything but the last letter of 25A SCE-. I know that C is the "misprint" letter (as it must be for the "non-dictionary compound") but the only alternative word I can find is "SWEY" a Scottish form of "sway" ("reel"). So is Y my final missing letter? I can't make any sense of the clue. SKEY ought to be the alternative word (to my mind), but it doesn't exist!
