Mafia 84. Memorized it, turned it in, forgot it!

I'm more than sure that's the case. Perhaps the "cl-" that resulted from "sd-" is just a coincidence, because the other elements aren't clarified in that way.

And by the way, since I have a vote from Hekasan, I'd like to ask him a question: "Why isn't he solving the clue?" and "Why is he happy that psychology pointed him to me?" Hekasan? I'm at least trying to do something, and you just cast your vote and left, complaining about the "difficult clue." That's not how things are done.
